RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether radiation therapy is more effective with cisplatin or cetuximab in treating oropharyngeal cancer.
PURPOSE: This phase III trial is studying radiation therapy with cisplatin or cetuximab to see how well it works in treating patients with oropharyngeal cancer.
Phase III Trial of Radiotherapy Plus Cetuximab Versus Chemoradiotherapy in HPV-Associated Oropharynx Cancer
OUTLINE: This is a multicenter study. Patients are stratified according to T stage (T1-2 vs T 3-4), N stage (N0-2a vs N2b-3), Zubrod performance status (0 vs 1), and smoking history (≤ 10 pack-years vs> 10 pack-years). Patients are randomized to 1 of 2 treatment arms.
Tumor tissue and blood samples are collected at baseline and may also be collected at 3- and 6-month follow-up visits for correlative studies.
Patients may complete quality-of-life questionnaires and risk factors for head and neck cancer surveys at baseline, periodically during study, and at follow-up for 1 year.
After completion of study therapy, patients are followed up at 1-3 months, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
