ABSTRACT
The aim of the study was to determine if diagnostic performance of CA-125 in ovarian malignancy can be improved by considering age of the patient. The study was a retrospective analysis of the medical records of 306 patients who underwent a CA-125 measurement in our Institute. Of the 306 patients, 31% had malignant ovarian diseases, 45% had benign ovarian diseases, 6% had non-ovarian gynaecological diseases and 18% had non-gynaecological diseases. A positive association was found between age and CA-125 levels in patients with ovarian diseases. Patients were divided into three age groups of 18–37 yrs, 38–56 yrs and 57–74 yrs and were given age scores as 1, 2 and 3 respectively. Biochemical predictive index (BPI) was calculated by multiplying age score and CA-125 value. Among the age groups ranging 38–56 yrs and 57–74 yrs, the CA-125 and BPI values were significantly higher in malignant ovarian diseases compared to benign ovarian diseases. ROC curve analysis revealed a cut-off of 86 for the BPI with the sensitivity, specificity, positive predictive value and negative predictive value as 58%, 78%, 56% and 80% respectively. BPI had better specificity and negative predictive value compared to CA-125, can be used in the screening of ovarian pathology.
