Objective

2

To observe the clinical efficacy of Jiawei Xiaochaihutang combined with microwave ablation （MWA） in the treatment of primary hepatocellular carcinoma （HCC） and its influence on tumor microenvironment.

Method

2

A total of 128 patients were randomly divided into control group （64 cases： 2 cases of dropout，2 cases of elimination，and 60 cases of completion） and observation group （64 cases： 3 cases of dropout，2 cases of elimination，and 59 cases of completion）. Both groups were given comprehensive treatment after MWA surgery. Patients in control group took Biejiajian Wan orally （3 g/time，3 times/d）， and those in observation group took Jiawei Xiaochaihutang （1 dose/d）. The treatment lasted for 3 consecutive months. The size of solid tumor before and after treatment was evaluated to record the progression-free survival （PFS）. The alpha-fetoprotein-L13 （AFP-L3），des-γ-carboxy prothrombin （DCP），Golgi protein 73 （GP73），tumor necrosis factor-

In addition， the incidence of side effects of grade Ⅲ and above was compared.

Result

2

The total effective rate of solid tumor in observation group was 91.53% （54/59），higher than that （76.67%， 46/60） in control group（

Conclusion

2

Consolidation treatment of HCC after MWA surgery with Jiawei Xiaochaihutang relieved symptoms and side effects，improved PS and liver function，regulated tumor microenvironment，inhibited tumor markers and prolonged survival time. The clinical effect was better than that of Biejia decoction pill， and thus it was worthy of clinical use.
