Hsp-27 Expression in Invasive Ductal Breast Carcinoma
open access
Abstract
The aim of this study was to determine the intensity of Hsp-27 protein expression in fibrocystic breast changes (FC) and invasive ductal breast carcinoma (IDC) and to examine its impact on patients’ clinico-pathological characteristics and overall survival. Immunohistochemical reactions were conducted on archival samples of 20 cases of FC and 101 cases of IDC treated in the years 1999-2002. Nuclear-cytoplasmic Hsp-27 expression was observed in 92 (92.1%) of the examined cases of IDC and all the cases of FC. Significantly higher Hsp-27 expression was observed in G2 (p<0.01) and G3 cases (p<0.0001) as compared to FC. HER-2 positive cases had higher Hsp-27 expression (p=0.0153), than HER-2 negative cases. Our research showed that Hsp-27 could have a impact on tumour malignancy. Moreover, the positive correlation between expression of Hsp-27 and HER-2 positive cases was demonstrated.
