About this trial
This study is a single-arm, prospective, phase II trial for patients with metastatic esophageal squamous cell carcinoma (ESCC) who received immunotherapy plus chemotherapy as the first-line treatment. The aim of the study is to determine if intervening with combined local therapy and immunotherapy and chemotherapy in patients with ESCC led to significant improvements in survival and disease control compared with historical data.
