Popis: Several biochemical pathways can lead to cancer cachexia, one of which involves the elevation of the cytokines, such as tumor necrosis factor alpha (TNF-alpha) and interferon gamma (INF-gamma). It was suggested that TNF-alpha and INF-gamma genes polymorphisms may influence these cytokines serum levels, but published data are still controversial. The aim of our study was to assess the clinical significance of -308G/A TNF-alpha and +874A/T INF-gamma genes polymorphisms as well as TNF-alpha and INF-gamma serum levels in pancreatic adenocarcinoma (PA) and chronic pancreatitis (CP) as regards to healthy volunteers. We studied 41 patients with pancreatic adenocarcinoma, 56 with chronic pancreatitis and 50 healthy volunteers. Peripheral venous blood samples were obtained from all patients for TNF-alpha and INF-gamma serum concentrations measurement. After DNA isolation TNF-alpha and INF-gamma genes polymorphisms have been studied using restriction fragment length polymorphism (RFLP) analysis. Plasma levels of TNF-alpha were significantly higher in PA patients (32.7 pg/ml) compared with CP patients (3.2 pg/ ml) and control group (
