Table 3 The predictive accuracy of preoperative serum CEA, CA19-9, and adjusted CA19-9 concentrations for gallbladder cancer respectability.
| Resectability (R0 resection) | |||
|---|---|---|---|
| CEA <4.05 ng/mL | CA19-9 <78.5 U/mL | Adjusted CA19-9 <47.63 U/mL | |
| No. patients | 169 | 150 | 153 |
| Sensitivity (%) | 66.90 | 64.50 | 69.82 |
| Specificity (%) | 60.00 | 70.70 | 75.00 |
| PPV (%) | 66.90 | 72.67 | 77.12 |
| NPV (%) | 60.00 | 62.26 | 67.31 |
| CA19-9 – carbohydrate antigen 19-9; CEA – carcinoembryonic antigen; PPV – positive predictive value; NPV – negative predictive value. | |||
