Title:
ERBB2 and PTPN2 g ene copy numbers as prognostic factors in HER2-positive metastatic breast cancer treated with trastuzumab
Excerpt:
Patients with tumours displaying a high-grade ERBB2 (HER2) amplification level of ≥6 copies had a significantly improved overall survival hazard ratio [(HR)=0.4; 95%, confidence interval (CI): 0.2-0.9] and progression-free survival (HR=0.3; 95% CI: 0.1-0.7) compared with patients with tumours harbouring fewer ERBB2 copies.
