A Combined Model to Improve the Prediction of Local Control for Lung Cancer Patients Undergoing Stereotactic Body Radiotherapy Based on Radiomic Signature Plus Clinical and Dosimetric Parameters

Abstract: PurposeStereotactic body radiotherapy (SBRT) is an important treatment modality for lung cancer patients, however, tumor local recurrence rate remains some challenge and there is no reliable prediction tool. This study aims to develop a prediction model of local control for lung cancer patients undergoing SBRT based on radiomics signature combining with clinical and dosimetric parameters.MethodsThe radiomics model, clinical model and combined model were developed by radiomics features, incorporating clinical a… Show more

“…However, we did not observe a similar trend in the validation cohort due to limited sample size. This finding is consistent with other studies (Luo et al 2021 ; Zhai et al 2020 , 2017 ) and the result indicates that multi-omics features contribute to improve the prediction accuracy of radiation therapy models (Cui et al 2021 ).…”

“…and Li et al. also proposed that clinical variables were significantly correlated with the clinical outcomes of patients receiving SBRT for lung cancer and proved that the combined model based on clinical factors and radiomics features could effectively improve model prediction efficiency ( 34 , 35 ).…”

“…Even so, compared with the ROC, the AUC value of the combined model is higher than that of the pure CT radiomics model. Therefore, clinical variables (the type of peritumoral RILI) still have a specific positive effect on the comprehensive judgment of (34,35).…”

“…In this study, p values < 0.05 were considered as significant level. Ultimately, the optimal cut-off point for selected features in the best prediction model was determined by maximizing Youden's index on the ROC curve [ 35 ].…”
