The aim of the study was to evaluate the effect of laparoscopic-based score combined with a multiple disciplinary team (MDT) for predicting optimal cytoreduction and perform personalized surgical treatment in recurrent ovarian cancer (ROC).

The study is a single-center, prospective investigation. From March 2013 to May 2015, the consecutive treated patients with platinum-sensitive ROC were collected in Yangpu Hospital. The appropriated patients were enrolled into the study to perform the laparoscopic-based PIV (predictive index value) score assessment with an MDT for predicting optimal cytoreduction. The PIV cutoff value was confirmed to be 8. Patients of PIV <8 received laparoscopic/laparotomy secondary surgery following chemotherapy, and the ones with PIV ≥8 did chemotherapy alone. Sensitivity, specificity, positive predicted value (PPV), negative predicted value (NPV), and overall accuracy for each range of PIV score were calculated. All recruited patients participated in follow-up observation. Overall survival was recorded.

In total, 58 eligible ROC patients received laparoscopy assessment. Forty-one patients of PIV <8 received secondary cytoreductive surgeries. Twenty-three (23/41 56.1%) attained optimal cytoreduction. However, 8 of 23 achieved completed cytoreduction. Also, 17 patients of PIV ≥8 underwent chemotherapy alone. Sensitivity, specificity, PPV, NPV, and overall accuracy for PIV ≥8 were 60%, 100%, 100%, 25%, and 64.7%, respectively. Overall survival in patients performing optimal cytoreduction was significantly higher than in those undergoing suboptimal cytoreduction or chemotherapy alone (45.9 ± 2.5 vs 36.7 ± 4.3 months, P = .047; 45.9 ± 2.5 vs 35.8 ± 3.4 months, P  = .027).

Laparoscopic-based score assessment plus MDT helps to identify the appropriate patients to perform optimal secondary cytoreduction and provide a personalized surgical approach in management of ROC.
