Associated Genetic Biomarkers

Overview

NCI Definition: An infiltrating lobular adenocarcinoma of the breast. The malignant cells lack cohesion and are arranged individually or in a linear manner (Indian files), or as narrow trabeculae within the stroma. The malignant cells are usually smaller than those of ductal carcinoma, are less pleomorphic, and have fewer mitotic figures. [1]

Breast invasive lobular carcinomas most frequently harbor alterations in CDH1, PIK3CA, TP53, CCND1, and ERBB2 [2].

Most Commonly Altered Genes in Breast Invasive Lobular Carcinoma

PIK3CA Mutation, CDH1fs, CDH1 Mutation, PIK3CA Codon 1047 Missense, and PIK3CA H1047R are the most common alterations in breast invasive lobular carcinoma [2].
