This is the first observational study in which adjustments for a comprehensive set of prognostic factors, adjuvant therapies, mode of detection, and comorbidities were possible to investigate OS, BCS, as well as recurrence risk of patients undergoing BCT + RT, MT + RT, or MT.Women aged 50-74 years at diagnosis of early-stage invasive breast cancer (I-IIIa) between 2001 and 2005 at the German population-based case-control study (MARIE study) were recruited and followed prospectively as a case cohort until 2015. Kaplan-Meier estimates and stepwise adjusted multivariable Cox models were used to estimate hazard ratios (HRs) and 95 %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:29556781 %R 10.1007/s10549-018-4754-6 %U https://inrepo02.dkfz.de/record/136819
