Radiation Therapy With or Without Cetuximab in Treating Patients With Stage III or Stage IV Cancer of the Oropharynx, Hypopharynx, or Larynx
Summary
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Monoclonal antibodies such as cetuximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known if radiation therapy is more effective with or without cetuximab for cancer of the oropharynx, hypopharynx, or larynx.
PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without cetuximab in treating patients who have stage III or stage IV cancer of the oropharynx, hypopharynx, or larynx.
Description
OBJECTIVES:
- Compare the rate of locoregional disease control maintained for 1 year in patients with advanced squamous cell carcinoma of the oropharynx, hypopharynx, or larynx treated with radiotherapy with or without concurrent cetuximab.
- Compare the response rates, progression-free survival and overall survival rates, and quality of life in patients treated with these regimens.
- Compare acute and late toxicity of these regimens in these patients.
- Determine tumor epidermal growth factor receptor levels in patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified by Karnofsky performance status (60-80% vs 90-100%), nodal stage (N0 vs N+), tumor stage (T1-3 vs T4), and radiotherapy schedule (concurrent boost vs once daily vs twice daily).
Patients are randomized to 1 of 2 treatment arms:
- Arm I: Patients undergo radiotherapy beginning on day 1. Patients are assigned to 1 of 3 radiotherapy groups:
- Group 1: Patients undergo concurrent boost radiotherapy comprised of radiotherapy once daily 5 days a week for 3.5 weeks followed by radiotherapy twice daily 5 days a week for 2.5 weeks.
- Group 2: Patients undergo radiotherapy once daily 5 days a week for 7 weeks.
- Group 3: Patients undergo radiotherapy twice daily 5 days a week for 6-6.5 weeks.
- Arm II: Patients receive a test dose of cetuximab IV over 10 minutes on day 1. Patients who do not experience grade 4 anaphylactic reaction receive a loading dose of cetuximab IV over 2 hours beginning 30 minutes after completion of test dose. Patients receive maintenance cetuximab IV over 1 hour on day 8. Maintenance cetuximab repeats every week for 7 courses. Beginning on day 8, patients undergo radiotherapy as in arm I concurrently with maintenance cetuximab. There must be an hour interval between the completion of cetuximab infusion and the start of any radiotherapy.
Patients with more than N1 neck disease at initial presentation undergo neck dissection 4-8 weeks after the completion of radiotherapy.
Quality of life is assessed before initiation of study therapy, at 8 weeks, and then every 4 months for 1 year.
Patients are followed at 8 weeks, every 4 months for 2 years, and then every 6 months for 3 years.
PROJECTED ACCRUAL: Approximately 416 patients (208 per arm) will be accrued for this study within approximately 5 years.

Medical and Biotech [MESH] Definitions
Chemotherapy, Adjuvant
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Head And Neck Neoplasms
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
Neck Dissection
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Neoadjuvant Therapy
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Rhabdomyosarcoma, Embryonal
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
