摘要: Cancer intervention strategies have been increasingly focused on developing therapies that are personalized and tailored to each individual's unique genetic profile. Evolving understanding of the metabolism pharmacogenomics tamoxifen, an early example targeted therapy for women with hormone receptor-positive breast cancer, has created decision-making challenges healthcare providers their patients. This article reviews pharmacology genetics physiology CYP2D6 enzyme system important effects tamoxifen metabolism, subset data analyses from large controlled, clinical trials cast new light previously held beliefs about utility genotyping predicting effectiveness improved cancer outcomes in early-stage, cancer.
