Five year RS of female breast cancer patients (ICD-10: C50) from Saarland estimated for the calendar period 2005–2009 by age and tumor characteristics. 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 estimates, age standardized estimates of 5-year RS were derived using the ICSS weights; b) cases without microscopic verification were excluded.
