Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. This trial is being done to determine if giving radiation therapy to patients who are being treated with immunotherapy and whose cancers are progressing (getting worse) can slow or stop the growth of their cancers. It may also help researchers determine if giving radiation therapy to one tumor can stimulate the immune system to attack other tumors in the body that are not targeted by the radiation therapy.","PRIMARY OBJECTIVE:\n\nI. To determine whether radiation therapy can convert overall response rates from progressive disease to stable or responsive disease as measured by Response Evaluation Criteria in Solid Tumors (RECIST) version (v.) 1.1.\n\nSECONDARY OBJECTIVES:\n\nI. To define overall response rate by immune-Modified Response Evaluation Criteria in Solid Tumors (iRECIST) criteria.\n\nII. To determine time to progression. III. To determine overall survival. IV. To determine local control in radiated lesion(s). V. To characterize the effect of distant radiation on unirradiated target lesions.\n\nVI. To describe the incidence of new metastatic lesions. VII. To determine treatment safety by Common Terminology Criteria for Adverse Events (CTCAE) v. 5.0.\n\nVIII. To describe time to new systemic therapy.\n\nEXPLORATORY OBJECTIVES:\n\nI.
