Ovarian Malignancy Prediction by Gatot Purwoto (GP) Score, Risk Malignancy Index (RMI), and Frozen Section in Young Age
Prediksi Keganasan Ovarium dari Skor Gatot Purwoto (GP), Risk Malignancy Index (RMI), dan Potong Beku pada Usia Muda
Objective: To know the diagnostic value of a scoring system taken before surgery and frozen section in young-aged patients with suspected malignancy. Using that result, we can also investigate whether frozen section gives additional value to clinical scoring system.
Method: This study is a diagnostic test. This study was carried out by accessing RSCMâ€™s medical record from 2006-2011. From 437 patients suspected of ovarian malignancy, we included 157 patients due to age.
Result: Diagnostic value of GP score are 77%, 49%, 61%, 68%, 63%, while RMI are 69%, 49%, 58%, 45%, 59%, (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy respectively). Diagnostic value of frozen section in patients with suspected malignancy using GP score >4 are 81.7%, 87.2%, 90.7%, 75.6%, 83%, while in patients with RMI 200 are 81%, 87%, 89%, 77%, 83% (sensitivity, spesificity, positive predictive value, negative predictive value, and accuracy respectively).
Conclusion: Gatot Purwoto score and RMI have good diagnostic value in proving malignancy in young age. Its predictive value will be increased by frozen section.
