Heterogeneity of apoptotic and mitotic indices in breast cancer

Heterogeneity of apoptotic and mitotic indices in 7 untreated, resected breast cancers that ranged from 1.5 to 5.0 cm in pathological diameter. CV is the coefficient of variation (SD/mean). The average (mean) CVs were 0.25 for apoptotic index and 0.46 for mitotic index.
