Sarcopenia is closely associated with poor prognosis of patients with cancer; however, there is a significant gap in the current clinical knowledge of tumor-related sarcopenia and the means to prevent and control it. The aim of this study is to explore the prevalence and influencing factors of tumor-related sarcopenia through a scoping review, and to provide guidance for future research directions and the development of intervention protocols.<h4>Methods</h4>Using computerized search methods, we extensively searched multiple authoritative databases, includinBMC cancer426https://www.ebi.ac.uk/biostudies/studies/S-EPMC11892265biostudies-literatureThe influencing factors of tumor-related sarcopenia: a scoping review.PMC11892265Gao YTian CYan YLi NfalseThe influencing factors of tumor-related sarcopenia: a scoping review.<h4>Background and objective</h4>As the number of cancer cases is increasing dramatically worldwide, patients with cancer are facing serious threats of nutritional loss, sarcopenia, and even cachexia in the early stages of the disease.
