Abstract:
Objective To study the expression and significance of CD10, SMA, P63 on human breast myoepithelial cells. Methods SP immunohistochemical method was used to examine the expression of CD10, SMA, P63 on human breast myoepithelial cells from 68 breast diseases samples, including breast fibroadenoma, breast fibroadenesis, breast atypical ductal hyperplasias, ductal carcinomas in situ and breast invasive carcinomas. Results 2 +/3 + circumferential CD10, SMA and P63 staining of MEC was seen in 10 patients with breast fibroadenoma, breast fibroadenoma and 13 patients with atypical ductal hyperplasias. In an analysis of total ducts by 15 patients with breast ductal carcinomas in situ, 3 + circumfenrential staining was seen in 92 of 384 ducts(23.96%) stained for CD10 versus 185 of 384 ducts (48. 18%) stained for SMA and 80 of 384 ducts(20. 83%) stained for P63. All differences among percentage positively stained of these three antibodies was significant, p-values was lower 0. 05. MECs were not found with immunohistochemistry in 170 of 384 duets (44. 27%)with anti-CD10,74 of 384 ducts(19.27%) with anti-SMA and 127 of 384 ducts(33.07%) with anti-P63. MECs were not found with CD10,SMA and P63 in 30 patients with breast invasive carcinomas. Conclusion We concluded that CDIO could be another useful marker of breast myoepithelial cells after SMA and P63. It provided more sophisticated information about presence or absence of breast myoepithelial cells in confusing breast lesions.
