Stereotactic Boost for Oropharyngeal Squamous Cell Carcinoma

Overview

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention (in this case, the stereotactic radiation boost). Phase I studies also try to define the appropriate dose of the investigational intervention to use for further studies. "Investigational" means that the stereotactic radiation treatment is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved a stereotactic radiation boost for your type of cancer. In this research study, the investigators are looking for the highest dose of the stereotactic radiation boost that can be given safely. Because the stereotactic radiation boost is so precise, the investigators are testing whether it can be used to increase the dose to the primary tumor without significantly increasing the side effects you experience; the goal is to improve the likelihood of successfully treating the tumor.

After confirming that you are eligible for this study and your willingness to participate in it, we will perform a radiation treatment stimulation, or "mapping session," within the next two weeks. You may or may not receive intravenous contrast during the process, which allows your physician to better see the blood vessels in your neck. You will be placed in a mask during this process to help keep you in the same place during each treatment. All of this is part of standard radiation treatment. Approximately 14 days later, you will start radiation treatment to your primary tumor site and to your lymph nodes and chemotherapy in the same week. The chemotherapy will continue to be given one time per week during each week of treatment. You will receive radiation treatment 5 days a week for seven weeks. One day each during the first and second weeks of treatment, instead of the typical radiation dose, you will receive a dose of the stereotactic radiation boost to the site of the primary tumor (total of 2 doses of stereotactic radiotherapy). Because we are looking for the highest dose of the stereotactic radiation boost that can be administered safely without severe or unmanageable side effects, not everyone who participates in this research study will receive the same dose of the stereotactic radiation boost. The dose you get will depend on the number of participants who have been enrolled in the study before you and how well they have tolerated their doses. We are testing 3 different dose levels for the stereotactic radiation boost; your dose will be one of those 3 doses. The chemotherapy will be given one time per week, each week, for the duration of the radiation treatment (7 weeks). The chemotherapy is delivered through intravenous fluids that run through a vein in your arm. This is the same chemotherapy that you would receive if you were not participating in the study. You will be seen by your radiation oncologist at least once every week during treatment. After the final dose of radiation treatment all subsequent follow-up visits and tests are performed in accordance with standard cancer care. You will see your radiation oncologist, with or without the medical oncologist, at the following time intervals: 1 week after treatment ends, 1 month after treatment ends, 2 months after treatment ends, and then every 3 months for two years. You will undergo a PET-CT scan and neck CT scan at the time of the 3 month appointment. You will be on the study treatment for about 7 weeks and your progress will be followed as part of the study for 2 years after treatment ends.
