Resumen
Introducción

La asociación entre testosterona y cáncer prostático es mal comprendida. Los niveles de testosterona no son concluyentes para distinguir procesos prostáticos benignos de malignos. El objetivo de nuestro trabajo es determinar la relación existente entre niveles de testosterona en suero y cáncer prostático.

Material y método

Se estudiaron en forma prospectiva 38 pacientes portadores de cáncer prostático y un grupo control de 32, con edades que fluctuaron entre los 50 y 80 años. La testosterona total y libre fue determinada por radioinmunoensayo. El análisis estadístico realizado fue descriptivo inferencial, con bandas de confianza de 95%.

Resultados

Los valores promedio de testosterona total y libre, fueron significativamente menores en los pacientes portadores de cáncer. No se demostró ninguna correlación entre gleason, antígeno prostático y etapa tumoral con testosterona sérica.

Conclusiones

Nuestro trabajo demostró que la testosterona es significativamente menor en los pacientes con cáncer prostático en relación a los controles.
