Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Volume and Dose De-Intensified Radiotherapy for p16+ Squamous Cell Carcinoma of the Oropharynx: A Multi-Centre, Single Arm Prospective Cohort Study

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

De-intensified radiotherapy to a dose of 60 Gy to the primary tumour and involved lymph nodes and 54 Gy to subclinical regions at risk in 30 fractions. Omission of level IB lymph node regions from the elective nodal volumes.

Chemotherapy will be administered as per standard of care, consisting of concurrent cisplatin (high-dose: 100mg/m2 IV every 3 weeks or low-dose: 40mg/m2 IV every week) or cetuximab (at the discretion of medical oncologist).
