Question special

Pancreatic adenocarcinoma is one of the causes of Type 3c Diabetes Mellitus. In some patients, hyperglycaemia or the diagnosis of diabetes mellitus may be the first manifestation of their pancreatic cancer.

We have had several consults over the past few weeks for management of hyperglycaemia for patients who have a new diagnosis of pancreatic cancer (often late stage), and have been diagnosed with "Type 2 Diabetes Mellitus" within the last few years. However, they do not fit the usual phenotype for Type 2 Diabetes.

I would be interested in others' experience with patients who have Type 3c pancreatogenic diabetes mellitus secondary to pancreatic cancer. Given pancreatic cancer is usually diagnosed at a late stage, is there any role for screening elderly patients who present with new diagnosis of diabetes mellitus who do not fit the usual phenotype for Type 2?
