RecruitingRadiation therapyA Study of Radiation Therapy to Treat Solid Tumor Cancer That Has Spread to Soft TissueThe purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
