Analysis of Expression Patterns of Breast Cancer–Specific Markers (Mammaglobin and Gross Cystic Disease Fluid Protein 15) in Lung and Pleural Tumors

Abstract

The sensitivity of mammaglobin is equal or superior to that of GCDFP-15 for investigation of breast carcinoma. Immunopositivity for mammaglobin is more diffuse than that for GCDFP-15. In terms of practical diagnosis, mammaglobin immunohistochemistry can serve as a differential marker of breast carcinoma and should be added to the immunohistochemical panel.
