Abstract

Objective: To investigate whether patients' altered body composition (measured with bioimpedentiometry), due to a poor nutritional status, predicts the incidence of no residual disease at primary debulking and the risk of complications in patients with newly-diagnosed advanced epithelial ovarian cancer (EOC). Methods: Data regarding patients with newly-diagnosed stage IIIC-IV EOC undergoing elective nutritional assessment between December 2016 and March 2017, were prospectively collected. Bioelectrical impedance analysis (BIA) with measurement of BIA-derived phase angle [PhA] at 50 KHz, was accomplished. Only patients with disease which was considered resectable at staging laparoscopy were submitted to open primary cytoreduction. The rate of residual tumor (RT) = 0 and the incidence of complications were assessed. Results: Seventy patients were included. Fifty-two of them were submitted to primary cytoreduction (74.3%) and 48 (68.6% of the entire cohort, 92.3% of those who underwent primary debulking) had RT = 0 at the end of surgery. Median values of PhA were significantly lower in patients with RT > vs. =0 (4.7, range: 3.6–5.8 vs. 5.3, range: 4.2–6.8; p = 0.001). Twenty-four (out of the 52 operated) patients (46.2%) developed at least one complication. PhA was significantly lower in patients with vs. without complications (5, range: 3.6–6.4, vs. 5.4, range 4.5–6.8; p = 0.03). After multivariable analysis, Fagotti score and PhA were the only independent predictors of residual disease (OR:13.56; 95%CI:1.33–137.6; p = 0.027 and 9.24; 1.16–73.43; p = 0.036, respectively) and of any complication (OR:4.9;95%CI:1.17–20.6; p = 0.03 and 7.27; 1.45–36.4; p = 0.01, respectively). Conclusions: Derangement of body composition (likely due to disease-related malnutrition) expressed as a low phase angle, is an independent predictor of residual disease and peri-operative complications at the time of upfront cytoreduction for advanced EOC.
