Evaluating Chemotherapy-induced Nausea and Vomiting and Food Intake in Patients With Gynecologic Cancer.
Anticancer Res. 2019; 39(8):4555-4560 [PubMed] Related Publications
PATIENTS AND METHODS: Subjects were females with gynecological cancers who underwent chemotherapy between 2008 and 2013. Nausea, anorexia, and food intake in the acute (day 1) and delayed phases (days 2 and 3) were retrospectively evaluated.
RESULTS: Subjects included 156 females. Chemotherapies were highly (HEC; n=24) and moderately emetogenic (MEC; n=132). There were no significant between-group differences for anorexia control during either the acute or the delayed phase and both groups demonstrated significantly worse control of nausea during the delayed phase. In the HEC group, food intake was significantly reduced on days 2 and 3 compared with day 1.
CONCLUSION: Rates of nausea, anorexia, and food intake significantly worsened over time, particularly in the MEC group. Current supportive therapies appear inadequate and should be improved.
Sentinel Nodes Detection with Near-infrared Imaging in Gynecological Cancer Patients: Ushering in an Era of Precision Medicine.
Isr Med Assoc J. 2019; 21(6):390-393 [PubMed] Related Publications
OBJECTIVES: To evaluate the detection rate of SLN with an indocyanine green and near-infrared fluorescent imaging (ICG/NIR) integrated laparoscopic system in clinically uterine-confined endometrial or cervical cancer.
METHODS: Patients with clinically early-stage endometrial or cervical cancer were included in this retrospective study. ICG was injected into the uterine cervix and an ICG/NIR integrated laparoscopic system was used during the surgeries. The National Comprehensive Cancer Network (NCCN) protocol was followed. SLN and/or suspicious lymph nodes were resected. Side-specific lymphadenectomy was performed when mapping was unsuccessful. Systematic lymphadenectomy was completed in patients with high-grade histology or deep myometrial invasion. Enhanced pathology using ultra-staging and immunohistochemistry were performed in all cases.
RESULTS: We analyzed 46 eligible patients: 39 endometrial and 7 cervical cancers. Of these, 44 had at least one SLN (93.6%). In 41 patients (89%) we detected bilateral SLN, in 3 (7%) only unilateral, and in 2 (4%) none were detected. Seven patients presented with lymph node metastasis. All were detected by NCCN/SLN protocol. Of these cases, two were detected with only pathological ultra-staging.
CONCLUSIONS: SLN mapping in endometrial and cervical cancer can easily be performed with a high detection rate by integrating ICG/NIR into a conventional laparoscopic system. Precision medicine in patients evaluated by SLN biopsy changes the way patients with endometrial or cervical cancer are managed.
Expanded validation of the EPIC bowel and urinary domains for use in women with gynecologic cancer undergoing postoperative radiotherapy.
Gynecol Oncol. 2019; 154(1):183-188 [PubMed] Related Publications
METHODS: In addition to the EPIC bowel domain, urinary toxicity (EPIC urinary domain), patient reported bowel toxicities (PRO-CTCAE) and quality of life (Functional Assessment of Cancer Therapy (FACT)) were completed before, during and after treatment. Sensitivity, reliability and concurrent validity were assessed.
RESULTS: Mean bowel and urinary scores among 278 women enrolled were significantly worse during treatment and differed between groups. Acceptable to good reliability for bowel and urinary domain scores were obtained at all time points with the exception of one at baseline. Correlations between function and bother scores within the bowel and urinary domains were consistently stronger than those across domains. Correlations between bowel domain scores and PRO-CTCAE during treatment were stronger than those with the FACT.
CONCLUSION: Correlations within and among the instruments indicate EPIC bowel and urinary domains are measuring conceptually discrete components of health. These EPIC domains are valid, reliable and sensitive instruments to measure PRO among women undergoing pelvic radiation.
Efficient use of patient-derived organoids as a preclinical model for gynecologic tumors.
Gynecol Oncol. 2019; 154(1):189-198 [PubMed] Related Publications
METHODS: We conducted 3D culture of 21 gynecologic tumors following our original and modified protocol for Matrigel bilayer organoid culture. We investigated whether propagated organoids retained various features of the original tumors by histopathological examination and targeted genome sequencing.
RESULTS: We customized the protocol we previously optimized for murine normal and cancer tissues, so as to circumvent the digestion-resistant nature inherent to gynecologic tumors. Indeed, this modified protocol improved the success rate from 45 to 90%, for robust propagation of organoids from tumors with various stages and subtypes. Finally, 14 patient-derived organoids were established. The recovered organoids were enriched for cancer cells that retained many aspects of the original tumors, including histological features, mutation profiles, and intra-tumoral heterogeneity. A subset of the expanded organoids could develop xenografts in immunodeficient mice, potentially paving the way to drug screening in vivo. Drug response assay in vitro for paclitaxel and cisplatin was feasible using organoid-derived spheroids.
CONCLUSIONS: We showed that patient-derived organoids closely resembled the original gynecologic tumors, and thereby would serve as a promising resource for preclinical studies.
Expression of circular RNAs in gynecological tumors: A systematic review.
Medicine (Baltimore). 2019; 98(20):e15736 [PubMed] Free Access to Full Article Related Publications
DATA SOURCES: This review was based on articles published in PubMed databases up to January, 2019, with the following keywords: "circular RNA", "database", and "reproductive tumor" (Flow chart).
OBJECTIVES: Original articles and reviews on the topics were selected.
RESULTS: Studies have uncovered the interplay between circRNAs and the development of ovarian epithelial tumors, ovarian carcinoma, and cervical carcinoma, which suggesting the potential of circRNAs as biomarkers or therapeutic targets for human diseases.
CONCLUSIONS: Circular RNA has been found to play a role in gynecological tumors diseases. Meanwhile, we reviewed the studies on how CircularRNA participate in gynecological tumors, which provides a basis for the study of CircularRNA in gynecological tumors.
The addition of paclitaxel to doxorubicin and cisplatin and volume-directed radiation does not improve overall survival (OS) or long-term recurrence-free survival (RFS) in advanced endometrial cancer (EC): A randomized phase III NRG/Gynecologic Oncology Group (GOG) study.
Gynecol Oncol. 2019; 154(1):13-21 [PubMed] Related Publications
METHODS: Prospective, randomized GOG trial comparing (CD) (50 mg/m
RESULTS: Since initial publication, 60 deaths occurred, leaving 311 patients alive with 290 (93.8%) recurrence- free. There was no significant decrease in the risk of recurrence or death associated with the CDP treatment regimen stratified for stage (p = 0.14, one-tail). The exploratory analysis for OS and the corresponding homogeneity tests for different effects across subgroups revealed only EFRT and EFRT & GRD status to have significantly different treatment effects (p = 0.027 and p = 0.017, respectively). Second primary malignancies were identified in 17/253 (6.4%) and 19/263 (7.0%) of patients treated with CD and CDP respectively. Breast (2.4%) followed by colon (1%) were the two cancers most frequently diagnosed in this setting.
CONCLUSION: No significant difference between treatment arms was identified. Subgroup analysis both in the initial and current reports demonstrated a trend towards improved RFS and OS in patients treated with CDP and EFRT. This long-term analysis of outcomes also identified the necessity of providing on-going cancer screening to patients enrolled in trials.
Financial toxicity in gynecologic oncology.
Gynecol Oncol. 2019; 154(1):8-12 [PubMed] Related Publications
METHODS: Follow-up patients at a gynecologic oncology practice completed a survey including the COmprehensive Score for Financial Toxicity (COST) tool and a self-reported overall health assessment, the EQ-VAS. We abstracted disease and treatment characteristics from medical records. We dichotomized COST scores into low and high financial toxicity and assessed the correlation (r) between COST scores and self-reported health. We calculated risk ratios (RR) and 95% confidence intervals (CI) for the associations of demographic and disease-related characteristics with high financial toxicity, as well as the associations between high financial toxicity and cost-coping strategies.
RESULTS: Among 240 respondents, median COST score was 29. Greater financial toxicity was correlated with worse self-reported health (r = 0.47; p < 0.001). In the crude analysis, Black or Hispanic race/ethnicity, government-sponsored health insurance, lower income, unemployment, cervical cancer and treatment with chemotherapy were associated with high financial toxicity. In the multivariable analysis, only government-sponsored health insurance, lower income, and treatment with chemotherapy were significantly associated with high financial toxicity. High financial toxicity was significantly associated with all cost-coping strategies, including delaying or avoiding care (RR: 7.3; 95% CI: 2.8-19.1).
CONCLUSIONS: Among highly-insured gynecologic oncology patients, many respondents reported high levels of financial toxicity. High financial toxicity was significantly associated with worse self-reported overall health and cost-coping strategies, including delaying or avoiding care.
Changes in functional brain networks and neurocognitive function in Chinese gynecological cancer patients after chemotherapy: a prospective longitudinal study.
BMC Cancer. 2019; 19(1):386 [PubMed] Free Access to Full Article Related Publications
METHODS: All research participants were evaluated using a resting-state functional magnetic resonance imaging and neurocognition assessment. Behavioral data were conducted using SPSS for descriptive statistics, correlation and comparison analyses. Preprocessing of MRI (Magnetic Resonance Imaging) data and network analyses were performed using GRETNA (Graph Theoretical Network Analysis).
RESULTS: A total of 40 subjects joined this study, with 20 subjects in each group. With the exception of the mean of psychomotor speed, there was no significant difference pre-chemotherapy between patients and healthy controls in neurocognitive test mean scores (Ps > 0.05). During the post-chemotherapy assessment, there were significant differences in the mean scores of neurocognitive tests (including Digit Span tests, verbal memory, immediate recall, delayed recall, and information processing speed tests) (all Ps < 0 .05). Longitudinal graph analysis revealed statistically significant differences in the patient group, with significant decreases in both local efficiency (P < 0.01) and global efficiency (P = 0.04). Lower raw TMT-A scores were significantly associated with lower local efficiency (r = 0.37, P = 0.03). Lower verbal memory scores were statistically significant and associated with lower global efficiency (r = 0.54, P = 0.02) in the patient group, but not in the healthy control group.
CONCLUSIONS: This study found that the risk of brain function and neurocognitive changes following chemotherapy could potentially guide patients in making appropriate treatment decisions, and this study may identify a cohort that could be suited for study of an intervention.
An international, phase III randomized trial in patients with mucinous epithelial ovarian cancer (mEOC/GOG 0241) with long-term follow-up: and experience of conducting a clinical trial in a rare gynecological tumor.
Gynecol Oncol. 2019; 153(3):541-548 [PubMed] Free Access to Full Article Related Publications
METHODS: We conducted a multicenter randomized factorial trial (UK and US). Patients were diagnosed with primary mEOC: FIGO stage II-IV or recurrence after stage I disease. Treatment arms were paclitaxel-carboplatin, oxaliplatin-capecitabine, paclitaxel-carboplatin-bevacizumab, or oxaliplatin-capecitabine-bevacizumab. Chemotherapy was given 3-weekly for 6 cycles, and bevacizumab (3-weekly) was continued as maintenance (for 12 cycles). Endpoints included overall-survival (OS), progression-free survival (PFS), toxicity and quality of life (QoL).
RESULTS: The trial stopped after 50 patients were recruited due to slow accrual. Median follow-up was 59 months. OS hazard ratios (HR) for the two main comparisons were: 0.78 (p = 0.48) for Oxal-Cape vs. Pac-Carbo (each with/without bevacizumab), and 1.04 (p = 0.92) for bevacizumab vs. no bevacizumab. Corresponding PFS HRs were: 0.84 and 0.80. Retrospective central pathology review revealed only 45% (18/40) cases with available material had confirmed primary mEOC. Among these, OS HR for Oxal-Cape vs. Pac-Carbo was 0.36 (p = 0.14); PFS HR = 0.62 (p = 0.40). Grade 3-4 toxicity was seen in 61% Pac-Carbo, 61% Oxal-Cape, 54% Pac-Carbo-Bev, and 85% Oxal-Cape-Bev. QoL was similar between the four arms.
CONCLUSION: mEOC/GOG0241 represents an example of a randomized rare tumor trial. Logistical challenges led to early termination, including difficulties in local histopathological diagnosis and accessing drugs outside their labelled indication. There was misalignment between central funders who support clinical trials in rare cancers and the deprioritisation of such work by those managing and funding research at a local level. Rare cancer trials should include centralised pathology review before treatment. Clinical trial registry number: ISRCTN83438782.

Constitutively active ESR1 mutations in gynecologic malignancies and clinical response to estrogen-receptor directed therapies.
Gynecol Oncol. 2019; 154(1):199-206 [PubMed] Related Publications
METHODS: DNA from FFPE tumor tissue obtained during routine clinical care for 9645 gynecologic malignancies (ovary, fallopian tube, uterus, cervix, vagina, vulvar, and placenta) was analyzed for all classes of genomic alterations (base substitutions (muts), insertions, deletions, rearrangements, and amplifications) in ESR1 by hybrid capture next generation sequencing. A subset of alterations was characterized in laboratory-based transcription assays for response to endocrine therapies.
RESULTS: A total of 295 ESR1 genomic alterations were identified in 285 (3.0%) cases. mutESR1 were present in 86 (0.9%) cases and were more common in uterine compared to other cancers (2.0% vs <1%, respectively p < 0.001). mutESR1 were enriched in carcinomas with endometrioid versus serous histology (4.4% vs 0.2% respectively, p < 0.0001 in uterine and 3.5% vs 0.3% respectively, p = 0.0004 in ovarian carcinomas). In three of four patients with serial sampling, mutESR1 emerged under the selective pressure of AI therapy. Despite decreased potency of estrogen receptor (ER) antagonists in transcriptional assays, clinical benefit was observed following treatment with selective ER-targeted therapy, in one case lasting >48 months.
CONCLUSIONS: While the prevalence of ESR1 mutations in gynecologic malignancies is low, there are significant clinical implications useful in guiding therapeutic approaches for these cancers.
Gynecologic oncology providers endorse practice-changing impact of communication skills training.
Gynecol Oncol. 2019; 153(3):633-638 [PubMed] Related Publications
METHODS: We developed and conducted a two-day CST workshop with an interprofessional group of 20 GO providers over two years. Participants were surveyed pre-workshop, immediately post-workshop and one month post-workshop regarding self-assessed preparedness to handle challenging communication tasks, workshop evaluation and impact on practice. McNemar's tests were used for pre-post comparisons.
RESULTS: Of 12 challenging communication tasks assessed, all participants reported improvement in at least one, with a median of 10. The proportion of participants feeling more than "somewhat prepared" improved significantly for all communication tasks assessed (p < 0.05); improvement was sustained one month later. One month post-workshop, 86% reported thinking about what they had been taught at least weekly and 93% reported encountering situations where they used their CST skills at least weekly. Rates of reported practice-changing impact were >75% for each communication skill. All participants rated the CST educational quality very good or excellent and strongly agreed it should be required of all GO clinicians.
CONCLUSIONS: Participants felt the workshop provided high-quality, practice-changing education. As a result of the workshop, participants reported statistically significant, sustained improvement in preparedness to handle challenging communication tasks. CST for GO providers is feasible, with high rates of perceived effectiveness and impact on clinical practice. CST workshops should be integrated into GO training.
Increased risk for depression persists for years among women treated for gynecological cancers - a register-based cohort study with up to 19 years of follow-up.
Gynecol Oncol. 2019; 153(3):625-632 [PubMed] Related Publications
METHODS: We followed 16,833 women diagnosed with gynecological cancers between 1998 and 2013 and 138,888 reference women in nationwide registers for up to 19 years. Women with a history of severe psychiatric disorders, and those who had redeemed a prescription for antidepressants three years before study entry were excluded from analyses. Regression analyses were applied to compare the risk for antidepressant use among patients compared to reference women, and to investigate associations between socio-demographic as well as clinical risk factors and use of antidepressants.
RESULTS: We found an increased risk for antidepressant use among women treated for ovarian (HR 4.14, 95% CI 3.74-4.59), endometrial (HR 2.19, 95% CI 1.97-2.45), and cervical cancer (HR 3.14, 95% CI 2.74-3.61) one year after diagnosis. This increased risk persisted years after diagnosis in all three groups, with the longest (up to eight years) found for ovarian cancer. Advanced disease was strongly associated with antidepressant use followed by short education, and comorbidity.
CONCLUSIONS: Women diagnosed with gynecological cancer have an increased risk for depression compared to reference women. The risk remains increased for years after diagnosis throughout and beyond standard oncological follow-up care. Advanced disease, short education, and comorbidity are factors associated with antidepressant use in this patient group.
Outcomes of non-high grade serous carcinoma after neoadjuvant chemotherapy for advanced-stage ovarian cancer: a Korean gynecologic oncology group study (OV 1708).
BMC Cancer. 2019; 19(1):341 [PubMed] Free Access to Full Article Related Publications
METHODS: We conducted a retrospective cohort study of patients who underwent NAC for advanced stage non-HGSC between 2002 and 2017 in 17 institutions. Demographics, surgical outcomes, and survival rates were evaluated according to histological subtypes.
RESULTS: A total of 154 patients were included in this study, comprising 20 cases (13.0%) of mucinous adenocarcinoma, 31 cases (20.1%) of endometrioid adenocarcinoma, 28 (18.2%) cases of clear cell carcinoma, 29 (18.8%) cases of low-grade serous carcinoma and 12 cases (7.8%) of carcinosarcoma. Complete remission/partial remission after the third cycle of NAC was achieved in 100 (64.9%) patients and optimal debulking surgery (residual disease ≤1 cm) at interval debulking surgery was achieved in 103 (66.9%) patients. The most common reason for performing NAC was high tumor burden (n = 106, 68.8%). The median progression-free survival (PFS) was 14.3 months and median overall survival (OS) was 52.9 months. In multivariate analyses, mucinous and clear cell carcinoma were negative prognostic factors for both PFS (p = 0.007 and p = 0.017, respectively) and OS (p = 0.002 and p = 0.013, respectively).
CONCLUSIONS: In this study, poor survival outcomes were observed in patients with mucinous and clear cell carcinoma undergoing NAC. Different treatment strategies are urgently required to improve survival outcomes for this disease subset.
Short-course olanzapine to prevent delayed emesis following carboplatin/paclitaxel for gynecologic cancer: a randomised study.
Tumori. 2019; 105(3):253-258 [PubMed] Related Publications
METHODS: This was a prospective study in 81 chemo-naive patients receiving 0.25 mg intravenous palonosetron, 16 mg dexamethasone, and 10 mg oral olanzapine before chemotherapy. On days 2 and 3, patients randomly received 10 mg olanzapine (arm A; n=27), 10 mg olanzapine plus 4 mg dexamethasone (arm B; n=27), or 8 mg dexamethasone (reference arm C; n=27). The primary endpoint was total control (TC; no vomiting, no rescue antiemetics, and no nausea) on days 2-5, using a diary. Secondary endpoints included proportion of patients with no emesis impact on daily life using the Functional Living Index-Emesis (FLIE) questionnaire, and patient's satisfaction with antiemetic coverage.
RESULTS: Fifty-two percent of patients in arm A (
CONCLUSIONS: In this exploratory study with a small sample size, we did not find any clue about better control of delayed emesis with either olanzapine regimen in gynecologic cancer patients treated with carboplatin/paclitaxel and receiving the same prophylaxis for acute emesis.

Utilizing the Patient Reported Outcomes Measurement Information System (PROMIS®) to increase referral to ancillary support services for severely symptomatic patients with gynecologic cancer.
Gynecol Oncol. 2019; 152(3):509-513 [PubMed] Related Publications
METHODS: English-speaking patients with a confirmed history of gynecologic cancer completed PROMIS ePROs on iPads in the waiting area of an outpatient gynecologic oncology clinic. Symptom scores were calculated for each respondent and grouped using documented severity thresholds. Response data was compared with clinicopathologic characteristics across symptom domains. Severely symptomatic patients were offered referral to ancillary services and asked to complete post-exposure surveys assessing acceptability of the ePRO.
RESULTS: Of the 336 patients who completed ePROs, 35% had active disease and 19% had experienced at least one disease recurrence. Sixty-nine percent of the cohort demonstrated moderate to severe physical dysfunction (60%), pain (36%), fatigue (28%), anxiety (9%), depression (8%), and sexual dysfunction (32%). Thirty-nine (12%) severely symptomatic patients were referred to services such as psychiatry, palliative care, pain management, social work or integrative oncology care. Most survey respondents identified the ePROs as helpful (78%) and easy to complete (92%).
CONCLUSIONS: Outpatient PROMIS ePRO administration is feasible and acceptable to gynecologic oncology patients and can help identify severely symptomatic patients for referral to ancillary support services.
Validation and application of a module of the MD Anderson Symptom Inventory for measuring perioperative symptom burden in patients with gynecologic cancer (the MDASI-PeriOp-GYN).
Gynecol Oncol. 2019; 152(3):492-500 [PubMed] Article available free on PMC after 01/03/2020 Related Publications
METHODS: Our process included: (1) generating PeriOp-GYN-specific candidate items from qualitative interviews with patients, followed by input from an expert panel; (2) dropping items that lacked independent clinical relevance; (3) validating psychometric properties (reliability, validity) of the resulting MDASI-PeriOp-GYN; and (4) conducting cognitive debriefing interviews with patients to confirm ease of comprehension, relevance, and acceptability.
RESULTS: Qualitative interviews with 40 patients generated 9 new PeriOp-GYN symptom items (bloating, abdominal cramping, constipation, hot flashes, dizziness, grogginess/confusion, urinary pain, difficulty urinating, and diarrhea) that, along with the core MDASI items, formed the new MDASI-PeriOp-GYN. A total of 150 patients (minimally invasive surgery (MIS) = 69, open surgery = 81) participated in the validation study; 121 patients also provided retest data. Cronbach alphas were 0.89 for symptoms and 0.86 for interference. Test-retest reliability was 0.88 for all symptom severity items. Known-group validity was supported by the detection of significant differences in symptom and interference levels by performance status (P < 0.01) and for all symptoms by surgery type (P < 0.01). Cognitive debriefing with 20 of the 150 patients demonstrated that the MDASI-PeriOp-GYN is an easy-to-use and understandable tool.
CONCLUSIONS: The MDASI-PeriOp-GYN is a valid, reliable, concise tool for measuring symptom severity and functional interference in patients undergoing gynecologic surgery and can be useful in assessing postoperative symptom burden via PROs.

Impact of a preventive bundle to reduce surgical site infections in gynecologic oncology.
Gynecol Oncol. 2019; 152(3):480-485 [PubMed] Related Publications
METHODS: A SSI prevention bundle was implemented in February 2017 including: preoperative chlorhexidine shower, prophylactic antibiotics, glycemic control, normothermia, and separate closing tray. Data were collected prospectively using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) institutional data, and chart review of surgeries between January 2016 and September 2017 was performed. The primary outcome was rate of SSIs, secondary outcomes were: superficial, deep and organ space SSIs, sepsis, wound disruption, length of stay, 30-day readmission and reoperation. Logistic regression analysis was conducted to identify predictors of SSIs.
RESULTS: 339 baseline and 224 post-intervention patients were included. 53 incurred one or more SSIs: 43 superficial, 6 deep, and 14 organ-space. The bundle decreased overall SSIs by 55% (12.1% to 5.4%, p = 0.008) and superficial SSIs by 54% (9.7% to 4.5%, p = 0.023). Improvement was sustained for 6 quarters. No significant difference was found in other secondary outcomes. On multivariable analysis, surgery in the pre-bundle period, BMI ≥30, laparotomies and longer operative duration were independent risk factors for overall SSIs (OR 2.23, 95% CI 1.06-5.06, -OR 3.01, 95% CI 1.57 - 5.87, OR 3.70, 95% CI 1.56 - 10.18 and - OR 2.16, 95% 1.11 - 4.19, respectively).
CONCLUSIONS: This prevention bundle successfully decreased SSIs in patients undergoing gynecologic cancer surgery. We recommend improving quality of care by wide implementation of SSI prevention bundles in Gynecologic Oncology patients.

The mesenchymal transition subtype more responsive to dose dense taxane chemotherapy combined with carboplatin than to conventional taxane and carboplatin chemotherapy in high grade serous ovarian carcinoma: A survey of Japanese Gynecologic Oncology Group study (JGOG3016A1).
Gynecol Oncol. 2019; 153(2):312-319 [PubMed] Related Publications
METHODS: We conducted the Japanese Gynecologic Oncology Group (JGOG) 3016A1 study, wherein we collected hematoxylin and eosin slides (total n = 201) and performed a histopathological analysis of patients with HGSOC registered in the JGOG3016 study, which compared the efficacy of conventional paclitaxel and carboplatin (TC) and dose-dense TC (ddTC). We analyzed the differences in progression-free survival (PFS) and overall survival (OS) among the four histopathological subtypes. We then compared the PFS between the TC group and the ddTC group for each histopathological subtype.
RESULTS: There were significant differences in both PFS and OS among the four histopathological subtypes (p = 0.001 and p < 0.001, respectively). Overall, the MT subtype had the shortest PFS (median 1.4 y) and OS (median 3.6 y). In addition, the MT subtype had a longer PFS in the ddTC group (median 1.8 y) than in the TC group (median 1.2 y) (p = 0.01). Conversely, the other types had no significant difference in PFS when the two regimens were compared.
CONCLUSIONS: The MT type of HGSOC is sensitive to taxane; therefore, the ddTC regimen is recommended for this histopathological subtype.

GOG 8020/210: Risk stratification of lymph node metastasis, disease progression and survival using single nucleotide polymorphisms in endometrial cancer: An NRG oncology/gynecologic oncology group study.
Gynecol Oncol. 2019; 153(2):335-342 [PubMed] Article available free on PMC after 01/03/2020 Related Publications
METHODS: Surgically-staged EEC patients from the Gynecologic Oncology Group or Washington University School of Medicine with germline DNA available were eligible. Fifty-four genes represented by 384 SNPs, were evaluated by Illumina Custom GoldenGate array. Association with lymph node metastases was the primary outcome. Progression-free survival (PFS) and overall survival (OS) was also evaluated.
RESULTS: 361 SNPs with high quality genotype data were evaluated in 337 patients with outcome data. Five SNPs in CXCR2 had an odds ratio (OR) between 0.68 and 0.70 (p-value ≤ 0.025). The A allele rs946486 in ABL had an OR of 1.5 (p-value = 0.01) for metastasis. The G allele in rs7795743 in EGFR had an OR for metastasis of 0.68 (p-value = 0.02) and hazard ratio (HR) for progression of 0.66 (p-value = 0.004). Importantly, no SNP met genome wide significance after adjusting for multiple test correcting and clinical covariates. The A allele in rs2159359 SNP in NME1 and the G allele in rs13222385 in EGFR were associated with worse OS. Both exhibited genome wide significance; rs13222385 remained significant after adjusting for prognostic clinical variables.
CONCLUSION: SNPs in cancer genes including rs2159359 SNP in NME1 and rs13222385 in EGFR may stratify risk in EEC and are prioritized for further investigation.
Impact of a documentation intervention on health-assessment metrics on an inpatient gynecologic oncology service.
Gynecol Oncol. 2019; 153(2):385-390 [PubMed] Related Publications
METHODS: We performed a pre- versus post-implementation analysis to assess the impact of a documentation intervention bundle on calculated admission/discharge SOI/ROM scores on an inpatient gynecologic oncology service. Introduced in January 2017, the bundle included educational in-service, introduction of problem-based progress notes, a documentation tip ID badge and video, and weekly chart audits. Admission/discharge SOI/ROM scores (range 1-4) were obtained from hospital performance services. Demographics and 30-day mortality were collected from electronic medical records for all inpatients in historic (calendar year 2015) and intervention (2017) cohorts. Primary outcomes (discharge SOI/ROM) were modelled using ordinal and multinomial logistic regressions, controlling for confounders. 30-day observed/expected mortality ratios were reported for each cohort.
RESULTS: 629 patients were included: 378 (60%) in 2015, 251 (40%) in 2017. Increased odds of having higher SOI score were observed in the intervention cohort for medical (OR = 2.22; 95% CI 1.38, 3.58) and surgical admissions (OR = 2.63; 95% CI 1.47, 4.40). Surgical (OR = 5.54; 95% CI 1.29, 23.96), but not medical (OR = 1.45; 95% CI 0.46, 4.57), admissions in the intervention cohort had higher odds of having the worst ROM score. Observed/expected mortality was 0.24 in the intervention compared to 0.37 in historic cohort (p = 0.58, NS).
CONCLUSION: An intervention bundle to improve physician documentation accuracy resulted in higher discharge SOI scores for medical and surgical admissions.
