Intratumoral Heterogeneity of HER-2/neu in Invasive Mammary Carcinomas Using Fluorescence In-Situ Hybridization and Tissue Microarray
1 Oct 2006
Abstract excerpt
Fluorescence in-situ hybridization is increasingly being used to determine HER-2/neu status in patients with breast carcinoma. The possibility that intratumoral heterogeneity of HER-2/neu gene amplification may potentially contribute to inaccurate assessment of HER-2/neu status was investigated in routine cases of invasive mammary carcinomas. From 169 representative formalin-fixed, paraffin-embedded blocks of...
