[Prognostic and predictive factors in breast cancer].

Recent data on prognostic and predictive significance of breast cancer-associated molecular markers are presented and their clinical value in making individual prognosis and choosing adequate therapy is discussed. Markers of tumor proliferation, steroid hormone receptors, factors of epidermal cell growth, plasminogen activators and inhibitors, factors influencing angiogenesis and apoptosis and genome characteristics are considered. It is concluded that only Ki-67, ER, PR and Her-2/neu may be recommended for clinical use.
