Objective: To assess the association between loss of lumbar skeletal muscle mass and density during neoadjuvant chemotherapy (NACT) and postoperative complications after interval cytoreductive surgery (CRS) in older patients with ovarian cancer., Materials and Methods: This multicenter, retrospective cohort study included patients aged 70 years and older with primary advanced stage ovarian cancer (International Federation of Gynecology and Obstetrics stage III-IV), treated with NACT and interval CRS. Skeletal muscle mass and density were retrospectively assessed using Skeletal Muscle Index (SMI) and Muscle Attenuation (MA) on routinely made Computed Tomography scans before and after NACT. Loss of skeletal muscle mass or density was defined as >2% decrease per 100 days in SMI or MA during NACT., Results: In total, 111 patients were included. Loss of skeletal muscle density during NACT was associated with developing any postoperative complication ≤30 days after interval CRS both in univariable (Odds Ratio (OR) 3.69; 95% Confidence Interval (CI) 1.57-8.68) and in multivariable analysis adjusted for functional impairment and WHO performance status (OR 3.62; 95%CI 1.27-10.25). Loss of skeletal muscle density was also associated with infectious complications (OR 3.67; 95%CI 1.42-9.52) and unintended discontinuation of adjuvant chemotherapy (OR 5.07; 95%CI 1.41-18.19). Unlike loss of skeletal muscle density, loss of skeletal muscle mass showed no association with postoperative outcomes., Conclusion: In older patients with ovarian cancer, loss of skeletal muscle density during NACT is associated with worse postoperative outcomes. These results could add to perioperative risk assessment, guiding the decision to undergo surgery or the need for perioperative interventions., Competing Interests: Declaration of competing interest None., (Copyright © 2021 The Authors.

Objective: Patients with peripheral arterial occlusive disease (PAOD) have a poor prognosis and a high prevalence of comorbidity. This study investigated whether sarcopenia and/or myosteatosis negatively affect long-term survival in patients with PAOD., Methods: This was a single-center, retrospective cohort study of 686 consecutive patients diagnosed and treated for PAOD and who underwent computed tomography scanning. Cross-sectional muscle measurements were obtained at the level of the third lumbar vertebra. Optimal stratification was used to define sex-specific and body mass index-specific cutoff values for sarcopenia and myosteatosis, respectively. The Cox proportional hazards model was used to determine the effect of sarcopenia and myosteatosis on overall survival., Results: Sarcopenia was associated with age, body mass index, myosteatosis, malignancy, congestive heart failure, hemodialysis, and Fontaine 4 classification. Myosteatosis was associated with age, sarcopenia, type 2 diabetes mellitus, hypertension, chronic obstructive pulmonary disease, malignancy, congestive heart failure, ischemic stroke, and Fontaine 4 classification. Sarcopenia (hazard ratio [HR], 2.82; 95% confidence interval [CI], 2.05-3.86; P < .001) and myosteatosis (HR, 4.13; 95% CI, 3.03-5.63; P < .001) were both associated with reduced survival in univariable analysis. When adjusted for other prognostic markers, myosteatosis (HR, 2.09; 95% CI, 1.46-2.99; P < .001) was still associated with lower overall survival in the multivariable model, but sarcopenia (HR, 1.40; 95% CI, 0.97-2.01; P = .073) was not., Conclusions: Muscle depletion is independently associated with a poorer overall survival in patients with PAOD. Myosteatosis is a stronger predictor than sarcopenia, which indicates that quality is more important than quantity. Results should be interpreted with caution owing to missing data on medication usage., (Copyright © 2020 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)
