Abstract

Abstract: Background: Prediction of survival and radiation therapy response is challenging in head and neck cancer with metastatic lymph nodes (LNs). Here we developed novel radiomics‐ and clinical‐based predictive models. Methods: Volumes of interest of LNs were employed for radiomic features extraction. Radiomic and clinical features were investigated for their predictive value relatively to locoregional failure (LRF), progression‐free survival (PFS), and overall survival (OS) and used to build multivariate models. Results: Hundred and six subjects were suitable for final analysis. Univariate analysis identified two radiomic features significantly predictive for LRF, and five radiomic features plus two clinical features significantly predictive for both PFS and OS. The area under the curve of receiver operating characteristic curve combining clinical and radiomic predictors for PFS and OS resulted 0.71 (95%CI: 0.60–0.83) and 0.77 (95%CI: 0.64–0.89). Conclusions: Radiomic and clinical features resulted to be independent predictive factors, but external independent validation is mandatory to support these findings.
