Radiofrequency Ablation Plus Systematic Neoadjuvant Therapy for Recurrent Hepatocellular Carcinoma (RANT Study)

1. To compare systemic neoadjuvant therapy (combination of immune checkpoint inhibitors and anti-angiogenic drugs (short for "targeted-immune therapy") combined with radiofrequency ablation (RFA) and RFA alone in the treatment of recurrent hepatocellular carcinoma(HCC) in 1-year recurrence-free survival (RFS) and overall survival (OS) 2. To evaluate the clinical value of systemic neoadjuvant therapy (i.e. immune checkpoint inhibitors and targeted therapy) combined with RFA in the treatment of recurrent HCC, as well as the safety and efficacy of this strategy.
