[The prognosis of ductal invasive breast carcinoma in histopathology].
A simple classification of ductal breast carcinoma, consisting of the low, intermediate and high malignancy categories is proposed. The tumour subtypes, categorized according to WHO classification, were sorted into prognostically different subgroups, taking the modified Bloom's grading score and previously published histological studies into account. The low grade category includes papillary, cribriform, tubular, colloid and typical medullary (with the lymphoid stroma) carcinomas. The intermediate group consists of ductal not otherwise specified and mixed ductal/lobular tumours. The high grade category includes atypical medullary, comedo and mucin producing carcinomas. This classification is fully compatible with the commonly adopted ICD-O (1990) morphologic terminology. It should simplify the histological reporting of breast cancer so that the results were as reproducible as from the working formula of malignant lymphomas.
