Study Summary

Spatially fractionated radiotherapy (SFRT or GRID) addresses some limitations of traditional stereotactic body radiation therapy by relying on beam collimation to create high-dose "peaks" and intervening low-dose "valleys" throughout the target volume. Standard palliative radiotherapy regimens provide limited durability of response, and there are challenges with delivery to large tumors or in previously irradiated fields. In this study, Proton GRID radiotherapy will be used to deliver three-fraction palliative radiotherapy to patients with tumors needing palliative radiation. The safety and efficacy of this approach will be assessed. It is hypothesized that GRID is highly effective, immunogenic, and associated with low rates of toxicity.
