Brief Summary
Esophageal cancer is a prevalent digestive tract tumor, with around 400,000 new cases and 300,000 deaths globally each year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma (ESCC) 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 ESCC. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. The results of the Phase 1b trial evaluating adbelimumab monotherapy as a neoadjuvant treatment for locally advanced resectable ESCC demonstrated that patients receiving two cycles of neoadjuvant sequential surgery exhibited favorable safety profiles, with no adverse reactions of grade 3 or higher. The trial reported a major pathological response (MPR) rate of 24%, a pathological complete response (pCR) rate of 8%, a 2-year overall survival (OS) rate of 92%, and a 2-year recurrence-free survival (RFS) rate of 100%. The effectiveness of combining adbelizumab with chemotherapy and targeted therapy for locally advanced esophageal cancer is uncertain. This study aims to assess the efficacy and safety of using adbelizumab with chemotherapy and apatinib as neoadjuvant therapy for resectable ESCC.

Study Arms (1)
Adbelimumab, chemotherapy and apatinib
EXPERIMENTALPreoperative neoadjuvant therapy for 4 cycles. Radical surgery is performed 4-6 weeks after the last dose. Postoperative radiotherapy is determined according to the clinical situation and pathological stage of the patient. Adbelimumab can be aintained for a maximum of 1 year. During the study, patients were be followed until disease progression, withdrawal of informed consent, loss of follow-up, or death.
Interventions
Adbelimumab 1200mg Day 1; Albumin paclitaxel 260mg/m2, Day 1; carboplatin AUC=5, Day 1; Apatinib 250mg Po Day 2-4. Preoperative neoadjuvant therapy for 4 cycles, one cycle every 21 days.
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 IvorLewis (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.
Blood, Tumour will be Collected from participant. Fate of sample is Destruction after use. 20 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.
