RESUMEN

Introducción:

Existen pocas investigaciones sobre factores de riesgo de tumores renales pediátricos.

Objetivo:

Caracterizar en detalle regiones geográficas de alta incidencia de tumores renales pediátricos en el centro de Argentina y su posible vinculación con factores de riesgo genéticos.

Métodos:

El área de estudio comprendió la provincia de Córdoba (Argentina). Se generó una base de datos de incidencia del cáncer renal infantil con información del Registro Provincial de Tumores. Se realizaron análisis de conglomerados espaciotemporales. En localidades dentro de los conglomerados, se llevaron a cabo entrevistas en profundidad a informantes claves.

Resultados:

Se registraron 56 casos de tumores renales pediátricos en el Registro en el periodo 2004-2013. Se detectó un conglomerado espacial significativo que abarca siete departamentos de la provincia. En esa región se concretaron seis entrevistas en profundidad a informantes claves. Los entrevistados resaltaron la mayor frecuencia de enfermedad genética de Sandhoff y las prácticas de endogamia (corroboradas en numerosos resultados científicos). A partir de estos datos se determinaron zonas de superposición de tumores renales y de la enfermedad de Sandhoff.

Conclusiones:

Se detectó una región particular de la provincia con alta frecuencia de tumores renales pediátricos y de la enfermedad de Sandhoff. Numerosos estudios científicos determinan que la endogamia es el factor de riesgo que aumenta la frecuencia de esta enfermedad en esta región. En futuras investigaciones se deberá corroborar si la endogamia también actúa aumentando la incidencia de tumores renales infantiles(AU)
ABSTRACT

Introduction:

There is little research on risk factors of pediatric renal tumors.

Objective:

To characterize in detail the geographic regions of greatest incidence of pediatric renal tumors in central Argentina and exploring their possible link to genetic risk factors.

Methods:

The study area comprised the province of Córdoba (Argentina), and a database of pediatric renal tumors incidence was generated with information from the Provincial Tumor Registry. Analyses of spatio-temporal clusters were performed. In-depth interviews with key informants were carried out at localities within the conglomerates.

Results:

56 cases of pediatric renal tumors were registered in the Provincial Registry of Tumors between 2004 and 2013. A significant spatial conglomerate was detected, covering seven districts of the province. In that region, six in-depth interviews were conducted with key informants. Interviewees highlighted the increased frequency of Sandhoff genetic disease and endogamous practices (corroborated in numerous scientific results). From these data, zones of overlap of renal tumors and of Sandhoff disease were determined.

Conclusions:

A particular region of the province was detected with high frequency of pediatric renal tumors and Sandhoff disease. Numerous scientific studies have determined that endogamy is the risk factor that increases the frequency of Sandhoff disease in this region. In future research, it should be confirmed whether it also acts by increasing the incidence of renal tumors in children(AU)
