AJCC/UICC 8th Edition Head and Neck Staging Changes

This content delves into the changes in staging guidelines for head and neck malignancies as per the 8th edition of the AJCC/UICC criteria. It explores the modifications in staging for oropharynx cancer, neck metastatic disease, oral cavity depth of invasion, and cutaneous malignancies. The presentation touches on the importance of hazard discrimination, balance between patient groups, and the high predictive ability of the staging system. Additionally, it discusses specific aspects such as p16-positive versus p16-negative oropharynx squamous cell carcinoma patients, different staging for these subcategories, and the impact of minimally invasive transoral approaches in oropharynx cancer treatment. The content also mentions studies and research publications that have contributed to the refinement of staging classifications for head and neck cancers.
