Compartmentalized Postoperative Radiotherapy in Head and Neck Cancer

COMPORT is a multicenter phase II clinical trial evaluating a personalized approach to postoperative radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC). The study investigates whether a risk-adapted, compartmentalized radiotherapy strategy can safely reduce the treatment volume, and thus the side effects, without increasing the risk of tumor recurrence. Eligible patients are those with surgically treated cancers of the oral cavity, oropharynx, larynx, or hypopharynx who have a standard indication for postoperative radiotherapy. The primary outcome is the rate of recurrence in anatomical compartments that would normally be irradiated but are intentionally omitted in this study. COMPORT aims to generate high-level evidence to support a more personalized and less toxic standard of care in postoperative head and neck cancer management.
