A Phase II Study of PET Adapted Therapy and Non-invasive Monitoring for Previously Untreated Limited Stage Diffuse Large B Cell Lymphoma
University of Rochester
Summary
The overarching goals of this study are to measure levels of circulating tumor DNA (ctDNA) in patients with early stage diffuse large B cell lymphoma (DLBCL), to assess the change in ctDNA during treatment in order to prospectively identify markers of treatment failure, and to use ctDNA as a future tool for response adapted therapy.
Description
The long-term objective of this proposal is to determine the correlation between FDG-PET and MRD, as measured by ctDNA in patients with early stage DLBLC. Patients will be treated with standard chemoimmunotherapy and radiation based on the recently completed SWOG S1001 study, however no radioimmunotherapy will be used (NCT01359592). Response to treatment will be determined by contemporary Deauville criteria. Assessment of ctDNA (non-invasive disease monitoring) will be determined at diagnosis and will continue at pre-defined specific time points after therapy is complete.
