Early (stage A) prostatic cancer. V. Stereotopography.

In 67 prostates, collected at autopsy, besides length, the following measures were taken or calculated (Leitz, ASM): width, thickness (antero-posterior axis) and correlative half-diameters, mean area and ratio area/perimeter. When prostatic microcarcinoma was present, the angle to the antero-posterior axis and the mean percent distance from the urethral barycentre were calculated; over 74% of all cancer foci were in the lateral sextants between iso-distances 50-90.
