Many Non-Hodgkin’s Lymphoma Patients Can Skip Radiation, Suggests Study Led by UArizona Researcher

Tuesday, December 10, 2019

Results from a SWOG Cancer Research Network study, led by Daniel Persky, MD, found many patients with the most common type of non-Hodgkin’s lymphoma can skip radiation treatment, reducing both costs and the time to heal from treatment.

A recent study led by a University of Arizona Cancer Center researcher suggests that many non-Hodgkin’s lymphoma patients can skip radiation in favor of a simpler course of treatment.

Daniel Persky, MD, served as the lead investigator for the study administered by the SWOG Cancer Research Network (a clinical trials network funded by the National Cancer Institute). Results were presented Dec. 8 at the 61st American Society of Hematology (ASH) Annual Meeting in Orlando, Fla.

The study found U.S. patients diagnosed with the most common subtype of non-Hodgkin’s lymphoma, diffuse large B-cell lymphoma (DLBCL), can safely skip radiation treatment after a clear positron emission tomography (PET) scan.

Dr. Persky is associate director of clinical investigations and director, Clinical Trial Office – Tucson, at the UArizona Cancer Center. He specializes in hematology/oncology, particularly in lymphoid malignancies, such as lymphoma and CLL. In addition, he serves as an associate professor of medicine at the UArizona College of Medicine – Tucson.
