A new risk prediction model for patients with HCC treated with TARE (Y-scoring system) was established from the training cohort using five independent baseline variables [serum albumin < 3.5 g/dL, hazard ratio = 5.446; alpha-fetoprotein > 200 ng/mL (hazard ratio = 5.071); tumor number ≥ 3 (hazard ratio = 2.933); portal vein thrombosis (hazard ratio = 4.915); and hepatic vein invasion (hazard ratio = 8.500)] and two on-treatment variables [no des-gamma-carboxy prothrombin response (hazard ratio = 15.346) and progressive disease at three months (hazard ratio = 4.154)] for mortality (all P < 0.05).
The disseminated intravascular coagulation (DIC) score, which is based on readily available and relatively inexpensive coagulation parameters, including platelet count, fibrin-related markers, prothrombin time and fibrinogen, has not been reported regarding PVT development in cirrhotic patients to date.
In this case-control study, we investigated the frequency of Janus kinase 2 (JAK2) (JAK2 V617F), Factor V Leiden (FVL G1691A), and Prothrombin (G20210A) mutations in cirrhotic patients with PVT (LCi+/PVT+ group, n = 21) in comparison with two control collectives (cirrhotic patients without PVT, LCi+/PVT- group, n = 43; PVT patients without liver cirrhosis, LCi-/PVT+ group, n = 29).
The prevalence of the FVL and prothrombinG20210A mutations were compared between patients with Budd-Chiari syndrome or PVT without cirrhosis and healthy individuals (controls) and between patients with cirrhosis, with and without PVT.
The following variables were related to PVT: prothrombin levels, platelet count, Child-Pugh classification, previous abdominal surgery, number of decompensation events, size of varices, red markers on varices, and sclerotherapy.
Most patients were in class Child-Pugh B and C. Among thrombophilic risk factors studied only the mutation 20210 of the prothrombin gene resulted independently associated to PVT.
The inherited deficiencies of protein C, protein S, antithrombin III, factor V Leiden mutation, prothrombin gene polymorphism, and antiphospholipids were studied in 53 Budd-Chiari syndrome (BCS) and 33 portal vein thrombosis (PVT) cases and compared with 223 age- and sex-matched controls.
The factor V (FV) G1691A mutation, the prothrombin (PT) G20210A variant, the methylenetetrahydrofolate reductase (MTHFR) T677T genotype, together with fasting homocysteine (HCY) concentration, lipoprotein (Lp)(a), anti-thrombin (AT), protein C (PC), protein S (PS) and anti-cardiolipin antibodies were investigated in 65 consecutively recruited infants (neonate to < 12 months) with renal venous thrombosis (RVT; n = 31), portal vein thrombosis (PVT; n = 24) or hepatic vein thrombosis (HVT n = 10), and 100 age- and sex-matched healthy controls.
