Description:
Objective: Accurate prognostic stratification of Head-and-Neck-Squamous-Cell-Carcinoma (HNSCC) patients can be an important clinical reference when designing therapeutic strategies. We set to predict 4 outcomes: overall-survival (OS), distant-metastasis (DM), loco-regional-recurrence (LR), and progression-free-survival (SP). We studied hybrid-machine-learning-systems (HMLS) incorporating multiple dimensionality reduction as well as survival prediction algorithms, applied to datasets with radiomics-features. Methods: In this multi-center-study, 408 HNSCC patients were extracted from the Cancer-Imaging-Archive. PET images were registered to CT, enhanced, and cropped. 215 radiomics features were extracted from each region-of-interest via our standardized SERA radiomics package. We employed multiple HMLSs: 14 feature-extraction (FEA) or 10 feature-selection-algorithms (FSA) linked with 8 survival-prediction-algorithms (SPA) optimized by 5-fold cross-validation, applied to PET-only, CT-only and 4 PET-CT datasets generated by image-level fusion strategies. Datasets were normalized by Z-score-technique, with c-index reported to compare models.
