[Cytologic findings in infiltrative carcinoma of the breast]

In the work different cytologic patterns of infiltrative breast carcinoma are systematized. Based on cytomorphological, cytometric and cytochemical studies 3 types of cancer cytographs are distinguished: low-differentiated, with a moderate differentiation of the parenchyma and high-differentiated. This systematization may enable the precise cytological conclusion to be made, but in a number of cases the histological typing of a tumor too. The cytological data on the degree of cancer dedifferentiation may be used clinically to prognosticate the immediate effect of irradiation on the tumor. The degree of breast cancer dedifferentiation, evidenced by cytological preparations, not always corresponds to the grade of tumor malignancy revealed histologically.
