Prognostic significance of heat-shock protein-27 in node-positive breast carcinoma: an immunohistochemical study.
Immunostaining for heat-shock protein-27 (HSP-27) was performed on formalin fixed-paraffin embedded sections of 890 node-positive breast carcinomas resected between 1980 and 1986. The follow-up ranged from 2.5 to 10.5 years. A polyclonal antibody (Hu27, dilution: 1/200) was used. A positive cytoplasmic staining was obtained in 383 cases (43%). No difference in distant metastasis-free survival (DMFS) or overall survival (OS) was noted between cases with positive or negative immunostaining. This study suggests that HSP-27 expression is not predictive of the outcome in node-positive breast cancer.
