"A second-generation cisplatin analogue with antineoplastic activity. Containing a novel ring structure in which glycolate is bound to the platinum by a bidentate ligand, nedaplatin forms reactive platinum complexes that bind to nucelophillic groups in DNA, resulting in intrastrand and interstrand DNA cross-links, apoptosis and cell death. This agent appears to be less nephrotoxic and neurotoxic compared to both cisplatin and carboplatin." (NCI Thesaurus)

Platinum-Based Adjuvant Chemotherapy for Stage II and Stage III Squamous Cell Carcinoma of the Lung.
Ann Thorac Cardiovasc Surg. 2017; 23(1):19-25 [PubMed] Related Publications
MATERIALS AND METHODS: The prognoses of 94 patients with stage II and stage III SCC with or without PBAC (more than three courses of cisplatin-, carboplatin-, and nedaplatin-based adjuvant chemotherapy) were compared.
RESULTS: The mean observation period was 46.1 months. PBAC was not administered for the following reasons: 39 (55.7%) patients had comorbidities, 25 (35.7%) were older than 75 years, 19 (27.1%) patients underwent surgery before the approval of PBAC, and 3 (4.3%) patients could not continue PBAC (≤2 cycles) because of adverse events. PBAC patients (n = 24) were significantly younger than non-PBAC patients (n = 70; 66.3 vs 69.6 years old, respectively; p = 0.043). Disease-free survival (DFS) did not differ between PBAC and non-PBAC patients (55.0% and 67.1%, respectively; p = 0.266). PBAC patients tended to have worse overall survival (OS) than non-PBAC patients (56.1% and 70.2%, respectively; p = 0.138). PBAC was not prognostic for OS (hazard ratio (HR), 2.11; 95% confidence interval (CI), 0.82%-5.40%; p = 0.120).
CONCLUSION: PBAC did not improve the prognoses of patients with pathological stage II or stage III SCC in the single institution experience.

The Influence of Neoadjuvant Chemotherapy with Docetaxel, Nedaplatin and 5-Fluorouracil After Esophagectomy.
Anticancer Res. 2016; 36(11):6165-6171 [PubMed] Related Publications
PATIENTS AND METHODS: We investigated the perioperative white blood cell count (WBC), C-reactive protein (CRP), serum albumin, body temperature (BT), heart rate (HR), respiratory rate (RR), water balance, partial pressure of oxygen in arterial blood (PaO2)/fraction of inspired oxygen (FiO2) ratio, postoperative complications and systemic inflammatory response syndrome (SIRS) in patients who underwent NAC or surgery alone (SA group).
RESULTS: In the NAC group, the preoperative WBC (p=0.015) and postoperative day (POD) 3 BT (p=0.049), as well as RR (p=0.037) were lower, whereas the POD 2 PaO2/FiO2 ratio was higher (p=0.047), compared to the SA group. No differences in the incidence of postoperative complications and SIRS were observed between the groups.
CONCLUSION: NAC using docetaxel, nedaplatin and 5-fluorouracil was tolerated and feasible in esophageal cancer.

Prognostic factors in clinical T1N0M0 thoracic esophageal squamous cell carcinoma invading the muscularis mucosa or submucosa.
Radiat Oncol. 2016; 11:84 [PubMed] Free Access to Full Article Related Publications
METHODS: We retrospectively reviewed the medical charts of 90 patients with clinical T1N0M0 thoracic ESCC treated with RT or CRT in our hospital in 2004-2011. Of these 90 patients, we analyzed the cases of 71 patients who met our inclusion criteria. All 71 patients had MM or SM cancer. In the 47 patients treated with CRT, the chemotherapy regimen of 5-fluorouracil (5-FU) plus cisplatin (CDDP) was used for 46 patients and 5-FU and nedaplatin was used for one patient. Forty-five patients underwent endoscopic resection (ER) followed by RT or CRT as an additional treatment. Elective nodal irradiation (ENI) was used in 39 patients. For all analyses, statistical significance was defined as 0.05, and the Bonferroni correction was used for the multivariate analysis.
RESULTS: The median age was 70 years (range 47-84). With a median follow-up of 43.6 months (range 1.5-124.2), the 5-year overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS) rates were 64.0, 72.8 and 50.0 %, respectively. The multivariate analysis showed that performance status (PS) was an independent prognostic factors for DSS and DFS (DSS, p < 0.001; DFS, p < 0.001). Chemotherapy in addition to RT showed a trend for better DSS (p = 0.032) but was not significant following Bonferroni correction. ER and ENI were not significant predictive factors for DSS and DFS.
CONCLUSIONS: PS was an independent prognostic factor for DSS and DFS. ER and ENI had no significant relationship with DSS or DFS. The present results may be helpful in treatment decisions for clinical T1N0M0 thoracic ESCC.

Efficacy and Safety of Biweekly Docetaxel in Combination with Nedaplatin as Second-line Chemotherapy for Unresectable or Recurrent Esophageal Cancer.
Anticancer Res. 2016; 36(4):1923-7 [PubMed] Related Publications
PATIENTS AND METHODS: In total, 33 patients with recurrent esophageal cancer after initial treatment (esophagectomy, chemotherapy, or chemoradiotherapy) were enrolled. Patients received docetaxel (30 mg/m(2)intravenously) and nedaplatin (30 mg/m(2)intravenously) on day 1 biweekly. The response rate (RR), time to treatment failure (TTF), overall survival time (OS), and toxicity were analyzed.
RESULTS: The median number of cycles of combination therapy was five (range=2-25 cycles). The RR was 21.2%, and the disease control rate was 60.6%. The median TTF was 71 days, and median OS was 211 days. The most frequent toxicities were leukopenia and anemia; non-hematological toxicities were generally mild. There were no treatment-related deaths.
CONCLUSION: This outpatient combination chemotherapy was useful as second-line chemotherapy for unresectable or recurrent esophageal cancer.

METHODS: A total of 171 patients with ABC (admission between July 2008 and July 2013) were retrospectively analyzed. Patients received either nedaplatin 75 mg/m(2) (arm N; n = 85) or cisplatin 75 mg/m(2) (arm C; n = 86) in combination with other second-generation chemotherapeutic drugs, such as paclitaxel 175 mg/m(2), docetaxel 75 mg/m(2), gemcitabine 1.25 g/m(2), and navelbine 25 mg/m(2) every 21 days (nedaplatin, cisplatin, paclitaxel, docetaxel on day 1; gemcitabine, navelbine on days 1 and 8). The primary endpoint was TTF in each arm; secondary endpoints were OS, ORR, and toxicity.
RESULTS: In the assessable patient population, in arm N, median TTF and OS was 13.87 months (95% CI: 11.55-16.19) and 31.53 months (95% CI: 28.42-34.64), respectively, with an ORR of 48.2%. In arm C, median TTF and OS was 8.7 months (95% CI: 5.82-11.59) and 24.87 months (95% CI: 18.98-30.75), respectively, with an ORR of 37.2%. The occurrence of grades 3 and 4 hematologic toxicity was more frequent (45.9% vs. 25.6%, p = 0.003) in arm N than in arm C. However, grade ≥2 nonhematologic toxicity was less frequent in arm N than in arm C (12.9% vs. 46.5%, p = 2.05 × 10(-7)).
CONCLUSIONS: Nedaplatin-based chemotherapy regimen was well tolerated and efficiently improved patients' quality of life characterized by prolonged TTF and OS, with a marginal ORR.

Hepatogastroenterology. 2015; 62(140):898-901 [PubMed] Related Publications
METHODOLOGY: We examined 32 patients with T4 thoracic esophageal SCC who received neoadjuvant CRT followed by surgery.
RESULTS: Pathological complete response (pCR) was achieved in 7 patients (21.9%). pCR was significant correlated with standardized uptake value (SUV) after neoadjuvant CRT (P = 0.034) and SUV decrease (%) (P = 0.030). The optimal cut-off values to predict pCR were 2.25 for SUV after neoadjuvant CRT and 79.3 for SUV decrease (%). Of note, no patients who did not reach both cut-off values achieved pCR. Conclusions: SUV after CRT and SUV decrease (%) in FDG-PET of the primary tumor are useful tools to predict pathological response of neoadjuvant CRT for T4 esophageal SCC.

Phase I trial of nedaplatin chemotherapy concurrent with radiotherapy for untreated locoregionally advanced nasopharyngeal carcinoma.
Cancer Chemother Pharmacol. 2016; 77(3):643-51 [PubMed] Related Publications
EXPERIMENTAL DESIGN: Twenty patients were enrolled. The eligibility criteria included local advanced NPC (stage III or IVa) without any previous treatment and an expected survival of ≥ 3 months. The regimen consisted of 1.8-2.0 Gy daily radiation for 5 days a week and NDP with dose escalation of 70-100 mg/m(2) on day 1. The cycles were repeated every 21 days (day 1, day 22 and day 43) until the completion of chemoradiation. Dose-limiting toxicities (DLTs) included: grade 4 anemia; grade 4 neutropenia lasting for ≥ 5 days; grades 3 and 4 febrile neutropenia; grade 4 thrombocytopenia; grades 3-4 non-hematological toxicity (with the exception of alopecia, nausea) and any of the grade 5 responses.
RESULTS: Ninety-five percent of the assessed patients experienced a treatment response. The median time to progression among all patients was 41.9 months. Two-year overall survival was 95%, while the progression-free survival was 85%. DLT included febrile neutropenia of grade 3. The RD of NDP was 90 mg/m(2) during cycles 1-3.
CONCLUSION: NDP combined with radiotherapy and administered every 21 days for three cycles was active in patients with locoregionally advanced NPC. The regimen resulted in mild adverse effects and good patient compliance. Based on the findings from the study, the RD of NDP for phase II trial was found to be 90 mg/m(2).
Clinical efficacy of neoadjuvant chemotherapy with irinotecan (CPT-11) and nedaplatin followed by radical hysterectomy for locally advanced cervical cancer.
J Int Med Res. 2016; 44(2):346-56 [PubMed] Related Publications
METHODS: Patients with locally advanced cervical cancer (stage Ib2-IIb) were treated with NAC followed by surgery, primary surgery or primary radiotherapy. NAC was usually performed using transuterine arterial chemotherapy (TUAC) or intravenous CPT-11/NED. Survival rates were analysed in the three treatment groups; response rates and adverse events associated with NAC, TUAC and CPT-11/NED were compared, along with previously reported adverse events of chemoradiotherapy.
RESULTS: A total of 165 patients with cervical cancer were recruited. Of these, 70 were treated with NAC followed by surgery (48 with CPT-11/NED, 18 with TUAC and four with other types of chemotherapy), 73 were treated with primary surgery and 22 with primary radiotherapy (including chemoradiotherapy). There were no significant differences in progression-free survival or overall survival rates between the three treatment groups. The response rates for the NAC regimen of CPT-11/NED and TUAC were high (75% and 78%, respectively). The frequency of severe thrombocytopenia was lower in patients receiving CPT-11/NED compared with TUAC, and the incidence of severe anaemia, vomiting and cystitis was lower in patients receiving CPT-11/NED compared with chemoradiotherapy.
CONCLUSIONS: The use of CPT-11/NED as a NAC regimen shows favourable activity, with lower toxicity compared with NAC using TUAC or chemoradiotherapy, for the treatment of locally advanced cervical cancer.

Int J Clin Oncol. 2016; 21(4):735-40 [PubMed] Related Publications
METHODS: The medical records of patients with cervical cancer who had undergone CCRT between 2003 and 2007 were retrospectively reviewed. Of these, 129 patients were treated postoperatively with CCRT (n = 52) or primary CCRT (n = 77). A total of 29 patients were treated with nedaplatin-based postoperative CCRT and 23 patients were treated with cisplatin-based postoperative CCRT. A total of 28 patients were treated with nedaplatin-based postoperative CCRT, and 49 patients were treated with cisplatin-based postoperative CCRT. Progression-free survival (PFS) and overall survival (OS) were compared between the treatment groups.
RESULTS: With postoperative CCRT, there were no significant differences in recurrence rate (P = 1.0000), PFS (log-rank: P = 0.8503), and OS (log-rank: P = 0.8926) between the two treatment groups. With primary CCRT, there were no significant differences in PFS (log-rank: P = 0.7845) and OS (log-rank: P = 0.3659). The frequency of acute toxicity was not significantly different between the cisplatin-based postoperative CCRT group and the nedaplatin-based postoperative CCRT group.
CONCLUSIONS: Nedaplatin-based postoperative CCRT is an effective and well-tolerated regimen for both early-stage and advanced-stage cervical cancer patients.
Efficacy and feasibility of ambulatory treatment-based monthly nedaplatin plus S-1 in definitive or salvage concurrent chemoradiotherapy for early, advanced, and relapsed esophageal cancer.
Radiat Oncol. 2016; 11:4 [PubMed] Free Access to Full Article Related Publications
METHODS: Patients with early and advanced esophageal cancer and relapsed esophageal cancer after radical surgery were included. Nedaplatin 80 mg/m(2) was given on days 1 and 29, and S-1 80 mg/m(2) on days 1-14 and 29-42. No prophylactic treatment with granulocyte colony stimulating factor was administered. Patients received two courses of concurrent radiotherapy of more than 50 Gy with or without two additional courses as adjuvant therapy every 4 weeks.
RESULTS: Between August 2011 and June 2015, 89 patients (age range, 44-86 years; K-PS 90-100, 81 %; squamous cell carcinoma histology, 97 %; definitive/salvage CRT, 75/25 %) were collected. Twenty-one (24 %) patients completed four cycles, and 94 % received two or more cycles. Grade 4 leukopenia, thrombocytopenia, and anemia occurred in 12, 7, and 10 % of the patients, respectively. Five patients developed febrile neutropenia. Grade 3 non-hematological toxicity included infection in 12 %, mucositis/esophagitis in 3 %, kidney in 3 %, and fatigue in 3 %. Sixty-four patients (72 %) received the prescribed full dose and full cycles of chemotherapy. A complete response was achieved in 76 patients (85 %). The 3-year overall survival rate was 54.4 % in definitive CRT and 39.8 % in salvage CRT, respectively. Sixty-two subjects (70 %) received treatment as outpatients.
CONCLUSIONS: Nedaplatin and S-1 in combination with radiotherapy is feasible, and toxicity is tolerable. This treatment method has the potential to shorten hospitalization without impairing the efficacy of CRT.
Novel cytotoxic drugs in advanced nonsmall cell lung cancer.
Curr Opin Oncol. 2016; 28(2):110-4 [PubMed] Related Publications
RECENT FINDINGS: Nab-paclitaxel and carboplatin as first-line treatment should be considered a therapeutic option, particularly in patients with squamous histology. Nedaplatin and docetaxel improves survival in Asiatic patients with squamous histology as compared with cisplatin and docetaxel.
SUMMARY: NSCLC is a heterogeneous disease with limited available treatment options in the absence of specific molecular alterations. Defining the histological subgroup has an impact on the selection of molecular screening and therapy options. Chemotherapy has reached a plateau of effectiveness showing an overall survival of about 10 months. Therefore, some cytotoxic and antiangiogenic agents display improved efficacy in defined patient subgroups and may lead to prolonged survival. Despite this, the overall outlook of lung cancer survival for most patients remains dismal.

Drug Des Devel Ther. 2015; 9:6401-5 [PubMed] Free Access to Full Article Related Publications
METHODS: In this multicenter Phase II trial, the patients were treated with intravenous docetaxel (75 mg/m(2), day 1) and nedaplatin (80 mg/m(2), day 1), each cycle repeated every 3 weeks for two cycles at least.
RESULTS: From January 2010 to November 2013, a total of 78 patients were recruited in this trial. Among them, 73 patients were assessable for response. The treatment was well tolerated. The main hematological adverse event was neutropenia. A total of 12 patients (15.4%) had grade 3 or grade 4 neutropenia. Grade 3 anemia was observed in six patients (7.7%) and no grade 3/4 thrombocytopenia was observed. No Grade 3/4 non-hematological toxicity was observed. There were five complete response (6.8%), 43 partial responses (58.9%), and the overall response rate was 65.8% (95% confidence interval [CI], 48.7%-81.2%). With a median follow-up period of 18.6 months, the median time to progression was 7.9 months (95% CI, 4.2-10.8 months), median overall survival was 15.7 months (95% CI, 11.6-18.5 months).
CONCLUSION: Docetaxel combined with nedaplatin offers a satisfactory clinical activity and an acceptable safety profile as first-line chemotherapy for patients with recurrent and metastatic nasopharyngeal carcinoma.

Nedaplatin plus docetaxel versus cisplatin plus docetaxel for advanced or relapsed squamous cell carcinoma of the lung (WJOG5208L): a randomised, open-label, phase 3 trial.
Lancet Oncol. 2015; 16(16):1630-8 [PubMed] Related Publications
METHODS: We did a randomised, open-label, phase 3 study at 53 institutions in Japan. Eligibility criteria included pathologically proven squamous cell lung cancer with stage IIIB/IV or postoperative recurrence, age 20-74 years, Eastern Cooperative Oncology Group performance status of 0-1, no previous chemotherapy or recurrence more than a year after previous adjuvant chemotherapy, and adequate organ function. Patients were randomly assigned (1:1) to 100 mg/m(2) nedaplatin and 60 mg/m(2) docetaxel intravenously, or 80 mg/m(2) cisplatin and 60 mg/m(2) docetaxel, every 3 weeks for four to six cycles (at the treating oncologist's discretion). Randomisation was done centrally at the West Japan Oncology Group data centre via a computer-generated allocation sequence with dynamic minimisation that balanced stage (IIIB/IV or postoperative recurrent), sex, and institution. The primary endpoint was overall survival in the modified intention-to-treat population (ie, all patients who were randomly assigned and met the inclusion criteria). Safety analyses were done in all randomly assigned patients who received at least one dose of the study regimen. This trial is registered with the UMIN Clinical Trials Registry, number UMIN000002015, and is closed to new participants.
FINDINGS: Between July 6, 2009, and July 26, 2012, 355 patients were randomly assigned. 349 patients were included in the modified intention-to-treat analysis (177 in the nedaplatin group and 172 in the cisplatin group). Overall survival was significantly longer in the nedaplatin group (median 13·6 months, 95% CI 11·6-15·6) than in the cisplatin group (11·4 months,10·2-12·2; hazard ratio 0·81, 95% CI 0·65-1·02; p=0·037, one-sided stratified log-rank test). Grade 3 or worse nausea (seven of 177 patients in the nedaplatin group and 25 of 175 in the cisplatin group), fatigue (six vs 20), hyponatraemia (24 vs 53), and hypokalaemia (four vs 15) were more frequent in the cisplatin group than in the nedaplatin group, whereas grade 3 or worse leucopenia (98 vs 77), neutropenia (146 vs 123), and thrombocytopenia (16 vs none) were more frequent in the nedaplatin group than in the cisplatin group. Treatment-related deaths occurred in four and three patients in nedaplatin and cisplatin groups, respectively.
INTERPRETATION: Overall survival was significantly longer with nedaplatin plus docetaxel than with cisplatin plus docetaxel, and the regimens had different safety profiles. Nedaplatin plus docetaxel could be a new treatment option for advanced or relapsed squamous cell lung cancer.

Long-term results of chemoradiotherapy for stage II-III thoracic esophageal cancer in a single institution after 2000 -with a focus on comparison of three protocols.
BMC Cancer. 2015; 15:813 [PubMed] Free Access to Full Article Related Publications
METHODS: Between 2000 and 2012, 298 patients with stage II-III thoracic esophageal cancer underwent CRT. Patients in Group A received two cycles of cisplatin (CDDP) at 70 mg/m(2) (day 1 and 29) and 5-fluorouracil (5-FU) at 700 mg/m(2)/24 h (day 1-4 and 29-32) with radiotherapy (RT) of 60 Gy without a break. Patients in Group B received two cycles of CDDP at 40 mg/m(2) (day 1, 8, 36 and 43) and 5-FU at 400 mg/m(2)/24 h (day 1-5, 8-12, 36-40 and 43-47) with RT of 60 Gy with a 2-week break. Patients in Group C received two cycles of nedaplatin at 70 mg/m(2) (day 1 and 29) and 5-FU at 500 mg/m(2)/24 h (day 1-4 and 29-32) with RT of 60-70 Gy without a break. Differences in prognostic factors between the groups were analyzed by univariate and multivariate analyses.
RESULTS: The 5-year overall survival rates for patients in Group A, Group B and Group C were 52.4, 45.2 and 37.2%, respectively. The 5-year overall survival rates for patients in Stage II, Stage III (non-T4) and Stage III (T4) were 64.0, 40.1 and 22.5%, respectively. The 5-year overall survival rates for patients who received 1 cycle and 2 cycles of concomitant chemotherapy were 27.9 and 46.0%, respectively. In univariate analysis, stage, performance status and number of concomitant chemotherapy cycles were significant prognostic factors (p < 0.001, p = 0.008 and p < 0.001, respectively). In multivariate analysis, stage, protocol and number of concomitant chemotherapy cycles were significant factors (p < 0.001, p = 0.043 and p < 0.001, respectively).
CONCLUSIONS: The protocol used in Group A may be an effective protocol of CRT for esophageal cancer. It may be important to complete the scheduled concomitant chemotherapy with the appropriate intensity of CRT.
Long-Term Results of Concurrent Chemoradiotherapy for Advanced N2-3 Stage Nasopharyngeal Carcinoma.
PLoS One. 2015; 10(9):e0137383 [PubMed] Free Access to Full Article Related Publications
PATIENTS AND METHODS: Between April 2005 and December 2009, a total of 128 patients with N2-3 advanced NPC were retrospectively analyzed. Patients were treated with IMRT concurrent with 2 cycles of chemotherapy consisting of either nedaplatin plus paclitaxel (NP group, n = 67) or nedaplatin plus fluorouracil and paclitaxel (NFP group, n = 61). Two to four cycles of adjuvant chemotherapy were then administered every 21 days following concurrent chemoradiotherapy.
RESULTS: With a median follow-up of 60 months, the 5-year overall survival (OS), progression-free survival (PFS), local-regional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) for all patients were 81.4%, 71.5%, 87.8% and 82.0%, respectively. No significant difference in PFS (66.6% vs. 76.7%, P = 0.212) and LRRFS rates (89.0% vs. 86.3%, P = 0.664) was observed between the NP and NFP groups. The 5-year OS (75.4% vs. 88.5%, P = 0.046) and DMFS (75.1% vs. 89.0%, P = 0.042) rate were superior in the NFP group compared with the NP group. The NFP group had a higher incidence of grade 3-4 acute toxicities including bone marrow suppression (leukopenia: χ2 = 3.935, P = 0.047; anemia: χ2 = 9.760, P = 0.002; thrombocytopenia: χ2 = 8.821, P = 0.003), and both liver and renal dysfunction (χ2 = 5.206, P = 0.023) compared with the NP group. Late toxicities were moderate and no difference was observed between the two groups.
CONCLUSION: IMRT concurrent with nedaplatin-based chemotherapy is an advocated regimen for patients with advanced N2-3 stage NPC. Patients with advanced N2-3 stage may be better candidates for the NFP regimen although this regimen was associated with a high acute toxicity rate.
A Pooled Study on Combination of Gemcitabine and Nedaplatin for Treating Patients with Non-small Cell Lung Cancer.
Asian Pac J Cancer Prev. 2015; 16(14):5963-6 [PubMed] Related Publications
METHODS: Clinical studies evaluating the efficacy and safety of a combination of gemcitabine and nedaplatin with attention to response and safety for patients with non-small cell lung cancer were identified using a predefined search strategy. Pooled response rates for gemcitabine and nedaplatin were calculated.
RESULTS: In gemcitabine and nedaplatin based regimens, 4 clinical studies including 112 patients with non-small cell lung cancer were considered eligible for inclusion. The pooled analysis suggested that the pooled reponse rate was 40.2% (45/112). Main side effects included grade 3-4 neutropenia, thrombocytopenia, and anemia. Grade 3-4 nonhematological toxicity included nausea and vomiting, diarrhea, and hepatic dysfunction. There were no treatment-related deaths.
CONCLUSION: This evidence based analysis suggests that the combination of gemcitabine and nedaplatin is associated with good response rate and accepted toxicity for treating patients with non-small cell lung cancer.
Intensity-modulated radiation therapy versus three-dimensional conformal radiation therapy with concurrent nedaplatin-based chemotherapy after radical hysterectomy for uterine cervical cancer: comparison of outcomes, complications, and dose-volume histogram parameters.
Radiat Oncol. 2015; 10:180 [PubMed] Free Access to Full Article Related Publications
METHODS: Between March 2008 and February 2014, 62 patients were treated with concurrent nedaplatin-based chemotherapy and whole-pelvic external beam radiation therapy (RT). Of these patients, 32 (52%) received 3DCRT and 30 (48%) received IMRT.
RESULTS: The median follow-up periods were 40 months (range 2-74 months). The 3-year overall survival rate (OS), locoregional control rate (LRC) and progression-free survival rate (PFS) were 92, 95 and 92% in the IMRT group, and 85, 82 and 70% in the 3DCRT group, respectively. A comparison of OS, LRC and PFS showed no significant differences between IMRT and 3DCRT. The 3-year cumulative incidences of grade 2 or higher chronic gastrointestinal (GI) complications were significantly lower with IMRT compared to 3DCRT (3% vs. 45%, p < .02) and in patients with V40 of the small bowel loops of ≤340 mL compared to those with >340 mL (3% vs. 45%, p < .001). Patients treated with IMRT had a higher incidence of grade 3 acute hematologic complications (p < .05). V40 and V45 of the small bowel loops or bowel bag were predictive for development of both acute and chronic GI complications.
CONCLUSIONS: Our results suggest that IMRT for adjuvant treatment of cervical cancer is useful for decreasing GI complications without worsening outcomes.

METHODS: We assessed all patients with esophageal cancer of stages I-IV treated with definitive radiotherapy from June 2000 to March 2014. Between 2000 and 2011, ENI was used for all cases excluding high age cases. After Feb 2011, a prospective study about IFRT was started, and therefore IFRT was used since then for all cases. Concurrent chemotherapy regimen was nedaplatin (80 mg/m(2) at D1 and D29) and 5-fluorouracil (800 mg/m(2) at D1-4 and D29-32).
RESULTS: Of the 239 consecutive patients assessed (120 ENI vs. 119 IFRT), 59 patients (24.7%) had stage IV disease and all patients received at least one cycle of chemotherapy. The median follow-up time for survivors was 34.0 months. There were differences in 3-year local control (44.8% vs. 55.5%, p = 0.039), distant control (53.8% vs. 69.9%, p = 0.021) and overall survival (34.8% vs. 51.6%, p = 0.087) rates between ENI vs. IFRT, respectively. Patients treated with IFRT (8 %) demonstrated a significantly lower risk (p = 0.047) of high grade late toxicities than with ENI (16%). IFRT did not increase the risk of initially uninvolved or isolated nodal failures (27.5% in ENI and 13.4% in IFRT).
CONCLUSIONS: Nodal failure rates in clinically uninvolved nodal stations were not increased with IFRT when compared to ENI. IFRT also resulted in significantly decreased esophageal toxicity, suggesting that IFRT may allow for integration of concurrent systemic chemotherapy in a greater proportion of patients. Both tendencies of improved loco-regional progression-free survival and a significant increased overall survival rate favored the IFRT arm over the ENI arm in this study.
