[Correlation of estrogen receptors and histologic and cytologic grading of breast cancer]

Correlations between estrogen receptors and other prognostic criteria have been examined. These criteria are clinical extent, status of lymph nodes, histologic differentiation, histologic and cytologic grading. Cancers with a good prognosis are much more receptor positive than those with a bad prognosis. The quantity of receptors does not allow any prognostic statement. Possible reasons for it are discussed.
