Defossez G, et al. - Researchers determined the influence of the participation in screening programme according to the mode of detection on the early diagnosis, treatment, and specific survival outcomes in women with breast cancer. Using the Kaplan–Meier method and Cox proportional hazard models, specific survival rates were assessed in three groups of breast cancer patients: the screening programme (SP), interval cancer (IC), and non-screening programme detected cancer (NSP) groups. Relative to screen-detected cancers, more aggressive features were shown by interval cancers. However, compared to non-screen detected cancers, interval cancers were diagnosed at a less advanced stage. Early treatment seemed to benefit women who participated in the screening process despite having cancers missed by the screening programme.
