Popis: Abstract Background Malignant ascites is prevalent in advanced‐stage ovarian cancer and may facilitate identification of the drivers of muscle loss. This study aimed to evaluate the association of ascites with changes in systemic inflammation and muscle after treatment of advanced‐stage ovarian cancer. Methods We evaluated 307 patients with advanced‐stage (III/IVA) ovarian cancer who underwent primary debulking surgery and adjuvant platinum‐based chemotherapy between 2010 and 2019. The changes in skeletal muscle index (SMI) and radiodensity (SMD) were measured using pre‐surgery and post‐chemotherapy portal‐venous phase contrast‐enhanced computed tomography scans at L3. Systemic inflammation was measured using albumin levels, prognostic nutritional index (PNI), neutrophil‐lymphocyte ratio (NLR), and platelet‐lymphocyte ratio (PLR). Primary endpoint was the changes in SMI and SMD after treatment. Linear regression analysis was used to test associations between muscle change and other covariates. Mediation analysis was used to determine the mediator. Results The median (range) age was 53 (23–83) years. The median duration (range) of follow‐up was 5.2 (1.1–11.3) years. Overall, 187 (60.9%) patients had ascites. The changes in muscle and systemic inflammatory markers after treatment were significantly different between patients with and without ascites (SMI: −3.9% vs. 2.2%, P
