Germline mutations in either the BRCA1 or BRCA2 gene account for approximately from five to ten percent of breast cancers in population.
Breast cancers caused by mutations of BRCA1 a BRCA2 genes have usually different histopatologic characteristics and also different
biological behaviour. Individualization of therapy based on the knowledge of the molecular prognostic and predictive markers is goal of
modern oncologic treatment, and BRCA1 and BRCA2 expression might be one of them. BRCA1 or BRCA2 deficiency is not only a possible
prognostic factor and predictor of response to systemic standard chemotherapy, but might also be a predictor for type of response to
a new targeted therapy.
