Image biomarkers to improve prediction of treatment outcome
Image biomarkers of CT imaging of head and neck tumors and lymph nodes to improve the prediction of survival and local-regional control
Recent studies have demonstrated that image biomarkers are significantly associated with treatment outcome. We tested whether the performance of prediction models for local recurrence, regional recurrence, disease free survival and overall survival could be improved by the addition of image biomarkers. Using these image biomarkers, we will furthermore focus on the pre-treatment patient-individual prediction of various endpoints.
Examples of patients with low (C) and high (D) values of Run Length Non-uniformity of the tumor. Examples of Major-axis-length in patients with two unilateral (E) and two bilateral (F) positive lymph nodes.
