The proliferative activity of 92 breast carcinomas was studied. Statistically significant correlations between the level of proliferative activity and degree of differentiation of tumor cells and nuclear grade were found. Statistically reliable differences in proliferative activity were revealed in the groups of patients under and over 50 years. These facts show that proliferative activity can be used as an individual factor for predicting the aggressiveness of the neoplastic process in patients with breast cancer.
