摘要

The prognosis and treatment plans for patients diagnosed with low‐grade gliomas (LGGs) may significantly be improved if there is evidence of chromosome 1p/19q co‐deletion mutation. Many studies proved that the codeletion status of 1p/19q enhances the sensitivity of the tumor to different types of therapeutics. However, the current clinical gold standard of detecting this chromosomal mutation remains invasive and poses implicit risks to patients. Radiomics features derived from medical images have been used as a new approach for non‐invasive diagnosis and clinical decisions. This study proposed an eXtreme Gradient Boosting (XGBoost)‐based model to predict the 1p/19q codeletion status in a binary classification task. We trained our model on the public database extracted from The Cancer Imaging Archive (TCIA), including 159 LGG patients with 1p/19q co‐deletion mutation status. The XGBoost was the baseline algorithm, and we combined the SHapley Additive exPlanations (SHAP) analysis to select the seven most optimal radiomics features to build the final predictive model. Our final model achieved an accuracy of 87% and 82.8% on the training set and external test set, respectively. With seven wavelet radiomics features, our XGBoost-based model can identify the 1p/19q codeletion status in LGG‐diagnosed patients for better management and address the drawbacks of invasive gold‐standard tests in clinical practice.
