CARCINOMA OF THE PANCREAS - Definition



Carcinoma of the pancreas is an al­most universally fatal malignancy, over 90 per cent representing an adenocarcinoma arising from ductal cells. Much rarer are islet cell tumors (not discussed here), epidermoid tumors, or adeno­carcinomas arising from acinar cells. Carcinoma of the pancreas seems to be increasing in inci­dence and is now the fourth most common ma­lignant tumor (after tumors of the lung, colon, and breast), accounting for about 5 per cent of deaths from cancer.

Etiology and Pathogenesis. The cause of car­cinoma of the pancreas is not known. Epide­miological studies have suggested the following risk factors: advancing age, smoking, diabetes mellitus, some forms of chronic pancreatitis, and certain dietary habits (increased consumption of animal fat and protein). A reported association with excessive consumption of coffee is uncon­firmed.
