ON CORRELATION AMONG BLOOD FLOW, HISTOLOGICAL PATTERN AND CAPILLARY QUANTITY IN THE BREAST CARCINOMA

Abstract

The investigation on correlation among blood flow, histological pattern and capillary quantity was carried out in the breast carcinoma.
The blood flow of tumor was calculated by a half time (Tl/2) examined by ¹³³Xe clearance curve and following formula.
B. F. (ml/100 g/min) =100×λ×log_e2/T1/2
The angiography was performed on the resected breast tissue. The resected breast tissue was made into slices of 2-4 mm thick after fixation and microangiography was taken.
As a results, 1) significant difference was observed in blood flow between scirrhous carcinoma and others but not observed between medullary tubular carcinoma and papillary tubular carcinoma.2) Capillary quantity was poorer in scirrhous carcinoma than in medullary tubular carcinoma as well as in papillary tubular carcinoma.
Blood flow and capillary quantity were different according to histological pattern in the breast carcinoma but seemed to be related each other.
