RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Intensity-modulated radiation therapy delivers thin beams of radiation of different strengths directly to the tumor from many angles. This type of radiation therapy may reduce damage to the parotid (salivary) glands, prevent xerostomia (dry mouth), and improve quality of life. It is not yet known whether intensity-modulated radiation therapy is more effective than conventional radiation therapy in preventing xerostomia and improving quality of life in patients who have throat cancer.

PURPOSE: This randomized phase III trial is studying intensity-modulated radiation therapy to see how well it works compared to conventional radiation therapy in treating patients with oropharyngeal or hypopharyngeal cancer who are at risk of developing xerostomia caused by radiation therapy.

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Proportion of patients suffering xerostomia ≥ grade 2 by LENT/SOMA late toxicity scale at 1 year

Secondary Outcome Measures:
  • Degree of xerostomia by salivary flow at 1 year
  • Xerosomia-related quality of life by Modified Xerostomia questionnaire at 1 year
  • Quality of Life by EORTC QLQ C30 v.3.0 and QLQ-H&N35 questionnaires at 1 year
  • Local and regional tumor control by a quantitative description of sites of relapse at 1 year
  • Time to tumor progression at 1 year
  • Overall survival at 1 year
  • Acuteside effects of radiotherapy by NCI CTCAE scale v. 3.0 at 1 year
  • Late side effects of radiotherapy by NCI CTCAE scale v3.0, LENT SOMA and RTOG at 1 year

Estimated Enrollment: 84
Study Start Date: January 2004
Estimated Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Detailed Description:



  • 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.


  • 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.

PROJECTED ACCRUAL: A total of 84 patients (42 per treatment arm) will be accrued for this study.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • 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
