Resumen
Fecha de inicio: 1 de enero de 2004
Fecha en la que se inscribió al primer participante.OBJECTIVES: Primary * Compare the proportion of patients with oropharyngeal or hypopharyngeal cancer with xerostomia of ≥ grade 2 at one year after treatment with parotid-sparing intensity-modulated radiotherapy vs conventional radiotherapy. Secondary * Compare the degree of xerostomia by quantitative measurements of stimulated and unstimulated salivary flow in patients treated with these regimens. * Compare quality of life in patients treated with these regimens. * Compare local and regional tumor control, time to tumor progression, and overall survival of patients treated with these regimens. * Compare acute and late side effects of these regimens in these patients. OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to participating center and site of disease (oropharynx vs hypopharynx). Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients undergo parotid-sparing intensity-modulated radiotherapy once daily, 5 days a week, for 6 weeks. * Arm II: Patients undergo conventional radiotherapy once daily, 5 days a week, for 6 weeks. Salivary flow measurements are performed at baseline, at week 4 during radiotherapy, and then at 2 weeks and at 3, 6, 12, and 24 months after the completion of radiotherapy. Quality of life is assessed at baseline, at 2 weeks, and then at 3, 6, 12, 18, and 24 months after the completion of radiotherapy. Patients are followed monthly for 1 year, every 2 months for 1 year, and then every 6 months for 3 years. Peer Reviewed and Funded or Endorsed by Cancer Research UK PROJECTED ACCRUAL: A total of 84 patients (42 per treatment arm) will be accrued for this study.

DISEASE CHARACTERISTICS: * Histologically confirmed oropharyngeal or hypopharyngeal cancer * Squamous cell or undifferentiated carcinoma * Stage T1-4, N0-3, M0 disease * Primary tumor requiring radical radiotherapy with parallel opposed lateral fields and bilateral cervical lymph node irradiation * Radiotherapy is either the primary therapy or post-operative (adjuvant irradiation) treatment * High-risk for radiation-induced xerostomia with conventional radiotherapy due to irradiation of the majority of both parotid glands\* NOTE: \*Estimated mean dose to both parotid glands is greater than 24 Gy by conventional radiotherapy * No bilateral N3 nodal disease * No huge primary tumor (exceeding 10 cm in diameter) * No contralateral lymphadenopathy adjacent to or involving contralateral parotid gland making parotid sparing impossible * No tumor at the base of the tongue where sparing of contralateral parapharyngeal space is contraindicated PATIENT CHARACTERISTICS: Age * Not specified Performance status * WHO 0-1 Life expectancy * Not specified Hematopoietic * Not specified Hepatic * Not specified Renal * Not specified Other * Able to undergo quality of life and salivary flow measurements (dependent on cognitive aptitude and long availability) * Able to complete self-assessed quality of life questionnaire * No prior or concurrent illness that would preclude study participation * No pre-existing salivary gland pathology interfering with saliva production * No other prior malignancy except nonmelanoma skin cancer PRIOR CONCURRENT THERAPY: Biologic therapy * Not specified Chemotherapy * Prior neoadjuvant chemotherapy allowed * No concurrent chemotherapy Endocrine therapy * Not specified Radiotherapy * See Disease Characteristics * No prior radiotherapy to the head and neck region * No concurrent brachytherapy Surgery * See Disease Characteristics Other * No concurrent prophylactic amifostine or pilocarpine
