Abstract
IntroductionThe incidence trend, characteristics and prognosis of breast cancer could differ by age group. The main objective was to describe the evolution of breast cancer incidence in women aged ≥75 years and to estimate survival rates MethodsA cohort study was set-up using data from a population-based cancer registry. Standardized incidence rates were computed during the 1989–2012 period. Ten-year net survival rates were estimated using cases diagnosed. ResultsA total of 3,523 breast cancers were diagnosed. The average annual increase of incidence rates was 7.9% (95% CI: 4.8–11.1%) and 1.1% (95% CI: 0.6–1.6%) for in situ and invasive breast cancers, respectively. Ten-year net survival rate was lower for women aged ≥75 years (67% (95% Cl: 61–74%)) compared to women aged 50–74 years (82% (95% CI: 81–83%). ConclusionA greater disease severity at the time of diagnosis, and less effective treatments given to elderly patients are the most plausible explanations for lower survival.
