Phase I evaluation of TNFerade biologic plus chemoradiotherapy before esophagectomy for locally advanced resectable esophageal cancer.

ABSTRACT: 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:PURPOSE:This trial aimed to assess the efficacy and safety of the paclitaxel plus fluorouracil regimen versus the cisplatin plus fluorouracil regimen in definitive concurrent chemoradiotherapy (dCRT) in patients with locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS:Patients with locally advanced ESCC were enrolled and randomly assigned to either the paclitaxel plus fluorouracil group or the cisplatin plus fluorouracil group. The patients in the paclitaxel plus fluorouracil group were treated with paclitaxel and fluorouracil one cycle per week in dCRT for five cycles followed by paclitaxel and fluorouracil one cycle per month in consolidation chemotherapy for two cycles. The patients in the cisplatin/5-fluorouracil group were treated with cisplatin and fluorouracil one cycle per month in dCRT for two cycles followed by two cycles in consolidation chemotherapy. The radiotherapy dose was 61.2 Gy delivered in 34 fractions. The primary end point was 3-year overall survival (OS). RESULTS:Four hundred thirty-six patients with ESCC in six centers were recruited at a 1:1 ratio between April 2012 and July 2015. The median follow-up of the surviving patients was 48.7 months (interquartile range, 42.6-60.9). The 3-year OS was 55.4% in the paclitaxel plus fluorouracil group and 51.8% in the cisplatin plus fluorouracil group (hazard ratio, 0.905 [95% CI, 0.698 to 1.172]; P = .448). The 3-year progression-free survival was also not significantly different between the paclitaxel plus fluorouracil group and the cisplatin plus fluorouracil group (43.7% v 45.5%, respectively; hazard ratio, 0.973 [95% CI, 0.762 to 1.243]; P = .828). Compared with the cisplatin plus fluorouracil group, the paclitaxel plus fluorouracil group had significantly lower incidences of acute grade 3 or higher anemia, thrombocytopenia, anorexia, nausea, vomiting, and fatigue (P < .05), but higher incidences of acute grade 3 or higher leukopenia, radiation dermatitis, and radiation pneumonitis (P < .05). CONCLUSION:The paclitaxel plus fluorouracil regimen did not significantly prolong the OS compared with the standard cisplatin plus fluorouracil regimen in dCRT in patients with locally advanced ESCC.

Project description:BackgroundThis study aims to investigate the efficacy and safety of postoperative intensity-modulated radiotherapy (IMRT) covering partial regional lymph node areas combined with chemotherapy for locally advanced thoracic esophageal squamous cell carcinoma patients.MethodsThis was a single-center, single-arm phase II clinical trial that began in 2014. Patients who underwent radical transthoracic resection within 3 months and were histologically confirmed esophageal squamous cell carcinoma (pT3-4 or N+, M0 determined according to AJCC Guidelines, Edition 7) were recruited. Postoperative radiotherapy was performed with a total dose of 50.4Gy in 28 fractions using IMRT. Clinical target volumes (CTVs) included tumor bed, anastomosis, bilateral supraclavicular region, and superior mediastinal lymph nodes. Synchronous chemotherapy for 2 cycles (paclitaxel 150mg/m2, day1; Cisplatin 25mg/m2, day1-3; every 4 weeks), followed by 2 cycles of consolidation chemotherapy with the same regimen. The primary endpoint was the 2-year local control rate, and the secondary endpoints were overall survival (OS) and adverse events (AEs).ResultsA total of 75 eligible patients were included from 2014 to 2017. The 2-year LRFS rate, as the primary endpoint, was 73.3%. The 1-year and 3-year OS rates were 88.0% and 68.0%, respectively. Local recurrence occurred in 13/75 (17.4%) patients, of which 2.7% (2/75) were extra-target lymph nodes. Grade 4 adverse events reported in this study included 10 cases (13.3%) of neutropenia, 1 case (1.3%) of anemia, and 2 cases (2.7%) of thrombocytopenia, without toxic-related deaths. Almost all (96%) patients completed the entire postoperative radiotherapy course, and 62 (82.7%) patients completed at least 2 cycles of chemotherapy.ConclusionPostoperative IMRT (clinical target volume including tumor bed, anastomosis, bilateral supraclavicular region, and superior mediastinal lymph nodes) combined with synchronous chemotherapy in patients with locally advanced thoracic esophageal squamous cell carcinoma was well tolerated, with a high local control rate and a low probability of recurrence outside the irradiation field.Clinical trial registrationhttps://clinicaltrials.gov/ChiCTR1900022689.

Project description:Concurrent chemoradiotherapy is a standard modality for locally advanced esophageal squamous cell carcinoma (ESCC) patients. Cisplatin combined with 5-fluorouracil continuous infusion (PF) remains the standard concurrent chemotherapy regimen. However, radiotherapy concurrent with PF showed a high incidence of severe side effects. Paclitaxel showed a promising radiosensitivity enhancement in the treatment of esophageal carcinoma in both vitro and vivo studies. The ESO-Shanghai 1 trial examines the hypothesis that paclitaxel plus 5-fluorouracil (TF) concurrent with radiotherapy has better overall survival and lower toxicity for patients with local advanced ESCC.Four hundred thirty-six ESCC patients presenting with stage IIa to IVa will be enrolled in a prospective multicenter randomized phase 3 study. Patients will be randomized to either concurrent chemoradiotherapy with PF (cisplatin 25 mg/m2/d, d1-3, plus 5-fluorouracil 1800 mg/m2, continuous infusion for 72 h) once every 4 weeks for 2 cycles followed by consolidation chemotherapy for 2 cycles or concurrent chemoradiotherapy with weekly TF (5-fluorouracil 300 mg/m2, continuous infusion for 96 h plus paclitaxel 50 mg/m2, d1) for 5 weeks followed by consolidation chemotherapy (5-fluorouracil 1800 mg/m2, continuous infusion for 72 h, plus paclitaxel 175 mg/m2 d1) once every 4 weeks for 2 cycles. The radiotherapy dose is 61.2 Gy delivered in 34 fractions to the primary tumor including lymph nodes. The primary end-point is the 3-yr overall survival analyzed by intention to treat. The secondary endpoints are disease progression-free survival, local progression-free survival, and number and grade of participants with adverse events.The aim of this phase 3 study is to determine whether the TF regimen could replace the standard PF regimen for inoperable ESCC patients. An overall survival benefit of 12% at 3 years should be expected in the TF group to achieve this goal.ClinicalTrials.gov Identifier: NCT01591135 . Registered 18 April 2012.
