TC Plus PD-1 Inhibitors Combined With Anlotinib for Advanced Advanced Esophageal Cancer

Paclitaxel and Carboplatin Plus PD-1 Inhibitors Combined With Anlotinib for Advanced Esophageal Cancer(ESCC)

A Controlled Clinical Study of TC/PD-1 Inhibitors Combined With anlotinib as First-line Treatment for Advanced ESCC

The incidence rate of esophageal cancer is high in China and mainly squamous cell carcinoma. In recent years, although the level of surgery, radiotherapy and chemotherapy of esophageal cancer has improved, and studies have confirmed the role of anlotinib and PD-1 mAb in the posterior line treatment of esophageal squamous cell carcinoma, the prognosis of esophageal cancer is still not ideal. How to expand the clinical benefits of immunotherapy in esophageal cancer has become a research hotspot. Recent studies have shown that PD-1 mAb combined with other therapies with different mechanisms can improve the efficacy of immunotherapy. In the impawer150 study, platinum containing dual drug chemotherapy plus anti angiogenesis therapy combined with immunotherapy showed statistically and clinically significant PFS benefits in the first-line treatment of advanced non-small-cell lung cancer, which provides a new choice for the first-line treatment of advanced non-small-cell lung cancer. So far, there is no report on the first-line treatment of advanced esophageal squamous cell carcinoma with platinum containing dual drug chemotherapy plus anti angiogenesis drugs combined with immunotherapy. The purpose of this study is to evaluate the efficacy of cisplatin plus cisplatin in the treatment of advanced esophageal cancer.
