Abstract

Objective: To describe the occurrence and survival patterns of childhood cancer patients over the last 20 years in Cali.
Methods:Information was obtained from the Cancer Population Registry in Cali and the Municipal Department of Health. The International Classification for childhood Cancer (ICCC) was used. Vital status data was obtained from MDH death certificates and hospital databases. Additionally, clinical records were reviewed and, in some cases, telephone contact was made to gather data. Follow-up was completed until December 31, 2011. Incident (IR) and mortality rates (MR) were estimated and adjusted for age. Life-tables were made to estimate overall survival.
Results: Between 1977-2011 there were 2,311 cases of cancer identified in children less than 15 years of age. The IR and MR for Cali were found to be 141.2 and 55.6 per million of people per year. Leukemias, lymphomas, Central nervous system (CNS) tumors and soft tissue sarcomas showed IR´s of 60.1, 20.5, 25.7 and 9.4, respectively. 5-years OS was 48%, and showed an improvement from 24.9%±4.3 to 51.8%±4.6, compared 1992-96 vs 2002-06 periods.
Conclusion: The IR found is comparable with those from affluent countries. Taking into account that pediatric cancer is curable in about 75-80% of the cases, an enormous challenge is presented to the Colombian health system: to improve current clinical results.

 es Epidemiología descriptiva de cáncer infantil en Cali, Colombia 1977-2011
Bravo, Luis Eduardo; García, Luz Stella; Collazos, Paola; Aristizabal, Paula & Ramirez, Oscar

Resumen

Objetivo: Describir los patrones de ocurrencia y supervivencia por cáncer infantil en los últimos 40 años en Cali, Colombia.
Métodos: La información fue obtenida del Registro Poblacional de Cáncer de Cali y el estado vital de las bases de datos de mortalidad de la Secretaría de Salud Pública Municipal (SSPM) y de los egresos hospitalarios. Se utilizó la clasificación internacional de cáncer infantil versión-3. El seguimiento se hizo hasta el 31/12/2011. Se estimaron las tasas de incidencia (TI), mortalidad (TM), se ajustaron por edad y se realizó un análisis de período para la sobrevida global (SG).
Resultados: Se identificaron 2,311 casos en <15 años entre 1977-2011. Las TI y TM fueron de 141.2 y 55.6 por millón de personas-año. Leucemias, linfomas, tumores del SNC y sarcomas de tejidos blandos mostraron TI de 60.1, 20.5, 25.7 y 9.4 por millón de personas-año, respectivamente. La SG a 5 años fue 48%, al discriminar por quinquenio mostró una mejoría de 24.9%±4.3 al 51.8%±4.6, al comparar los periodos 1992-96 vs 2002- 2006.
Conclusión: La TI encontrada es comparable con las descritas en EEUU y Europa, sin embargo, la supervivencia es menor. Como el cáncer infantil es curable en alrededor del 75-80% de los casos, se plantea un gran reto para el sistema de salud Colombiano, mejorar los resultados actuales.
