BMC Surgery (2025) 25:47  \n[https://doi.org/10.1186/s12893-025-02778-z](https://doi.org/10.1186/s12893-025-02778-z)  \nBMC Surgery  \nREVIEW Open Access  \nRadiofrequency ablation combined  \nwith immunotherapy to treat hepatocellular carcinoma: a comprehensive review  \nGui-Lin Xie 1†, Zhi-Han Zhong2,3†, Tai-Wei Ye2,3* and Zun-Qiang Xiao2*  \nAbstract  \nBackground and aim Hepatocellular carcinoma (HCC) is a highly immunogenic tumor and the third leading cause of cancer-related deaths worldwide with an increasing incidence. Therefore, the combination of immunotherapy with other approaches, such as anti-angiogenic agents and local area therapy, has become a new strategy for HCC treatment.  \nMethods We searched PubMed and Web of Science and extracted publications relating to the radiofrequency ablation (RFA) and immunotherapy. The search terms were: “radiofrequency ablation”,“immunotherapy” and“hepatocellular carcinoma”, and manual searches of eligible articles from literature reference lists were performed. We then thoroughly reviewed the literature on ablation combined with immunotherapy for HCC, analyzed the relevant mechanism, and explored the safety and effectiveness of this form of combination therapy.  \nResults RFA combined with immunotherapy in HCC is reported to have good efficacy and controllable safety. On the one hand, RFA can induce the immunogenic substances including Ficolin-3, IL-1 and heat shock protein and regulate the immune cells by mediating the Th1/Th2 ratio, increasing Th17 cells, etc. On the other hand, RFA treatment can lead to tumor immune microenvironment reconstruction, increasing the proportion of functional T cells and upregulate PD-1 inT cells in distant tumors without RFA. This combined strategy has the ability to enhance the antitumor immune response through synergies, significantly reduce the risk of recurrence and improve survival. Conclusions RFA combined with immunotherapy yields a good synergistic effect: it can further strengthen antitumor response, delay distant tumor growth, reduce tumor recurrence and metastasis, providing new options for HCC systemic treatment.  \nKeywords Hepatocellular carcinoma, Radiofrequency ablation, Immunotherapy, Combination therapy  \n†Gui-Lin Xie and Zhi-Han Zhong contributed equally to this work.  \n*Correspondence: Tai-Wei Ye [ytaiweisur@163.com](ytaiweisur@163.com)[ ](ytaiweisur@163.com)Zun-Qiang Xiao [zqxiao@zcmu.edu.cn](zqxiao@zcmu.edu.cn)  \n1Department of Hepatobiliary Surgery, Affiliated Hospital of Shaoxing University, Shaoxing, Zhejiang, China  \n2General Surgery, Cancer Center, Department of Hepatobiliary & Pancreatic Surgery and Minimally Invasive Surgery, Affiliated People’s Hospital, Zhejiang Provincial People’s Hospital, Hangzhou Medical College, Hangzhou 310014, Zhejiang, China  \n3The Second School of Clinical Medicine, Zhejiang Chinese Medical University, Hangzhou 310053, China  \n© The Author(s) 2025.
