Estudo citofotométrico da expressão dos marcadores tumorais Ki-67 e CD34 no adenocarcinoma de próstata

Abstract

The cytophotometric expression of Ki-67 had a mean labeling index of 64.04%, and the mean CD34 labeling index was 61.64%. The cytophotometric expression of the mean optical density of Ki-67 was 39.49, while for CD34 it was 53.69. There was a significant difference between Ki-67 and CD34 immunostaining with respect to optical density (P=0.025); no significant difference occurred regarding labeling index (P=0.470).
