Abstract (English): Thyroid cancer (TC) is the first malignant tumor in endocrine glands, and it is estimated that by 2030 it will be in the top five cancers worldwide. In Chile, TC was recently included as pathology No. 82 with Explicit Health Guarantees, which implies allocating significant public and private resources to the treatment of patients with a cancer that is on the rise. There are groups of young patients with small tumors that present a more aggressive clinical behavior, where decision-making could be advanced. Specifically, a group of patients under 55 years of age with tumors less than 2 cm in size but with regional metastases, that lack indication for radioiodine therapy and could require complementary treatment or present a worse evolution. Clinical and molecular tools to guide appropriate treatment in patients with lymph node metastases are limited and have not been updated. There are tumorigenicity and prognostic factors, such as EpithelialMesenchymal Transition (EMT) and Cancer Stem Cells (CSC) markers that have been incorporated into the study of other tumors and recently in thyroid cancer. Studies linking EMT and CSC with TC currently point to molecular and genetic description, with few reports clinically correlating these findings (particularly in subgroups with particular characteristics of aggressiveness) and proposing them as tumorigenicity and prognosis markers. The description of these biomarkers in the described population could facilitate decision-making regarding follow-up, surgical therapy, and radioiodine therapy. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): El cáncer de tiroides (CT) es el primer tumor maligno en glándulas endocrinas, y se estima que al 2030 estará en el top cinco de cáncer a nivel mundial. En Chile, el CT fue incluido, recientemente, como la patología N° 82 con Garantías Explícitas de Salud, lo que implica destinar importantes recursos públicos y privados al tratamiento de pacientes con un cáncer que va en aumento en el mundo. Existen grupos de pacientes jóvenes con tumores pequeños que presentan un comportamiento clínico más agresivo desde el inicio, donde se podría adelantar la toma de decisiones. Específicamente, destaca un grupo de pacientes menores de 55 años con tumores pequeños menores de 2 cm, pero con metástasis regionales, que quedan fuera de la indicación de radioyodoterapia y podrían requerir tratamiento complementario o presentar peor evolución. Las herramientas clínicas y moleculares para guiar el tratamiento adecuado en pacientes con metástasis linfonodales son limitadas y no han sido actualizadas hasta el momento. Existen factores de tumorigenicidad y pronóstico, tales como los marcadores de Transición Epitelio-Mesenquimal (TEM) y Cáncer Stem Cells (CSC) que se han incorporado al estudio de otros tumores y recientemente en cáncer de tiroides. Actualmente estudios que relacionan TEM y CSC con CT apuntan a la descripción molecular y genética, con escasos reportes que correlacionen, clínicamente, estos hallazgos, (particularmente en subgrupos con características particulares de agresividad) y que los propongan como marcadores de tumorigenicidad y pronóstico. La descripción de estos biomarcadores en la población descrita podría facilitar la toma de decisiones en cuanto a seguimiento, terapia quirúrgica y radioyodoterapia. [ABSTRACT FROM AUTHOR]
