Advanced radiotherapy treatments for Oropharyngeal cancer have improved patient survival rates, although they lead to understudied long-term symptoms. By analyzing three-dimensional dose distributions to vital organs via custom unsupervised machine learning, we identify correlations with long-term patient-reported symptoms. Our innovative approach surpasses existing clinical guidelines, offering actionable insights for optimizing treatment plans and minimizing post-treatment side effects.
