Study Details

Study Description

Brief Summary

The purpose of the study is to determine if it is feasible to use magnetic resonance imaging (MRI) to adjust a portion of radiation therapy for patients with head and neck squamous cell carcinoma . The technique under study will be used to personalize the study treatment based on response, keeping all treatments within standard of care guidelines.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Adaptive Radiotherapy treatment

Patients will undergo MR-guided adaptive radiotherapy boost for head/neck squamous cell carcinomas. A base conventional IMRT plan of 46-50Gy in 2 Gy to gross disease in the primary/nodes and 41.4-45 Gy in 1.8 Gy to the elective nodes per fraction will be utilized. The MR simulation will be utilized for boost treatment planning.Patients will receive their 6th fraction of the week on the ViewRay treating the gross disease until completion of the base plan to 20 Gy in 2Gy daily fractions (10 fractions). Each MRgART treatment will be recontoured/replanned by the treating head/neck radiation oncologist as deemed clinically or dosimetrically necessary.

Radiation: Intensity-modulated radiotherapy
All patients will be treated with intensity-modulated radiotherapy (IMRT) plans.
Other Names:
  • IMRT
  • Other: Magnetic Resonance Guidance
    All patients will undergo combined CT and MR simulation and will be treated with a sequential-boost technique.
    Other Names:
  • View Ray
  • Outcome Measures

    Primary Outcome Measures

    1. Improvement in Mean OAR Dose Reduction [Up to 15 months]

      Feasibility of MR adaptive boost technique, as defined as achieving a reduction of mean OAR (parotids, submandibular glands, pharynx, oral cavity, tubarial glands, larynx, esophagus, and thyroid) doses greater than 7.5% compared to unadapted CT based plan. If 18 of 25 patients are meet the mean OAR criteria the approach will be considered feasible.

    Secondary Outcome Measures

    1. Percentage of patients achieving a complete anatomic response [Up to 15 months]

      Percentage of patients achieving a complete anatomic response by CT Neck and Chest and/or PET/CT will be tabulated. The 95% CI by the exact binomial distribution will be reported.

    2. Percentage of patients achieving a complete metabolic response [Up to 15 months]

      Percentage of patients achieving a complete metabolic response by CT Neck and Chest and/or PET/CT will be tabulated. The 95% CI by the exact binomial distribution will be reported.

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • Provision of signed and dated informed consent form

    • Stated willingness to comply with all study procedures and availability for the duration of the study

    • ECOG performance status of 0, 1

    • Patients with histologically or cytologically confirmed squamous cell carcinoma of the oral cavity, oropharynx, nasopharynx, hypopharynx, larynx, or unknown primary in the neck.

    • Patients with measurable disease, either at primary site or neck per RECIST 1.1.

    • For patients planned to receive chemotherapy, adequate hematologic, hepatic and renal function as outlined in protocol.

    • Patients who had undergone definitive surgery for the index cancer.

    • Patients with distant metastatic disease

    • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements.

    • Unable to undergo MRIs or has contraindications to undergoing MRIs (pacemaker, neural stimulator, MR-incompatible metal, etc.
