Evolutionary analysis of indeterminate cytology and risk of malignancy in a thyroid nodule unit.

OBJECTIVE: The objective of this study was to analyze the evolution in the diagnosis and management of indeterminate thyroid nodules over three time periods. METHODS: 3020 patients with thyroid nodules underwent cytological evaluation during three periods (2006-2008, 2012-2014, 2017-2019). Distribution of diagnostic cytologies, risk of malignancy, diagnostic performance indices of FNA, and cytologic-histologic correlation in indeterminate cytologies were analyzed. RESULTS: only 2.2% of cytology tests were insufficient for a diagnosis. 86.9% cytologies were benign, 1.7% malignant, and 11.4% indeterminate. Indeterminate cytology rates were 15.9% (2006-2008), 10.1% (2012-2014), and 10% (2017-2019). Surgery was performed in 13% of benign cytology, result-ing in malignant histology in 2.7%. All malignant and suspicious cytologies underwent surgery: malig-nancy confirmed in 98% and 77% of cases, respectively. All 'indeterminate with atypia' cytologies (2006-2008) and Bethesda IV (2012-2014; 2017-2019) un-derwent surgery, with malignancy confirmed in 19.6%, 43.8%, and 25.7%, respectively. In the 'inde-terminate without atypia' category (2006-2008) and Bethesda III (2012-2014; 2017-2019), diagnostic surgery was performed in 57.7%, 78.6%, and 59.4%, respectively, with malignancy confirmed in 3.3%, 20.5%, and 31.6%. The FNA sensitivity was 91.6% with a negative predictive value greater than 96% in all periods. The specificity exceeded 75% in the last two periods. CONCLUSION: Bethesda system reduces indeterminate cytologies and improves the accuracy of FNA diagnosis. We reported a higher proportion of malignancy than expected in Bethesda III, underscoring the importance of having institution-specific data to guide decision-making. However, there is a need for risk stratification tools that allow for conservative management in low-risk cases.

Efficacy of Low-Dose Radioiodine Ablation in Low- and Intermediate-Risk Differentiated Thyroid Cancer: A Retrospective Comparative Analysis.

(1) Background-low-dose radioiodine ablation is an accepted strategy for the treatment of low- and intermediate-risk thyroid carcinomas, although there is no international consensus. The aim of this study is to describe the clinical experience with low-dose radioiodine ablation in patients with low- and intermediate-risk thyroid cancer compared to high-dose ablation. (2) Methods-174 patients with low- and intermediate-risk thyroid cancer, 90 treated with low-dose ablation and 84 treated with high-dose ablation, were included. The primary endpoint was response to treatment one year after ablation, defined by stimulated thyroglobulin, whole body scan and ultrasound imaging. (3) Results-an excellent response rate of 79.8% in the low-dose group and 85.7% in the high-dose group was observed (p = 0.049). Stimulated thyroglobulin at the moment of ablation (p = 0.032) and positive antithyroglobulin antibodies (p < 0.001) were independent predictive factors for nonexcellent response. Young age (p = 0.023), intermediate initial recurrence risk (p < 0.001) and low-dose ablation (p = 0.004) were independent predictive factors for recurrence. (4) Conclusion-low-dose ablation seemed to be less effective than high-dose ablation, especially in those patients with positive antithyroglobulin antibodies or higher stimulated thyroglobulin levels at the moment of ablation. Low dose was associated with higher recurrence rates, and lower age and intermediate initial recurrence risk were independent risk factors for recurrence in our sample.

New molecular biomarkers in differentiated thyroid carcinoma: Impact of miR-146, miR-221 and miR-222 levels in the evolution of the disease.

OBJECTIVE: MircroRNAs (miR) are small, noncoding RNA molecules of 18-25 nucleotides. Their dysregulation has been widely studied in many human tumours including differentiated thyroid cancer (DTC). miRs more frequently associated with these kinds of tumours are miR-146, miR-221 and miR-222. Our objective was to assess the relationship among circulating miR levels and the evolution and outcomes of disease. DESIGN: We analysed a sample of 60 patients with DTC assigning them to one of three groups according to the dynamic scale of risk (excellent response, incomplete biochemical response and incomplete structural response). PATIENTS AND MEASUREMENTS: At study inclusion, we determined thyroid-stimulating hormone, thyroxine, thyroglobulin, antithyroglobulin antibodies and plasma levels of miR-146, miR-221 and miR-222. RESULTS: Male sex and advanced age at diagnosis were associated with the worst disease progression. miR-222 was twofold to threefold higher in tall cell papillary carcinomas (P = 0.038). miR-146 (P = 0.016) and miR-221 (P = 0.050) had a positive correlation with thyroglobulin at the time of sampling. In regression analysis, miR-146 (P = 0.006), miR-221 (P = 0.004) and miR-222 (P = 0.007) predicted more than 70% of the variation in thyroglobulin levels at the time of sampling. CONCLUSIONS: Elevated miR-222 and miR-146 levels are associated with poorer outcomes of the disease and may have a prognostic value in the management and follow-up of DTC.

OBJETIVO: Evaluar la tolerancia a lixisenatida y sus efectos sobre el peso y el control metabólico de pacientes con diabetes tipo 2 y obesidad. DISEÑO: Estudio prospectivo. Emplazamiento: Consultas de atención especializada de Endocrinología y Nutrición en Almería, Granada y Málaga. PARTICIPANTES: Pacientes con diabetes tipo 2 y obesidad. INTERVENCIONES: Respuesta y tolerancia al tratamiento con lixisenatida. Mediciones principales: Se analizaron datos clínicos y analíticos con medidas de cambio intrasujeto antes-después del tratamiento. RESULTADOS: Evaluamos 104 pacientes (51% mujeres) con diabetes tipo 2 y obesidad (Almería 18,3%; Granada 40,4%; Málaga 41,3%). Edad media 58,4±10,5 años y duración media de diabetes 11,2±6,7 años. El tiempo medio desde la visita basal a la revisión tras inicio de tratamiento con lixisenatida fue de 3,8±1,6 meses. Encontramos mejoría significativa del peso (p < 0,001), índice de masa corporal (p < 0,001), circunferencia de cintura (p = 0,002), presión arterial sistólica (p < 0,001) y diastólica (p = 0,001), glucemia en ayunas (p < 0,001), HbA1c (p = 0,022), colesterol total (p < 0,001), colesterol LDL (p = 0,046) y triglicéridos (p = 0,020). No se observó alteración de cifras de amilasa en relación con el tratamiento con lixisenatida, y el 7,9% no lo toleraron. CONCLUSIONES: Lixisenatida consigue: 1) mejoría significativa de parámetros antropométricos y control glucémico (glucemia basal y HbA1c); 2) descenso significativo de la presión arterial y del perfil lipídico, y 3) seguridad y buena tolerancia en la mayoría de los pacientes. Además, encontramos una significativa intensificación del tratamiento antihipertensivo e hipolipemiante

Fundamentos y objetivos El hallazgo de un nódulo tiroideo es un hecho muy frecuente en la práctica clínica habitual. El manejo del nódulo tiroideo necesita un abordaje multidisciplinar que puede ser facilitado con la creación de unidades de alta resolución de nódulo tiroideo. Describimos la experiencia clínica y los resultados obtenidos en una consulta de alta resolución y acto único de nódulo tiroideo. Material y métodos Se han evaluado todos los pacientes derivados a la consulta de nódulo tiroideo del Hospital Virgen de la Victoria (Málaga) desde el año 2005 al 2007. Se han seguido las guías de práctica clínica de nódulo tiroideo para la recomendación de punción aspirativa con aguja fina (PAAF) y cirugía tiroidea. Se realizó análisis estadístico con programa SPSS. Resultados Durante el periodo de estudio, la consulta de nódulo tiroideo atendió a 658 pacientes (edad media 48,6 años, 89,8% mujeres). Mediante ecografía se confirmó la existencia de nódulo tiroideo en el 85,5% de los pacientes. Con un diámetro medio de 1,96cm, un 74,2% de nódulos fueron sólidos, un 55,8% hipoecoicos, y un 4,7% presentaron microcalcificaciones. Se realizó la PAAF a 475 pacientes. El 76,5% de las citologías fueron benignas, el 19,1% sospechosas, el 2,1% malignas y el 2,3% insuficientes. Se derivó a cirugía al 23,3% de los pacientes (principalmente por tamaño nodular o sospecha de malignidad). Se confirmó la existencia de patología maligna (principalmente carcinoma papilar) en el 24,9% de los nódulos intervenidos. La sensibilidad/especificidad de la citología (considerando la biopsia como el gold standard) fue del 81,8 y el 94,7%, respectivamente. Conclusiones La instauración de una consulta monográfica de nódulo tiroideo permite la optimización de recursos y reduce la demora diagnóstica, obteniendo unos resultados clínicos ampliamente satisfactorios (AU)
