[Prognostic factors in medullary breast cancer].
In 55 patients with medullary carcinoma of the breast follow-up data over an average period of 68.1 +/- 35.3 months were recorded. The histological slides of all tumors were retrospectively classified according to the same criteria. The parameters registered were: tumor-size, histological grading, receptor status, necrosis of tumor tissue, cellularity of the stroma, status of axillary nodes, reactive changes of axillary nodes and tumor invasion of lymphatic vessels. The importance of each parameter registered for disease-free survival and overall survival was calculated statistically using the log-rank-test. Of all parameters, only the nodal status of the axilla proved prognostically significant. Metastases of axillary nodes were demonstrable in only 31% of all MC. The incidence of nodal involvement proved to be less than in non medullary breast cancers. In 15 (27.3%) of the patients, progression of the tumor occurred. All women with distant metastases i.e. 12 (21.8%) died of the disease, whereas patients with only local recurrence of breast cancer are still alive. 72.7% of the patients showed relapse-free survival. Other parameters of proven prognostic value in breast cancers like receptor status and histological grading were of no relevance to the survival in MC. Prediction of prognosis depends on the correct classification of the tumor subgroup according to strict microscopical and macroscopical criteria.
