TLDR A standardized scoring system is needed to improve model reliability for predicting hair loss in brain tumor patients treated with proton therapy.
The study highlights the challenges in validating NTCP models for radiation-induced alopecia (RIA) in brain tumor patients treated with pencil scanning proton therapy. Although the models show reasonable sensitivity and specificity, discrepancies between the cohorts used for model development and validation pose significant issues. These differences, particularly in the reporting of clinical outcomes, undermine the reliability of the models. The study concludes that a standardized and objective RIA scoring system is crucial for improving model validation.
