Salvage chemoradiation therapy for recurrence after radical surgery or palliative surgery in esophageal cancer patients: a prospective, multicenter clinical trial protocol
Background Currently, adjuvant therapy is not recommended for patients with thoracic esophageal squamous cell cancer (TESCC) after radical surgery, and a proportion of these patients go on to develop locoregional recurrence (LRR) within 2 years. Besides, there is no evidence for salvage chemoradiation therapy (CRT) in patients with residual tumor after esophagectomy (R1/R2 resection). In addition, factors like different failure patterns and relationship with normal organs influence the decision for salvage strategy. Here, we aimed to design a modularized salvage CRT strategy for patients without a chance of salvage surgery according to different failure patterns (including R1/R2 resection), and further evaluated its efficacy and safety. Methods Our study was designed as a one arm, multicenter, prospective clinical trial. All enrolled patients were stratified in a stepwise manner based on the nature of surgery (R0 or R1/2), recurrent lesion diameter, involved regions, and time-to-recurrence, and were further assigned to undergo either elective nodal irradiation or involved field irradiation. Then, radiation technique and dose prescription were modified according to the distance from the recurrent lesion to the thoracic stomach or intestine. Ultimately, four treatment plans were established. Discussion This prospective study provided high-level evidence for clinical salvage management in patients with TESCC who developed LRR after radical surgery or those who underwent R1/R2 resection. Trial registration Prospectively Registered. ClinicalTrials.govNCT03731442, Registered November 6, 2018..
