Abstract

Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is associated with a dismal prognosis. Atezolizumab plus bevacizumab (atezo-bev) is the recommended palliative treatment, and approximately 10% of the patients may experience a complete response (CR), according to the mRECIST criteria. The treatment duration is until disease progression or unacceptable side effects occur. Long-term continuation can cause potential toxicities and a substantial financial burden, making early treatment discontinuation a viable option. This report describes durable CR after discontinuing atezo-bev treatment in three patients with HCC and PVTT.
