El carcinoma papilar de tiroides es un tumor frecuente en mujeres y el número de casos nuevos viene en crecimiento. La mayoría de estos casos de novo son tumores menores de 2 centímetros. Parte de la responsabilidad de este aumento es explicable por un uso mayor de ayudas diagnósticas. Esto ha permitido detectar el cáncer de tiroides temprano o clínicamente silente. En esta población, el manejo ha sido típicamente agresivo, incluyendo cirugías extensas (tiroidectomía total) seguidas por terapia con yodo radiactivo y supresión de TSH. Las próximas guías plantearán cuatro grandes modificaciones: 1. Estadificación dinámica del riesgo (respuesta completa, respuesta bioquímica incompleta, respuesta estructural incompleta e indeterminada) 2. Disminución de las indicaciones y de la dosis de ablación con yodo radiactivo, específicamente el uso de esta terapia debe estar ajustado al riesgo basal de recurrencia (bajo, intermedio, alto) del paciente y debe tenerse en cuenta el número de ganglios linfáticos afectados, el tamaño de las metástasis ganglionares, la histología y el tamaño del tumor. Una dosis de 30 mCi de 131yodo es igual de eficaz para negativizar la tiroglobulina que una dosis de 100 mCi. 3. Extensión de la cirugía (cirugía parcial en tumores menores de 4 cm con histología favorable) y 4. Terapia de supresión con levotiroxina con metas más laxas de TSH, dado el riesgo de osteoporosis y arritmias con una supresión exagerada de TSH, especialmente en la población de edad avanzada.Abstract Papillary thyroid carcinoma is a frequent cancer in women. An increase in the number of new cases has been detected in the last years. However, tumors smaller than 2 cms represent the largest sample in those new detected cancers. The cause of this increment is partially responsibility of an increased use of diagnostic aids such as ultrasound, even in asymptomatic patients. The management of these clinically silent tumors has been quite aggressive with extensive surgery (total thyroidectomy) followed by radioactive iodine therapy and TSH suppression. The next papillary thyroid carcinoma guidelines will address 4 important modifications: 1. Dynamic approach to risk stratification (Complete response, incomplete biochemical response, incomplete structural response and indeterminate response) 2. Decrease in the indication and dose of radioactive iodine. The use of this therapy must be adjusted to the basal risk of recurrence with consideration of the number of lymph node metastases, the size of the lymph node metastases, the histopathologic variant and the size of the primary tumor. A dose of 30mCi of 131I is as effective as a dose of 100 mCi for thyroid ablation. 3. Extension of the thyroidectomy (partial surgery in tumors smaller than 4 cms without unfavorable histopathology and 4. Higher TSH goal with levothyroxine suppression therapy. A strict TSH suppression has been associated with increased risk of osteoporosis and cardiac arrhythmias, especially in older population.

Objectives. We compared the ultrasonography and pathology features of papillary thyroid carcinoma (PTC) in pediatric and adolescents with Hashimoto’s thyroiditis (HT) with those of non-HT patients.Materials and Methods. Eleven patients who were surgically confirmed to have pediatric or adolescent PTC from 2006 to 2014 were included in this study. We retrospectively analyzed the preoperative ultrasonography and pathology features of PTC arising in HT and non-HT patients.Results. On ultrasonography, thyroid gland was lobulated and enlarged, with many scattered microcalcifications in four of five HT patients. Four of six non-HT patients had suspicious masses with calcifications. The diffuse sclerosing variant of PTC (DSVPTC) was found in three of five HT patients, but none in non-HT patients. Macroscopic or microscopic extrathyroidal extension was evident in all of the HT patients and four of the non-HT patients. Neck lymph node metastases were in all HT patients and five of non-HT patients.Conclusions. Three of five PTCs in pediatric and adolescent HT patients were DSVPTC, whereas all PTCs of the non-HT patients were classic type. On ultrasonography, thyroid gland was diffusely enlarged with scattered microcalcifications in four of five HT patients. All five HT cases had aggressive disease, including extrathyroidal extension and cervical lymph node metastases.
