[A Case of Hepatocellular Carcinoma Evaluated as Complete Response by Combined Lenvatinib and Radiofrequency Ablation Therapy].

We report a case of hepatocellular carcinoma evaluated as complete response by combined lenvatinib and radiofrequency ablation therapy. A 74-year-old man visited our hospital because medical examination abdominal ultrasonography revealed a liver tumor. Abdominal MRI and CT showed a 3.3 cm tumor on the right hepatic vein in segment 7 of the liver, and hepatocellular carcinoma was diagnosed. Lenvatinib was administrated for 6 months, and laparoscopy-assisted radiofrequency ablation was performed as additional treatment. After 1 month, dynamic CT showed the disappearance of intratumoral arterial lesion enhancement and low density lesion area. The therapeutic effect was evaluated as a complete response.
