Resumen
Introducción: Las Hormonas Tiroideas (HT) son esenciales para el desarrollo,maduración y metabolismo de todos los tejidos del organismo,por lo que se ha postulado que podrían estar relacionadas también conel crecimiento tumoral. En estudios preclínicos, niveles alterados de HTse han relacionado con un mayor riesgo de desarrollar distintos tipos decáncer; entre ellos, el Cáncer de Próstata (CaP).Objetivo: Analizar artículos epidemiológicos, en donde se estudie la relacióndel hipertiroidismo y el CaP, publicados hasta el momento.Material y Método: Se buscó en plataformas de bases de datos, comoScopus, Mendeley, Science Direct y PubMed. Se filtró por los términoshipertiroidismo y cáncer de próstata, hormonas tiroideas y cáncer depróstata, y hormonas tiroideas y cáncer. Luego, fueron seleccionadosúnicamente los trabajos en humanos.Resultados: Se encontraron 5 estudios epidemiológicos que analizan larelación entre las HT y el CaP; 2 de ellos fueron trabajos retrospectivos,y el resto, prospectivos. Los estudios retrospectivos mostraron nivelesmás elevados de triyodotironina sérica (T3) en pacientes con hiperplasiaprostática benigna y en aquellos con mayor riesgo de recurrencia de CaP,comparados con los controles. Los estudios prospectivos demostraronuna relación inversa entre los niveles de TSH (hormona estimulante de latiroides) y el riesgo de desarrollar CaP, y una correlación positiva entre latiroxina (T4) y el riesgo de CaP.Conclusión: Se ha evidenciado un aumento del riesgo de CaP en personashipertiroideas o con hipertiroidismo iatrogénico resultado de tratamientoscon dosis inadecuadas de levotiroxina.
Introduction: Thyroid hormones are essential for the development, maturation and metabolism of all human tissues; therefore, it has been postulated that they could also be associated with tumor growth. Preclinical studies have found a relationship between altered levels of thyroid hormones with increased risk of developing different types of cancer, including prostate cancer. Objective: To analyze epidemiological articles where the relationship of hyperthyroidism and PCa is studied. Material and Method: we searched in database platforms including Scopus, Mendeley, Science Direct and PUBMED. We used key terms like hyperthyroidism and prostate cancer; thyroid hormones and prostate cancer; thyroid hormones and cancer. Then, we selected only those studies that were performed in humans. Results: we found 5 epidemiological studies that investigated the relationship between thyroid hormones and prostate cancer, 2 of them were retrospective and the rest prospective. In the retrospective studies, the authors found higher levels of serum triiodothyronine (T3) in patients with benign prostatic hyperplasia and in those with higher risk of prostate cancer recurrence. In the prospective studies, they observed an inverse relationship between TSH (Thyroid-Stimulating Hormone) circulating levels and the risk of prostate cancer, and a positive relationship between tiroxine (T4) serum levels and prostate cancer. Conclusion: it has been demonstrated an increased risk of prostate cancer in hyperthyroid participants or with iatrogenic hyperthyroidism due to treatment with inadequate doses of levothyroxine.
