Expanding the therapeutic armamentarium for advanced hepatocellular carcinoma: successful transarterial chemoembolization of peritoneal extrahepatic metastasis.

Abstract

Hepatocellular carcinoma (HCC) is predominantly known for its intrahepatic manifestations, yet extrahepatic dissemination, particularly intraperitoneal, remains rare. Herein, we present the very first case of successful transarterial chemoembolization (TACE) for an extrahepatic peritoneal HCC nodule. This intervention underscores the potential efficacy of TACE as a viable alternative to surgery in cases where arterial vessels supplying the lesion do not nourish vital parenchymal organs.
