CMISG1701: a multicenter prospective randomized phase III clinical trial comparing neoadjuvant chemoradiotherapy to neoadjuvant chemotherapy followed by minimally invasive esophagectomy in patients with locally advanced resectable esophageal squamous cell carcinoma (cT3-4aN0-1M0) (NCT03001596).

ABSTRACT: Neoadjuvant chemoradiation is not recommended as an approach for treatment of esophageal squamous cell carcinoma due to its significant postoperative mortality. However, it is assumed the combination of neoadjuvant chemoradiation with minimally invasive esophagectomy (MIE) may reduce postoperative mortality, which can revive preoperative chemoradiation. No randomized controlled studies comparing neoadjuvant chemoradiation plus MIE with neoadjuvant chemotherapy plus MIE have been performed so far. The present trial is initiated to obtain valid information whether neoadjuvant chemoradiation plus MIE yields better survival without worse postoperative morbidity and mortality in the treatment of locally advanced resectable esophageal squamous cell carcinoma(cT3-4aN0-1M0).CMISG1701 is a multicenter, prospective, randomized, phase III clinical trial, investigating the safety and efficacy of neoadjuvant chemoradiation plus MIE compared with neoadjuvant chemotherapy plus MIE. Patients with locally advanced resectable esophageal squamous cell carcinoma (cT3-4aN0-1M0) are eligible for the study. A total of 264 patients are randomly assigned to neoadjuvant chemoradiation (arm A) or neoadjuvant chemotherapy (arm B) with a 1:1 allocation ratio. The primary outcome is overall survival assessed with a minimum follow-up of 36 months. Secondary outcomes are progression-free survival, recurrence-free survival, postoperative pathologic stage, treatment-related complications, postoperative mortality as well as quality of life.The objective of this trial is to identify the superior protocol with regard to patient survival, treatment morbidity/mortality and quality of life between neoadjuvant chemoradiation plus MIE and neoadjuvant chemotherapy plus MIE.NCT03001596 (December 17, 2016).

Project description:BackgroundConcurrent chemoradiotherapy followed by adjuvant chemotherapy (CCRT-AC) is currently recommended as the standard treatment for locally advanced nasopharyngeal carcinoma (LA-NPC). Neoadjuvant chemotherapy followed by concurrent chemoradiotherapy (NAC-CCRT) is an alternative strategy for decreasing tumor size and controlling micrometastases before main treatment. The aim of this study was to investigate and compare survival outcomes between LA-NPC patients treated with CCRT-AC and those treated with NAC-CCRT.MethodsThis retrospective cohort study included consecutive histologically confirmed LA-NPC patients that were treated with NAC-CCRT or CCRT-AC at Siriraj Hospital during the March 2010 to October 2014 study period. CCRT in both protocols consisted of 3-week cycles of cisplatin 100 mg/m2 with concurrent radiotherapy. Either NAC or AC consisted of 3-week cycles of cisplatin on day 1 and fluorouracil/leucovorin on days 1-4 for a maximum three cycles. The primary endpoint was 5-year overall survival (OS). Flexible parametric survival analysis was used, because the proportional hazards assumption of Cox regression was violated.ResultsOf the 266 LA-NPC patients that received treatment during the study period, 79 received NAC-CCRT and 187 received CCRT-AC. Median follow-up was 37 months. Significantly more patients with advanced clinical stage (stage IVA-IVB) received NAC-CCRT (86% in NAC-CCRT vs. 29% in CCRT-AC; p < 0.001). Compared to CCRT-AC in crude analysis, 3-year and 5-year OS of NAC-CCRT were 72% vs. 86% and 62% vs. 75% respectively (p = 0.059). Interestingly, the 3-year and 5-year post-estimation adjusted OS was 84% and 74% for NAC-CCRT and 81% and 70% for CCRT-AC, respectively (HR: 0.83, 95% confidence interval (CI): 0.45-1.56; p = 0.571). Also, adjusted analysis of distant-metastasis survival, NAC-CCRT showed HR was 0.79 (95% CI:0.37-1.72, p = 0.557). Conversely, adjusted analysis of locoregional relapse (LLR)-free survival revealed NAC-CCRT to have a significantly higher risk of LRR (HR: 2.18, 95% CI: 0.98-4.87; p = 0.057).ConclusionsThe results suggested that prognosis in the NAC-CCRT treated patients was not superior to that of the CCRT-AC treated individuals. In patients that receive neoadjuvant chemotherapy, locoregional relapse should be of concern. High-risk distant metastasis patients (N3 stage) that could achieve survival advantage from NAC-CCRT is an interesting and important topic for further study.

Project description:ImportanceSafety and efficacy of neoadjuvant chemoradiotherapy (nCRT) vs neoadjuvant chemotherapy (nCT) for treatment of locally advanced esophageal squamous cell carcinoma (ESCC) remain uncertain given lack of high-level clinical evidence.ObjectiveTo compare safety and long-term survival of nCRT followed by minimally invasive esophagectomy (MIE) with that of nCT followed by MIE for patients with locally advanced ESCC.Design, setting, and participantsA prospective, multicenter, open-label, randomized clinical trial that compared safety and efficacy of nCRT vs nCT followed by MIE for patients with locally advanced ESCC. From January 1, 2017, to December 31, 2018, 264 patients with ESCC of clinical stages from cT3 to T4aN0 to 1M0 were enrolled. Analysis was performed on an intention-to-treat basis from January 1, 2017, to August 30, 2020.InterventionsEligible patients were randomized to the nCRT group (n = 132) or the nCT group (n = 132) by a computer-generated random system. The chemotherapy, based on paclitaxel and cisplatin, was administered to both groups, while 40 Gy of concurrent radiotherapy was added for the nCRT group. At about 6 weeks after neoadjuvant therapy, MIE via thoracoscopy and laparoscopy was performed for the patients in both groups.Main outcomes and measuresThe primary outcome was 3-year overall survival. Secondary outcomes included postoperative complications, mortality, postoperative pathologic outcome, recurrence-free survival time, and quality of life.ResultsAmong 264 patients (226 men [85.6%]; mean [SD] age, 61.4 [6.8] years), postoperative morbidity was 47.4% in the nCRT group (54 of 114) and 42.6% in the nCT group (46 of 108), with no significant difference between groups (difference, 4.8%; 95% CI, -8.2% to 17.5%; P = .48). Distribution of the severity of complications was similar between the 2 groups based on Clavien-Dindo classification. The 90-day perioperative mortality rate was 3.5% for the nCRT group (4 of 114) and 2.8% for the nCT group (3 of 108) (P = .94). The R0 resection rates were similar between groups (109 of 112 [97.3%] vs 100 of 104 [96.2%]; P = .92). However, patients in the nCRT group had a higher pathologic complete response (residual tumor, 0%) rate (40 of 112 [35.7%] vs 4 of 104 [3.8%]; P < .001) and a higher rate of negative lymph nodes (ypN0, 74 of 112 [66.1%] vs 48 of 104 [46.2%]; P = .03) than those in the nCT group. One-year overall survival using intention-to-treat analysis was 87.1% in the nCRT group (115 of 132) and 82.6% in the nCT group (109 of 132) (P = .30). Furthermore, deaths caused by tumor progression or recurrence were significantly less in the nCRT group than in the nCT group (9 of 132 [6.8%] vs 19 of 132 [14.4%]; P = .046); however, deaths from nontumor causes were similar (8 of 132 [6.1%] vs 4 of 132 [3.0%]; P = .24).Conclusions and relevanceInitial results of the trial showed that nCRT followed by MIE has similar safety to and better histopathologic outcome than nCT followed by MIE for treatment of locally advanced ESCC.Trial registrationClinicalTrials.gov Identifier: NCT03001596.

Project description:Neoadjuvant chemoradiotherapy followed by surgery is the primary treatment option for patients with locally advanced esophageal cancer. This multicenter phase I trial examined intratumoral injection of TNFerade biologic, an adenoviral vector that expresses the human tumor necrosis factor-? gene, with chemoradiotherapy in locally advanced esophageal cancer.To assess pathologic complete response (pCR), time to disease progression, progression-free survival, survival, and safety and tolerance in patients treated with preoperative chemoradiation combined with endoscopy or EUS-guided intratumoral injection of TNFerade biologic.Five weekly injections of TNFerade biologic, dose-escalated logarithmically from 4 × 10(8) to 4 × 10(11) particle units (PU), were given in combination with cisplatin 75 mg/m(2) and intravenous 5-fluorouracil 1000 mg/m(2)/d for 96 hours on days 1 and 29, and concurrent radiation therapy to 45 Gy. Surgery was performed 9 to 15 weeks after treatment.U.S. multicenter study.Patients with stage II and III esophageal cancer were enrolled.Primary outcome measures were safety, feasibility, tolerability, and rate of pCR. Secondary outcome measures were overall survival (OS) and disease-free survival.Twenty-four patients with a median age of 61 years were enrolled; 88% of the patients were men, 21% were stage II, and 79% were stage III. Six (29%) had a pCR, observed among 21 patients (20 who underwent esophagectomy and 1 at autopsy). Dose-limiting toxicities were not observed. The most frequent potentially related adverse events were fatigue (54%), fever (38%), nausea (29%), vomiting (21%), esophagitis (21%), and chills (21%). At the top dose of 4 × 10(11) PU, thromboembolic events developed in 5 of 8 patients. The median OS was 47.8 months. The 3- and 5-year OS rates and disease-free survival rates were 54% and 41% and 38% and 38%, respectively.We included primarily adenocarcinoma.Preoperative TNFerade, in combination with chemoradiotherapy, is active and safe at doses up to 4 × 10(10) PU and is associated with long survival. This regimen warrants additional studies.

Project description:Importance:Patients with borderline-resectable pancreatic ductal adenocarcinoma have historically poor outcomes with surgery followed by adjuvant chemotherapy. Evaluation of a total neoadjuvant approach with highly active therapy is warranted. Objective:To evaluate the margin-negative (R0) resection rate in borderline-resectable pancreatic ductal adenocarcinoma after neoadjuvant FOLFIRINOX (fluorouracil, irinotecan, and oxaliplatin) therapy and individualized chemoradiotherapy. Design, Setting, and Participants:A single-arm, phase 2 clinical trial was conducted at a large academic hospital with expertise in pancreatic surgery from August 3, 2012, through August 31, 2016, among 48 patients with newly diagnosed, previously untreated, localized pancreatic cancer determined to be borderline resectable by multidisciplinary review, who had Eastern Cooperative Oncology Group performance status 0 or 1 and adequate hematologic, renal, and hepatic function. Median follow-up for the analysis was 18.0 months among the 30 patients still alive at study completion. Interventions:Patients received FOLFIRINOX for 8 cycles. Upon restaging, patients with resolution of vascular involvement received short-course chemoradiotherapy (5 Gy × 5 with protons) with capecitabine. Patients with persistent vascular involvement received long-course chemoradiotherapy with fluorouracil or capecitabine. Main Outcomes and Measures:The primary outcome was R0 resection rate; secondary outcomes were median progression-free survival (PFS) and median overall survival (OS). Results:Of the 48 eligible patients, 27 were men and 21 were women, with a median age of 62 years (range, 46-74 years). Of the 43 patients who planned to receive 8 preoperative cycles of chemotherapy, 34 (79%) were able to complete all cycles. Twenty-seven patients (56%) had short-course chemoradiotherapy, while 17 patients (35%) had long-course chemoradiotherapy. R0 resection was achieved in 31 of the 48 eligible patients (65%; 95% CI, 49%-78%). Among the 32 patients who underwent resection, the R0 resection rate was 97% (n = 31). Median PFS among all eligible patients was 14.7 months (95% CI, 10.5 to not reached), with 2-year PFS of 43%; median OS was 37.7 months (95% CI, 19.4 to not reached), with 2-year OS of 56%. Among patients who underwent resection, median PFS was 48.6 months (95% CI, 14.4 to not reached) and median OS has not been reached, with a 2-year PFS of 55% and a 2-year OS of 72%. Conclusions and Relevance:Preoperative FOLFIRINOX followed by individualized chemoradiotherapy in borderline resectable pancreatic cancer results in high rates of R0 resection and prolonged median PFS and median OS, supporting ongoing phase 3 trials.

Project description:BackgroundFor patients with esophageal adenocarcinoma or cancer of the gastroesophageal junction, radical esophagectomy with 2-field lymphadenectomy is the cornerstone of the multimodality treatment with curative intent. Both conventional minimally invasive esophagectomy (MIE) and robot assisted minimally invasive esophagectomy (RAMIE) were shown to be superior compared to open transthoracic esophagectomy considering postoperative complications. However, no randomized comparison exists between MIE and RAMIE in the Western World for patients with esophageal adenocarcinoma.MethodsThis is an investigator-initiated and investigator-driven multicenter randomized controlled parallel-group superiority trial. All adult patients (age ≥ 18 and ≤ 90 years) with histologically proven, surgically resectable (cT1-4a, N0-3, M0) esophageal adenocarcinoma of the intrathoracic esophagus or adenocarcinoma of the gastroesophageal junction and with European Clinical Oncology Group performance status 0, 1 or 2 will be assessed for eligibility and included after obtaining informed consent. Patients (n = 218) with resectable esophageal adenocarcinoma of the intrathoracic esophagus or adenocarcinoma of the gastroesophageal junction are randomized to either RAMIE (n = 109) or MIE (n = 109). The primary outcome of this study is the total number of resected abdominal and mediastinal lymph nodes specified per lymph node station.ConclusionThis is the first randomized controlled trial designed to compare RAMIE to MIE as surgical treatment for resectable esophageal adenocarcinoma or adenocarcinoma of the gastroesophageal junction in the Western World. The hypothesis of the proposed study is that RAMIE will result in a higher abdominal and mediastinal lymph node yield specified per station compared to conventional MIE. Short-term results and the primary endpoint (total number of resected abdominal and mediastinal lymph nodes per lymph node station) will be analyzed and published after discharge of the last randomized patient within this trial.Trial registrationClinicalTrials.gov Identifier: NCT04306458 .
