CYP2D6 genotype is an inherited factor that alters the metabolism of tamoxifen. “The goal of the CPIC Guideline for CYP2D6 and tamoxifen therapy is to provide clinicians information that will allow the interpretation of clinical CYP2D6 genotype tests so that the results can be used to guide prescribing of tamoxifen when genotype information is available,” says Matthew Goetz, M. D., a Mayo Clinic medical oncologist, who is the lead author. “The consensus of the consortium tamoxifen group was that there was sufficient evidence to use CYP2D6 genotype to assist with clinical recommendations for women who are being considered for tamoxifen for early stage estrogen receptor positive breast cancer.” Tamoxifen is converted through the process of liver metabolism into forms that result in greater anti-estrogenic potency and anti-tumor activity than the parent drug. Antiestrogens are a class of drugs which prevent estrogens from mediating their biological effects in the body.
