[Quality rating of follow-up examinations conducted on breast cancer patients].

For breast centre certification, follow-up care data have to be presented, although the further treatment is carried out outside of the hospital. An analysis of 2062 patients with their first operation (breast cancer and carcinoma in situ) occurring between 1.1.1984 and 31.12.1998 has been conducted. The tracking of follow-up results ended on 1.7.2007. The survival of breast cancer patients appears to be superior in the pure clinical register than with cross-linking with additional registers (Epidemiological Cancer Register and registration of address office). The outcome of this is that the completed feedback of the cases of death (Cancer Register) and of living patients (registration of address office) increases the qualitative statement. The compliance with the data security laws may be ensured by pseudo-anonymisation. Georg Thieme Verlag Stuttgart, New York.
