Abstract
It is common belief that carcinoma of the pancreas has an inherent and unique ability to induce a hypercoagulable diathesis that leads to clinically significant thrombosis. We evaluated 130 consecutive patients with adenocarcinoma of the pancreas to document the incidence and the predisposing factors related to the postulated increased association of thromboembolic disorder (TED) and pancreatic carcinoma. Only nine such patients (6.9%) demonstrated TED complications of the classical Trousseau syndrome. In these instances, the location of the tumor and its mucin-producing potential were significant predisposing factors. In our series, TED was usually associated with tumors of the body and tail, which had a greater likelihood to be mucinogenic as compared with those localized to the head of the pancreas. Routine tests for hemostasis were not helpful in predicting the development of TED except, perhaps, for decreased platelet counts. Therefore, we believe that the relationship between cancer of the pancreas and TED should be de-emphasized since it is neither unique nor especially common to pancreatic carcinoma and since it may be frequently encountered in other varieties of visceral malignancies of the cancer patient population.
