Overview
Conduct a retrospective and prospective study to confirm the association between blood cells counts and the efficacy and safety in immunochemotherapy in patients with advanced esophageal cancer.
Description
Studies have already demonstrated the feasibility of prognostic role of protein biomarkers change during the treatment trajectory of patients in several carcinoma,However, no study focused on the value of trajectory analysis of blood cells counts of Immunochemotherapy in patients with advanced esophageal cancer.
The investigators plan to analyze the dynamic change of blood cells counts longitudinally from preoperation to long term follow-up in advanced esophageal cancer and predict the efficacy and safety of immunochemotherapy.
