Insulin secretion is mainly regulated by blood glucose concentration. On the other hand, changes in peripheral insulin sensitivity induce compensatory adaptations in pancreatic β-cells to maintain normoglycaemia. Tumour presence causes dramatic alterations in glucose homeostasis and insulin secretion because of
