[Screening for cervix carcinoma--a retrospective comparison between new and established federal German states].
OBJECTIVE
There is no doubt about the effect of cytological screening programmes on the reduction of incident cases with invasive cervical carcinoma. The question is, to what extent this reduction was caused by cytological screening exclusively. A retrospective analysis of the former East German cytological mass screening could give information of early and late screening effects and also on the efficacy. Based on data from the Saarland cancer registry, common aspects and differences between the old and new federal states of Germany can be addressed regarding incidences and mortality trends for cervical carcinoma.


RESULTS
Since the sixties the incidence of CIS has increased by 625% while the incidence of invasive carcinoma has decreased by 44% in the new federal states. Since the seventies mortality due to cervical carcinoma decreased by 44%. Incidences and mortality rates of the Saarland were considerably lower than of the new federal states.


CONCLUSIONS
This study describes noteworthy early screening effects and proves the efficacy of mass cancer screening. Changes of incidence and, particularly, mortality rates are not exclusively due to these programmes.
