Both cholelithiasis and alcohol were main etiologic factors in the more northern countries studied, whereas cholelithiasis alone predominated in the more southern ones. Mortality was high for necrotic pancreatitis; it was similar among the various etiologic groups, and there was no relationship between mortality and age.

The results show that the diagnostic value of plasma CgA in neuroendocrine tumours is relatively low; it may be of some interest only in patients with advanced disease and liver metastasis. Gastrinoma seems to be an exception, because in this tumour high CgA values are generally found even in the absence of liver metastasis.

Diabetes in patients with pancreatic cancer is frequently of recent onset and is presumably caused by the tumor. Diabetes is not a risk factor for pancreatic cancer.
