Abstract

Background: Macroscopic portal vein thrombosis (PVT) is a common and dire prognostic feature of patients with hepatocellular carcinoma (HCC) and often precludes many treatments as a result. Little is known about its causes or mechanisms or clinical associations. Aims: To examine patients with PVT in order to possibly identify prognostically different subsets. Methods: A large cohort of non-curable patients with advanced and biopsy-proven HCC in which survival was documented, were retrospectively examined. Results: We analyzed a large HCC cohort containing 366 (63.3 %) PVT-positive patients and found that PVT is associated with patients having larger tumors and higher levels of alpha-fetoprotein (AFP) and des-gamma carboxyprothrombin (DCP). We identified in patients with normal bilirubin levels (≤2.0 mg/dl) two PVT-positive patients, having higher and lower AFP levels, respectively. They differed in the significantly better prognosis of the low AFP patients, which may be useful for patient management decisions. Conclusions: Patients with PVT are heterogeneous with respect to AFP levels. AFP-negative patients have a significantly better survival than those who have elevated AFP.
