Abstract

A combined therapy of atezolizumab and bevacizumab (atezo/bev) is used as the first-line treatment for unresectable hepatocellular carcinoma (HCC). In this study, we report the case of curative hepatic resection in a 77-year-old man who initially had unresectable advanced-stage HCC with lung metastases. This rare hepatectomy conversion was owing to the administration of atezo/bev. Notwithstanding the side effects of immune-related adverse event hepatitis and intratumoral hemorrhage developed during atezo/bev treatment; after seven treatment cycles, the patient’s tumor markers normalized, the tumor shrank markedly, and the metastasis disappeared. Subsequently, conversion therapy with hepatic resection was performed, and pathology confirmed complete tumor necrosis. No cancer recurrence was observed at the 8-month postoperative follow-up, and the patient remained drug free.
