Predictors of state-of-the-art management of early breast cancer in Switzerland

Background: The aim of this study was to investigate predictors of state-of-the-art management of early breast cancer in Switzerland. PATIENTS AND METHODS: The study included 3499 women aged 25-79 years diagnosed with invasive breast cancer stages I-IIIA in 2003-2005.
