This relationship did not reach statistical significance for the individual AUS-ILC (p <0.06) or HK-ILC cohorts (p <0.09) with respect to tumor size, perhaps reflecting lower numbers relative to IDC counterparts, nor for the AUS-ILC cohort with respect to HER2 status (p =0.28); however, the latter value reduced to p =0.06 following age correction, suggesting confounding due to very low numbers (one case only) of HER2-positive ILC in the older AUS cohort. Here, ERBB2 is linked to neoplasm.
