Conversional Effects of TILA-TACE Combined with 3D-CRT on An Unresectable HCC with Type IIIb Tumor Thrombus in the Right Hepatic Vein
摘要
Hepatocellular carcinoma (HCC) with tumor thrombus involving major vessels often indicates an unresectable advanced stage and poor prognosis. Targeting-intratumoral-lactic-acidosis transarterial chemoembolization (TILA-TACE) combined with three-dimensional conformal radiation therapy (3D-CRT) may downstage HCC and improve resectability. We report a 60-year-old man presenting with a one-month history of constipation. Magnetic resonance imaging revealed a hepatic mass with tumor thrombus of the right hepatic vein extended to the inferior vena cava proximal to the right atrium. A clinical diagnosis of stage IIIa HCC was established. The patient underwent TILA-TACE, 3D-CRT, and a second TILA-TACE in turn, with a two-week interval respectively. As a result, the tumor thrombus reduced within a resectable range, subsequently, the right hemihepatectomy was successfully performed. After surgery, the patient recovered uneventfully. In conclusion, TILA-TACE combined with 3D-CRT could take effects on the unresectable HCC mentioned above, likely converting an unresectable or a potential resectable HCC into a resectable one.
