Thrombosis and pancreatic carcinoma revisited.

A case of recurrent pulmonary embolism from thrombophlebitis associated with pancreatic carcinoma is reported. There is an increased incidence of thrombophlebitis with all tumors, but carcinoma of the pancreas is statistically more frequently responsible. The higher incidence of thrombophlebitis with tumors of the body and tail of the pancreas is probably due to the low trypsin levels associated with these tumors. Trypsin levels are directly related to plasma antithrombin levels and mucinous adenocarcinomas are more commonly associated with thrombus formation.
