s / The Breast 20 (2011) S12–S55 S45 underlying incidence (from year 0) was calculated. Late-stage breast cancers were defined as pT2-4. Results: In year 1, the incidence ratio of late-stage breast cancers was 1.11 (95% CI 1.00-1.22). After decreasing to values next to unity in years 2 and 3, the ratio showed a weakly significant reduction in years 4 (0.91; 0.811.01) and 5 (0.88; 0.79-0.99). A significant and stable reduction was observed in years 6 (0.79; 0.70-0.90), 7 (0.77; 0.67-0.89), and 8 (0.79; 0.67-0.93). Discussion: Starting from the 6th year of screening, the incidence of latestage breast cancers decreased by slightly more than 20%. This observation predicts a mortality reduction and is consistent with the results of other evaluations from the same programmes. |
