However, the results of multidisciplinary treatment including hepatic resection are still unclear. The present study evaluated the outcomes of MTA treatment for advanced, unresectable hepatocellular carcinoma (HCC), with the goal of achieving liver resection, in our department. Patients and Methods: Nine patients in whom Lenvatinib had been administered to achieve conversion surgery for unresectable HCC were included in this study. The patient characteristics were as following: median tumor size of 10 cm, vascular invasion in 5 cases, multiple tumors in 2 cases, median treatment duration of 8 weeks, dose reduction due to side effects in 4 patients, and discontinuation of treatment in 1 patient due to tumor growth. Results: The efficacy by modified Response Evaluation Criteria in Solid Tumors (mRECIST) was partial response in 3, sustained disease in 5 and progressive disease in 1, while the liver resection rate was 88%. Four patients (50%) had recurrence after resection, and the median recurrence-free survival was 12.7 months; however, treatment for recurrence was successful and all patients are alive. Conclusion: Lenvatinib may improve the prognosis of HCC with vascular invasion and multiple lesions by achieving radical resection at the appropriate time for patients with tumor shrinkage. ER -
