The pathological characteristics on the familial breast cancers are presented in Table 2. Invasive ductal carcinoma (IDC) was probably the most typical histological variety within the three groups. Ductal carcinoma in situ (DCIS) and invasive lobular carcinoma had been significantly less frequently observed in BRCA1 mutated breast cancers (p = 0.061). Although the differences had been not statistically important, there have been more DCIS instances among sufferers with BRCA2 mutated breast cancers (28.6 ) than among these with BRCA1 (3.2 ) and non-BRCA1/2 (15.0 ) mutations. IDCs with BRCA1 mutation showed highhttp://ejbc.krer nuclear grade than these with BRCA2 or non-BRCA1/2 mutations (p 0.001). Furthermore, BRCA1 tumors have been additional often ER damaging, PR unfavorable, HER2 unfavorable, CK5/6 good, and displayed a high proliferation index of Ki-67 compared with BRCA2 and non-BRCA1/2 tumors.
