umbilical cord blood derived mak immune cells combined with standard second-line treatments for hepatobiliary and pancreatic malignancies

Conditions: Stage IV Pancreatic Cancer; Hepatocellular Carcinoma , Cholangiocarcinoma

Summary: to evaluate the safety of mak immune cells derived from umbilical cord blood combined with second-line treatments for hepatobiliary and pancreatic malignancies.and to investigate the initial efficacy of mak immune cells derived from umbilical cord blood combined with second-line treatments for hepatobiliary and pancreatic malignancies.
