dc.description.abstractPURPOSE: The utility of three different epithelial mRNA markers to detect clinically significant, disseminated tumour cells in bone marrow (BM) was explored. METHODS: Mammaglobin A (hMAM), trefoil factor 1 (TFF-1) and prostate derived Ets factor (PDEF) mRNA were quantitated by real-time RT-PCR in BM samples from 192 breast cancer patients undergoing surgery (control group: 26 healthy women). RESULTS: During a median follow-up of 72 months, four of the five hMAM BM-positive and three of the seven TFF-1 BM-positive patients experienced a systemic relapse. Kaplan-Meier survival analyses demonstrated significantly shorter recurrence-free-, breast-cancer-specific- and overall survival for both hMAM and TFF-1 BM-positive patients. In contrast, PDEF mRNA quantitation did not reveal any significant differences in the survival analyses. Multivariate Cox regression demonstrated hMAM mRNA BM expression to be an independent predictor of both overall- (hazard ratio = 5.896), breast-cancer-specific- (hazard ratio = 10.208) and systemic-recurrence-free survival (hazard ratio = 14.304). TFF-1 status was related to hMAM status (P < 0.001). CONCLUSION: Breast cancer patients with pre-operative elevated BM levels of hMAM and/or TFF-1 mRNA seem to constitute a small group of patients with a very poor prognosis.en
