Five year RS of female BRC patients (ICD-10: C50) from Saarland estimated for the calendar period 2005–2009 by age, tumor stage and local treatment. N: number of patients contributing survival experience; RS: point estimate of 5-year relative survival; SE: standard error of RS; a) except for age group-specific survival, age standardized estimates were derived using the ICSS weights; including patients with microscopically verified tumors and available information on age and stage and the respective local treatment; patients presenting with distant metastases or DCO notified tumors were excluded.
