Abstract:
:Determination of breast cancer estrogen receptor (ER) status as a predictor of tumor response to adjuvant endocrine therapy remains a mainstay of breast cancer management. Recent second generation anti-ER antibodies and new epitope retrieval methods have produced paraffin-based immunohistochemical results that correlate closely with the dextran-coated charcoal (DCC) assay and appear to represent a superior method of ER assay. The authors determined the ER status of 103 invasive breast cancers by paraffin-based, automated immunohistochemistry on the Ventana ES using a new monoclonal antibody, CC4-5, and compared the results to those of parallel DCC biochemical analysis and manual immunohistochemical analysis using anti-ER monoclonal antibody ER1D5. The specificity of the CC4-5 antibody for ER protein was confirmed by Western blot analysis. Sixty of 103 cases were positive for ER by CC4-5 automated immunohistochemistry. With a ligand binding assay threshold value of 20 fmol/mg protein, there were 50 positive cases by biochemical assay. The biochemical results corresponded to an 88% rate of agreement with automated CC4-5 staining. Analysis of discordant cases revealed that the majority of CC4-5 immunopositive only cases (8 of 11) were strongly positive, stroma rich tumors, suggesting that corresponding biochemical measurements were diluted by non representative stromal tissue. There was only one immunonegative, biochemically positive case (27 fmol/mg protein). Semiquantitation of CC4-5 staining using percent positive tumor cells or weighted average staining intensity (HSCORE) showed moderate to good correlation with quantitative DCC results (r = 0.64 and 0.62, P < .0001). ER1D5 was not suitable for use on the Ventana ES, most likely due to temperature constraints of the instrument. By manual ER1D5 staining, 40 of 79 examined cases were positive corresponding to a 99% rate of agreement with automated CC4-5 staining. Semiquantitation of ER1D5 staining by percent positive tumor cells and weighted average staining intensity (HSCORE) showed excellent correlation with semiquantitation of automated CC4-5 results (r = 0.90 and 0.88, P < .0001). Automated immunohistochemistry using the Ventana ES and monoclonal antibody CC4-5 is a reliable method for determining breast cancer ER status. As with other immunohistochemical methods, direct correlation with morphology precludes errors due to tissue sampling, allowing for accurate analysis of stroma-rich or partially necrotic tumors and small neoplasms that otherwise would yield insufficient tumor tissue for biochemical analysis.
