Objetivos

Evaluar el impacto sobre la función gonadal del trasplante de médula ósea realizado durante la infancia.

métodos

Estudiamos la función gonadal en 19 pacientes pospuberales (13 varones y 6 mujeres) de 12,6 a 20 años de edad, 2 a 9 años después de haber sido sometidos a trasplante de médula ósea por distintas enfermedades. Quince pacientes habían recibido tratamiento quimioterápico previo y 6 pacientes radioterapia craneal; 11 pacientes recibieron radioterapia corporal total durante el acondicionamiento. Se caracterizaron los estadios de Tanner de desarrollo puberal y se midieron el volumen testicular en los varones (orquidómetro de Prader) y las concentraciones séricas de LH, FSH, testosterona y 17-beta-estradiol.

Resultados

Doce pacientes presentaron disfunción gonadal primaria. Tres de ellos no habían recibido radioterapia corporal total.

Conclusiones

Los resultados obtenidos demuestran que la disfunción gonadal es una secuela frecuente en los niños sometidos a trasplante de médula ósea; el daño puede ser atribuido tanto a la quimioterapia como a la radioterapia, sin poder excluir un efecto sinérgico de ambas. El hecho de que el trasplante tuviera lugar en la etapa prepuberal no puede considerarse en nuestra serie como un factor protector frente al daño gonadal inducido por quimioterapia o radioterapia.

Objective

To evaluate the effect of bone marrow transplantation during childhood on gonadal function in postpubertal patients.

Procedure

We studied 19 post-pubertal patients (13 males, 6 females) aged 13-20 years, 2-9 years after bone marrow transplantation for diverse diseases. Fifteen patients had received multi-agent cytotoxic treatment and 6 had received cranial irradiation prior to transplantation; eleven patients received total body irradiation. Gonadal function was assessed by typifying Tanner's stages of pubertal development and by measuring testicular volume in males (Prader's orchidometer). Serum concentrations of lutei-nizing hormone, follicle-stimulating hormone, testosterone and 17-beta-estradiol were also measured.

Results

Twelve patients were found to have gonadal dysfunction of gonadal origin. Of these, three had not received total body irradiation.

Conclusions

The results obtained show that gonadal dysfunction is frequent in patients treated with bone marrow transplantation. This damage can be attributed to both chemo-and radiotherapy but a synergistic effect between these treatments could not be excluded. The prepubertal status of patients at the moment of transplantation was not a protective factor against chemo- or radiotherapy-induced gonadal damage in our series.
