Anti-Leukemia Immune Responses After Irradiation of Extramedullary Tumors


Description

This clinical trial assesses how the immune system responds to leukemia tumors after low dose radiation delivered as part of standard of care. The information learned in this study may help them know if adding immunotherapy (a type of treatment that uses the immune system to fight cancer) can be helpful in future leukemia patients receiving radiation.PRIMARY OBJECTIVES: I. To identify changes in anti-leukemia immune responses after local radiotherapy to extramedullary sites. II. Develop an annotated biospecimen panel of extramedullary leukemia biopsies prior to and after radiotherapy to examine local immune responses using transcriptional profiling, immunofluorescence and single cell analyses. III. Define changes in the T cell receptor (TCR) clonotypes, functionality and inflammatory cytokine levels in peripheral blood leukocytes and serum. IV. Correlate changes in anti-tumor immune responses with clinic-pathological variables and patient outcomes. SECONDARY OBJECTIVES: I. To ass
