This study, focusing on premenopausal non-distant metastatic breast cancer patients treated with taxane chemotherapy, demonstrated that some SNPs involved in docetaxel pharmacogenomics may impact breast cancer recurrence and/or mortality, especially SLCO1B1 rs2306283, GSTP1 rs1138272, and CYP3A rs10273424. Here, SLCO1B1 is linked to breast cancer.
