Abstract (English):	Objective Mortality study is useful for the estimation of cancer incident cases; but a quality assessment of the mortality information is required previous to the process of cancer incidence estimation. The aim of this study is to evaluate the quality of death-certification in Colombia. Materials and methods Overall quality of death certification and quality of cancer mortality certification was analyzed for the period 2002-2006. Classic validity indexes were described through simple percentages for each district and four cities, where operating populalJon-based cancer registries: Bucaramanga, Call, Manizales, and Pasto. A principal component analysis was performed in order to identify relationships that might not be evident in the descriptive analysis. Results 952 104 registries were analyzed, 150 163 corresponding to cancer deaths. A high quality index was observed for overall death certification, with 92.8 % of the overall mortality propedy certified. Most errors were due to ill defined causes of death. A high quality index was also observed for cancer death registration with 91.5 % of the cancer deaths properly certified. Ill-defined, secondary and unspecified cancer sites certification prevailed as the most frequent causes of error. Conclusion Colombia has high quality standards for overall death and cancer death certification. Mortality data can be used confidently in the cancer incidence estimation process, without requirements for any specific corrections. [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	Objetivo El estudio de la mortalidad resulta útil en la estimación de casos incidentes de cáncer, sin embargo se requiere evaluar la calidad de la certificación de la mortalidad antes de proceder a hacer las estimaciones de incidencia. El objetivo de este estudio es evaluar la calidad de la certificación de la mortalidad en Colombia. Materiales y métodos Se analizó la calidad de la certificación de la mortalidad general y por cáncer en Colombia en el quinquenio 2002-2006. Se describieron indicadores clásicos de validez por medio de porcentajes simples para cada Departamento y además para cuatro áreas en donde operan registros poblacionales de cáncer (el area metropolitana de Bucaramanga y las ciudades de Cali, Manizales y Pasto). Se realizó un análisis de componentes principales con el fin de identificar relaciones no evidentes en el análisis descriptivo. Resultados Se analizaron 952 104 registros de defunción dentro de los cuales había 150 163 muertes por cáncer. El 92,8 % de la mortalidad general estaba bien certiflcada. Predominaron los errores debidos al mal diligenciamiento. El 91,5 % de la mortalidad por cancer estaba bien certificada. Predominaron los errores debidos a la mala definición de la localización del tumor primario como causa de defunción. Conclusión La calidad de la certificación de la mortalidad general y por cáncer en Colombia es buena y ante la baja magnitud de problemas en la certificación, se puede emplear los datos de mortalidad en las estimaciones de incidencia de cáncer, sin aplicar más correcciones que las que se hacen de manera estándar.
