Highlights |
• | Our meta-analysis showed combining cellular immunotherapy in advanced HCC could increase the complete response rate, and thereafter extend the progression-free and overall survival rate. |
• | Subgroup analysis suggested that combining use of CIK and DC or using CIK alone could provide the benefit in survival outcome. |
Summary |
Background |
The efficacy of cellular immunotherapy in advanced hepatocellular carcinoma (HCC) was controversial. This study was conducted to compare the effectiveness of combining cellular immunotherapy with that of incurable treatment alone.
Methods |
The Ovid Medline, Embase, Cochrane Library and Pubmed were systematically searched due to January 8th 2020. The keywords include “immunotherapy”, “HCC” and study type. Treatment response was evaluated and progression-free survival (PFS) and overall survival (OS) were calculated using hazard ratio (HR) and 95% confidence interval (CI).
Results |
A total of 19 studies with 1275 patients were included in the meta-analysis. The median complete response rate (CR) was 19% in combining cellular immunotherapy comparing to 9% in the control group (RR=0.55, P=0.003). No significant difference was found in partial response and stable disease (RR=1.06 and 0.78, P>0.05, respectively). The progression disease rate was higher in the non-cellular immunotherapy group (31%) compared to the cellular immunotherapy group (RR=2.20, P=0.002). Patients treating with cellular immunotherapy had a better OS and PFS compared to those without cellular immunotherapy (HR=0.52 and 0.63, P<0.001). In the subgroup analysis, the only CIK infusion therapy and combined DC with CIK perfusion therapy patients had a better OS (HR=0.52 and 0.49, P<0.001 and P=0.002, respectively).
Conclusion |
Our results suggested that combining use of cellular immunotherapy in advanced HCC could increase the complete response rate, and thereafter extend the progression-free and overall survival rate. Subgroup analysis suggested that combining use of CIK and DC or using CIK alone could provide the benefit in survival outcome.
