Tissue and serum adiponectin levels in patients with gastric cancer: are there any correlations between adiponectin levels and histopathological variables?

Background/aims: Adiponectin is secreted from adipose tissue and is characterized by hyperinsulinemia, which is related with obesity. Adiponectin levels are significantly lower in gastric cancer patients than in healthy controls. The aim of this study was to investigate the relationship between adiponectin levels in serum, tumor tissue and normal tissue with some other insulin resistance parameters.
