We examined the survivin expression pattern by immunohistochemistry in 43 fibroadenomas and 153 ductal carcinomas of the breast. The subcellular localization of survivin and the intensity of immunoreaction were assessed. We analyzed the differences of survivin expression between fibroadenomas and carcinomas. We also correlated the survivin expression pattern in carcinomas with other clinicomorphological parameters such as the age of patients, the grade and size of primary tumor as well as the lymph node metastasis. Overall, survivin was detected in 107/153 carcinomas (69.9%) and in 26/43 fibroadenomas (60.5%). Statistical analysis confirmed significant correlations between the assessed parameters in fibroadenomas and carcinomas. Grade of carcinomas was significantly related to survivin expression in both subcellular localization and the intensity of immunoreaction. Tumor grade 3 was associated with nuclear positivity and combined nuclear and cytoplasmic localization. Carcinomas larger than 20 mm showed nuclear and combined localization in 81% of cases and higher intensity of survivin immunoreaction was also notably related to larger carcinomas. Statistically significant differences were also observed between subcellular survivin localization and intensity of immunoreaction. Our result suggest that nuclear accumulation of survivin is associated with proliferative fenotype and survivin was shown to be a worse prognostic marker in breast ductal carcinoma.
