Background/Objectives: Sarcopenia is an emergent prognostic biomarker in clinical oncology. Albeit increasingly defined through skeletal muscle index (SMI) thresholding, literature cut-offs fail to discern heterogeneous baseline muscularity across populations. This study assesses the impact of using cohort-specific SMI thresholds a Portuguese metastatic non-small-cell lung cancer (mNSCLC) cohort. Methods: Retrospective including mNSCLC patients treated between January 2017 and December 2022....
