[Spread of pancreatic cancer into the adjacent organs].

Observations over 250 patients with cancer of the pancreas allowed the author to present the data on metastasization and proliferation of cancer in the adjacent organs. Proliferation on the pancreatic head cancer was observed in 55.4% of patients and most frequently in upper mesenterial vessels, the portal vein, hepatic and splenic artery. In cancer located in distal portions of the gland proliferation was noted in 60% of observations, and mainly in the hepatoduodenal ligament and mesentery of the small and large intestine. Metastasization was more frequently noted both in tumor located in distal portions of the gland and in generalization of the process. Thus, cancer of distal portions of the pancreas shows a more aggressive course than cancer of the pancreatic head.
