Effects of smoking cessation on insulin and cardiovascular risk factors--a controlled study of 4 months' duration

MIB-1 Ki-67 and PCNA scores in infiltrating ductal NOS breast carcinomas were compared. The correlation between MIB-1, Ki-67 and PCNA indices and several clinicopathological factors that have prognostic significance in breast cancer was also assessed. The mean Ki-67, MIB-1 and PCNA indices were 13.4%, 19.4%, 27.6%, respectively. Significant positive linear correlation was found only between Ki-67 and MIB-1 indices. PCNA score did not correlate with Ki-67 and MIB-1 indices. The significant correlation between Ki-67 and MIB-1 scores and histological grade was found. There was no correlation between Ki-67 and MIB-1 indices and axillary lymph node status or tumor diameter. The results suggest that MIB-1 antibody is an excellent tool for assessment of proliferative rate of breast cancer cells in paraffin sections.
