Brief Summary

Comparative analysis of patients with resectable locally advanced esophageal squamous cell carcinoma treated with neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy combined sintilimab versus neoadjuvant chemoradiotherapy.

Detailed Description

The research process is divided into three stages: firstly, the stage of screening period for 14 days. Qualified subjects will enter the treatment period after completion of screening examination and evaluation. And then, the stage of treatment period: Experimental group (group A) received sintilimab combined with neoadjuvant chemotherapy regimen: preoperative neoadjuvant, sintilimab (D1 administration) combined with chemotherapy (TP regimen: albumin-paclitaxel + carboplatin, D1 administration) for 2 cycles. Every 3 weeks, there was a dosing cycle (Q3W). The experimental group (group B) received neoadjuvant sintilimab combined concurrent chemoradiotherapy: preoperative sintilimab (D1 administration) combined with neoadjuvant concurrent chemoradiotherapy. Chemotherapy regimen: TP regimen: albumin-paclitaxel + carboplatin, D1 administration, 2 cycles. Every 3 weeks, there was a dosing cycle (Q3W). Radiotherapy regimen: according to IMRT treatment plan, the total dose was 41.4Gy, divided into 23 times, 5 days a week. And the control group (group C) received neoadjuvant chemoradiotherapy and the regimen was similar with group B. Surgery was performed 6-8 weeks after completion of neoadjuvant therapy. If the patient without vital tumor cells in primary and lymph nodes after surgery, they only need regular follow-up visit. If the patients with non-pCR resected, those patients need to receive adjuvant immunotherapy. And if the patients with non-R0 resected, the regimen of those patients need to carefully decide based on multidisciplinary team discussed. Lastly, the stage of postoperative assistance, the researchers selected postoperative treatment according to the guidelines for the diagnosis and treatment of esophageal cancer. Patients were followed up for efficacy and safety within 90 days after surgery, once every 3 months for 2 years and once every 6 months for 2-5 years.
