Radiofrequency Ablation Covering the Entire Tumor Blood Drainage Area Improves Survival in Hepatocellular Carcinoma
Masashi Hirooka, Yohei Koizumi, Takaaki Tanaka, Kotarou Sunago, Yoshiko Nakamura, Takao Watanabe, Osamu Yoshida, Yoshio Tokumoto, Masanori Abe, Yoichi Hiasa – 15 March 2021 – Hepatocellular carcinoma has been considered to disseminate through the tumor blood drainage area. To improve curation rates, treatment should cover this area as it may contain satellite lesions. This retrospective study aimed to investigate whether radiofrequency ablation (RFA) completely covering the blood drainage area can improve the overall and disease‐free survival.
