Resumen
Antecedentes: El diagnóstico de cáncer de ovario es importante que se realice de manera temprana ya que en esta etapa la supervivencia es alta, no así en el estadio avanzado. La US es la herramientas diagnóstica más importante para el estudio de la tumoración de ovario, Sin embargo, no siempre se cuenta con personal experimentado. Recientemente la propuesta IOTA-ADNEX busca dar una nueva herramienta para identificar tumoraciones con altas riesgo de malignidad. Objetivos: Determinar la utilidad de la herramienta IOTA-ADNEX para predecir malignidad en tumores de ovario Metodología: Se realizó un estudio transversal que incluyó de manea no aleatoria, 53 casos consecutivos de pacientes atendidas por el servicio de Ginecología por tumoración de ovario en los cuales se realizó estudio ecográfico por personal con experiencia y tenían diagnóstico histopatológico del espécimen quirúrgico y se realizó el cálculo con el IOTA / ADNEX. Se excluyeron pacientes con antecedentes de cáncer de ovario, embarazo, cirugía realizada más de 4 meses después de la ecografía. Resultado: La prevalencia de malignidad fue del 11%. Los parámetros con un punto de corte de IOTA / ADNEX de 30 fueron S 66.7%, E 72.3%, VPP; 23.5%, VPN 94.4%; el diagnóstico correcto con este corte fue del 71.7%. Con un punto de corte de 10 los valores fueron S 100%, E 44.7%, VPP 18.6% y VPN 100%; el diagnóstico correcto con este punto de corte fue de 50.94% Conclusiones: La herramienta IOTA-ADNEX no es una herramienta adecuada para predecir malignidad entre pacientes con tumores de ovario Palabras Claves: Tumor de ovario, Diagnóstico, Ecografía, Pronóstico
Background: It is important to diagnose ovarian cancer early, since survival is high at this stage, but not in the advanced stage. US is the most important diagnostic tool for the study of ovarian tumors. However, experienced personnel are not always available. Recently, the IOTA-ADNEX proposal seeks to provide a new tool to identify tumors with a high risk of malignancy. Objectives: To determine the usefulness of the IOTA-ADNEX tool to predict malignancy in ovarian tumors. Methodology: A cross-sectional study was carried out that included, in a non-random manner, 53 consecutive cases of patients attended by the Gynecology service for ovarian tumors in which An ultrasound study was performed by experienced personnel who had a histopathological diagnosis of the surgical specimen and the calculation was performed with IOTA / ADNEX. Patients with a history of ovarian cancer, pregnancy, surgery performed more than 4 months after ultrasound were excluded. Result: The prevalence of malignancy was 11%. Parameters with an IOTA / ADNEX cutoff of 30 were S 66.7%, E 72.3%, PPV; 23.5%, NPV 94.4%; the correct diagnosis with this section was 71.7%. With a cut-off point of 10, the values were S 100%, E 44.7%, PPV 18.6% and NPV 100%; the correct diagnosis with this cut-off point was 50.94%. Conclusions: The IOTA-ADNEX tool is not an adequate tool to predict malignancy among patients with ovarian tumors Keywords: Ovarian tumor, Diagnosis, Ultrasound, Prognosis
