Abstract: | Objective: To analyze the association of clinical, anatomical, and ultrasound (US) characteristics of malignancies in Bethesda III or IV (III-B or IV-B) thyroid nodules. Subjects and methods: The association between malignancies and the following variables were analyzed: III-B or IV-B, age < 55 years and ≥ 55 years, sex, family history of thyroid cancer, history of irradiation, nodule size, and ACR TI-RADS classification in 62 participants who underwent thyroidectomy. Results: Of the 62 participants, 87.1% (54/62) were women, 74.2% were < 55 years old, 95.2% had no family history of thyroid cancer, 56.5% had nodules < 2 cm in size, 62.9% were IV-B, and 69.4% were ACR TI-RADS 4. Thirty-two patients had thyroid carcinoma, and 30 had benign histology. Among all factors associated with malignancy, only ACR TI-RADS 5 classification on US was found to be statistically significant (p = 0.014), while III-B with architectural atypia cytological classification was the only one significantly associated with benign status (p = 0.004). Conclusion: Only a high risk of malignancy as assessed using US was able to refine the indication for molecular tests in a group of patients with indeterminate nodules. We found 85% (53/62) of III-B or IV-B thyroid nodules would benefit from available molecular diagnostic tests. |
Abstract: | Objetivo: Analisar a associação das características clínicas, anatômicas e ultrassonográficas (US) das neoplasias em nódulos tireoidianos Bethesda III ou IV (III-B ou IV-B). Sujeitos e métodos: Foi analisada a associação entre malignidades e as seguintes variáveis: III-B ou IV-B, idade < 55 anos e ≥ 55 anos, sexo, história familiar de câncer de tireoide, história de irradiação, tamanho do nódulo e ACR TI -Classificação RADS em 62 participantes submetidos à tireoidectomia. Resultados: Dos 62 participantes, 87,1% (54/62) eram mulheres, 74,2% tinham < 55 anos, 95,2% não tinham histórico familiar de câncer de tireoide, 56,5% tinham nódulos < 2 cm de tamanho, 62,9% eram IV- B, e 69,4% eram ACR TI-RADS 4. Trinta e dois pacientes tinham carcinoma de tireoide e 30 tinham histologia benigna. Entre todos os fatores associados à malignidade, apenas a classificação ACR TI-RADS 5 na US foi estatisticamente significativa (p = 0,014), enquanto a classificação citológica III-B com atipia arquitetônica foi a única significativamente associada ao estado benigno (p = 0,004 ). Conclusão: Somente o alto risco de malignidade avaliado pela US foi capaz de refinar a indicação de testes moleculares em um grupo de pacientes com nódulos indeterminados. Descobrimos que 85% (53/62) dos nódulos tireoidianos III-B ou IV-B se beneficiariam com os testes de diagnóstico molecular disponíveis. |
