Metformin And Insulin To Pancreatic Cancer Related Diabetes (Type 3c)

Study Overview

Metformin and Insulin to Pancreatic Cancer Related Diabetes (Type 3c)

About 80% of patients with pancreatic adenocarcinoma have aberrant fasting blood glucose at the time of diagnosis. The consistent association between pancreatic cancer and diabetes mellitus has long been recognized and even been termed as Ȭhicken and egg". Many reports have found that pancreatic cancer can result in diabetes, which is called type 3c diabetes. New-onset diabetes is commonly observed in pancreatic cancer patients and has been considered as a potential screening sign. Moreover, diabetes has been found as a predictor of poor outcome in pancreatic cancer. Pancreatic cancer cells have a strong dependence on glucose and they are well-known for their sweet teeth. High glucose is associated with impaired immunologic reaction, intolerability to chemotherapy, radiotherapy and other major treatments, an increased risk of pancreatic surgery. Given the linkage between pancreatic cancer and diabetes or high blood glucose, a clinical trial is needed to validate the effect of metformin and insulin on regulating blood glucose in type 3c diabetes.
