ABSTRACT
OBJECTIVE: To evaluate the usefulness of preoperative serum calcitonin (sCT) in patients with nodular disease without suspicion of medullary thyroid carcinoma (MTC) in history or cytology. PATIENTS AND METHODS: sCT was measured before thyroidectomy in 494 patients with nodular disease who had no family history of MTC or multiple endocrine neoplasia type 2, and no cytological suspicion of MTC. RESULTS: Basal sCT was < 10 ng/mL in 482 patients and none of them had MTC. One patient with basal sCT > 100 pg/mL had MTC. Among the 11 patients with basal sCT between 10 and 100 pg/mL, MTC was diagnosed in only one. The two patients with MTC were submitted to total thyroidectomy, combined with elective lymph node dissection indicated exclusively based on hypercalcitoninemia, and sCT was undetectable after six months. CONCLUSIONS: Preoperative sCT is useful for the detection of sporadic MTC in patients with nodular disease, even in the absence of suspicious history or cytology.
RESUMO
OBJETIVO: Avaliar a utilidade da calcitonina sérica (sCT) pré-operatória em pacientes com doença nodular sem suspeita de carcinoma medular de tireoide (CMT) pela história e citologia. PACIENTES E MÉTODOS: Antes da tireoidectomia, sCT foi dosada em 494 pacientes com doença nodular, sem história familiar de CMT ou neoplasia endócrina múltipla tipo 2 e sem citologia suspeita para CMT. RESULTADOS: sCT basal foi < 10 ng/ml em 482 pacientes e nenhum possuía CMT. Um paciente com sCT basal > 100 pg/ml realmente possuía CMT. Dos 11 pacientes com sCT basal entre 10 e 100 pg/ml, CMT foi diagnosticado em apenas um. Os dois pacientes com CMT foram submetidos à tireoidectomia total com dissecção eletiva de linfonodos, indicada exclusivamente pela hipercalcitoninemia, e após seis meses apresentaram sCT indetectável. CONCLUSÕES: Em pacientes com doença nodular, mesmo sem história ou citologia suspeitas, a sCT pré-operatória é útil para detecção do CMT esporádico.
