Summary

The goal of this clinical research study is to compare the side effects of 2 radiation treatments for head and neck cancer. The 2 treatments are intensity modulated photon therapy (IMRT) and intensity modulated proton therapy (IMPT). Participants will also receive chemotherapy along with radiation therapy.

IMPT is designed to use beams of proton particles to send radiation to the tumor. IMRT is designed to use beams of photon therapy to send radiation to the tumor. Both of these types of radiation treatment may give a full dose of radiation treatment to the tumor while not damaging as much of the healthy tissue around it.

This is an investigational study. IMRT and IMPT are delivered using FDA-approved and commercially available methods. Comparing them is investigational.

Up to 360 participants will be enrolled in this study. Up to 250 patients will take part at MD Anderson.

Description

Baseline Visit:

If you are found to be eligible to take part in this study, you will have a baseline visit. The following tests and procedures will be performed:

  • You will be asked about your diet and if you have had recent weight loss.
  • You will have a dental exam.
  • Your swallowing function will be tested with a special type of x-ray called a modified barium swallow (MBS). During the test, you will eat and drink foods and liquids mixed with a "contrast" chemical called barium that will make your throat more visible in the x-rays. A special x-ray tube will be connected to a television screen to allow the doctor to watch the foods and liquids pass from your mouth and down your throat. As part of this exam, each time you will fill out a questionnaire about swallowing that should take about 5 minutes to complete.
  • You will have a video-strobe procedure or laryngoscopy to allow the doctor to look at your vocal cords. To perform a video-strobe procedure, a small camera will be inserted into the throat through your nose or mouth. You will be awake for this procedure and the study staff will give you the option of receiving a numbing spray for your nose and/or throat. A laryngoscopy is a standard procedure in which a tube with a lighted camera is inserted through your mouth and into your throat.
  • Photos of the inside of your mouth will be taken to check for mouth sores.
  • You will fill out questionnaires about your quality of life, work status, medical history, smoking status, and any symptoms you may have. Completing these questionnaires should take about 10-15 minutes. An email address will be collected for the transmitting questionnaires. An email address will be collected for the transmitting questionnaires.
  • Saliva will be collected and your jaw will be measured at this visit, at the end of your treatment, and also during follow up for 2 years. You should be fasting for a minimum of 60 minutes and instructions regarding the collection will be given.

Study Groups:

You will go through the standard radiation treatment planning procedure, called the marking session. After the marking session, a standard IMRT plan and an IMPT plan will be made. If the radiation doctor thinks that both the plans are acceptable, you will be randomly assigned (as a flip of a coin) to 1 of 2 study groups:

If you are in Group 1, you will receive IMRT.

If you are in Group 2, you will receive IMPT.

If you are assigned to Group 1 but do not receive the IMRT treatment, you will be moved to Group 4. You will then have follow-up only to be asked about the status of the disease and how you are doing, as explained below.

If you are assigned to Group 2 but do not receive the IMPT treatment, you will be moved to Group 3. You will then have follow-up only to be asked about the status of the disease and how you are doing.

Study Therapy Administration:

You will receive radiation therapy 1 time each day, 5 days a week (Monday through Friday) for up to 33 treatments (about 6 weeks).

You will receive chemotherapy while you are receiving radiation therapy. You will be asked to sign a separate treatment consent form for these drugs with a full description of how they are given and the risks they may cause. The drugs, schedule, and doses will be your doctor's decision.

Study Visits:

Every week while you are receiving radiation therapy:

  • Any updates to your medical history will be recorded.
  • You will have a physical exam, including measurement of your vital signs and weight.
  • Blood (about 1-2 tablespoons) will be drawn for routine tests.
  • You will fill out the same questionnaires as before.
  • At Week 3, photos of the inside of your mouth will be taken to check for mouth sores.

Length of Treatment:

You may continue receiving radiation therapy for up to 6 weeks. You will no longer be able to receive the study therapy if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over after you complete all the follow-up visits.

You can decide to stop taking part in this study and the study doctor will tell you how to stop safely. It is important to tell the study doctor if you are thinking about stopping so any side effects from the treatment can be looked at by your doctor. Another reason to tell your doctor that you are thinking about stopping is to discuss what follow-up care and testing could be most helpful for you.

End-of-Treatment Visit:

After you finish radiation therapy (at Week 7):

  • You will fill out the same questionnaires as before.
  • You will have a dental exam, including jaw measurements and collection of saliva.
  • Photos of the inside of your mouth will be taken to check for mouth sores.

Follow-Up:

At 8-12 weeks after finishing radiation therapy:

  • You will have a dental exam, including jaw measurements and collection of saliva.
  • Photos of the inside of your mouth will be taken to check for mouth sores.
  • If the doctor thinks it is needed, you will have a CT scan or PET/CT scan to check the status of the disease.

During Follow-Up Months 6, 12, and 24:

  • You will have an MBS exam to test your swallowing function.
  • You will fill out the same questionnaires as before.
  • Saliva and jaw measurements will be collected.
  • Photos of the inside of your mouth will be taken to check for mouth sores.
  • You will have a laryngoscopy or video-strobe procedure to allow the doctor to look at your vocal cords.
  • You will have a CT or PET scan.

During Follow-Up Months 9, 16, and 20:

  • Saliva and jaw measurements will be collected.
  • You will fill out the same questionnaires as before.
  • You will have a CT or PET scan.

Every 6 months during Follow-Up Month 30 through Follow-Up Year 5:

  • You will fill out the same questionnaires as before.
  • You will have a CT or PET scan.

After you finish radiation therapy and during the 8-12 weeks while you are recovering from treatment, you will be provided with a questionnaire, by email or in paper form, that asks about any side effects you may have had. You will fill out this form every 2 weeks during this time period. Filling out the form should take about 10-15 minutes.

Filling out these forms does not take the place of your regularly scheduled follow-up visits. If you have side effects, you should also tell the study staff.

If the doctor thinks it is needed during follow-up, you will have a tumor biopsy for tumor marker testing.
