Steroid receptors, cellular kinetics, and lymph node status as prognostic factors in breast cancer

Abstract

Steroid receptor status, cellular kinetics, abnormal proto-oncogene presence, and lymph node metastases all have been shown to provide prognostic information in breast cancer. The factors guide the choice of therapy and predict the course of the disease. Both disease-free survival and overall survival are predicted by these variables. Steroid receptors are the most reliable predictor of hormonal responsiveness. Lymph node involvement is crucial in determining the extent of the disease and the need for adjuvant therapy. Cellular kinetics and abnormal proto-oncogene presence predict tumor aggressiveness. Together these prognostic factors provide considerable information to the clinician.
