Background: Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors globally, characterized by high incidence and mortality rates. Radiofrequency ablation (RFA) is a widely adopted primary ablative therapy for HCC, playing a pivotal role in the management of small HCC and unresectable lesions. However, a subset of HCC patients experiences rapid tumor recurrence and progression following RFA. Objective: This review aims to summarize the mechanisms underlying rapid tumor progression after RFA for hepatocellular carcinoma, thereby providing a theoretical foundation and future research directions for preventing post-ablation recurrence and progression. Methods: A systematic review of the literature was performed to synthesize current evidence on the mechanisms of tumor recurrence and progression following RFA for HCC, and to discuss corresponding preventive and therapeutic strategies. Results: Insufficient radiofrequency ablation (IRFA) is a significant driver of tumor recurrence and progression. Post-ablation relapse is not a simple process of residual cell repopulation but a multifaceted vicious cycle initiated by ablation stress. The core mechanism involves residual tumor cells surviving within a synergistic, pro-tumorigenic microenvironment characterized by thermal injury, hypoxia, inflammation, non-coding RNA dysregulation, epigenetic alterations, and immunosuppression. This hostile niche exerts intense selective pressure, activating a complex molecular cascade that promotes cell survival, immune evasion, and malignant proliferation, ultimately driving rapid progression and invasive recurrence. Conclusion: IRFA for hepatocellular carcinoma leaves behind residual tumor cells that acquire aggressive malignant phenotypes through diverse biological mechanisms, driving disease recurrence and progression. Enhancing the precision of ablation techniques and developing integrated, multi-modal treatment strategies are promising avenues to suppress post-ablation recurrence and improve long-term patient outcomes.
