| Factor | Cut-off value | Sensitivity (%) | Specificity (%) | AUC | P |
|---|---|---|---|---|---|
| CA-125 (U/ml) | 76.56 | 60.00 | 85.56 | 0.754 | <0.001 |
| CA-153 (U/ml) | 22.33 | 70.00 | 82.76 | 0.790 | <0.001 |
| CYFRA21-1(ng/ml) | 10.70 | 72.00 | 87.09 | 0.838 | <0.001 |
| CA-125+CA-153 | - | 74.00 | 81.89 | 0.827 | <0.001 |
| CA-125+CYFRA21-1 | - | 74.00 | 84.12 | 0.834 | <0.001 |
| CA-153+CYFRA21-1 | - | 80.00 | 80.45 | 0.850 | <0.001 |
| CA-125+CA-153+CYFRA21-1 | - | 82.00 | 82.92 | 0.859 | <0.001 |
Notes: Sensitivity and specificity were obtained at the point of cutoff value. P <0.05 represented statistically significant. Abbreviations: AUC, area under the curve; CI, confidence interval; OM, ocular metastasis.
