From: PIK3CA mutations are common in lobular carcinoma in situ, but are not a biomarker of progression
a Summary of copy number changes in pure classic lobular carcinoma in situ (pure-cLCIS), classic lobular carcinoma in situ associated with invasive lobular cancer (inv-cLCIS) and classic lobular invasive cancer (cILC). b Two-way hierarchical clustering of the pure-cLCIS, inv-cLCIS and cILC based on type of somatic copy number aberration (SCNA) (=/>100 probes) occurring on each p and q arm. (cnLOH = copy neutral loss of heterozygosity)
