[Histological typing of the breast by multifocal biopsies].
The current concept of high risk mastopathy was revolutionised by the work of Dupont and Page (1985), who demonstrated the importance of proliferative mastopathies in the assessment of the risk, particularly when they are associated with epidemiological factors. Based on these data, the Montpellier breast pathology study and research group (GERPAMM) developed on original method designed to define the precise histological profile of women considered to be at risk of breast cancer, despite the absence of any focal mammographic signs. This typing, consisting of a rigorous surgical protocol strictly complying with Page's histological definitions, was performed in women presenting a certain risk defined by clinical, cytological and radiological criteria (density and disseminated microcalcifications). This paper presents a preliminary review of 6 years' experience in 162 cases. The preliminary results confirm than many cases of atypical hyperplasia are not associated with a focal mammographic abnormality. However, in the absence of focal signs, certain types of disseminated microcalcifications with a morphological appearance suggestive of an intraductal origin, are significantly associated with high-risk histological signs. Histological typing is therefore useful to predict the cancer risk, to dedramatise cases without significant hyperplasia and to propose an adapted and justified approach to cases with a high histological risk.
