%X Introduction. Population-based cancer registries are aimed to provide information of vital importance in planning, prevention and cancer management. Information generated by the registries must be comprehensive, valid and comparable. Therefore, it is recommended to make regular quality assessments. Objective. To describe the quality of cancer incidence data at four population-based cancer registries in Colombia for cancer incidence estimations in Colombia. Material and methods. Data collected at population-based cancer registries of Bucaramanga, Cali, Pasto, and Manizales, was included. Completeness was assessed through the graphic description of mortality incidence ratios and their relation to the survival. Validity was studied through the description of morphologically verified cases, cases identified from death certificates only, and the internal consistency of the data. Results. There was a global under-coverage of cancer registration at Bucaramanga and Manizales, while a more specific under-coverage for certain localizations was observed in Cali and Pasto. Validity analyses established a low use of death certificates as a source of information and some inconsistencies among valid basis of diagnosis and morphology. Conclusions. In Colombia, the data quality at population-based cancer registries can be further improved by considering the use of additional sources of information such as death certificates, and the use of specialized software for data capture and automatic validation of internal consistency. Mortality certification must be improved in areas where operating a population-based cancer registry. Introducci車n.

Evaluar algunos aspectos relacionados con la exhaustividad y la validez de la informaci車n recolectada por los registros poblacionales de c芍ncer en Colombia para estimar las cifras de c芍ncer en Colombia. Materiales y m谷todos. Se evalu車 la informaci車n de los registros poblacionales de Bucaramanga, Cali, Pasto y Manizales. La exhaustividad se analiz車 a trav谷s de las razones de mortalidad incidencia y su relaci車n con la supervivencia. La validez se estableci車 con la descripci車n de los casos verificados morfol車gicamente y los registrados en certificados de defunci車n. Finalmente, se describieron las inconsistencias generadas.
