简要总结
The primary reason for recurrence of hepatocellular carcinoma after radiofrequency ablation (RFA) is the micro-metastatic lesion that has not been ablated and inactivated in the transitional area.Some clinical trials have confirmed that H101(recombinant human adenovirus type 5 injection) has selective oncolysis in a variety of solid tumors.However, there are no reports that H101 which is injected during surgery can improve the efficacy of RFA in liver cancer at present.Therefore,We used a multicenter prospective randomized controlled study as the main method to prospectively compare the short-term and long-term efficacy of RFA combined with H101 group and traditional RFA group in the treatment of small liver cancer (single lesion , diameter less than or equal to 3cm，to evaluate the value of RFA combined with H101 injection in reducing the postoperative recurrence rate of small hepatocellular carcinoma, and to provide a reliable evidence-based medical basis for the selection of treatment methods for small hepatocellular carcinoma.
详细描述
The primary reason for recurrence of hepatocellular carcinoma after radiofrequency ablation (RFA) is the micro-metastatic lesion that has not been ablated and inactivated in the transitional area.Oncolytic virus H101 is a genetically engineered adenovirus that lacks Elb 55ku protein.Some clinical trials have confirmed that H101 has selective oncolysis in a variety of solid tumors.Furthermore,research shows that the directly dissolving tumor activity of H101 enhanced obviously and activate the body's anti-tumor immune to induce the distal antitumor effect under the condition of mild high temperature (40 ℃ and 42 ℃).The transition zone of RFA can provide the appropriate mild high temperature.However, there are no reports that H101 which is injected during surgery can improve the efficacy of RFA in liver cancer at present.Therefore,We used a multicenter prospective randomized controlled study as the main method to prospectively compare the short-term and long-term efficacy of RFA combined with H101 group and traditional RFA group in the treatment of small liver cancer (single lesion , diameter less than or equal to 3cm，to evaluate the value of RFA combined with H101 injection in reducing the postoperative recurrence rate of small hepatocellular carcinoma, and to provide a reliable evidence-based medical basis for the selection of treatment methods for small hepatocellular carcinoma.

研究组 & 干预措施
RFA combined with H101 group
The experimental group was RFA combined H101.H101 has oncolysis in HCC after RFA and reduce tumor recurrence.
干预措施: H101 (Drug)
RFA combined with H101 group
The experimental group was RFA combined H101.H101 has oncolysis in HCC after RFA and reduce tumor recurrence.
干预措施: RFA (Procedure)
Conventional RFA group
The standard control group was the conventional RFA.Using RFA for the treatment of small HCC.The efficacy was compared with that of the experimental group combined with H101.
干预措施: RFA (Procedure)
结局指标
主要结局
Tumor-free survival
时间窗: two-years tumor-free survival.
Postoperative tumor-free survival is an evaluation of tumor recurrence and metastasis.It's also an evaluation of the efficacy of the experimental group
次要结局
- Overall survival(two-years overall survival.)
