Figure 3From: Luminal A and luminal B (HER2 negative) subtypes of breast cancer consist of a mixture of tumors with different genotypeThe relationship of subtypes to the DNA ploidy and CIN. The diploid/CIN- status was detected in 72 (64.9%) of the 111 luminal A carcinomas, 39 (41.1%) of the 95 luminal B (HER2-) carcinomas, 8 (11.6%) of the 69 lumminal B (HER2+) carcinomas, 2 (4.9%) of the 41 HER2 carcinomas, and 8 (17.0%) of the 26 basal-like carcinomas. In contrast, the aneuploid/CINā+āstatus was detected in 31 (27.9%) of the 111 luminal A, 47 (49.5%) of the luminal B (HER2-), 56 (81.2%) of the 69 luminal B (HER2+), 37 (90.2%) of the 41 HER2, and 36 (86.6%) of the 47 basal-like subtype tumors. The incidence of diploid/CIN- and aneuploid/CIN+ status was different between the luminal A subtype and luminal B (HER2-), luminal B (HER2+), HER2, and basal-like subtypes (pā=ā0.0006, pā=ā5E-13, pā=ā5E10-12, and pā=ā8E10-9). In addition, the incidence of diploid/CIN- and aneuploid/CIN+ status was statistically different between the luminal B (HER2-) subtype and luminal B (HER2+), HER2, and basal-like subtypes (pā=ā0.00002, pā=ā0.000009, and pā=ā0.002).
