Clinical impact of CT-defined sarcopenia on long-term oncological outcomes in gastric cancer: validation of muscle mass cut-offs established according to EWGSOP recommendations.
BACKGROUND Sarcopenia is an important prognostic factor in gastrointestinal malignancies, but CT-based definitions vary. This study evaluated recently published computed tomography (CT)-based cut-offs for skeletal muscle index (SMI) and psoas muscle thickness normalized to height (PMTH), derived from a young, presumabl...
