All 4 models consistently rank ER+/HER2−, ER−/HER2+, radiographic tumor size, and BPE as top predictors of OS (AUC = 0.83–0.84), (5) pCR, and certain tumor subtype, and private insurance status are associated with higher survival probability, (6) when grouping race and ethnicity by tumor subtypes, neither pCR nor OS outcomes was different due to race and ethnicity for each tumor subtype. The gene discussed is ERBB2; the disease is neoplasm.
