The Prospective Study of Sintilimab Combination With Chemotherapy Sequential Radiotherapy for Advanced Esophageal Squamous Cell Carcinoma
This is an investigator-initiated, single-arm, exploratory clinical study.The study population consisted of treatment naive advanced esophageal squamous cell carcinoma patients. The purpose of this study was to evaluate the efficacy and safety of immunotherapy combined with chemotherapy and residual lesions irradiation of esophageal squamous cell carcinoma.
• Diagnosed with Stage IV esophagus squamous cell carcinoma.
• Expected survival time ≥3 months
• Enrolled patients must have at least one measurable lesion conforming to the RECIST V1.1 definition.
• Physical fitness ECOG score of 0 or 1
• Organ function levels must meet the following requirements and meet the following standards:
⁃ A) Bone marrow function: absolute neutrophil count (ANC) ≥1.5×10\^9/L, platelet count ≥90×10\^9/L, hemoglobin ≥90 g/L; B) Liver function: Total bilirubin TBIL≤1.5×ULN (total bilirubin ≤3×ULN in Subjects with Gilbert's syndrome, liver cancer or liver metastasis), AST and ALT ≤2.5×ULN in patients without liver metastasis, AST and ALT ≤5.0×ULN in patients with liver metastasis; C) Renal function: Creatinine (Cr) ≤1.5×ULN, or creatinine clearance (Ccr) ≥50 mL/min (according to Cockcroft and Gault formula); D) Urine routine / 24-hour protein quantification: qualitative urine protein ≤1+ (if qualitative urine protein ≥2+, 24 hours \< 1g can be included); E) Cardiac function: left ventricular ejection fraction ≥50%; F) Coagulation function: International standardized ratio (INR) ≤1.5×ULN, and activated partial thrombin time (APTT) ≤1.5×ULN;
