Artificial Intelligence in Imaging-Based Extranodal Extension Detection: Advancing Prognostication in HPV-Positive Oropharyngeal Cancer

MedXY Editorial Team•Oct 22, 2025•AI

An AI-driven imaging pipeline was developed to automatically segment lymph nodes and classify extranodal extension (iENE) on pretreatment CT scans in HPV-positive oropharyngeal carcinoma (OPC).
The AI model achieved high accuracy (AUC 0.81) in detecting iENE compared to evaluations by expert neuroradiologists, addressing limitations of subjective imaging interpretation.
AI-predicted iENE was independently associated with worse overall survival, recurrence-free survival, and distant control, outperforming radiologist assessments in prognostic discrimination.
This approach offers a reproducible, scalable tool for risk stratification in HPV-positive OPC, highlighting the potential of AI to enhance personalized treatment planning.
