Abstract
La caquexia es un trastorno metabólico multifactorial caracterizado por la pérdida involuntaria de peso, principalmente a expensas de tejido muscular y adiposo, que afecta a de forma global más de la mitad de los pacientes con cáncer. La inflamación a nivel sistémico, la liberación de sustancias por parte del tumor y otros factores neuroendocrinos contribuyen a la creación de un estado metabólico caracterizado por un elevado gasto energético, donde predominan procesos catabólicos como proteólisis y lipólisis con un claro reflejo clínico. En la actualidad no se dispone de biomarcadores que permitan un diagnóstico precoz ni de tratamientos efectivos, especialmente en fases avanzadas de la enfermedad, por lo que resulta esencial desvelar los eventos biológicos que subyacen a la caquexia asociada a cáncer. En este trabajo trataremos de abordar la identificación de biomarcadores y dianas moleculares desde la perspectiva teórica partiendo de la fisiopatología y los estudios actuales
Cachexia is a multifactorial metabolic disorder characterized by involuntary weight loss, mainly at the expense of muscle and adipose tissue, that affects more than half of cancer patients. Systemic inflammation, release of substances by the tumor and other neuroendocrine factors contribute to create a metabolic state characterized by a high energy expenditure, where catabolic processes such as proteolysis and lipolysis predominate with a clear clinical reflex. Presently, no biomarkers are available for early diagnosis or effective treatments, particularly in advanced stages of the disease, so it is essential to uncover the biological events underlying cancer-associated cachexia. In this work we will try to address the identification of biomarkers and molecular targets from a theoretical perspective based on the physiopathology and the current studies
