Official title:
Observational Study: Biomarker Research for Tamoxifen Pharmacogenetics Among Asian Breast Cancer Patients
The clinical outcome of tamoxifen treatment in breast cancer patients may be influenced by the activity of cytochrome P450 enzymes involving in tamoxifen biotransformation.
The investigators investigated the prognostic and/or predictive value of genetic polymorphisms of enzymes involved in tamoxifen metabolism for the treatment outcome among Asian breast cancer patients. ;
Observational Model: Case-Only, Time Perspective: Retrospective
