Esophageal Squamous Cell Carcinoma Stage II, Esophageal Squamous Cell Carcinoma Stage III
Conditions
Brief summary
The goal of this clinical trial is to assess the 1-year DFS rate of toripalimab adjuvant therapy in participants with resected esophageal squamous cell carcinoma (ESCC) who achieved pCR. The main questions it aims to answer are: * The toripalimab adjuvant therapy could impove the 1-year DFS rate in participants with rescted ESCC who achieved pCR? * Is this treatment regimen safe? Researchers will compare toripalimab adjuvant therapy to clinical observation to see if toripalimab could improve the 1-year DFS rate. Participants will receive toripalimab 240 mg IV once every 3 weeks for one year or clinical observation.
Interventions
Participants will receive toripalimab 240 mg IV once every 3 weeks. Treatment continued until disease progression, death, unacceptable toxicity, investigator decision, withdrawal, or completion of 1 years of treatment, whichever occurred first.
