Fig. 3From: Breast carcinomas with low amplified/equivocal HER2 by Ish: potential supporting role of multiplex ligation-dependent probe amplificationAssociation between HER2 s/n and immunophenotypical factors. The 64 breast carcinomas presenting 4.0ā5.9 HER2 s/n included in our study have a significantly higher percentage of estrogen (pĀ =Ā 0.016) and/or progesterone (pĀ =Ā 0.001) positivity, and a lower percentage of Ki67 proliferation index (pĀ =Ā 0.027) than highly amplified tumors (ā„6.0 HER2 s/n)Back to article page
