A comparison between three-dimensional conformal radiotherapy combined with interventional treatment and interventional treatment alone for hepatocellular carcinoma with portal vein tumour thrombosis.

Introduction: We investigated the therapeutic effects of three-dimensional conformal radiotherapy combined with transcatheter arterial chemoembolisation (TACE) for hepatocellular carcinoma (HCC) with portal vein tumour thrombosis (PVTT).

Methods: Sixty-three HCC patients with PVTT were divided into two groups. Group A (30 patients) was treated with three-dimensional conformal radiotherapy followed by 2-3 series of TACE, while group B (33 patients) was only treated with TACE.
