title: Thyroid tumors in children and adolescents: preoperative study.
abstract: Several studies indicate that in young patients (less than 21 years of age at the time of diagnosis), the prognosis of thyroid carcinoma (TC) is more favorable than in older patients. However, a more radical treatment approach is recommended in children and adolescents due to the higher prevalence of local lymph-node involvement in these cases. Since the extent of primary surgical treatment is closely related to the overall prognosis, preoperative diagnosis becomes essential in the management of thyroid neoplasms in young patients. In this retrospective study (1987-1998), we analyzed a surgical series of 50 children and adolescents with thyroid nodules in an attempt to establish the role of diagnostic studies in detecting malignant lesions prior to surgery. Our diagnostic protocol for evaluating thyroid nodules was based on clinical evaluation, measurement of thyroid-hormone and thyroglobulin (TG) levels, anti-TG and anti-TPO antibody titers, calcitonin, CEA, and TPA levels, sonography, scintigraphy, and fine-needle aspiration cytology (FNAC) of the thyroid nodules and any enlarged lymph nodes. Eleven of the 15 cases of histologically confirmed carcinoma were preoperatively identified as malignant lesions with the aid of FNAC. The authors conclude that the preoperative work-up of children and adolescents with thyroid nodules requires the collaboration of an experienced team of professionals, and recommend FNAC as the initial test.
