Abstract
For the ovarian cancer diagnosis with biomarkers in urine samples, various calibration functions are selected and investigated to compensate the variability of their concentrations. The 15 biomarkers tested in this paper were extracted and measured for the urine samples of 178 patients. Three types of functions were employed to calibrate the biomarkers, including the existing one that divides the biomarker concentration by that of the creatinine. The AUC of the ROC of the calibrated biomarker with each function was chosen to evaluate the performance. Experimental results show that the best performance could be obtained by dividing the concentration of the biomarker by that of the creatinine raised to the power of the optimal exponent that was determined for the maximum AUC of the calibrated biomarker.
