Outcomes of robotic liver resection and intraoperative radiofrequency ablation for hepatocellular carcinoma in posterior segments VII and VIII

For HCC in challenging liver segments VII and VIII, R-LR and RIO-RFA achieve comparable outcomes in <i>de novo</i> cases, whereas R-LR confers superior survival in recurrent disease. R-LR should be prioritized for small <i>de novo</i> HCCs and for recurrent disease overall; RIO-RFA may serve as an effective alternative in carefully selected low-risk recurrent patients. Tumor size, platelet count, and postoperative complications are key prognostic indicators to guide individualized treatment.
