[Experiences of the Bavarian mammography screening program]

The Bavarian Mammography Screening Program started in April 2003. A detailed analysis of the consistency of diagnosis in the evaluation of vacuum-assisted stereotactic or core needle breast biopsies is presented. A total of 32 pathologists participated in a blinded evaluation of the biopsies. Each case was evaluated independently by two participating pathologists. A total of 1,357 cases were reviewed. The histopathological reports of the biopsies made by the two consulting pathologists were compared. The concordance rate of the first and second consulting pathologist was 93% for the B-classification. In general, the level of diagnostic agreement was very high for well defined, benign and malignant lesions. Some of the discrepancies resulted from the incorrect application of the B-classification. Discrepancies in the reports were also due to divergent interpretation of benign and "borderline" lesions. The protocol for the blinded evaluation of breast biopsies in two rounds assured a high level of quality. In conclusion, prerequisites for the success of a mammography screening program are interdisciplinary consensus conferences and audit rounds involving pathologists.     «
