The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently.
On this basis, the investigators intend to conduct a prospective, multicenter phase III clinical trial to assess whether radiotherapy with concurrent chemotherapy and immunotherapy could further improve the survival of patients with metastatic esophageal cancer.
Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.

The study is an interventional phase II clinical trial aiming to evaluate the efficacy and safety of KN046, a PD-L1 and CTLA-4 bispecific antibody, in combination with regorafenib or apatinib for microsatellite instability-high digestive system cancers resistant to PD-1/PD-L1 blockade. KN046 plus regorafenib will be given for patients with colorectal cancers, and KN046 plus apatinib will be given for patients with gastric cancers (including esophageal-gastric junction cancers) and other kinds of digestive system cancers.

The purpose of this study is to evaluate how well fuzoparib in combination with camrelizumab and temozolomide works in treating patients with advanced, metastatic melanoma with the homologous recombination (HR) pathway gene mutation / alteration.
