Sarcopenia in long‐term survivors of cancer in childhood and adolescence: A cross‐sectional study of calf muscle mass by peripheral quantitative computed tomography with an examination of the muscle–bone unit

BACKGROUND: Sarcopenia, a loss of systemic skeletal muscle mass (SMM), is prevalent in childhood cancer survivors and often accompanied by increased fat mass (sarcopenic obesity [SO]). We examined whether calf muscle cross-sectional area (CSA), measured by peripheral quantitative computed tomography (pQCT), can identify sarcopenia and SO in long-term survivors of pediatric acute lymphoblastic leukemia (ALL), and explored its relationship with …
