Official title
Adjuvant Sintilimab for Locally Advanced Esophageal Squamous Cell Carcinoma: a Multi-Centre, Open-Label, Randomized, Controlled, Clinical Trial (HCHTOG2203)
Overview
No adjuvant treatment has been established for patients who remain at high risk for recurrence after neoadjuvant chemotherapy plus surgery and incidental pathologic lymph node metastasis following initial surgery for esophageal squamous cell carcinoma (ESCC).Controversy still exists regarding the role of adjuvant immunotherapy for ESCC patients who do not achieve pCR after neoadjuvant chemotherapy plus surgery and clinical T1-2 N0 patients with incidental pathologic lymph node metastasis following initial surgery. To investigate the outcomes of adjuvant Sintilimab in patients with locally advanced ESCC, we initiated this randomized controlled trial (RCT).
Interventions
- Drug Sintilimab
Patients in adjuvant arm receive 17 cycles of Sintilimab within 4 to 12 weeks after esophagectomy for ESCC. Sintilimab was administered intravenously at a dose of 200 mg over 30 minutes every 3 weeks.
Primary outcome measures
- Disease-free Survival (DFS) [Time frame: DFS is defined as the time from the date of randomization to the date of first recurrence (local, regional or distant) or death , assessed up to 36 months]
Eligibility criteria
Inclusion criteria

- No metastatic cervical lymph nodes.
- R0 resection is achieved by the minimally invasive esophagectomy (MIE) or open McKeown approach with total two-field lymph nodes dissection or three-field lymph nodes dissection.
