Brief summary
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy in treating patients who have stage II or stage III oropharyngeal cancer.
Detailed description
OBJECTIVES: * Assess target coverage and major salivary gland sparing in patients with stage II or III oropharyngeal cancer treated with intensity-modulated radiotherapy. * Determine the nature and prevalence of acute and late side effects of this treatment in these patients. * Determine the rate and pattern of locoregional tumor recurrence in these patients after this treatment. OUTLINE: This is a multicenter study. Patients receive 3-D conformal radiotherapy and/or intensity-modulated radiotherapy daily 5 days a week for 6 weeks, in an effort to spare major salivary glands. Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: Approximately 57-64 patients will be accrued for this study over 27 months.
