BACKGROUND AND OBJECTIVE The objective of the present study was to investigate the mutational spectrum of BRCA1 and BRCA2 in the Valencian Community, comparing this spectrum with that reported in Spain. We also analyze the association of the mutations with the family history of the selected families. PATIENTS AND METHOD We analyzed the mutations in the(More)
BACKGROUND CYP2D6 is a key enzyme in tamoxifen metabolism, transforming it into its main active metabolite, endoxifen. Poor CYP2D6 metabolizers (PM) have lower endoxifen plasma concentrations and possibly benefit less from treatment with tamoxifen. We evaluated tamoxifen dose adjustment in CYP2D6 PM patients in order to obtain plasma concentrations of(More)
PURPOSE Capecitabine is an active drug in metastatic breast cancer (BC). GEICAM/2003-10 is an adjuvant trial to investigate the integration of capecitabine into a regimen of epirubicin and docetaxel for node-positive early BC. PATIENTS AND METHODS Patients with operable node-positive BC (T1-3/N1-3) were eligible. After surgery, 1,384 patients were(More)
Biological changes that occur during metastatic progression of breast cancer are still incompletely characterized. In this study, we compared intrinsic molecular subtypes and gene expression in 123 paired primary and metastatic tissues from breast cancer patients. Intrinsic subtype was identified using a PAM50 classifier and χ2 tests determined the(More)
