Condition Intervention Phase
Head and Neck Cancer
Radiation: IMRT

Primary Purpose: Treatment
Official Title: A Feasibility Study of Adaptive Intensity-Modulated Radiation Therapy in the Definitive Treatment of Head-and-Neck Cancer

Further study details as provided by Washington University School of Medicine:

Primary Outcome Measures:
  • Feasibility of adaptive radiation therapy in the definitive treatment (MLC-based IMRT or helical tomotherapy) [ Time Frame: 7 weeks ]
    Feasibility is determined by employing weekly 3D onboard imaging for plan re-evaluation and initiation of an adaptive process if the original PTV and/or normal structure goals are compromised.

Secondary Outcome Measures:
  • Measure additional time required by physician and ancillary staff for the process of adaptive IMRT [ Time Frame: 7 weeks ]
    Recording on a weekly basis the actual time required for repeat CT imaging, plan re-evaluation, replanning, and repeat physics QA.

  • Identify a subset of patients in whom adaptive IMRT would be recommended [ Time Frame: 7 weeks ]
  • Measure acute and late toxicity [ Time Frame: Until patient death ]
  • Local, regional, and distant recurrence [ Time Frame: Until recurrence ]

Enrollment: 5
Study Start Date: January 2007
Study Completion Date: January 2008
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IMRT
External beam radiation with 6 MV photons will be delivered in 200 cGy daily fractions, 35 fractions over 7 weeks for a total dose of 7000 cGy.
Radiation: IMRT

Detailed Description:
In this study, we will plan additional measurements of the position of the patient's organs weekly during radiation treatment. We will analyze these measurements in order to evaluate whether we need to adjust our treatment procedures for the remainder of the treatments. We might adjust the dose of radiation received to specific organs in order to try to minimize the amount of radiation the healthy tissue receives.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age >= 18
  • Karnofsky Performance Status of >= 60
  • New diagnosis of head-and-neck cancer, all subsites included (i.e. nasopharynx, oropharynx, oral cavity, hypopharynx, larynx.)
  • All stages with measurable gross disease (>= 1.0 cm) by CT imaging
  • Pathologic confirmation of squamous cell carcinoma by biopsy or cytology
  • Signed study-specific consent form
  • Sequential or concurrent chemotherapy is allowed but not mandated. (no chemotherapy is allowed if patient is judged not to be a candidate for chemotherapy by the medical oncologist)

Exclusion Criteria

  • Age < 18
  • Karnofsky Performance Status < 60
  • Radiographic or pathologic evidence of distant metastatic disease (i.e. other than cervical lymph nodes)
  • Prior radiation therapy to the head-and-neck region
