Phase IIa trial of trastuzumab emtansine with pertuzumab for patients with human epidermal growth factor receptor 2-positive, locally advanced, or metastatic breast cancer.
J Clin Oncol. 2014; 32(14):1437-44 [PubMed] Related Publications
PURPOSE: Our phase IIa study characterized the safety and efficacy of two human epidermal growth factor receptor 2 (HER2) -targeted agents, trastuzumab emtansine (T-DM1) and pertuzumab, in patients with HER2-positive metastatic breast cancer (MBC).
PATIENTS AND METHODS: Patients with HER2-positive locally advanced breast cancer or MBC were treated with 3.6 mg/kg T-DM1 plus pertuzumab (840-mg loading dose, then 420 mg subsequently) once every 3 weeks. The primary efficacy end point was investigator-assessed objective response rate (ORR).
RESULTS: Sixty-four patients (43 patients in the second-line or greater setting [advanced MBC]; 21 patients in the first-line setting [first-line MBC]) were enrolled. Patients with advanced MBC had received trastuzumab and a median of six prior nonhormonal treatments for MBC; 86% of first-line MBC patients had received trastuzumab in the (neo)adjuvant setting. The ORR was 41% overall, 33% in patients with advanced MBC, and 57% in first-line patients. Median progression-free survival was 6.6, 5.5, and 7.7 months, respectively. The most common adverse events were fatigue (61%), nausea (50%), and diarrhea (39%). The most frequent grade ≥ 3 adverse events were thrombocytopenia (13%), fatigue (11%), and liver enzyme elevations (increased ALT: 9%; increased AST: 9%). One patient had left ventricular ejection fraction of less than 40% after study drug discontinuation. Exploratory biomarker analyses demonstrated that patients with above-median tumor HER2 mRNA levels had a numerically higher ORR than patients with below-median levels (44% v 33%, respectively).
CONCLUSION: T-DM1 and pertuzumab can be combined at full doses with no unexpected toxicities. The preliminary efficacy in patients in the first-line and advanced MBC settings warrants further investigation.

Patient-reported outcome results from the open-label phase III AURELIA trial evaluating bevacizumab-containing therapy for platinum-resistant ovarian cancer.
J Clin Oncol. 2014; 32(13):1309-16 [PubMed] Related Publications
PURPOSE: To determine the effects of bevacizumab on patient-reported outcomes (PROs; secondary end point) in the AURELIA trial.
PATIENTS AND METHODS: Patients with platinum-resistant ovarian cancer were randomly assigned to chemotherapy alone (CT) or with bevacizumab (BEV-CT). PROs were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Ovarian Cancer Module 28 (EORTC QLQ-OV28) and Functional Assessment of Cancer Therapy-Ovarian Cancer symptom index (FOSI) at baseline and every two or three cycles (8/9 weeks) until disease progression. The primary PRO hypothesis was that more patients receiving BEV-CT than CT would achieve at least a 15% (≥ 15-point) absolute improvement on the QLQ-OV28 abdominal/GI symptom subscale (items 31-36) at week 8/9. Patients with missing week 8/9 questionnaires were included as unimproved. Questionnaires from all assessments until disease progression were analyzed using mixed-model repeated-measures (MMRM) analysis. Sensitivity analyses were used to determine the effects of differing assumptions and methods for missing data.
RESULTS: Baseline questionnaires were available from 89% of 361 randomly assigned patients. More BEV-CT than CT patients achieved a ≥ 15% improvement in abdominal/GI symptoms at week 8/9 (primary PRO end point, 21.9% v 9.3%; difference, 12.7%; 95% CI, 4.4 to 20.9; P = .002). MMRM analysis covering all time points also favored BEV-CT (difference, 6.4 points; 95% CI, 1.3 to 11.6; P = .015). More BEV-CT than CT patients achieved ≥ 15% improvement in FOSI at week 8/9 (12.2% v 3.1%; difference, 9.0%; 95% CI, 2.9% to 15.2%; P = .003). Sensitivity analyses gave similar results and conclusions.
CONCLUSION: Bevacizumab increased the proportion of patients achieving a 15% improvement in patient-reported abdominal/GI symptoms during chemotherapy for platinum-resistant ovarian cancer.

Long-term tolerability and efficacy of degarelix: 5-year results from a phase III extension trial with a 1-arm crossover from leuprolide to degarelix.
Urology. 2014; 83(5):1122-8 [PubMed] Related Publications
OBJECTIVE: To demonstrate the safety and efficacy of up to 5 years of degarelix treatment and the effects of crossing over from leuprolide to degarelix in the extension phase of a phase III pivotal 1-year trial.
METHODS: Patients receiving degarelix who completed the 1-year trial continued on 80 mg (n = 125) or 160 mg (n = 126) maintenance doses. Patients who received leuprolide were rerandomized to degarelix 240/80 mg (n = 69) or 240/160 mg (n = 65). Safety and tolerability were assessed (primary end point), as well as testosterone and prostate-specific antigen levels and prostate-specific antigen progression-free survival (secondary end points).
RESULTS: Adverse event frequency was similar between both the groups. Adverse events included initial injection site reactions, hot flushes, and increased weight. Testosterone and prostate-specific antigen values during the extension study were similar to those seen during the 1-year trial in patients who continued on degarelix or crossed over from leuprolide. The prostate-specific antigen progression-free survival hazard rate was decreased significantly after the crossover in the leuprolide to degarelix group (from 0.20 to 0.09; P = .002), whereas in patients who continued on degarelix, the rate did not change significantly. In patients with baseline prostate-specific antigen >20 ng/mL, the same hazard rate change pattern was observed on crossover (from 0.38 to 0.19; P = .019).
CONCLUSION: Degarelix was well tolerated; no safety concerns were identified. The significant prostate-specific antigen progression-free survival benefit established for degarelix over leuprolide during year 1 remained consistent at 5 years.

Neoadjuvant and adjuvant trastuzumab in patients with HER2-positive locally advanced breast cancer (NOAH): follow-up of a randomised controlled superiority trial with a parallel HER2-negative cohort.
Lancet Oncol. 2014; 15(6):640-7 [PubMed] Related Publications
BACKGROUND: In our randomised, controlled, phase 3 trial NeOAdjuvant Herceptin (NOAH) trial in women with HER2-positive locally advanced or inflammatory breast cancer, neoadjuvant trastuzumab significantly improved pathological complete response rate and event-free survival. We report updated results from our primary analysis to establish the long-term benefit of trastuzumab-containing neoadjuvant therapy.
METHODS: We did this multicentre, open-label, randomised trial in women with HER2-positive locally advanced or inflammatory breast cancer. Participants were randomly assigned (1:1), by computer program with a minimisation technique, to receive neoadjuvant chemotherapy alone or with 1 year of trastuzumab (concurrently with neoadjuvant chemotherapy and continued after surgery). A parallel group with HER2-negative disease was included and received neoadjuvant chemotherapy alone. Our primary endpoint was event-free survival. Analysis was by intention to treat. This study is registered at www.controlled-trials.com, ISRCTN86043495.
FINDINGS: Between June 20, 2002, and Dec 12, 2005, we enrolled 235 patients with HER2-positive disease, of whom 118 received chemotherapy alone and 117 received chemotherapy plus trastuzumab. 99 additional patients with HER2-negative disease were included in the parallel cohort. After a median follow-up of 5.4 years (IQR 3.1-6.8) the event-free-survival benefit from the addition of trastuzumab to chemotherapy was maintained in patients with HER2-positive disease. 5 year event-free survival was 58% (95% CI 48-66) in patients in the trastuzumab group and 43% (34-52) in those in the chemotherapy group; the unadjusted hazard ratio (HR) for event-free survival between the two randomised HER2-positive treatment groups was 0.64 (95% CI 0.44-0.93; two-sided log-rank p=0.016). Event-free survival was strongly associated with pathological complete remission in patients given trastuzumab. Of the 68 patients with a pathological complete response (45 with trastuzumab and 23 with chemotherapy alone), the HR for event-free survival between those with and without trastuzumab was 0.29 (95% CI 0.11-0.78). During follow-up only four cardiovascular adverse events were regarded by the investigator to be drug-related (grade 2 lymphostasis and grade 2 lymphoedema, each in one patient in the trastuzumab group, and grade 2 thrombosis and grade 2 deep vein thrombosis, each in one patient in the chemotherapy-alone group).
INTERPRETATION: These results show a sustained benefit in event-free survival from trastuzumab-containing neoadjuvant therapy followed by adjuvant trastuzumab in patients with locally advanced or inflammatory breast cancer, and provide new insight into the association between pathological complete remission and long-term outcomes in HER2-positive disease.

Randomized multicentre trial of gadoxetic acid-enhanced MRI versus conventional MRI or CT in the staging of colorectal cancer liver metastases.
Br J Surg. 2014; 101(6):613-21 [PubMed] Related Publications
BACKGROUND: This multicentre international randomized trial compared the impact of gadoxetic acid-enhanced magnetic resonance imaging (MRI), MRI with extracellular contrast medium (ECCM-MRI) and contrast-enhanced computed tomography (CE-CT) as a first-line imaging method in patients with suspected colorectal cancer liver metastases (CRCLM).
METHODS: Between October 2008 and September 2010, patients with suspected CRCLM were randomized to one of the three imaging modalities. The primary endpoint was the proportion of patients for whom further imaging after initial imaging was required for a confident diagnosis. Secondary variables included confidence in the therapeutic decision, intraoperative deviations from the initial imaging-based surgical plan as a result of additional operative findings, and diagnostic efficacy of the imaging modalities versus intraoperative and pathological extent of the disease.
RESULTS: A total of 360 patients were enrolled. Efficacy was analysed in 342 patients (118, 112 and 112 with gadoxetic acid-enhanced MRI, ECCM-MRI and CE-CT respectively as the initial imaging procedure). Further imaging was required in 0 of 118, 19 (17.0 per cent) of 112 and 44 (39.3 per cent) of 112 patients respectively (P < 0.001). Diagnostic confidence was high or very high in 98.3 per cent of patients for gadoxetic acid-enhanced MRI, 85.7 per cent for ECCM-MRI and 65.2 per cent for CE-CT. Surgical plans were changed during surgery in 28, 32 and 47 per cent of patients in the respective groups.
CONCLUSION: The diagnostic performance of gadoxetic acid-enhanced MRI was better than that of CE-CT and ECCM-MRI as the initial imaging modality. No further imaging was needed in the gadoxetic acid-enhanced MRI group and comparison of diagnostic efficacy parameters demonstrated the diagnostic superiority of gadoxetic acid-enhanced MRI.

Individualized IMRT treatment approach for cervical lymph node metastases of unknown primary.
Strahlenther Onkol. 2014; 190(4):386-93 [PubMed] Related Publications
PURPOSE: The goal of the present study was to evaluate the outcome of risk-adapted planning treatment volumes (PTVs) in patients with cervical lymph node metastases of unknown primary cancer (UPC) treated with intensity-modulated radiotherapy (IMRT).
PATIENTS AND MATERIAL: Between January 2006 and November 2012, 28 patients with cervical lymph node metastases of UPC were treated in our institution with IMRT either postoperatively (n = 20) or as definitive treatment (n = 8). Nodal involvement distributed as follows: N1 (n = 2), N2a (8), N2b (10), N2c (4), and N3 (4). Systemic therapy with cisplatin or cetuximab was added concomitantly in 20 of 28 patients (71 %). Radiotherapy using simultaneously integrated boost (SIB-IMRT) was carried out with 2.0 or 2.11 Gy single doses up to 66/70 Gy.
RESULTS: Mean/median follow-up was 31.6/30.5 months (range 3-78 months). In all, 15 of 28 patients were treated with unilateral SIB-IMRT (54 %). An elective PTV to the contralateral oropharynx and contralateral level II-III lymph nodes was carried out in 8 patients with PET-CT suspected but not histologically proven involvement, recurrences or former tumor of the oropharynx. More extended treatment fields were reserved for patients with N2c or bilaterally N3 status (n = 5). The 3-year overall survival, mucosal control, neck control and distant metastasis-free survival rates were 76, 100, 93, and 88 %, respectively. No patient suffered from a locoregional recurrence. Two patients treated with radiotherapy alone had persistent nodal disease. No grade II or higher late sequel has been observed.
CONCLUSION: Our single center approach to treat patients with cervical lymph node metastases of UPC with individualized, risk-adapted SIB-IMRT resulted in high locoregional tumor control and was well tolerated.

Bevacizumab combined with chemotherapy for platinum-resistant recurrent ovarian cancer: The AURELIA open-label randomized phase III trial.
J Clin Oncol. 2014; 32(13):1302-8 [PubMed] Related Publications
PURPOSE: In platinum-resistant ovarian cancer (OC), single-agent chemotherapy is standard. Bevacizumab is active alone and in combination. AURELIA is the first randomized phase III trial to our knowledge combining bevacizumab with chemotherapy in platinum-resistant OC.
PATIENTS AND METHODS: Eligible patients had measurable/assessable OC that had progressed < 6 months after completing platinum-based therapy. Patients with refractory disease, history of bowel obstruction, or > two prior anticancer regimens were ineligible. After investigators selected chemotherapy (pegylated liposomal doxorubicin, weekly paclitaxel, or topotecan), patients were randomly assigned to single-agent chemotherapy alone or with bevacizumab (10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) until progression, unacceptable toxicity, or consent withdrawal. Crossover to single-agent bevacizumab was permitted after progression with chemotherapy alone. The primary end point was progression-free survival (PFS) by RECIST. Secondary end points included objective response rate (ORR), overall survival (OS), safety, and patient-reported outcomes.
RESULTS: The PFS hazard ratio (HR) after PFS events in 301 of 361 patients was 0.48 (95% CI, 0.38 to 0.60; unstratified log-rank P < .001). Median PFS was 3.4 months with chemotherapy alone versus 6.7 months with bevacizumab-containing therapy. RECIST ORR was 11.8% versus 27.3%, respectively (P = .001). The OS HR was 0.85 (95% CI, 0.66 to 1.08; P < .174; median OS, 13.3 v 16.6 months, respectively). Grade ≥ 2 hypertension and proteinuria were more common with bevacizumab. GI perforation occurred in 2.2% of bevacizumab-treated patients.
CONCLUSION: Adding bevacizumab to chemotherapy statistically significantly improved PFS and ORR; the OS trend was not significant. No new safety signals were observed.

Vemurafenib in patients with BRAF(V600) mutated metastatic melanoma: an open-label, multicentre, safety study.
Lancet Oncol. 2014; 15(4):436-44 [PubMed] Related Publications
BACKGROUND: The orally available BRAF kinase inhibitor vemurafenib, compared with dacarbazine, shows improved response rates, progression-free survival (PFS), and overall survival in patients with metastatic melanoma that has a BRAF(V600) mutation. We assessed vemurafenib in patients with advanced metastatic melanoma with BRAF(V600) mutations who had few treatment options.
METHODS: In an open-label, multicentre study, patients with untreated or previously treated melanoma and a BRAF(V600) mutation received oral vemurafenib 960 mg twice a day. The primary endpoint was safety. All analyses were done on the safety population, which included all patients who received at least one dose of vemurafenib. This report is the third interim analysis of this study. This study is registered with ClinicalTrials.gov, number NCT01307397.
FINDINGS: Between March 1, 2011, and Jan 31, 2013, 3226 patients were enrolled in 44 countries. 3222 patients received at least one dose of vemurafenib (safety population). At data cutoff, 868 (27%) patients were on study treatment and 2354 (73%) had withdrawn, mainly because of disease progression. Common adverse events of all grades included rash (1592 [49%]), arthralgia (1259 [39%]), fatigue (1093 [34%]), photosensitivity reaction (994 [31%]), alopecia (826 [26%]), and nausea (628 [19%]). 1480 (46%) patients reported grade 3 or 4 adverse events, including cutaneous squamous cell carcinoma (389 [12%]), rash (155 [5%]), liver function abnormalities (165 [5%]), arthralgia (106 [3%]), and fatigue (93 [3%]). Grade 3 and 4 adverse events were reported more frequently in patients aged 75 years and older (n=257; 152 [59%, 95% CI 53-65] and ten [4%, 2-7], respectively) than in those younger than 75 years (n=2965; 1286 [43%, 42-45] and 82 [3%, 2-3], respectively).
INTERPRETATION: Vemurafenib safety in this diverse population of patients with BRAF(V600) mutated metastatic melanoma, who are more representative of routine clinical practice, was consistent with the safety profile shown in the pivotal trials of this drug.

Dovitinib versus sorafenib for third-line targeted treatment of patients with metastatic renal cell carcinoma: an open-label, randomised phase 3 trial.
Lancet Oncol. 2014; 15(3):286-96 [PubMed] Related Publications
BACKGROUND: An unmet medical need exists for patients with metastatic renal cell carcinoma who have progressed on VEGF-targeted and mTOR-inhibitor therapies. Fibroblast growth factor (FGF) pathway activation has been proposed as a mechanism of escape from VEGF-targeted therapies. Dovitinib is an oral tyrosine-kinase inhibitor that inhibits VEGF and FGF receptors. We therefore compared dovitinib with sorafenib as third-line targeted therapies in patients with metastatic renal cell carcinoma.
METHODS: In this multicentre phase 3 study, patients with clear cell metastatic renal cell carcinoma who received one previous VEGF-targeted therapy and one previous mTOR inhibitor were randomly assigned through an interactive voice and web response system to receive open-label dovitinib (500 mg orally according to a 5-days-on and 2-days-off schedule) or sorafenib (400 mg orally twice daily) in a 1:1 ratio. Randomisation was stratified by risk group and region. The primary endpoint was progression-free survival (PFS) assessed by masked central review. Efficacy was assessed in all patients who were randomly assigned and safety was assessed in patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT01223027.
FINDINGS: 284 patients were randomly assigned to the dovitinib group and 286 to the sorafenib group. Median follow-up was 11·3 months (IQR 7·9-14·6). Median PFS was 3·7 months (95% CI 3·5-3·9) in the dovitinib group and 3·6 months (3·5-3·7) in the sorafenib group (hazard ratio 0·86, 95% CI 0·72-1·04; one-sided p=0·063). 280 patients in the dovitinib group and 284 in the sorafenib group received at least one dose of study drug. Common grade 3 or 4 adverse events included hypertriglyceridaemia (38 [14%]), fatigue (28 [10%]), hypertension (22 [8%]), and diarrhoea (20 [7%]) in the dovitinib group, and hypertension (47 [17%]), fatigue (24 [8%]), dyspnoea (21 [7%]), and palmar-plantar erythrodysaesthesia (18 [6%]) in the sorafenib group. The most common serious adverse event was dyspnoea (16 [6%] and 15 [5%] in the dovitinib and sorafenib groups, respectively).
INTERPRETATION: Dovitinib showed activity, but this was no better than that of sorafenib in patients with renal cell carcinoma who had progressed on previous VEGF-targeted therapies and mTOR inhibitors. This trial provides reference outcome data for future studies of targeted inhibitors in the third-line setting.

Bevacizumab plus radiotherapy-temozolomide for newly diagnosed glioblastoma.
N Engl J Med. 2014; 370(8):709-22 [PubMed] Related Publications
BACKGROUND: Standard therapy for newly diagnosed glioblastoma is radiotherapy plus temozolomide. In this phase 3 study, we evaluated the effect of the addition of bevacizumab to radiotherapy-temozolomide for the treatment of newly diagnosed glioblastoma.
METHODS: We randomly assigned patients with supratentorial glioblastoma to receive intravenous bevacizumab (10 mg per kilogram of body weight every 2 weeks) or placebo, plus radiotherapy (2 Gy 5 days a week; maximum, 60 Gy) and oral temozolomide (75 mg per square meter of body-surface area per day) for 6 weeks. After a 28-day treatment break, maintenance bevacizumab (10 mg per kilogram intravenously every 2 weeks) or placebo, plus temozolomide (150 to 200 mg per square meter per day for 5 days), was continued for six 4-week cycles, followed by bevacizumab monotherapy (15 mg per kilogram intravenously every 3 weeks) or placebo until the disease progressed or unacceptable toxic effects developed. The coprimary end points were investigator-assessed progression-free survival and overall survival.
RESULTS: A total of 458 patients were assigned to the bevacizumab group, and 463 patients to the placebo group. The median progression-free survival was longer in the bevacizumab group than in the placebo group (10.6 months vs. 6.2 months; stratified hazard ratio for progression or death, 0.64; 95% confidence interval [CI], 0.55 to 0.74; P<0.001). The benefit with respect to progression-free survival was observed across subgroups. Overall survival did not differ significantly between groups (stratified hazard ratio for death, 0.88; 95% CI, 0.76 to 1.02; P=0.10). The respective overall survival rates with bevacizumab and placebo were 72.4% and 66.3% at 1 year (P=0.049) and 33.9% and 30.1% at 2 years (P=0.24). Baseline health-related quality of life and performance status were maintained longer in the bevacizumab group, and the glucocorticoid requirement was lower. More patients in the bevacizumab group than in the placebo group had grade 3 or higher adverse events (66.8% vs. 51.3%) and grade 3 or higher adverse events often associated with bevacizumab (32.5% vs. 15.8%).
CONCLUSIONS: The addition of bevacizumab to radiotherapy-temozolomide did not improve survival in patients with glioblastoma. Improved progression-free survival and maintenance of baseline quality of life and performance status were observed with bevacizumab; however, the rate of adverse events was higher with bevacizumab than with placebo.

Event-free survival at 24 months is a robust end point for disease-related outcome in diffuse large B-cell lymphoma treated with immunochemotherapy.
J Clin Oncol. 2014; 32(10):1066-73 [PubMed] Article available free on PMC after 01/04/2015 Related Publications
PURPOSE: Studies of diffuse large B-cell lymphoma (DLBCL) are typically evaluated by using a time-to-event approach with relapse, re-treatment, and death commonly used as the events. We evaluated the timing and type of events in newly diagnosed DLBCL and compared patient outcome with reference population data.
PATIENTS AND METHODS: Patients with newly diagnosed DLBCL treated with immunochemotherapy were prospectively enrolled onto the University of Iowa/Mayo Clinic Specialized Program of Research Excellence Molecular Epidemiology Resource (MER) and the North Central Cancer Treatment Group NCCTG-N0489 clinical trial from 2002 to 2009. Patient outcomes were evaluated at diagnosis and in the subsets of patients achieving event-free status at 12 months (EFS12) and 24 months (EFS24) from diagnosis. Overall survival was compared with age- and sex-matched population data. Results were replicated in an external validation cohort from the Groupe d'Etude des Lymphomes de l'Adulte (GELA) Lymphome Non Hodgkinien 2003 (LNH2003) program and a registry based in Lyon, France.
RESULTS: In all, 767 patients with newly diagnosed DLBCL who had a median age of 63 years were enrolled onto the MER and NCCTG studies. At a median follow-up of 60 months (range, 8 to 116 months), 299 patients had an event and 210 patients had died. Patients achieving EFS24 had an overall survival equivalent to that of the age- and sex-matched general population (standardized mortality ratio [SMR], 1.18; P = .25). This result was confirmed in 820 patients from the GELA study and registry in Lyon (SMR, 1.09; P = .71). Simulation studies showed that EFS24 has comparable power to continuous EFS when evaluating clinical trials in DLBCL.
CONCLUSION: Patients with DLBCL who achieve EFS24 have a subsequent overall survival equivalent to that of the age- and sex-matched general population. EFS24 will be useful in patient counseling and should be considered as an end point for future studies of newly diagnosed DLBCL.

Pharmacokinetics and safety of subcutaneous rituximab in follicular lymphoma (SABRINA): stage 1 analysis of a randomised phase 3 study.
Lancet Oncol. 2014; 15(3):343-52 [PubMed] Related Publications
BACKGROUND: Intravenous rituximab is a mainstay of treatment for follicular lymphoma. A subcutaneous formulation that achieves equivalent rituximab serum concentrations might improve convenience and save health-care resources without sacrificing clinical activity. We aimed to assess pharmacokinetic non-inferiority of 3 week cycles of fixed-dose subcutaneous rituximab versus standard intravenous rituximab.
METHODS: In our two-stage, randomised, open-label, phase 3 trial, we enrolled patients with previously untreated grade 1-3a, CD20-positive follicular lymphoma at 67 centres in 23 countries. In stage 1, we randomly allocated patients 1:1 with the Pocock and Simon algorithm to intravenous rituximab (375 mg/m(2)) or fixed-dose subcutaneous rituximab (1400 mg), stratified by induction chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine, prednisone or cyclophosphamide, vincristine, prednisone), Follicular Lymphoma International Prognostic Index score, and region. After randomisation, patients received one induction dose of intravenous rituximab in cycle 1 and then allocated treatment for cycles 2-8. Patients with a complete or partial response following induction therapy continued intravenous or subcutaneous rituximab as maintenance every 8 weeks. The primary endpoint was the ratio of observed rituximab serum trough concentrations (Ctrough) between groups at cycle 7 (before cycle 8 dosing) of induction treatment in a per-protocol population. Patients were analysed as treated for safety endpoints. Stage 2 follow-up is ongoing and is fully accrued. This study is registered with ClinicalTrials.gov, number NCT01200758.
FINDINGS: Between Feb 4, 2010, and Oct 21, 2011, we enrolled 127 patients. Pharmacokinetic data were available for 48 (75%) of 64 patients randomly allocated intravenous rituximab and 54 (86%) of 63 patients randomly allocated subcutaneous rituximab. Geometric mean Ctrough was 83·13 μg/mL in the intravenous group and 134·58 μg/mL in the subcutaneous group (ratio 1·62, 90% CI 1·36-1·94), showing non-inferiority of subcutaneous rituximab. 57 (88%) of 65 patients in the intravenous rituximab safety population had adverse events (30 [46%] grade ≥3), as did 57 (92%) of 62 patients in the subcutaneous rituximab safety population (29 [47%] grade ≥3). The most common grade 3 or worse adverse event in both groups was neutropenia (14 [22%] patients in the intravenous group and 16 [26%] patients in the subcutaneous group). Adverse events related to administration were mostly grade 1-2 and occurred in 21 (32%) patients in the intravenous group and 31 (50%) patients in the subcutaneous group.
INTERPRETATION: Stage 1 data show that the pharmacokinetic profile of subcutaneous rituximab was non-inferior to intravenous rituximab and was not associated with new safety concerns. Stage 2 will provide data for efficacy and safety of the subcutaneous administration.

Safety and efficacy of vemurafenib in BRAF(V600E) and BRAF(V600K) mutation-positive melanoma (BRIM-3): extended follow-up of a phase 3, randomised, open-label study.
Lancet Oncol. 2014; 15(3):323-32 [PubMed] Related Publications
BACKGROUND: In the BRIM-3 trial, vemurafenib was associated with risk reduction versus dacarbazine of both death and progression in patients with advanced BRAF(V600) mutation-positive melanoma. We present an extended follow-up analysis of the total population and in the BRAF(V600E) and BRAF(V600K) mutation subgroups.
METHODS: Patients older than 18 years, with treatment-naive metastatic melanoma and whose tumour tissue was positive for BRAF(V600) mutations were eligible. Patients also had to have a life expectancy of at least 3 months, an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and adequate haematological, hepatic, and renal function. Patients were randomly assigned by interactive voice recognition system to receive either vemurafenib (960 mg orally twice daily) or dacarbazine (1000 mg/m(2) of body surface area intravenously every 3 weeks). Coprimary endpoints were overall survival and progression-free survival, analysed in the intention-to-treat population (n=675), with data censored at crossover. A sensitivity analysis was done. This trial is registered with ClinicalTrials.gov, NCT01006980.
FINDINGS: 675 eligible patients were enrolled from 104 centres in 12 countries between Jan 4, 2010, and Dec 16, 2010. 337 patients were randomly assigned to receive vemurafenib and 338 to receive dacarbazine. Median follow-up was 12·5 months (IQR 7·7-16·0) on vemurafenib and 9·5 months (3·1-14·7) on dacarbazine. 83 (25%) of the 338 patients initially randomly assigned to dacarbazine crossed over from dacarbazine to vemurafenib. Median overall survival was significantly longer in the vemurafenib group than in the dacarbazine group (13·6 months [95% CI 12·0-15·2] vs 9·7 months [7·9-12·8]; hazard ratio [HR] 0·70 [95% CI 0·57-0·87]; p=0·0008), as was median progression-free survival (6·9 months [95% CI 6·1-7·0] vs 1·6 months [1·6-2·1]; HR 0·38 [95% CI 0·32-0·46]; p<0·0001). For the 598 (91%) patients with BRAF(V600E) disease, median overall survival in the vemurafenib group was 13·3 months (95% CI 11·9-14·9) compared with 10·0 months (8·0-14·0) in the dacarbazine group (HR 0·75 [95% CI 0·60-0·93]; p=0·0085); median progression-free survival was 6·9 months (95% CI 6·2-7·0) and 1·6 months (1·6-2·1), respectively (HR 0·39 [95% CI 0·33-0·47]; p<0·0001). For the 57 (9%) patients with BRAF(V600K) disease, median overall survival in the vemurafenib group was 14·5 months (95% CI 11·2-not estimable) compared with 7·6 months (6·1-16·6) in the dacarbazine group (HR 0·43 [95% CI 0·21-0·90]; p=0·024); median progression-free survival was 5·9 months (95% CI 4·4-9·0) and 1·7 months (1·4-2·9), respectively (HR 0·30 [95% CI 0·16-0·56]; p<0·0001). The most frequent grade 3-4 events were cutaneous squamous-cell carcinoma (65 [19%] of 337 patients) and keratoacanthomas (34 [10%]), rash (30 [9%]), and abnormal liver function tests (38 [11%]) in the vemurafenib group and neutropenia (26 [9%] of 287 patients) in the dacarbazine group. Eight (2%) patients in the vemurafenib group and seven (2%) in the dacarbazine group had grade 5 events.
INTERPRETATION: Inhibition of BRAF with vemurafenib improves survival in patients with the most common BRAF(V600E) mutation and in patients with the less common BRAF(V600K) mutation.

Crizotinib in advanced, chemoresistant anaplastic lymphoma kinase-positive lymphoma patients.
J Natl Cancer Inst. 2014; 106(2):djt378 [PubMed] Related Publications
Anaplastic lymphoma kinase (ALK)-positive lymphomas respond to chemotherapy, but relapses, which bear a poor prognosis, occur. Crizotinib inhibits ALK in vitro and in vivo and was administered as monotherapy to 11 ALK+ lymphoma patients who were resistant/refractory to cytotoxic therapy. The overall response rate was 10 of 11 (90.9%; 95% confidence interval [CI] = 58.7% to 99.8%). Disease status at the latest follow-up is as follows: four patients are in complete response (CR) (months >21, >30, >35, >40) under continuous crizotinib administration; 4 patients had progression of disease (months 1, 2, 2, 2); 1 patient obtained CR on crizotinib, received an allogeneic bone marrow transplant, and is in CR; 2 patients (treated before and/or after allogeneic bone marrow transplant) obtained and are still in CR but they have stopped crizotinib. Overall and progression-free survival rates at 2 years are 72.7% (95% CI = 39.1% to 94.0%) and 63.7% (95% CI = 30.8% to 89.1%), respectively. ALK mutations conferring resistance to crizotinib in vitro could be identified in relapsed patients. Crizotinib exerted a potent antitumor activity with durable responses in advanced, heavily pretreated ALK+ lymphoma patients, with a benign safety profile.

Fluorouracil-based adjuvant chemotherapy after preoperative chemoradiotherapy in rectal cancer: long-term results of the EORTC 22921 randomised study.
Lancet Oncol. 2014; 15(2):184-90 [PubMed] Related Publications
BACKGROUND: EORTC trial 22921 examined the addition of preoperative or postoperative chemotherapy to preoperative radiotherapy in patients with rectal cancer. After a median follow-up of 5 years, chemotherapy-irrespective of timing-significantly improved local control. Adjuvant chemotherapy did not improve survival, but the Kaplan-Meier curves diverged, suggesting possible delayed benefit. Here, we report the updated long-term results.
METHODS: We randomly assigned patients with clinical stage T3 or T4 resectable rectal cancer to receive preoperative radiotherapy with or without concomitant chemotherapy before surgery followed by either adjuvant chemotherapy or surveillance. Randomisation was done using minimisation with factors of institution, sex, T stage, and distance from the tumour to the anal verge. Study coordinators, clinicians, and patients were aware of assignment. Radiotherapy consisted of 45 Gy to the posterior pelvis in 25 fractions of 1·8 Gy over 5 weeks. Each course of chemotherapy consisted of fluorouracil (350 mg/m(2) per day intravenous bolus) and folinic acid (leucovorin; 20 mg/m(2) per day intravenous bolus). For preoperative chemotherapy, two courses were given (during weeks 1 and 5 of radiotherapy). Adjuvant chemotherapy was given in four cycles, every 3 weeks. The primary endpoint was overall survival. This analysis was done by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT00002523.
FINDINGS: 1011 patients were randomly assigned to treatment between April, 1993, and March, 2003 (252 to preoperative radiotherapy and 253 to each of the other three groups). After a median follow-up of 10·4 years (IQR 7·8-13·1), 10-year overall survival was 49·4% (95% CI 44·6-54·1) for the preoperative radiotherapy group and 50·7% (45·9-55·2) for the preoperative radiotherapy and chemotherapy group (HR 0·99, 95% CI 0·83-1·18; p=0·91). 10-year overall survival was 51·8% (95% CI 47·0-56·4) for the adjuvant chemotherapy group and 48·4% (43·6-53·0) for the surveillance group (HR 0·91, 95% CI 0·77-1·09, p=0·32). 10-year disease-free survival was 44·2% (95% CI 39·5-48·8) for the preoperative radiotherapy group and 46·4% (41·7-50·9) for the preoperative radiotherapy and chemotherapy group (HR 0·93, 95% CI 0·79-1·10; p=0·38). 10-year disease-free survival was 47·0% (95% CI 42·2-51·6) for the adjuvant chemotherapy group and 43·7% (39·1-48·2) for the surveillance group (HR 0·91, 95% CI 0·77-1·08, p=0·29). At 10 years, cumulative incidence of local relapse was 22·4% (95% CI 17·1-27·6) with radiotherapy alone, 11·8% (7·8-15·8) with neoadjuvant radiotherapy and chemotherapy, 14·5% (10·1-18·9) with radiotherapy and adjuvant chemotherapy and 11·7% (7·7-15·6) with both adjuvant and neoadjuvant chemotherapy (p=0·0017). There was no difference in cumulative incidence of distant metastases (p=0·52). The frequency of long-term side-effects did not differ between the four groups (p=0·22).
INTERPRETATION: Adjuvant fluorouracil-based chemotherapy after preoperative radiotherapy (with or without chemotherapy) does not affect disease-free survival or overall survival. Our trial does not support the current practice of adjuvant chemotherapy after preoperative radiotherapy with or without chemotherapy. New treatment strategies incorporating neoadjuvant chemotherapy are required.

Chemotherapy for isolated locoregional recurrence of breast cancer (CALOR): a randomised trial.
Lancet Oncol. 2014; 15(2):156-63 [PubMed] Article available free on PMC after 01/02/2015 Related Publications
BACKGROUND: Patients with isolated locoregional recurrences (ILRR) of breast cancer have a high risk of distant metastasis and death from breast cancer. We aimed to establish whether adjuvant chemotherapy improves the outcome of such patients.
METHODS: The CALOR trial was a pragmatic, open-label, randomised trial that accrued patients with histologically proven and completely excised ILRR after unilateral breast cancer who had undergone a mastectomy or lumpectomy with clear surgical margins. Eligible patients were enrolled from hospitals worldwide and were centrally randomised (1:1) to chemotherapy (type selected by the investigator; multidrug for at least four courses recommended) or no chemotherapy, using permuted blocks, and stratified by previous chemotherapy, oestrogen-receptor and progesterone-receptor status, and location of ILRR. Patients with oestrogen-receptor-positive ILRR received adjuvant endocrine therapy, radiation therapy was mandated for patients with microscopically involved surgical margins, and anti-HER2 therapy was optional. The primary endpoint was disease-free survival. All analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00074152.
FINDINGS: From Aug 22, 2003, to Jan 31, 2010, 85 patients were randomly assigned to receive chemotherapy and 77 were assigned to no chemotherapy. At a median follow-up of 4·9 years (IQR 3·6-6 ·0), 24 (28%) patients had disease-free survival events in the chemotherapy group compared with 34 (44%) in the no chemotherapy group. 5-year disease-free survival was 69% (95% CI 56-79) with chemotherapy versus 57% (44-67) without chemotherapy (hazard ratio 0·59 [95% CI 0·35-0·99]; p=0·046). Adjuvant chemotherapy was significantly more effective for women with oestrogen-receptor-negative ILRR (pinteraction=0·046), but analyses of disease-free survival according to the oestrogen-receptor status of the primary tumour were not statistically significant (pinteraction=0·43). Of the 81 patients who received chemotherapy, 12 (15%) had serious adverse events. The most common adverse events were neutropenia, febrile neutropenia, and intestinal infection.
INTERPRETATION: Adjuvant chemotherapy should be recommended for patients with completely resected ILRR of breast cancer, especially if the recurrence is oestrogen-receptor negative.

11C-choline PET/CT predicts prostate cancer-specific survival in patients with biochemical failure during androgen-deprivation therapy.
J Nucl Med. 2014; 55(2):233-41 [PubMed] Related Publications
UNLABELLED: Several studies have shown that (11)C-choline PET/CT may be useful for restaging prostate cancer (PCa) patients with biochemical failure after radical prostatectomy. However, validation of (11)C-choline PET/CT findings scarcely relied on histologic findings, and prognostic implications of (11)C-choline PET/CT are currently unknown. The aim of this study was to assess whether (11)C-choline PET/CT predicts survival in PCa patients.
METHODS: This retrospective study included 195 PCa patients treated with radical prostatectomy who underwent (11)C-choline PET/CT from December 1, 2004, to July 31, 2007, due to biochemical failure (prostate-specific antigen > 0.2 mg/mL) during androgen-deprivation therapy. PCa-specific survival was computed as the interval from radical prostatectomy to PCa-specific death.
RESULTS: The median interval after radical prostatectomy was 8.9 y (95% confidence interval [CI], 1.7-18.9 y). The median follow-up after (11)C-choline PET/CT was 4.5 y (95% CI, 0.4-8.5 y). (11)C-choline PET/CT results were positive in 57% of patients. The median PCa-specific survival was 16.4 y (95% CI, 14.0-18.8 y) in patients with negative (11)C-choline PET/CT results and 11.2 y (95% CI, 9.8-12.6 y) in patients with positive (11)C-choline PET/CT results (log-rank: χ(2) = 19.3, P < 0001). At multivariate analysis, statistical significance was obtained for (11)C-choline PET/CT (hazard ratio, 2.53; 95% CI, 1.41-4.53; P = 0.002), prostate-specific antigen (hazard ratio, 1.03; 95% CI, 1.00-1.05; P = 0.037), and Gleason score (>7: hazard ratio, 2.49; 95% CI, 1.25-4.95; P = 0.009). Patients with pathologic (11)C-choline uptake in the prostatic bed or in pelvic or retroperitoneal lymph nodes had longer PCa-specific survival (median, 12.1 y; 95% CI, 10.5-13.7 y) in comparison to patients with pathologic tracer uptake in the skeleton (median, 9.9 y; 95% CI, 6.8-13.1 y) (log-rank: χ(2) = 6.5, P = 0.010). Two internally validated nomograms predicted 10- and 15-y PCa-specific survival probability with an accuracy of 76% and 74%, respectively. In an ancillary analysis, we also showed that (11)C-choline PET/CT predicts PCa-specific survival after PET/CT, with similar statistical power.
CONCLUSION: (11)C-choline PET/CT predicts PCa-specific survival in PCa patients treated with radical prostatectomy who develop biochemical failure during androgen-deprivation therapy. If independent or multicenter confirmation of these findings is obtained, (11)C-choline PET/CT might be more widely used in the follow-up of PCa patients for tailoring salvage therapy.

Obinutuzumab plus chlorambucil in patients with CLL and coexisting conditions.
N Engl J Med. 2014; 370(12):1101-10 [PubMed] Related Publications
BACKGROUND: The monoclonal anti-CD20 antibody rituximab, combined with chemotherapeutic agents, has been shown to prolong overall survival in physically fit patients with previously untreated chronic lymphocytic leukemia (CLL) but not in those with coexisting conditions. We investigated the benefit of the type 2, glycoengineered antibody obinutuzumab (also known as GA101) as compared with that of rituximab, each combined with chlorambucil, in patients with previously untreated CLL and coexisting conditions.
METHODS: We randomly assigned 781 patients with previously untreated CLL and a score higher than 6 on the Cumulative Illness Rating Scale (CIRS) (range, 0 to 56, with higher scores indicating worse health status) or an estimated creatinine clearance of 30 to 69 ml per minute to receive chlorambucil, obinutuzumab plus chlorambucil, or rituximab plus chlorambucil. The primary end point was investigator-assessed progression-free survival.
RESULTS: The patients had a median age of 73 years, creatinine clearance of 62 ml per minute, and CIRS score of 8 at baseline. Treatment with obinutuzumab-chlorambucil or rituximab-chlorambucil, as compared with chlorambucil monotherapy, increased response rates and prolonged progression-free survival (median progression-free survival, 26.7 months with obinutuzumab-chlorambucil vs. 11.1 months with chlorambucil alone; hazard ratio for progression or death, 0.18; 95% confidence interval [CI], 0.13 to 0.24; P<0.001; and 16.3 months with rituximab-chlorambucil vs. 11.1 months with chlorambucil alone; hazard ratio, 0.44; 95% CI, 0.34 to 0.57; P<0.001). Treatment with obinutuzumab-chlorambucil, as compared with chlorambucil alone, prolonged overall survival (hazard ratio for death, 0.41; 95% CI, 0.23 to 0.74; P=0.002). Treatment with obinutuzumab-chlorambucil, as compared with rituximab-chlorambucil, resulted in prolongation of progression-free survival (hazard ratio, 0.39; 95% CI, 0.31 to 0.49; P<0.001) and higher rates of complete response (20.7% vs. 7.0%) and molecular response. Infusion-related reactions and neutropenia were more common with obinutuzumab-chlorambucil than with rituximab-chlorambucil, but the risk of infection was not increased.
CONCLUSIONS: Combining an anti-CD20 antibody with chemotherapy improved outcomes in patients with CLL and coexisting conditions. In this patient population, obinutuzumab was superior to rituximab when each was combined with chlorambucil. (Funded by F. Hoffmann-La Roche; ClinicalTrials.gov number, NCT01010061.).

PD-1 and Tim-3 regulate the expansion of tumor antigen-specific CD8⁺ T cells induced by melanoma vaccines.
Cancer Res. 2014; 74(4):1045-55 [PubMed] Article available free on PMC after 15/02/2015 Related Publications
Although melanoma vaccines stimulate tumor antigen-specific CD8(+) T cells, objective clinical responses are rarely observed. To investigate this discrepancy, we evaluated the character of vaccine-induced CD8(+) T cells with regard to the inhibitory T-cell coreceptors PD-1 and Tim-3 in patients with metastatic melanoma who were administered tumor vaccines. The vaccines included incomplete Freund's adjuvant, CpG oligodeoxynucleotide (CpG), and the HLA-A2-restricted analog peptide NY-ESO-1 157-165V, either by itself or in combination with the pan-DR epitope NY-ESO-1 119-143. Both vaccines stimulated rapid tumor antigen-specific CD8(+) T-cell responses detected ex vivo, however, tumor antigen-specific CD8(+) T cells produced more IFN-γ and exhibited higher lytic function upon immunization with MHC class I and class II epitopes. Notably, the vast majority of vaccine-induced CD8(+) T cells upregulated PD-1 and a minority also upregulated Tim-3. Levels of PD-1 and Tim-3 expression by vaccine-induced CD8(+) T cells at the time of vaccine administration correlated inversely with their expansion in vivo. Dual blockade of PD-1 and Tim-3 enhanced the expansion and cytokine production of vaccine-induced CD8(+) T cells in vitro. Collectively, our findings support the use of PD-1 and Tim-3 blockades with cancer vaccines to stimulate potent antitumor T-cell responses and increase the likelihood of clinical responses in patients with advanced melanoma.

Impact of ABO blood type on outcomes in patients with primary nonmuscle invasive bladder cancer.
J Urol. 2014; 191(5):1238-43 [PubMed] Related Publications
PURPOSE: ABO blood type is an established prognostic factor for several malignancies but its role in bladder urothelial carcinoma is largely unknown. We determined whether ABO blood type is associated with the outcome of transurethral resection of nonmuscle invasive bladder urothelial carcinoma.
MATERIALS AND METHODS: We retrospectively studied ABO blood types in 931 patients with primary nonmuscle invasive bladder urothelial carcinoma treated with transurethral bladder resection with or without intravesical instillation therapy. Disease recurrence and progression were analyzed with univariable and multivariable competing risks regression models. Median followup was 67 months. Discrimination was evaluated by the concordance index.
RESULTS: The ABO blood type was O, A, B and AB in 414 (44.5%), 360 (38.7%), 103 (11.1%) and 54 patients (5.8%), respectively. ABO blood type was significantly associated with outcome on univariable and multivariable analysis. Overall, patients with blood type O had worse recurrence and progression rates than those with A (p = 0.015 and 0.031) or B (p = 0.004 and 0.075, respectively). The concordance index of multivariable base models increased after including ABO blood type.
CONCLUSIONS: In patients with nonmuscle invasive bladder urothelial carcinoma the ABO blood type may predict the outcome. Those with blood type O showed the highest recurrence and progression rates. Including ABO blood type in multivariable models increases the accuracy of standard prognostic factors. Since the ABO blood type is available for most patients, it may represent an ideal adjunctive marker to predict recurrence and progression. The biological explanation and prognostic value of this finding must be further elucidated.

Deep molecular response is reached by the majority of patients treated with imatinib, predicts survival, and is achieved more quickly by optimized high-dose imatinib: results from the randomized CML-study IV.
J Clin Oncol. 2014; 32(5):415-23 [PubMed] Related Publications
PURPOSE: Deep molecular response (MR(4.5)) defines a subgroup of patients with chronic myeloid leukemia (CML) who may stay in unmaintained remission after treatment discontinuation. It is unclear how many patients achieve MR(4.5) under different treatment modalities and whether MR(4.5) predicts survival.
PATIENTS AND METHODS: Patients from the randomized CML-Study IV were analyzed for confirmed MR(4.5) which was defined as ≥ 4.5 log reduction of BCR-ABL on the international scale (IS) and determined by reverse transcriptase polymerase chain reaction in two consecutive analyses. Landmark analyses were performed to assess the impact of MR(4.5) on survival.
RESULTS: Of 1,551 randomly assigned patients, 1,524 were assessable. After a median observation time of 67.5 months, 5-year overall survival (OS) was 90%, 5-year progression-free-survival was 87.5%, and 8-year OS was 86%. The cumulative incidence of MR(4.5) after 9 years was 70% (median, 4.9 years); confirmed MR(4.5) was 54%. MR(4.5) was reached more quickly with optimized high-dose imatinib than with imatinib 400 mg/day (P = .016). Independent of treatment approach, confirmed MR(4.5) at 4 years predicted significantly higher survival probabilities than 0.1% to 1% IS, which corresponds to complete cytogenetic remission (8-year OS, 92% v 83%; P = .047). High-dose imatinib and early major molecular remission predicted MR(4.5). No patient with confirmed MR(4.5) has experienced progression.
CONCLUSION: MR(4.5) is a new molecular predictor of long-term outcome, is reached by a majority of patients treated with imatinib, and is achieved more quickly with optimized high-dose imatinib, which may provide an improved therapeutic basis for treatment discontinuation in CML.

METHODS: This open-label trial assessed vemurafenib (960mg twice a day) in patients with BRAF(V600) mutation-positive metastatic melanoma with non-resectable, previously treated brain metastases. The primary end-point was safety. Secondary end-points included best overall response rate, and progression-free and overall survival.
RESULTS: Twenty-four patients received vemurafenib for a median treatment duration of 3.8 (0.1-11.3) months. The majority of discontinuations were due to disease progression (n=22). Twenty-three of 24 patients reported at least one adverse event (AE). Grade 3 AEs were reported in four (17%; 95% confidence interval [CI], 4.7-37.4%) patients and included cutaneous squamous cell carcinoma in four patients. Median progression-free survival was 3.9 (95% CI, 3.0-5.5) months, and median survival was 5.3 (95% CI, 3.9-6.6) months. An overall partial response (PR) at both intracranial and extracranial sites was achieved in 10 of 24 (42%; 95% CI, 22.1-63.4) evaluable patients, with stable disease in nine (38%; 95% CI, 18.8-59.4) patients. Of 19 patients with measurable intracranial disease, seven (37%) achieved >30% intracranial tumour regression, and three (16%; 95% CI, 3.4-39.6%) achieved a confirmed PR. Other signs of improvement included reduced need for corticosteroids and enhanced performance status.
CONCLUSIONS: Vemurafenib can be safely used in patients with advanced symptomatic melanoma that has metastasised to the brain and can result in meaningful tumour regression.

Open-label, multicentre expansion cohort to evaluate imgatuzumab in pre-treated patients with KRAS-mutant advanced colorectal carcinoma.
Eur J Cancer. 2014; 50(3):496-505 [PubMed] Related Publications
AIM: Imgatuzumab (GA201) is a novel anti-epidermal growth factor receptor (anti-EGFR) antibody glycoengineered for enhanced antibody-dependent cell-mediated cytotoxicity (ADCC). We investigated the efficacy of imgatuzumab in patients with EGFR-positive, KRAS-mutant advanced colorectal cancer.
METHODS: Patients received single-agent imgatuzumab (1400mg on day 1 and 8 followed by q2W) as third line therapy in an open-label, multicentre, non-randomised, expansion study. The primary end-point was tumour response. Pre- and on-treatment biopsies and blood samples were investigated for biomarkers related to imgatuzumab's believed mechanism of action (MoA).
RESULTS: 25 patients were treated and the best overall response was stable disease occurring in 40% of patients at 8weeks, 24% at 16weeks and 8% (two patients) at 32weeks. Median overall survival was 9.3months (95% confidence interval (CI): 5.1-12.3). Treatment-related rash, hypomagnesaemia and infusion-related reactions were the most common adverse events. Comparison of pre- and post-treatment biopsies revealed that the number of tumour-infiltrating immune cells increased notably after one cycle of therapy (median compound immune reactive score of 1491 versus 898 cells/mm(3) at baseline), whereas the number of peripheral natural killer cells decreased. A potential association between baseline tumour immune infiltration and clinical efficacy was seen.
CONCLUSIONS: These data may suggest that the MoA of imgatuzumab involves ADCC-related immune effects in the tumour and is not limited to simple receptor blockade.

Specialized pathology review in patients with ovarian cancer: results from a prospective study.
Int J Gynecol Cancer. 2013; 23(8):1376-82 [PubMed] Related Publications
BACKGROUND: A significant number of ovarian borderline tumors (BOTs) and metastatic nonovarian primaries are erroneously diagnosed as ovarian carcinomas. If BOTs are misdiagnosed as cancer, patients may not only experience nonbeneficial morbidity but may have to cope with an incorrect diagnosis of cancer for the rest of their lives. In cases of metastatic disease mistaken for an ovarian primary, more adequate therapeutic modalities may be withheld from some patients. Finally, clinical trials may be biased through unintended disregard of histological inclusion criteria.
METHODS: Patients were recruited for central pathology review according to a translational subprotocol of a prospectively randomized phase 3 study led by the Arbeitsgemeinschaft Gynaekologische Onkologie (AGO) Study Group. All original slides were requested, and a specialized central pathology review was performed by experienced gynecopathologists. In cases of clinically relevant diagnostic discrepancies, the pathologist responsible for the original diagnosis was contacted. If a given discrepancy could not be resolved, a panel of experts was involved for clarification.
RESULTS: Four hundred fifty-four patients with an original diagnosis of ovarian, tubal, or peritoneal epithelial carcinoma were recruited. In 6.8% (31 patients), a major diagnostic discrepancy of clinical relevance was found. Most frequently (15 patients), serous BOT had been misdiagnosed as invasive cancer. Ovarian metastases constituted the second most frequent misdiagnosis (13 patients). Minor discrepancies not affecting patient treatment were found in 28.2% (128 patients).
CONCLUSIONS: Specialized central pathology review could help to avoid overtreatment of patients with BOT and inappropriate treatment of patients with ovarian metastases. The implementation of a specialized case review process may translate into enhanced patient safety in clinical trials of ovarian carcinomas. Furthermore, central pathology review may increase the rigor and ultimately the transferability of clinical research into practice and should therefore become a standard procedure in study protocols evaluating new therapies.

Validation of the revised international prognostic scoring system (IPSS-R) in patients with myelodysplastic syndrome: a multicenter study.
Leuk Res. 2014; 38(1):57-64 [PubMed] Related Publications
The revised IPSS (IPSS-R) was developed aiming at a better prognostication, taking into account patients treated with best supportive care. We herein validated this model on the basis of data from 1314 patients who received BSC only as well as patients who underwent induction chemotherapy (n=214) or allogeneic transplantation (n=167). We could demonstrate a clear distinction of the IPSS-R risk categories with regard to survival and risk of AML evolution in all patient cohorts. When comparing IPSS-R, IPSS, WHO prognostic scoring system (WPSS) and Duesseldorf score, the best results regarding the ability to predict survival were obtained by the IPSS-R.

Expression of somatostatin receptors, angiogenesis and proliferation markers in pituitary adenomas: an immunohistochemical study with diagnostic and therapeutic implications.
Swiss Med Wkly. 2013; 143:w13895 [PubMed] Related Publications
PRINCIPLES: Pituitary adenomas are common intracranial neoplasms that generate symptoms as a result of either mass effect or the increased production of pituitary hormones. Although mostly benign, these tumours can be associated with considerable morbidity. We investigated a panel of immunohistochemical preparations to identify potential therapeutic targets and surrogate markers of clinical outcome.
METHODS: Tumour tissue from 25 patients was evaluated for immunohistochemical expression of somatostatin receptors 1‒5, von Willebrand-factor (vWF), interleukin-8 (IL-8), vascular endothelial growth factor receptor 2 (VEGFR-2), kinesin spindle protein (Eg5) and MIB-1 (Ki-67), and its relationship with clinical features was analysed.
RESULTS: The proliferation marker MIB-1 (Ki-67) was the only marker predictive of adenoma recurrence. Of note, 67% of all relapses were associated with tumours showing luteinising hormone expression. All pituitary adenomas showed variable somatostatin receptor, IL-8, Eg5, vWF and VEGFR-2 expression; a relationship between these parameters and clinical outcome could not be demonstrated in this cohort.
CONCLUSIONS: This study validates MIB-1 (Ki-67) as a reliable marker of tumour recurrence in pituitary adenomas. Considering the consistently increased expression of Eg5, IL-8, VEGFR-2, somatostatin receptors and vWF in these tumours, further investigation as potential therapeutic targets is warranted.

Upstream mitogen-activated protein kinase (MAPK) pathway inhibition: MEK inhibitor followed by a BRAF inhibitor in advanced melanoma patients.
Eur J Cancer. 2014; 50(2):406-10 [PubMed] Related Publications
BRAF-mutant melanoma can be successfully treated by BRAF kinase inhibitors (BRAFi) and MEK kinase inhibitors (MEKi). However, the administration of BRAFi followed by MEKi did not generate promising response rate (RR). The purpose of this investigation was to evaluate the time to progression (TTP) with a mitogen-activated protein kinase (MAPK) pathway upstream inhibition strategy in BRAF mutated melanoma patients. BRAF mutation positive metastatic melanoma patients were identified within the Dermatology Cooperative Oncology Group (DeCOG) network and were treated first with a MEKi and upon progression with a selective BRAFi. A total of 23 melanoma patients (six females, 17 males, aged 47-80 years) were retrospectively analysed for TTP. The total median TTP was 8.9 months. The median TTP for MEKi was 4.8 (1.2-23.2) and subsequent for BRAFi 4.5 (1.2-15.7) months, respectively. A higher RR for MEKi (39%, nine partial responses and 0 complete responses) than previously reported was observed. Our analysis suggests that the reversed inhibition of the MAPK pathway is feasible in BRAF mutated melanoma. The median TTP (8.9 months) is close to the promising BRAF- and MEKi combination therapy (median progression-free survival (PFS) 9.4 months). The total treatment duration of the MAPK inhibition when a MEKi is administered first is similar compared to the reversed sequence, but TTP shifts in favour to the MEKi. This approach is feasible with reasonable tolerability. This clinical investigation encourages further studies in prospective clinical trials to define the optimal treatment schedule for the MAPK pathway inhibition and should be accompanied by molecular monitoring using repeated biopsies.

Toward a NOTCH1/FBXW7/RAS/PTEN-based oncogenetic risk classification of adult T-cell acute lymphoblastic leukemia: a Group for Research in Adult Acute Lymphoblastic Leukemia study.
J Clin Oncol. 2013; 31(34):4333-42 [PubMed] Related Publications
PURPOSE: The Group for Research in Adult Acute Lymphoblastic Leukemia (GRAALL) recently reported a significantly better outcome in T-cell acute lymphoblastic leukemia (T-ALL) harboring NOTCH1 and/or FBXW7 (N/F) mutations compared with unmutated T-ALL. Despite this, one third of patients with N/F-mutated T-ALL experienced relapse.
PATIENTS AND METHODS: In a series of 212 adult T-ALLs included in the multicenter randomized GRAALL-2003 and -2005 trials, we searched for additional N/K-RAS mutations and PTEN defects (mutations and gene deletion).
RESULTS: N/F mutations were identified in 143 (67%) of 212 patients, and lack of N/F mutation was confirmed to be associated with a poor prognosis. K-RAS, N-RAS, and PTEN mutations/deletions were identified in three (1.6%) of 191, 17 (8.9%) of 191, and 21 (12%) of 175 patients, respectively. The favorable prognostic significance of N/F mutations was restricted to patients without RAS/PTEN abnormalities. These observations led us to propose a new T-ALL oncogenetic classifier defining low-risk patients as those with N/F mutation but no RAS/PTEN mutation (97 of 189 patients; 51%) and all other patients (49%; including 13% with N/F and RAS/PTEN mutations) as high-risk patients. In multivariable analysis, this oncogenetic classifier remained the only significant prognostic covariate (event-free survival: hazard ratio [HR], 3.2; 95% CI, 1.9 to 5.15; P < .001; and overall survival: HR, 3.2; 95% CI, 1.9 to 5.6; P < .001).
CONCLUSION: These data demonstrate that the presence of N/F mutations in the absence of RAS or PTEN abnormalities predicts good outcome in almost 50% of adult T-ALL. Conversely, the absence of N/F or presence of RAS/PTEN alterations identifies the remaining cohort of patients with poor prognosis.

Outcomes of radical cystectomy with extended lymphadenectomy alone in patients with lymph node-positive bladder cancer who are unfit for or who decline adjuvant chemotherapy.
BJU Int. 2014; 113(4):554-60 [PubMed] Related Publications
OBJECTIVE: To analyse the long-term outcomes of patients with lymph node (LN)-positive bladder cancer, who did not receive any adjuvant therapy after radical cystectomy (RC) and extended pelvic lymph node dissection (ePLND).
PATIENTS AND METHODS: We conducted a retrospective, combined cohort analysis based on two prospectively maintained cystectomy databases from the University of Southern California and the University of Bern. Eligible patients underwent RC with ePLND for cN0M0 disease but were found to have LN-positive disease. No patient had neoadjuvant therapy, and all had negative surgical margins. Kaplan-Meier plots were used to estimate recurrence-free survival (RFS) and overall survival (OS). Subgroup comparisons were performed using log-rank tests, and multivariable analysis was based on Cox proportional hazard models.
RESULTS: Of 521 patients with LN-positive disease, 251 (48%) never received adjuvant therapy. Although the pathological stage distribution was similar, the 251 patients who did not receive adjuvant therapy were older and had both fewer total and positive LNs than those who underwent adjuvant therapy. The median RFS for patients treated with RC alone was 1.6 years. Recurrences mainly occurred <2 years after RC, resulting in 5- and 10-year RFS rates of 32 and 26%, respectively. Pathological T stage, the total number of LNs and the number of positive LNs detected were independent predictors of RFS and OS.
CONCLUSIONS: In this study, 25% of patients with documented LN metastases who did not receive adjuvant therapy were cured with RC and ePLND; however, a few relapses may occur later than 3 years. Predictors of survival were pathological T stage, the number of total LNs and the number of positive LNs identified.

Diabetes mellitus without metformin intake is associated with worse oncologic outcomes after radical nephroureterectomy for upper tract urothelial carcinoma.
Eur J Surg Oncol. 2014; 40(1):113-20 [PubMed] Related Publications
AIMS: Evidence suggests a detrimental effect of diabetes mellitus (DM) on cancer incidence and outcomes. To date, the effect of DM and its treatment on prognosis in upper tract urothelial carcinoma (UTUC) remains uninvestigated. We tested the hypothesis that DM and metformin use impact oncologic outcomes of patients treated with radical nephroureterectomy (RNU) for UTUC.
METHODS: Retrospective analysis of 2492 patients with UTUC treated at 23 institutions with RNU without neoadjuvant therapy. Cox regression models addressed the association of DM and metformin use with disease recurrence, cancer-specific mortality and any-cause mortality.
RESULTS: A total of 365 (14.3%) patients had DM and 194 (7.8%) patients used metformin. Within a median follow-up of 36 months, 663 (26.6%) patients experienced disease recurrence, 545 patients (21.9%) died of UTUC and 884 (35.5%) patients died from any cause. Diabetic patients who did not use metformin were at significantly higher risk of disease recurrence and cancer-specific death compared to non-diabetic patients and diabetic patients who used metformin. In multivariable Cox regression analyses, DM treated without metformin was associated with worse recurrence-free survival (HR: 1.44, 95% CI 1.10-1.90, p = 0.009) and cancer-specific mortality (HR: 1.49, 95% CI 1.11-2.00, p = 0.008).
CONCLUSIONS: Diabetic UTUC patients without metformin use have significantly worse oncologic outcomes than diabetics who used metformin and non-diabetics. The possible mechanism behind the impact of DM on UTUC biology and the potentially protective effect of metformin need further elucidation.
