Background: Breast cancer is the most common malignant tumor in women in the world. In 2005, it was incorporated to the Explicit Guaranties Health System (GES) in Chile. Aim: To describe the demographic and clinical characteristics of breast cancer patients and to determine the effect of incorporating these women to GES. Material and Methods: Medical records of 5,119 women with breast cancer aged 59 ± 14 years, attended at six public hospitals between 2000 and 2010 were reviewed. Median follow up was 87 months (range 1-182). Mortality was assessed using death certificates obtained at the National Identification Registry. Results: Sixty six percent of women were in stage I-II, 29% in stage III and 5% in stage IV. Surgery was performed in 4023/5119 cases (79%), adyuvant radiotherapy in 3627/4517 cases (80%), chemotherapy in 3,204/3,424 cases (94%) and hormone therapy in 1,695/2,375 cases (71%). Between 2000 and 2010, there was a significant increase in the proportion of cases in stage I, from 8% to 25%, (p < 0.01). Overall survival (OS) increased 1% per year, since the beginning of GES system (p = 0.024). Five year OS was 75.1%. The figures for Stage I, II, III and IV were 93, 84, 62 and 27% respectively (p < 0.01). Patients without lymph node involvement and who were not triple negative, had a significantly better OS. Conclusions: There was a significant increase in stage I cases, and a 1% per year OS improvement after GES system started, compared with the previous period.
