Estimación de la Incidencia de Cáncer de Tiroides en Capital Federal y el Gran Buenos Aires (período 2003-2011)

Abstract

La incidencia del cáncer de tiroides ha aumentado significativamente en las últimas décadas en el resto del mundo. En Argentina no existe un registro nacional de cáncer por lo que la incidencia del mismo no puede establecerse. Por lo tanto, nuestro objetivo fue estimar la incidencia de cáncer de tiroides en la población de la Ciudad Autónoma de Buenos aires y Gran Buenos Aires así como la relación por género y la histología en el período de 2003 hasta 2011. Asumiendo que la población de afiliados a la Obra Social de la Policía Federal Argentina es representativa de los habitantes de Buenos Aires y el conurbano calculamos que la incidencia es de 6,51 casos/100.000 habitantes/año, con un incremento en 25 años mayor al doble, con predominio del carcinoma papilar frente al folicular.

Thyroid cancer incidence has significantly risen worldwide in the last decades. In Argentina, there is no national cancer registry; therefore its incidence can not be established. The objective of this study was to estimate the incidence of thyroid cancer in the population of Buenos Aires City and suburbs, and the relationship between gender and histology over the period 2003-2011. Assuming that the population affiliated to the Social Security of the Argentine Federal Police is representative of the inhabitants of Buenos Aires City and suburbs, we estimate an incidence of 6.51 cases/100,000 population/year, with an increasing incidence of almost double from 1981-1986 to 2003-2011. An increase in papillary thyroid cancer was mainly responsible for this rising trend. Incidence rates were higher for females (11.76/100,000 women) compared to those for males (2.65/100,000 men). Among men and women of all ages, the highest rate of incidence was for tumor size < 1 cm.Thyroid cancer incidence has significantly risen worldwide in the last decades.
