The Ability Pre-operative Serum (Cancer Antigen-125, Fatty Acid Synthase, and Glucose Transporter) to Predict Primary Suboptimal Cytoreduction in Epithelial Ovarian Cancer

BACKGROUND: The incidence of ovarian cancer ranks 8th in the world, with 295,414 cases and 184,799 death in 2018. Management in ovarian cancer is surgery and chemotherapy. Some studies state that patients who underwent optimal cytoreduction surgery have better survival rates than suboptimal cytoreduction surgery. The pre-operative serum assessed in this study was Cancer Antigen-125 (CA-125), Fatty Acid Synthase (FASN), and Glucose Transporter (GLUT) to predict suboptimal cytoreduction in epithelial ovarian cancer (EOC). AIM: We aimed to use FASN and GLUT1 as other biomarkers, besides CA-125, to predict suboptimal cytoreduction surgery in epithelial ovarian cancer. METHODS: This observational-analytic cross-sectional study included 109 women diagnosed with epithelial ovarian cancer (EOC) between 2017 and 2019, who had serum CA-125, FASN, and GLUT measured preoperatively and underwent cytoreductive surgery. RESULTS: The results of the statistical analysis test in this study obtained p values at CA-125 (p = 0.0001), FASN (p = 0.017), and at GLUT (p = 0.013). While the cutoff point (COP) on CA-125 was 248.55, FASN was 0.445, and GLUT was 0.1980. The value of area under curve (AUC) obtained by the ROC method at CA-125 76.7%, FASN 65.3%, and GLUT 63.8%. The combination of CA-125 and FASN shows AUC value 76.9%, the combination of CA-125 and GLUT shows AUC value 72.2%, and the combination of the three shows AUC value 75.2%. CONCLUSION: The use of CA-125 as a predictor of cytoreduction surgery is still considered to be the best predictor compared to serum biomarkers in this study.
