Incidence and mortality rates from breast cancer in the metropolitan area of Bucaramanga from 2001 to 2005

Abstract

Introduction: The breast cancer is a public health problem worldwide; that is why to know the incidence and mortality rates in our region is a priority to an overall assessment of the health and disease secondary status to this tumor lesion. Objective: to describe the incidence and mortality rates of breast cancer in women from the Metropolitan Area of Bucaramanga (MAB) during the first five years of operation of the Cancer Population Registry at MAB (MAB-RPC). Methodology: The cases of invasive breast cancer, primary in women, diagnosed during the period 2001-2005 were selected based on RPC-AMB. The population and mortality data were obtained from the National Administrative Department of Statistics (NADS), Secretary of Health and National Registry of the Nation. Similarly, Total and specific crude incidence rates (TC) and mortality (TMC) by age and incidence rates (TEE) and mortality (TMEE) for the corresponding five standardized by the direct method were estimated. Results: 999 cases of invasive breast cancer were identified. Eleven patients were excluded from analysis after completing the second validation process. The overall TC was 37.8/100.000 women and the overall TEE was 38.9/100, 000 women. The overall TMC rate was 17.3/100.000 women and the TMEE was 17.5/100, 000 women. The cumulative mortality rate of 5 years due to breast cancer for the cohort was 44.4% (95% CI 41.2-47.6). The sum of follow-up time was 72520.6 months or 6043.4 years, with an interquartile range of (37.9-114.6). The incidence density rate was 4.32 deaths from invasive breast cancer every 1000 women per month of follow-up (95% CI 3.9-4.8). As the incidence density increased for patients under 44 with 4.55 (95% CI 3.61-5.73) and for women over 65 years with 6.18 (95% CI 5.06-7.55). Conclusion: This report globally determines scope of the control measures of the breast control problem in our region and also suggests some difficulties in early diagnosis and its appropriate treatment. Death rates from breast cancer at the MAB were higher in patients over 65 than patients under 44 years. Therefore, it is necessary to deepen into the determinants of mortality in these two population groups.[Osma-Zambrano SE, Uribe-Pérez CJ.
