Aim:
To evaluate the relevance of laparoscopic index of Fagotti et al during staging laparoscopy (S-LPS) to predict optimal cytoreduction during interval debulking surgery (IDS) after neoadjuvant chemotherapy for ovarian cancer.
Patients And Methods:
Fifty-two patients with stage III-IV ovarian cancer were retrospectively analyzed. We evaluated discrimination with a receiver operating characteristic (ROC) curve analysis and calibration of Fagotti et al's model among our population and compared this performance with their data.
Results:
A score >4 was associated with optimal resection with sensitivity and positive predictive value (PPV) of 95% and 82% respectively. The ROC curve analysis gave an area under the curve (AUC) of 0.72 (95% confidence interval (CI) 0.65-0.80) for our population compared to 0.88 (95% CI 0.84-0.91) in Fagotti et al's population. Percentages predicted in our population were unsatisfactory (p<0.01), illustrating the different rates of optimal cytoreduction between the centers (average error of 25%).
Conclusion:
The laparoscopic index of Fagotti et al is relevant in prediction of optimal cytoreduction among women undergoing IDS.
