Abstract
Las adaptaciones metabólicas son un rasgo distintivo del cáncer y pueden aprovecharse para desarrollar nuevas herramientas diagnósticas y terapéuticas. Sólo alrededor del 50% de los pacientes sometidos a tiroidectomía por sospecha de cáncer de tiroides padecen realmente la enfermedad tras el análisis anatomopatológico, lo que pone de manifiesto las limitaciones diagnósticas de las herramientas actuales de las que disponemos. Objetivos: Investigar biomarcadores sanguíneos basados en el análisis del ADN mitocondrial que permitan evaluar de manera no invasiva y precisa los pacientes con cáncer de tiroides y proporcionar una medida cuantitativa fiable del riesgo metabólico de cada paciente y su posible aplicabilidad en el desarrollo de la cirugía del cáncer diferenciado de tiroides. Identificar variantes del ADN mitocondrial cuantificables en plasma que sirvan para medir el grado de disfunción metabólica a nivel tumoral y sistémico en el cáncer diferenciado de tiroides. Validar la capacidad predictiva del riesgo de desarrollo tumoral delos biomarcadores metabólicos identificados y su aplicabilidad en posibles cambios conductuales en la cirugía del cáncer diferenciado de tiroides...
Metabolic adaptations are a hallmark of cancer and may be exploited to develop novel diagnostic and therapeutic tools. Only about 50% of the patients who undergo thyroidectomy due to suspicion of thyroid cancer actually have the disease, highlighting the diagnostic limitations of current tools. Objectives: To investigate blood biomarkers based on mitochondrial DNA analysis that allow non-invasive and accurate assessment of thyroid cancer patients and provide a reliable quantitative measure of each patient's metabolic risk and its potential applicability in the development of surgery for differentiated thyroid cancer. To identify plasma quantifiable mitochondrial DNA variants that can be used to measure the degree of metabolic dysfunction at the tumor and systemic level in differentiated thyroid cancer. To validate the predictive capacity of the identified metabolic biomarkers for the risk of tumor development and their applicability in possible behavioral changes in surgery for differentiated thyroid cancer...
