Abstract

ABSTRACTOBJECTIVE To describe the trend in cancer mortality rates in Brazil and regions before and after correction for underreporting of deaths and redistribution of ill-defined and nonspecific causes.METHODS The study used data of deaths from lung cancer among the population aged from 30 to 69 years, notified to the Mortality Information System between 1996 and 2011, corrected for underreporting of deaths, non-registered sex and age , and causes with ill-defined or garbage codes according to sex, age, and region. Standardized rates were calculated by age for raw and corrected data. An analysis of time trend in lung cancer mortality was carried out using the regression model with autoregressive errors.RESULTS Lung cancer in Brazil presented higher rates among men compared to women, and the South region showed the highest death risk in 1996 and 2011. Mortality showed a trend of reduction for males and increase for women.CONCLUSIONS Lung cancer in Brazil presented different distribution patterns according to sex, with higher rates among men and a reduction in the mortality trend for men and increase for women.

Summary

Introduction

Cancer is a public health issue and ranks second in mortality around the world; in some developed countries, it has become the first leading cause of deatha. According to the World Health Organization (WHO), in 2012 there were approximately 1.8 million new cases of lung cancer, or 13.0% of total cancer, of which 58.0% occurred in developing countries. It is estimated that growth rates grows 2.0% every yearb. The five-year survival rate for this disease ranges from 13.0% to 21.0% in developed countries, and from 7.0% to 10.0% in developing countries. Overall differences are greater in incidence, mortality and survival, and, in general, geographic patterns of mortality accompany those related to incidenceb. In Brazil, lung cancer is the leading cause of death from cancer among men and the second among women. In 2011, it caused 22,424 deaths in all ages, 13,698 among men and 8,726 among womenc
