Combination Therapy of Microwave Ablation and Cellular Immunotherapy for Hepatocellular Carcinoma

Chinese PLA General Hospital40 enrolled

Overview

The study is to observe safety, survival effect and peripheral T-lymphocyte subsets of combination therapy with percutaneous microwave ablation (MWA) and adoptive immunotherapy in hepatocellular carcinoma(HCC).

HCC (D ≤5 cm, fewer than three tumors) patients were treated with radical MWA and 4-6 courses of immunotherapy with CIK every year. The immunotherapy were started at 2 weeks, 4 weeks, 6 weeks, 10 weeks, 14 weeks, 18 weeks and then every 12 weeks after MWA. Peripheral blood mononuclear cells were differentiated into phenotypically confirmed DCs and effector cells. DC-CIK and CTL were injected into the abdominal cavity. CIK was infused intravenously. The safety, survival effect and peripheral T-lymphocyte subsets of combination therapy group will be recorded and compared with those of MWA group.

Outcomes

Primary Outcomes

Cumulative survival rates were calculated by the Kaplan-Meier method, and comparison between MWA and combination treatment will be done by the log-rank test.

Time frame: up to 8 years

Secondary Outcomes

disease free survival rates were calculated by the Kaplan-Meier method, and comparison between MWA and combination treatment will be done by the log-rank test

Time frame: up to 8 years
