[Chemotherapeutic pathomorphosis of breast cancer].

Features of pathomorphism of mammary carcinoma were studied in 177 women after a course of drug therapy. Qualitative and quantitative morphologic changes in the tumor were poorly manifest: they were detected in only 54 percent of patients and only in 9 percent the effect was manifest (third-fourth stage of involvement). Characteristic findings here were augmentation of cellular dystrophy, necrotic changes, enhanced nuclear polymorphism; significant injury to tumor parenchyma was paralleled by development of xanthomatosis foci and lymphoid histiocytic infiltration.
