ABSTRACT
El cáncer papilar de tiroides es el tumor tiroideo más común en la infancia. En estadios avanzados, puede presentarse con cuadro de insuficiencia respiratoria. El tratamiento de elección es la tiroidectomía total y iodo radiactivo. En tumores irresecables, se debería considerar terapia con inhibidores multicinasa.Niña de 10 años de edad derivada por insuficiencia respiratoria progresiva. Se realizó el diagnóstico de cáncer papilar de tiroides con metástasis pulmonares. Por presentar un tumor irresecable no pasible de cirugía, se indicó el uso compasivo de lenvatinib, que mostró una rápida y favorable respuesta clínica con resolución de la insuficiencia respiratoria al noveno día del tratamiento.El diagnóstico temprano de cáncer papilar de tiroides previene la grave morbilidad respiratoria ocasionada por diagnósticos tardíos. Podría considerarse el uso de lenvatinib como alternativa previa a las terapias de primera línea (cirugía e iodo radiactivo) en casos de enfermedad con gran compromiso local y a distancia.
Papillary thyroid cancer is the most common thyroid tumor in childhood. In advanced stages, it can present with respiratory failure. The treatment of choice is total thyroidectomy and radioactive iodine. In cases of unresectable tumors, therapy with multikinase inhibitors should be considered. A 10-year-old girl was referred for progressive respiratory failure. A diagnosis of papillary thyroid cancer with pulmonary metastases was made. Due to the presence of an unresectable tumor not subject to surgery, the compassionate use of lenvatinib was indicated, showing a rapid and favorable clinical response with resolution of respiratory failure on the ninth day.Early diagnosis of papillary thyroid cancer prevents severe respiratory morbidity caused by late diagnoses. The use of lenvatinib should be considered as a previous step towards first-line therapies (surgery and radioactive iodine) in cases with great local and distant involvement.

Objetivo: Avaliar o perfil epidemiológico de pacientes com diagnóstico de carcinoma diferenciado de tireoide. Métodos: Estudo analítico descritivo, realizado por meio da análise e da coleta de dados de 34 prontuários de pacientes em seguimento em um ambulatório de endocrinologia de um hospital público em São Paulo. Foram incluídos todos os pacientes em acompanhamento no ambulatório com diagnóstico de tumores diferenciados; foram excluídos os menores de 18 anos e/ou com diagnóstico de outras neoplasias de tireoide (que não tumores diferenciados). Resultados: A idade dos pacientes variou de 25 a 84 anos ao diagnóstico, com média de 51 anos, tendo sido representados por 32 mulheres (94,11%) e 2 homens (5,88%). A maioria dos tumores (41,17%) possuía tamanho entre 1 e 2cm. A maior parte dos pacientes tinha baixo risco de recorrência, e todos foram tratados cirurgicamente. Conclusão: O tumor diferenciado mais frequente é o subtipo papilífero. Sua prevalência se dá em mulheres, com média de idade ao diagnóstico de 51 anos. (AU)
Objective: To evaluate the epidemiological profile of patients with differentiated thyroid carcinoma. Methods: Th is i s a d escriptive, analytical study performed through the analysis and collection of data from 34 medical records of patients being followed in an endocrinology clinic of a public hospital in the city of São Paulo. All patients being followed at the outpatients' department with a diagnosis of differentiated thyroid carcinoma were included, and those under 18 and/or with diagnosis of other cancer of the thyroid (other than differentiated tumors) were excluded. Results: the patients' ages ranged from 25 to 84 years at diagnosis, an average of 51 years represented by 32 women (94.11%) and 2 men (5.88%). Most tumors (41.17 %) were between 1 and 2cm. Most patients showed low risk of recurrence, and all were surgically treated. Conclusion: The most frequent differentiated tumor was the papillary one. Its prevalence was on women, with an average age at diagnosis of 51 years. There were only two patients with recurrent disease, and one with metastasis to the lung that died. (AU)

Abstract: We report a 72-years-old male patient with extensive differentiated thyroid cancer (DTC), who required a tracheostomy and gastrostomy. Considering his clinical condition, risk of aspiration and management of the ostomies, radioiodine (131I) was administered intravenously, using recombinant human thyrotropin (rhTSH) and levothyroxine. The procedure was successful, both clinically and in terms of radioprotection.
