Abstract: The antiapoptotic protein survivin is widely expressed in most human cancers, including carcinomas of the breast. It is rarely detected in corresponding normal adult tissues. Therefore, survivin comes into the limelight as a promising diagnostic biomarker and prognostic parameter. Immunohistochemically, we examined the expression of this protein in 126 cases of ductal breast carcinoma to determine the association with clinicomorphological parameters such as age of patients, grade, stage and size of the primary tumor, lymph node metastasis, vascular invasion as well as estrogen and progesterone status. In each section, the subcellular location of survivin antigen, the intensity of staining and the percentage of labeled cells were assessed. Overall, survivin was expressed in 111 cases (88.1%). The statistical analysis revealed a significant correlation between the nuclear location of survivin and tumor grade 3. Furthermore, a significant relation was also found between vascular invasion and nuclear and combined nuclear and cytoplasmic survivin expression, together with a higher intensity of immunoreaction. However, no significant correlations were shown with other clinicomorphological parameters, such as stage and size of the tumor, lymph node metastasis, estrogen and progesterone receptors and age. Our findings revealed that survivin was frequently overexpressed in carcinoma cells, where it was present in different subcellular compartments. The nuclear positivity of survivin or combined nuclear and cytoplasmic expression was shown to be a poor prognostic parameter in ductal breast carcinoma.
