Title:
ABCB1, FCGR2A, and FCGR3A polymorphisms in patients with HER2-positive metastatic breast cancer who were treated with first-line taxane plus trastuzumab chemotherapy
Excerpt:
PFS was significantly longer in ABCB1 1236CC and/or 2677TT carriers compared to the others (p = 0.006)...Our data support that ABCB1 polymorphisms may predict PFS after first-line TH chemotherapy in patients with HER2-positive MBC.
Secondary therapy:
Chemotherapy
