Successful treatment with laparoscopic surgery and sequential multikinase inhibitor therapy for hepatocellular carcinoma: A case report

Abstract

BACKGROUNDHepatocellular carcinoma (HCC) with massive portal vein tumor thrombosis (PVTT) and distant metastasis is considered unresectable. However, due to recent developments in systemic chemotherapy, successful cases of conversion therapy for unresectable diseases have been reported. Herein, we report a successful multidisciplinary approach for treatment of multi-visceral recurrence with sequential multikinase inhibitor and laparoscopic surgery.CASE SUMMARYA 63-year-old woman with chronic hepatitis B virus infection was diagnosed with HCC. Subsequently, she underwent two rounds of laparoscopic partial hepatectomy, laparoscopic left adrenalectomy, and transcatheter arterial chemoembolization plus sorafenib for recurrence. Four years after initial hepatectomy, she presented with a 43-mm mass in the spleen and tumor thrombus involving the main portal vein trunk with ascites. Her liver function was Child-Pugh B (8), and protein induced by vitamin K absence or antagonist II (PIVKA II) levels were elevated up to 46.291 mAU/mL. Since initial treatment with regorafenib for three months was unsuccessful, the patient was administered lenvatinib. Ten months post-treatment, there was no contrast enhancement of PVTT or splenic metastasis. Chemotherapy was discontinued due to severe diarrhea. Afterward, splenic metastasis became viable, and PIVKA II increased. Therefore, hand-assisted laparoscopic splenectomy was performed. She experienced no clinical recurrence 14 mo after resection.CONCLUSIONConversion surgery after successful multikinase inhibitor treatment might be considered an effective treatment option for advanced HCC.
