Abstract
Altered eating behavior, intended as the reduction or loss of the desire to eat, represents a frequent symptom and one of the most common health-related problems, with clinical and psychological consequences in many cancer patients.
The pathophysiology of cancer anorexia is complex and involves different domains influencing eating behavior and affecting peripheral and/or central mechanisms.
Identifying patients at risk to develop anorexia remains a challenge for most physicians due to several reasons, including the different way each patient describes the anorexia symptoms (quantitatively and qualitatively) and due to the absence of widely accepted validated appetite assessment tools. In this light, the risk to underestimate this condition among cancer patients is high, and this may negatively impact on patient’s prognosis and quality of life.
Effective therapeutic options for cancer anorexia are still scanty, although some clinical trials were recently conducted to test the efficacy of novel promising molecules.
The correct identification of low appetite and impaired food intake in cancer may help physicians to implement tailored treatments aimed at avoiding the development of body weight loss and protein-energy malnutrition.
