Abstract
We studied thrombophilic genetic factors (TGFs) MTHFR C677TT, PAI1 4G-4G, V Leiden Q506, prothrombin G20210A as risk factors in 94 patients with HCC with and without portal vein thrombosis (PVT), compared with 214 patients with liver cirrhosis (LC) with and without PVT and 94 healthy controls (HC). The OR (95% CI) for MTHFR C677TT with HCC was 3.85 (1.55-7.39) vs. HC. The OR for PAI1 4G-4G in HCC, was 2.87 (1.27-6.55) vs. HC. Also prothrombin G20210A was significantly more frequent among HCC, mainly in patients with PVT, while V Leiden factor was equally distributed among HCC and HC. Differences were more significant in patients with associated PVT. These findings suggest that frequently TGFs are needed for patients to be at risk of HCC and PVT. We conclude that in all patients with chronic liver disease TGF screening should be performed to individuate patients at risk of HCC and PVT.
