A "Cartes d'Identite des Tumeurs" (CIT) project from the french Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net). 37 samples hybridized on Affymetrix HG-U133A arrays. Analysis of advanced breast cancers treated with a dose-intense epirubicin /cyclophosphamide regimen followed by mastectomy; Validation of TP53-related genes in breast and bladder cancers. We found that a complete response to chemotherapy was only observed in TP53 mutant tumours. We further show that, among TP53 mutant tumours, high basalcytokeratin and low ESR1 expression levels were associated with complete responses. These observations pave the way to molecular tailoring of chemotherapy in breast cancer.
