Diagnostic parameters for SCS by technique
| SEN (95% CI) | SPC (95% CI) | PPVa (95% CI) | NPVa (95% CI) | |
|---|---|---|---|---|
| CT scan | 27% (6–61) | 91% (82–97) | 33% (8–70) | 89 (79–95) |
| Laparoscopy | 38% (9–76) | 88% (74–96) | 33% (6–73) | 90 (76–97) |
| Laparotomy | 73% (39–94) | 81% (70–90) | 38% (18–62) | 95% (86–99) |
| CT plus laparoscopyb | 38% (14–69) | 98% (87–99) | 75% (27–98) | 91% (82–96) |
SCS suboptimal cytoreductive surgery, 95%CI 95% confidence interval, SEN sensitivity, SPC specificity, PPV positive predictive value, NPV negative predictive value, CT computed tomography
aFor an SCS prevalence of 13.8%
bCriteria for SCS: CT plus laparoscopy positive for SCS if both show a PCI of > 20
