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.
