ERBB2 and breast carcinoma: For instance, a 4-Corners Breast Cancer-based study that only included 285 women (NHWs=119 and Latinas=69) reported a higher prevalence of HER2-positive tumors in Latinas compared to NHWs (31.9% vs 14.3%, p<0.001, respectively), and a higher likelihood of having HER2-positive tumors for this population group (OR=2.48, 95% CI, 1.10-5.58) in a model adjusted for age and tumor characteristics (33).
