抄録

Vascular invasion of gastric carcinoma were studied in 102 cases of resected stomach cancer from view of the connective tissue's proliferation.<br>1) Blood vessel invasion were classified in three types, as follows: Extraluminal type, Embolus type and Floating type. Extraluminal type included invasion of tumor cell out of intima.<br>The common type of blood vessel invasion in well diff. adenocarcinoma were embolus and floating type, while in poorly diff. adenocarcinoma were extraluminal type.<br>2) The lymph vessel invasion were more prominent in poorly diff. adenocarcinoma.<br>3) From electron microscopic observation of connective tissue's proliferation, in medullary carcinoma, embolus and floating type were more frequently than extraluminal type.<br>Conversely, in scirrhous carcinoma. Extraluminal type was the most common.<br>These findings indicated that type of vascular invasion might be strongly affected not only by cancerous proliferation but also by connective tissue's proliferation.
