High VEGF serum values are associated with locoregional spread of gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are highly vascularized neoplasms, capable of synthethisizing VEGF-A, a key mediator of angiogenesis. In pancreatic neuroendocrine tumors (pNETs) VEGF expression is higher in benign and low-grade tumors and associated with good prognosis (neuroendocrine paradox) while the VEGF role in gastrointestinal NETs (GI-NETs) is still unclear. In this study, we examined the VEGF-1154A/G polymorphism in 145 GEP-NET patients and 150 controls.

Interleukin 1β gene single-nucleotide polymorphisms and susceptibility to pancreatic neuroendocrine tumors.

Pancreatic neuroendocrine tumors (pNETs) are rare neoplasms with not fully understood etiology. Interleukin 1β (IL1β) plays an important role in pancreatic pathology, especially carcinogenesis, but its role in pNET development remains unknown. The aim of this study was to analyze the association between IL1β polymorphisms and susceptibility to pNETs.

IL-2 -330 T/G SNP and serum values-potential new tumor markers in neuroendocrine tumors of the gastrointestinal tract and pancreas (GEP-NETs).

Cytokines participate in tumorigenesis of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Single nucleotide polymorphisms (SNPs) in cytokine genes influence expression of proteins and are evaluated in cancer susceptibility. The aim of this study was to evaluate IL-2 -330 T/G SNP and susceptibility to GEP-NETs, and analyze the correlation between G-allele and IL-2 serum values in GEP-NET patients.

IL-6-174 C/G polymorphism in the gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

IL-6 is a pleiotropic cytokine with still controversial role in tumorigenesis of different cancer types. Its promoter SNP-174 C/G is associated with increased IL-6 transcription and in some tumor types with elevated IL-6 serum levels. The role of IL-6 polymorphisms and IL-6 serum values and their correlation in the gastroenteropancreatic neuroendocrine tumors is lacking.

Plasma interleukin-8 as a potential predictor of mortality in adult patients with severe traumatic brain injury.

Because of complex pathophysiology and severe consequences, traumatic brain injuries (TBI) are an important medical problem. Pathophysiology of TBI includes local and systemic stress response, in which interleukin-8 (IL-8) is considered as a key mediator of neuroinflammation. However, prognostic relevance of IL-8 measurement in adult patients with severe TBI is not certain.

Clinical and neurohumoral response to posture, physical exercise, and ascites treatment in Child-Pugh C liver cirrhosis: randomized prospective trial.

Aim: To assess clinical and neurohumoral response to posture, physical exercise, and ascites treatment in patients with Child-Pugh C liver cirrhosis and tense ascites.

Method: Fifty patients with Child-Pugh C liver cirrhosis and tense ascites were randomly allocated into 5 groups. Thirty patients were treated with paracentesis of 6 L of acites paralleled by plasma volume expansion with 200 mL of 20% low sodium albumin (10 patients), 600 mL fresh frozen plasma (10 patients), or 900 mL solution of synthetic gelatine (10 patients), ie, doses with comparable oncotic power, and bed rest for 24 h before and after the procedure.
