Makine öğrenmesi, ağız lökoplakisi malign transformasyonunu 5 yıl içinde tahmin ediyor

Özet (abstract)

Background Oral leukoplakia (OLK), a potentially malignant oral disorder, has 7.2 − 9.8 % transformation rate. Identifying high-risk patients within 5 years can reduce the oral cancer burden. Objective In this retrospective study, we aimed to identify the factors associated with malignant transformation in Chinese patients with OLK and develop and evaluate machine learning (ML) models for predicting malignant transformation within 5 years. Methods In total, 672 OLK patients (203 showing transformation; 469 with no transformation) were included. Logistic Regression, SVM, Random Forest, GBDT, XGBoost, and LightGBM ML algorithms were used to develop models based on 17 clinicopathological features and evaluated using an internal test set and a temporal validation cohort of 73 patients (24 showing transformation; 49 with no transformation). Results LightGBM showed the best overall performance in the internal test set (accuracy, 82.65 %; area under the curve (AUC), 0.8524), and it maintained good discriminative performance in the temporal validation cohort (AUC, 0.7959) when 17 clinicopathological features were used. XGBoost showed the best performance in both the internal test set (AUC, 0.8081) and temporal validation cohort (AUC, 0.8092) when five clinicopathological features were used. While predicting malignant transformation within 5 years, XGBoost achieved an AUC of 0.8505 in the internal test set. However, the temporal validation results should be interpreted with caution because of limited sample size. Conclusion ML models may predict malignant transformation within 5 years in patients with OLK and may assist in individualized risk stratification. Further validation in larger multicenter cohorts is required before clinical application.
