Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
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.
