ABSTRACT
OBJETIVO: Relatar os efeitos endócrinos tardios em crianças e adolescentes após tratamento oncológico e associá-los à doença de base e ao tratamento. SUJEITOS E MÉTODOS: Foram realizadas avaliações clínicas e laboratoriais visando à detecção de distúrbios endócrinos em 320 pacientes após terapia oncológica, seguidos por seis anos. RESULTADOS: Em 94 pacientes, detectaram-se: 32 pacientes apresentaram baixa estatura (nove em tratamento com hormônio de crescimento), 14 tiveram puberdade precoce (10 em uso de análogo de GnRH) e 19 revelaram ser portadores de distúrbios de tireoide (12 com hipotireoidismo, seis com nódulos de tireoide e um com tireoidite linfocitária crônica). Obesidade foi encontrada em 18 deles. Seis com diabetes insípido e cinco com puberdade atrasada, três com pan-hipopituitarismo. Houve associação entre a radioterapia e a presença de endocrinopatias. CONCLUSÃO: Noventa e quatro de 320 (30 por cento) dos pacientes fora de terapia apresentaram alteração endócrina, o que enfatiza a importância do seguimento precoce e regular, possibilitando-lhes, com tratamento, melhor qualidade de vida.
OBJECTIVE: To report the main endocrine effects after cancer treatment in children and adolescents and associate them to the disease and its treatment. SUBJECTS AND METHODS: Clinical and lab evaluation for endocrinopathy was performed in 320 patients after cancer therapy have been followed for six years. RESULTS: The most prevalent endocrine late effects in patients were: 32 patients had short stature, nine of them were under growth hormone therapy. Precocious puberty was found in 14 patients, 10 of them received GnRH analog. Thyroid diseases were present in 19 patients (12 with hypothyroidism; six with thyroid nodules/cysts; one with chronic lymphocytic thyroidytis). Obesity was found in 18 patients. Six presented insipidus diabetes, five delayed puberty and three panhypopituitarism. Radiation was associated with the appearance of the aforementioned endocrinopathies. CONCLUSION: Ninety four of 320 (30 percent) patients presented endocrine late effects which emphasize the importance for these patients to be regularly followed-up in order to precociously diagnose endocrine late effects and provide them a better quality of life.
