Abstract Purpose: The purpose of this study was to determine the prognostic role of hormone receptor (HR) on inflammatory breast cancer (IBC) to elucidate its aggressive biological behavior.Methods: We evaluated the expression of estrogen receptor (ER) and progesterone receptor (PR) by immunohistochemical staining and determined the predictive and prognostic role of HR expression on 189 patients with HR+/HER2– IBC and 677 patients with HR+/HER2– stage III non-IBC. Furthermore, we performed gene expression (GE) analyses for 137 patients with HR+/HER2– IBC and 252 patients with corresponding non-IBC to detect genes that are specifically overexpressed in IBC.Results: The expression of ER% was significantly associated with longer distant disease-free survival and overall survival. However, there was no significant relationship between ER% and NAC outcome. In the GE study, 84 genes were identified as significantly distinguishing HR+ IBC from non-IBC. Among the top 15 canonical pathways expressed in IBC, the ERK/MAPK, PDGF, insulin receptor, and IL-7 signaling pathways were associated with the ER signaling pathway. Upregulation of the MYC gene was observed in three of these four pathways. Furthermore, HR+/HER2– IBC had significantly higher MYC amplification, and the genetic alteration was associated with poor survival outcome.Conclusions: Increased HR positivity was significantly associated with improved survival in both HR+/HER2– IBC and HR+/HER2– stage III non-IBC patients. HR+/HER2– IBC had several activated pathways with MYC upregulation, and the genetic alteration was associated with poor survival outcome. The results indicate that MYC may be a key gene for understanding the biology of HR+/HER2– IBC.

We have carried out an investigation into the processing of the enkephalin-like immunoreactivity reported in breast tissue using two human breast tumour cell lines and a mouse tumour cell line. A 46 kDa form of proenkephalin (PE) has been observed in the cell lysates of two human breast tumour cell lines (MCF-7, ZR-75-1) and the mouse androgen-responsive Shionogi breast carcinoma cell line (SC115). PE processing in the cell lysates of these cells was assessed by a specific met-enkephalin RIA. The basal levels of processed PE in the MCF-7, ZR-75-1 and SC115 cell lysates were 30, 30 and 76% respectively. The processing enzymes PC1 and PC2, which have been implicated in the differential processing of PE, were detected by immunoblot analysis in these cells. PC1 was found within the cell extracts of all three cell lines. PC2 was only observed in the SC115 cell line, which may account for the higher percentage of processed PE measured. The cDNA of PC2 has been transfected into ZR-75-1 cells and this was accompanied by an increase in the level of processed PE from 30 to 76%. These breast tumour cell lines may provide a useful insight into the function of enkephalin-containing peptides in breast cancer.
