Chemotherapy and Radiation Therapy With or Without 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

• Status: Withdrawn
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

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.
