Table 5 Predictive values depending on prevalence of SCS (CT + laparoscopy)

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

SCS: prevalence SCS: PPV SCS: NPV
10% 68% (17–98) 93% (85–98)
20% 83% (40–99) 86% (76–93)
30% 89% (55–99) 79% (67–88)
40% 93% (65–99) 70% (58–81)
50% 95% (72–99) 61% (48–73)
  1. For sensitivity of 38% and specificity of 98%
  2. SCS suboptimal cytoreductive surgery, CT computed tomography, PPV positive predictive value, NPV negative predictive value
