Statistical interpretation of CA125 and Bcl-2 in serum of patients with late stage ovarian cancer.

摘要

OBJECTIVES: The present study was conducted to investigate the sensitivity, specificity, predictive values and accuracy of serum CA125 and Bcl-2 levels and their combination in advanced epithelial ovarian cancer patients. METHODS: Healthy controls (n = 117) with no gynecologic problems and patients with ovarian carcinoma (n = 117), pathologically verified, consecutively admitted to the Istanbul University, Oncology Institute during a one-year period were investigated. Serum Bcl-2 and CA125 were determined by using enzyme linked immunosorbent assay method. RESULTS: The serum bcl-2 and CA125 levels were significantly higher in patients with ovarian cancer than in the control group (P < 0.001). The diagnostic sensitivity and specificity, predictive values and accuracies were calculated for each marker and their combination. CONCLUSION: The best result was achieved with the combination of CA125-bcl-2. This combination fulfills the need of diagnosis of ovarian carcinoma for the best sensitivity and specificity.
