Embora tenha um bom prognóstico, 14% dos pacientes considerados como de baixo risco de recorrência podem apresentar doença persistente mesmo com tratamento adequado. Por isso, estudos têm sido realizados no intuito de encontrar outros possíveis preditores de persistência do CDT. OBJETIVO: Avaliar que fatores clínicos, laboratoriais e anatomopatológicos estão associados à persistência do CDT um ano após radioiodoterapia (RIT). METODOLOGIA: Foi realizada uma revisão de prontuários, na qual foram incluídos 375 pacientes portadores de CDT. Foram coletados dos registros os dados clínicos (gênero e idade), resultados de dosagens de hormônio tireoestimulante (TSH), tireoglobulina (Tg) e anticorpo anti-tireoglobulina (AATg) antes e um ano após RIT, resultados de varredura de corpo inteiro (PCI) após dose ablativa de radioiodo (131I) e um ano após tratamento inicial, além de laudos dos exames histopatológicos. A partir dos dados obtidos, foi realizada análise bivariada e as variáveis que apresentaram significância inferior a 20,0% (p < 0,20) foram submetidas à análise multivariada através do modelo de regressão de Poisson. Para se chegar a um valor de Tg estimulada (TgE) capaz de predizer os pacientes que teriam maior chance de persistência de doença, foi realizada uma curva ROC. RESULTADOS: Observou-se associação significativa entre persistência de doença e idade inferior a 45 anos (p=0,001), multifocalidade (p=0.008) e tamanho tumoral entre 2 a 4 cm (p=0,002). Além disso, verificou-se associação significativa entre da TgE e persistência do CDT (p<0,001). O ponto de corte de TgE pré-dose com maior sensibilidade e especificidade para prever persistência de doença foi de 7,4 ng/mL. Utilizando este valor encontramos um valor preditivo negativo (VPN) de 87,5%. CONCLUSÃO: Neste estudo encontramos uma forte associação entre persistência do CDT e faixa etária, tamanho tumoral, multifocalidade e Tg estimulada pré-ablação. A Tg estimulada pré-ablação mostrou-se um valioso preditor de persistência de CDT um ano após RIT. Valores de 7,4 ng/mL ou mais mostraram maior sensibilidade e especificidade para prever este desfecho. / BACKGROUND: Differentiated thyroid carcinoma (CDT) is evaluated and treated according to prognostic factors. Although it has a good prognosis, 14% of the patients which are considered at low risk of recurrence, might have persistent disease despite suitable treatment. Hence, studies have been realized in order to find other possible prognostic predictors for CDT persistence. OBJECTIVE: Assess which clinical, laboratory and pathological factors are associated with persistence of CDT one year after radioiodine therapy (RIT). METHODS: It was performed a chart review, in which was included 375 patients with CDT. Were collected clinical data (age and sex), results of thyroid-stimulating hormone (TSH), thyroglobulin (Tg) and antithyroglobulin antibody (AATg) before and one year after RIT, whole body scan (PCI) results after ablative dose of 131I and one year later and, also histopathological exam reports. From these data, was performed a bivariate analysis and the variables that were significant lower than 20.0% (p <0.20) were submitted to multivariate analysis using Poisson regression model. To achieve a stimulated Tg (TgE) value able to predict which patients would have a greater chance of persistent disease, a ROC curve was performed. RESULTS: A significant association was found between persistence of disease and age less than 45 years (p = 0.001), multifocality (p = 0.008) and tumor size between 2-4 cm (p = 0.002). In addition, there was a significant association between TgE and persistence of CDT (p <0.001). The pre-ablation TgE cutoff with greater sensitivity and specificity in predicting persistence of disease was 7.4 ng / mL. Using this value, we found a negative predictive value (VPN) of 87.5%. CONCLUSION: We found a significant association between persistent CDT and age, tumor size, multifocality and pre-ablation TgE in this study. TgE pre-ablation was shown to be a valuable predictor of persistence CDT one year after RIT. Values of 7.4 ng / ml or more showed greater sensitivity and specificity to predict this outcome.
