How the population-based cancer registry of Cali, running since 1962, finds and codes every new cancer in the city's residents, and the quality measures that let its data appear in the international reference volumes.
The Population Cancer Registry of Cali (RPCC) has operated since 1962. New cancers in permanent residents of Cali are collected by active search in, and notification from, hospitals and public and private laboratories; the municipal health secretariat provides individual data on general and cancer mortality. Tumours are coded with ICD-O-3 and deaths with ICD-10; rates are age-standardised, trends are assessed with joinpoint regression and five-year net survival with the Pohar-Perme estimator.
Cali's registry is one of the four whose data Colombia's national cancer institute uses to estimate cancer for the whole country, so the quality of its methods underpins the national figures.
