Sarcopenia was reported as a prognostic factor in cancer patients. Using computed tomography (CT), we analyzed the impact of sarcopenia on overall survival (OS) in patients with advanced epithelial ovarian cancer (EOC) after primary debulking surgery (PDS). Preoperative CT scans of consecutive EOC patients (n = 323) were retrospectively assessed for skeletal muscle index (SMI) and muscle attenuation (MA;Hounsfield units [HU]). The optimal cut-off point for MA (32 HU) was calculated using the Martingale residuals method, and previously reported cut-offs for SMI were used. Logistic regression was used to determine univariate and multivariate factors associated with OS. Sarcopenia defined as SMI < 38.5, < 39, and 41 cm(2)/m(2) was detected in 29.4, 33.7, and 47.1% of patients, respectively;however, none of these SMI cut-off levels were associated with OS. MA < 32 HU was present in 21.1% (68/323) of the total cohort. Significant differences between patients with MA < 32 and 32 HU were detected for median age (67 vs. 57 years), Eastern Cooperative Oncology Group (ECOG) > 0 (13.2 vs. 3.1%), comorbidity (age-adjusted Charlson Comorbidity Index [ACCI] 4;36.8 vs. 13.3%), median body mass index (BMI;27 vs. 24 kg/m(2)), International Federation of Gynecology and Obstetrics (FIGO) stage, histology (high-grade serous 95.6 vs. 84.7%), and complete resection (38.2 vs. 68.2%). MA < 32 HU remained a significant prognostic factor for OS in multivariate Cox regression analysis (hazard ratio 1.79, p = 0.003). Median OS in patients with MA < 32 HU versus MA 32 HU was 28 versus 56 months (p < 0.001). Furthermore, MA < 32 HU was significantly associated with OS in the prognostically poor population of patients with residual tumor (p = 0.015). Low MA was significantly associated with poor survival, especially in patients with residual tumor after PDS. MA assessment could be used for risk stratification after PDS.
