There is no standard recommendation for the treatment of advanced esophageal squamous cell cancer after chemotherapy failure. Anrotinib combined with triplizumab have showed synergistic effect in the tumor treatment, and they have demonstrated robust antitumor activity in the first-line treatment of advanced NSCLC with negative driving gene. However, there is no related report on the efficacy in the treatment of advanced esophageal squamous cell carcinoma. The aim of this study is to investigate the efficacy and safety of anrotenib plus toripalimab in the treatment of advanced esophageal squamous cell carcinoma. In addition, the investigators will explore the possible mechanisms of anrotinib combined with toripalimab in advanced esophageal squamous cell carcinoma, and screen out biomarkers that can predict the efficacy of combination therapy.
