A Single-arm, Open, Single-center Exploratory Study of Adebrelimab (SHR-1316) in Combination With Chemotherapy for the Perioperative Treatment of Locally Advanced Resectable Esophageal Squamous Carcinoma

All subjects were given 3 cycles of neoadjuvant therapy with adebrelimab (1200 mg D1, IV, Q3W)+Nab-paclitaxel(250 mg/m2 D1，IV，Q3W)+Cisplatin(75 mg/m2 D1，IV，Q3W) preoperatively. Within 4-8 weeks of completion of neoadjuvant therapy, all subjects who were suitable for surgery underwent radical surgery, and patients who underwent radical esophageal cancer with R0 resection were given adebrelimab monotherapy postoperatively until disease recurrence or metastasis, toxicity intolerance, initiation of a new antitumor therapy, subject-initiated request to withdraw from the study, and subject's judgement that the subject needed to be withdrawn from the study. The maximum duration of adebrelimab in the adjuvant phase is 16 cycles.
