El uso de suplementos de tiroides en relación con el riesgo de cáncer de mama
JAMA
|October 10, 1980
Resumen
Este estudio no encontró ninguna relación entre el uso de suplementos de tiroides y el aumento del riesgo de cáncer de mama. Los investigadores compararon a mujeres con y sin cáncer de mama, encontrando tasas similares de uso de suplementos en ambos grupos.
Área de la Ciencia:
- Endocrinología Endocrinología.
- Oncología Oncología.
- Epidemiología La epidemiología.
Sus antecedentes:
- La hormona tiroidea juega un papel crucial en el metabolismo celular.
- La influencia potencial de la terapia de reemplazo de la hormona tiroidea en el riesgo de cáncer es un área de investigación en curso.
- Comprender los factores de riesgo para el cáncer de mama es vital para la salud pública.
Objetivo del estudio:
- Para investigar la asociación entre el uso de suplementos de tiroides y la incidencia de cáncer de mama.
- Para determinar si el uso a largo plazo de suplementos de tiroides eleva el riesgo de cáncer de mama.
Principales métodos:
- Se empleó un diseño de estudio de casos y controles.
- Se compararon 659 mujeres diagnosticadas con cáncer de mama con 1.719 sujetos de control.
- Se evaluaron las tasas de uso de suplementos de tiroides y se compararon entre los casos y los controles.
Principales resultados:
- La proporción de tasa estandarizada por edad para el uso de suplementos de tiroides fue de 1,0 (95% IC, 0,7 a 1,3), lo que indica que no hay diferencia significativa.
- No se observó un aumento en el riesgo de cáncer de mama, ni siquiera en los grupos de alto riesgo o con el uso prolongado (>15 años).
Conclusiones:
- La evidencia actual no apoya un vínculo entre el uso de suplementos de tiroides y un mayor riesgo de cáncer de mama.
- El uso a largo plazo de suplementos para la tiroides no parece ser un factor de riesgo para desarrollar cáncer de mama.

Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

Functions of Thyroid Hormones
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
