[Grading intraductal breast carcinoma].

Mammographic screening has led to increased detection of intraductal carcinoma of the breast (IdC). IdC is y heterogeneous disorder with different clinical outcomes. The study was designed to confirm consensibility of the three-tiered classification, accepted by Thomas Jefferson University Consensus Conference since 1997. The study population comprised 30 patients with IdC including patients with T1 mic and T1a. Sixty percent of IdC were classified as II-nd grade, 27% were III-rd grade and 13% as I-st grade. 20% of IdC exhibited heterogenity of grade. The cases with cribriform and papillary architecture were 1-st or II-nd grades. The other cases with comedo and solid architecture we are II-nd or III-rd grades. The cases with invasive component (T1 mic u T1a) were 25%--I-st grade, 75%--II-nd grade and III-rd grade--87.5%. In conclusion, the grading of IdC could y prognostic factor in far long term prognosis of patients with those lesions.
