Abstract: | Summary The immunohistochemnichally determined receptor status, as well as first-generation risk factors (tumor size, lymph node status, histologic grading including subfactors, tumor histology, and biochemically determined receptor status) were prospectively analyzed in 288 cases of primary breast cancer for their impact on recurrence-free survival (RFS) and overall survival (OS) after a median observation period of 41 months.Immunohistochemically (ER-ICA) and biochemically determined estrogen receptors (ER-DCC), as well as tumor size, lymph node status, histologic grading, mitotic rate, and nuclear polymorphism, were of prognostic value for recurrence-free survival and/or overall survival.In multivariate analysis, lymph node status, tumor size, and mitotic rate proved to be independent prognosticators; ER-ICA showed significance in the univariate analysis which dropped, however, when multivariate analysis was applied.The prognostic power of histologic grading in our series seemed to depend mainly on the subfactors which relate to nuclear features. |
