pubmed:abstractText |
Over the past 5 years, several clinical studies on a total of approximately 2500 patients have shown that the immunocytochemical detection of occult metastatic tumor cells in bone marrow (BM) at primary surgery provides important prognostic information in breast cancer (e.g., Ref 13 ). Here, we evaluated whether these cells can survive first-line chemotherapy and express epithelial cell adhesion molecule (Ep-CAM), recently suggested as promising target for immunotherapeutic interventions in breast cancer. Experimental Design: A total of 62 patients with node-negative and -positive breast cancer but without distant metastases (Tumor-Node-Metastasis stage M(0)) was treated with two or more courses of various forms of adjuvant chemotherapy (e.g., cyclophosphamide-methotrexate-5-fluorouracil, anthracyclines). After chemotherapy, BM was aspirated from the upper iliac crest and analyzed for the presence of tumor cells. A first cohort of 34 BM aspirates was enriched for tumor cells by Ficoll density gradient centrifugation, and 2-4 x 10(6) mononuclear cells were analyzed per patient. The tumor cells were detected by anticytokeratin monoclonal antibody (Mab) A45-B/B3 and double labeled with Mab 3B10 against an Ep-CAM-epitope. The subsequent 27 BM aspirates were specifically enriched for Ep-CAM(+) cells using magnetic beads coupled to Mab 3B10, and tumor cells were identified by Fab fragments of Mab A45-B/B3 directly conjugated with alkaline phosphatase.
