RATIONALE: Drugs used in chemotherapy, such as cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Monoclonal antibodies, such as panitumumab, 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 chemotherapy given together with radiation therapy is more effective with or without panitumumab in treating patients with advanced cancer of the hypopharynx, oropharynx, larynx, or oral cavity.
PURPOSE: This randomized phase III trial is studying chemotherapy given together with radiation therapy to see how well it works compared with chemotherapy and radiation therapy given together with panitumumab in treating patients who have undergone surgery for advanced hypopharyngeal cancer, oropharyngeal cancer, laryngeal cancer, or oral cavity cancer at high risk of recurrence.
- To determine if the addition of concurrently administered panitumumab to standard adjuvant chemoradiation, with 1 of 2 cisplatin-based regimens, significantly prolongs disease-free survival of patients with macroscopically completely resected, advanced squamous cell carcinoma of the hypopharynx, oropharynx, larynx, or oral cavity at high risk of recurrence.
- To determine if the pre-surgery dose of panitumumab will alter the RNA expression of several genes and that these changes will provide additional prognostic information that can be used in future patient management. (Exploratory)
- Measure the differences in RNA expression by RNA microarray and the results analyzed to create a gene expression classifier that will be checked for outcome prediction by association with disease free survival and down regulation of the glucose metabolism as measured by FDG-PET. (Exploratory)
- To create a European biobank of biological samples which can be used for future research projects in this disease. (Exploratory)
- To predict radiation-induced normal tissue toxicity based on in vitro lymphocyte apoptosis test and SNPs analysis. (Exploratory)
- To assess the impact of radiation-induced side effects (swallowing dysfunction and xerostomia) on patient's quality of life.
OUTLINE: This is a multicenter study. Patients are stratified by treatment center, radiotherapy technique (3D-CRT vs IMRT), chemotherapy regimen (European Organization for Research and Treatment of Cancer [EORTC]) vs Arbeitsgemeinschaft Radiology Oncology [ARO] schedule), tumor location (larynx vs oropharynx vs hypopharynx vs oral cavity), pN-stage (pN0-2 vs pN3), pT-stage (pT1-2 vs pT3-4), margin/extracapsular extension (ECE) status (ECE+ and margin < 5 mm vs ECE- and margin < 5 mm vs ECE+ and margin > 5 mm), biological pre-study participation (yes vs no), p16 status (positive vs negative vs indeterminable). Patients are randomized to 1 of 2 treatment arms.
- Arm I (chemoradiotherapy): Within 4-8 weeks of surgery, patients undergo 3D-conformal or intensity-modulated radiotherapy once daily 5 days a week in weeks 1-7. Patients also receive concurrent chemotherapy comprising either cisplatin IV over 1-2 hours on days 1, 22, and 43 (EORTC schedule) OR cisplatin IV over 1-2 hours and fluorouracil IV over 24 hours on days 1-5 and 29-33 (ARO schedule), in the absence of disease progression or unacceptable toxicity.
- Arm II (chemoradiotherapy plus panitumumab): Within 4-8 weeks of surgery, patients undergo 3D-conformal or intensity-modulated radiotherapy and receive concurrent chemotherapy (EORTC schedule or ARO schedule) as in arm I. Patients also receive panitumumab IV over 1 hour on days 1, 8, 15, 22, 29, 36, and 43.
Blood samples are collected periodically for biomarker correlative studies and translational research. Patients complete quality-of-life EORTC questionnaires QLQ-C30, QLQ-HN35, and PSS-HN periodically.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
