Summary

China with high incidence of esophageal cancer, the number of new cases and deaths account for about 50% of the world every year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased. For patients with locally advanced esophageal cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients. According to the reports, the expression of PD-L1 in esophageal cancer was about 41.4%. Therefore, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of esophageal cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that serplulimab provided higher overall response rate for advanced esophageal cancer. However, in patients with locally advanced esophageal cancer, the efficacy of serplulimab combined with chemotherapy for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of silulimab combined with chemotherapy in the neoadjuvant therapy of resectable esophageal squamous cell carcinoma.

Conditions

• Esophageal Squamous Cell Carcinoma
• Neoadjuvant Therapy

Interventions

Type	Name	Description
COMBINATION_PRODUCT	Serplulimab, Albumin paclitaxel, carboplatin AUC=5, neoadjuvant therapy	Serplulimab 4.5mg/kg, IV, Day 1; Albumin paclitaxel 260mg/m2, Day 1; carboplatin AUC=5, Day 1; Preoperative neoadjuvant therapy for 3 cycles, one cycle every 21 days.
PROCEDURE	Esophagectomy	Prior to each surgical procedure, the department engaged in comprehensive discussions and deliberations to ascertain and establish the most suitable course of action. Minimally invasive Ivor-Lewis (intrathoracic anastomosis) or McKeown (neck anastomosis) esophagectomy, including two field extensive lymphadenectomies, was performed according to the tumor location. The resection length should be at least 5cm from the tumor origin according to prechemotherapy by endoscopy. The surgeries will be performed by surgeons with rich experience. Minimally invasive esophagectomy, can be performed using the da Vinci surgical robot, thoracoscope, or laparoscope, or by using an open approach, as judged appropriate by the surgeon.
OTHER	sample	Blood, Tumour will be Collected from participant. Fate of sample is Destruction after use. 5 ml of peripheral blood was collected the day before each of the immunotherapy sessions and after surgery. Tumour sample will be collected before neoadjuvant therapy and after surgery.
