Quantify prostate cancer by automated histomorphometry

Abstract

A new method is presented to quantify malignant changes in histological sections of prostate tissue immunohistochemically stained for prostate-specific antigen (PSA) by means of image processing. The morphological analysis of the prostate tissue uses the solidity of PSA-positive prostate tissue segments to compute a quantitative measure that turns out highly correlated with scores obtained from routine diagnosis (Gleason, Dhom).
