Abstract

Effectiveness of organised (service) and opportunistic mammography screening in Switzerland was evaluated for thefirst time, based on internationally recognised prognostic indicators. Effectiveness by screening type (organised vs opportunistic screening) and detection modality (screened / unscreened women) was examined for 3 cantons (Vaud, Valais, Geneva) with organised programmes. Comparisons of prognostic profile were drawn with 2 regions (St-Gall/Appenzell and Ticino) uncovered by service screening, of low and high prevalence of opportunistic screening, respectively.
Opportunistic and organised screening yielded little difference in breast cancerprognostic profile. Both screening types led to substantial stage shifting.Breast cancer prognostic indicators were systematically more favourable in cantons covered by a programme. In regions without a screening programme, the higher the prevalence of opportunistic screening, the better the prognostic profile.
Organised screening appeared as effectiveas opportunistic screening in Switzerland. The favourable influence of mammography screening on stage distribution augurs a screen-attributable decline ofbreast cancer mortality. Extension of organised mammography screening to the whole of Switzerland can be expected to further improve breast cancer prognosis in a cost-effective way.
