Table 3 Diagnostic parameters for SCS by technique

From: Prediction of suboptimal cytoreductive surgery in patients with advanced ovarian cancer based on preoperative and intraoperative determination of the peritoneal carcinomatosis index

  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)
  1. SCS suboptimal cytoreductive surgery, 95%CI 95% confidence interval, SEN sensitivity, SPC specificity, PPV positive predictive value, NPV negative predictive value, CT computed tomography
  2. aFor an SCS prevalence of 13.8%
  3. bCriteria for SCS: CT plus laparoscopy positive for SCS if both show a PCI of > 20
