Breast cancer incidence in a large cohort of Peruvian women affiliated to a pre-paid system.

e12566 Background: Prostate cancer (PC) is the most common malignancy and the leading cause of death by cancer in Peruvian men (age-standardized rate [ASR] of 37 new cases/100,000 men estimated by GLOBOCAN 2008). The purpose of this study was to assess the incidence of PC in a cohort of men at Oncosalud, an oncologic pre-paid system that currently has 600,000 affiliates. Methods: We evaluated a dynamic cohort (period 1989 to 2011) of men affiliated to Oncosalud – Auna, an oncologic prepaid system.The crude incidence rate per year (number of new cases/men at risk), the specific rate according to age (number of new cases / persons-year), and cumulative risk were calculated. Results: Overall, during the assessment period, the PC incidence rate per year was 183.7 and the ASR incidence was 145 per 100,000 affiliates respectively. In our cohort of affiliates there were no PC cases before 1995 (with 3061 men at risk for that year). The highest incidence rate was 160.5 registered in 1999 (12,461men at risk). Inci...
