Which Patients Benefit from Radiation Therapy in Diffuse Large B-Cell Lymphoma in 2023? Recent Evidence and Future Developments
The role of RT in DLBCL is changing. Recent randomized studies have challenged the role of RT in the primary treatment of DLBCL but they included selected patient populations, making application of results in routine clinical practice difficult. In addition, some of the studies based on imaging-response were not randomized and are being promoted as adequate evidence to omit RT, leading to further confusion and variation in practice. On the other hand, RT is increasingly being used in salvage treatment programs for DLBCL including CAR-T cellular therapy. The evidence in this context is mostly retrospective and is heterogeneous as the field is moving fast and prospective studies have just started. Radiation oncologists, particularly community oncologists need to keep up-to-date with new data and the changing role of RT to be able to work collaboratively with medical oncologists/hematologists and also with patients, guiding them to make better informed decisions. This activity discusses recent evidence and how it can be applied in routine clinical practice with emphasis on patient selection to maximize benefit and reduce toxicity with plenty of clinical examples.

Full Panel
This activity is available from February 20, 2024, through 11:59 p.m. Eastern time on February 19, 2026.
This activity was originally recorded at the 2023 ASTRO Annual Meeting.
Target Audience
The activity is designed to meet the interests of medical oncologists, radiation oncologists, nurses, radiation dosimetrists, radiation therapists, residents, and hematologists.
Learning Objectives
Upon completion of this activity, participants should be able to:
- Determine which patients benefit from consolidation RT for the primary treatment of DLBCL and discuss the evidence with hematologists and patients.
- Differentiate between cases with incomplete response to chemotherapy who can be successfully treated with RT and those who would be better treated with salvage systemic therapy.
- Assess patient and disease factors to select patients for bridging RT before CAR-T therapy and explain the selection to hematologists and patients.
