Sarcopenia in Terminally Ill Patients with Cancer: Clinical Implications, Diagnostic Challenges, and Management...

Sarcopenia, characterized by progressive loss of skeletal muscle mass and strength, is a prevalent but often overlooked condition in patients with cancer who are terminally ill. It contributes to functional decline, increased symptom burden, and reduced quality of life, yet remains underrecognized in palliative care. Diagnosing sarcopenia in this population is challenging because conventional imaging techniques are often impractical. Instead, alternative assessments, such as the Strength, Assistance with walking, Rise from a chair, Climb stairs, and Falls questionnaire (SARC-F), anthropometric measurements, and bioelectrical impedance analysis offer feasible options. Management should focus on symptom relief, functional preservation, and patient comfort, rather than on muscle mass restoration. Nutritional support must be tailored to prognosis, with aggressive interventions generally avoided during end-of-life care. Although exercise may help to maintain mobility and alleviate symptoms, its feasibility is often limited. Pharmacological interventions, including appetite stimulants and anti-cachexia agents, remain largely investigational, with insufficient evidence for routine use in palliative care. Future research should refine sarcopenia assessment methods and develop patient-centered interventions that align with palliative care principles, emphasizing quality of life and individualized needs.
