Abstract

Background: Sarcopenia is one of the early pathological manifestations of cancer cachexia. This change in quality and function has a general and special impact on the prognosis of many types of tumors. However, there are few studies to evaluate the overall impact of sarcopenia on the prognosis of gynecological tumors in sufficient follow-up period.

Methods: This study systematically searched PubMed, EMBASE, web of science, and MEDLINE databases for related studies and related references since April 15, 2021. The 1-year, 5-year overall survival (OS), progression-free survival (PFS), hazard ratio (HR), and 95% confidence interval (CI) were analyzed by Stata 14.0.(CRD 42021236036).

Results: A total of 23 observational studies involving 3495 female patients were included in the analysis, with an average prevalence of 46.9% (38.5%-55.3%). Meta-analysis showed that the 1-year OS (RR: 1.60, 95% CI = [1.04, 2.46]) of patients with sarcopenia was significantly lower than that of patients without sarcopenia, and then this effect gradually decreased. The results showed that sarcopenia was an independent predictor of OS (HR: 1.78, 95% CI = [1.38, 2.30]) and PFS (HR: 1.32, 95% CI = [1.02, 1.70]) in gynecological cancer patients. Subgroup analysis showed that sarcopenia was significant in Asian population (HR: 1.93, 95% CI = [1.18, 3.17]) and cervical cancer patients (HR: 5.07, 95% CI = [2.82, 9.56]).

Conclusion: The survival and recurrence outcome of patients with sarcopenia independently related to surgery, and its impact is very obvious in the short term. In addition, Asian participants with sarcopenia face a greater risk of death than Western participants.
