Abstract

Although several molecular markers have been proposed as prognostic of disease progression in Hepatocellular carcinoma (HCC), predictive markers of response to treatment are still unsatisfactory. Here, we propose a genetic polymorphism as a potential predictive factor of poor prognosis in HCC patients treated with transcatheter arterial chemoembolization (TACE). In particular, we show that the guanosine insertion/deletion polymorphism in the promoter region of SERPINE1 gene at the -675 bp position, named 4G/4G, predicts poor prognosis in a cohort of 75 patients with HCC undergoing TACE. By a combination of ELISA and SERPINE1 promoter study, we found that the presence of elevated plasma levels of plasminogen activator inhibitor-1 (PAI-1) in patients with 4G/4G genotype is significantly associated with reduced overall survival compared to patients with 5G/5G or 4G/5G genotype in HCC patients after TACE. Our analysis provided evidence that variation in SERPINE1 gene plays a role in defining the outcome in patients treated with TACE. In addition to a poor disease outcome, the 4G/4G variant represents an unfavorable predictive factor for response to chemotherapy as well.
