Of considerable interest, we found that Hispanic patients had higher rates of ERBB2-zero TNBC than ERBB2-low TNBC, which is unlike the higher rates of ERBB2-low BC seen overall in our study and across other studies.4,5,6,7 Although few studies have assessed the prevalence of ERBB2-low BC by race and ethnicity, Peiffer et al5 similarly demonstrated that Hispanic patients had lower odds of ERBB2-low BC (OR, 0.85; 95% CI, 0.83-0.86; P < .001) compared with White patients. Here, ERBB2 is linked to breast cancer.
