Study Details

Study Description

Brief Summary

The purpose of this study is to analyze esophageal cancer patients who underwent neoadjuvant immunotherapy with chemotherapy followed by esophagectomy to determine whether additional adjuvant therapy is associated with improved survival outcomes.

Condition or Disease	Intervention/Treatment	Phase
Esophageal Squamous Cell Carcinoma Neoadjuvant Chemoimmunotherapy Adjuvant Therapy	Drug: Tislelizumab	Phase 2

Detailed Description

Eligiled patients with pathologically confirmed thoracic esophageal squamous cell carcinoma and at clinical T1b-3N1-3M0 or T3N0M0 according to the eighth edition of American Joint Committee on Cancer staging will be allocated to neoadjuvant immunotherapy (tislelizumab 200mg d1, q3w × 2 cycles ) and chemotherapy (nad-paclitaxel 260 mg/m2 d1 + carboplatin AUC = 5 d1, q3w × 2 cycles) treatment. Patients with resected (R0) were assigned to receive tislelizumab ( at a dose of 200 mg every 3 weeks for 30 weeks) in pCR patients or adjuvant immunotherapy and chemothearpy for two cycles, and then tislelizumab ( at a dose of 200 mg every 3 weeks for 24 weeks) in non-pCR patients.The primary endpoint for this study is 2-year disease-free survival (DFS) in non-pCR patients.The secondary endpoints include pCR rate, major pathological response (MPR) rate, 2-year DFS in pCR patients, R0 resection rate, adverse events, and overall survival (OS).

Outcome Measures

Primary Outcome Measures

2-year disease-free survival in non-pCR patients [Disease free survival time for recurrence or death within 2 years of surgery]
The time from the first day of surgery to the first occurrence of local or distant recurrence and metastasis or death from any cause in non-pCR patients

Secondary Outcome Measures

pCR rate [4 weeks after surgery]
Pathological complete response (pCR) rate of all patients
major pathological response [4 weeks after surgery]
MPR was defined as the presence of viable tumor cells≤10% in the resected tumor specimen
2-year DFS in pCR patients [Disease free survival time for recurrence or death within 2 years of surgery]
The time from the first day of surgery to the first occurrence of local or distant recurrence and metastasis or death from any cause in pCR patients
R0 resection rate [4 weeks after surgery]
No vital tumor is presented at the proximal, distal, or circumferential resection margin, then it is considered R0 resection
adverse events [Up to 100 months]
Safety will be evaluated for all treated patients using CTCAE V 5.0.
overall survival [Up to 5 years]
The date of death of any causes since the date of randomization.
