evaluate the treatment with sintilimab injection plus endostar in hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma Non-resectable

Summary: it is a a single arm, observational clinical trial to evaluate the efficacy and safety of combination treatment with sintilimab injection plus endostar in untreated locally advanced or metastatic hepatocellular carcinoma.

for the first line treatment with untreated locally advanced or metastatic hepatocellular carcinoma, sintilimab injection plus endostar might be one of the treatment choices.
