[Prognostical factors of breast neoplasms without metastasis. Synthesis by a multifactoral analysis]

Multifactorial analysis by dichotomous split was applied to a consecutive series of 541 female breast cancer patients without detectable metastasis at onset of treatment. These patients were entirely treated in the same institution (Fondation Bergonié), in the years 1960-1974. This multifactorial analysis sets a hierarchical order among the different prognostic factors and defines groups of patients homogeneous for metastatic risks. The significant prognostic factors in these series are : number of malignant axillary nodes; location and size of tumour; state of adjacent skin; relations with thoracic wall; pre or post-menopausal status; inflammatory signs; thermographic and mammographic data.
