Abstract Introduction We report a patient with a rapidly progressing recurrence of hepatocellular carcinoma (HCC) with a portal vein tumor thrombus after radiofrequency ablation of the original lesion, then treated with transcatheter arterial infusion. Radical hepatic resection demonstrated a complete pathological response. Presentation of case A 60-year old male with alcoholic cirrhosis and gastric varices was diagnosed with HCC measuring 12 mm in segment 8. He underwent laparoscopic radiofrequency ablation, but recurred three months later. The lesion progressed rapidly and the right portal vein was occluded. He then underwent transcatheter arterial infusion with miriplatin and iodized oil, which was effective in reducing the size of the main lesion and portal vein tumor thrombus. Right anterior sectionectomy was then performed. Pathologically, there were no viable HCC cells in either the main lesion or the portal vein thrombus. He is alive two years and nine months after surgery without recurrence. Discussion A rapidly progressing HCC recurrence with portal vein tumor thrombus is usually associated with a poor prognosis. No effective treatments have been reported in this situation except hepatic resection. In this patient the tumor was effectively reduced after three courses of transarterial miriplatin and subsequent radical hepatic resection. This is the first report to achieve a complete pathological response for such an aggressive recurrence after initial radiofrequency ablation. Conclusion This strategy may result in long-term survival of patients with rapidly progressing recurrent HCC with portal vein thrombus, and further study is warranted.
