Significance of Pretreatment C-Reactive Protein, Albumin, and C-Reactive Protein to Albumin Ratio in Predicting Poor Prognosis in Epithelial Ovarian Cancer Patients.

To investigate the prognostic significance of pretreatment C-reactive protein (CRP), albumin, and the CRP to albumin ratio (CRP/Alb) in epithelial ovarian cancer (EOC) patients. Clinical data from 308 EOC patients between April 2007 and March 2016 were collected and retrospectively reviewed. The cutoff values for CRP, albumin, and CRP/Alb were defined by receiver operating characteristics (ROC) analyses. Univariate or multivariate analysis was conducted to evaluate the prognostic significance of these factors for disease-specific survival. The cutoff values for CRP, albumin, and CRP/Alb were 0.76, 3.8, and 0.048 by ROC analysis, respectively. Cox regression analyses demonstrated that an elevated CRP/Alb is an independent predictor of short disease-specific survival irrespective of clinical stage or optimal surgery rate. When examined according to clinical stage, elevated CRP/Alb was associated with short disease-specific survival in both early-stage and advanced-stage patients. Cox regression analyses demonstrated that an elevated CRP, but not lower albumin, is also an independent predictor of short disease-specific survival. When two prognosticators were compared, CRP/Alb was found to be superior to CRP for predicting disease-specific survival in EOC patients. Pretreatment elevated CRP/Alb is a predictor of shorter survival in EOC patients regardless of clinical stage.
