ASTRO/ILROG Joint Activity: The Comeback of RT – Radiation Therapy is Back in the Frontline of Managing Hodgkin and Indolent Lymphomas

Given the rarity of lymphomas, many clinicians are not using radiation therapy appropriately in the frontline setting. Even when it is used, the clinician may not have had adequate experience in treating lymphomas, as a paltry 8 cases are required to meet minimum competency during residency training. As a result, educational sessions such as these are a critical way for clinicians to stay up to date on literature as well as learn new and emerging ways to treat lymphomas with radiation therapy.
In the past decade, the role of radiation therapy in lymphomas has shifted significantly. While initially there appeared to be data supporting a decreased need for RT in the frontline settings for non-Hodgkin and Hodgkin lymphomas, recent data showing unforeseen toxicities from chemotherapy, as well as changing approaches to using radiation therapy in lymphomas have solidified that radiation therapy is more important than ever in the frontline setting.

Topics:

  1. Updated and Recent Studies that Established the Necessity of RT in Early-Stage Hodgkin Lymphoma
    George Mikhaeel, MD, MBBS
  2. When, How and Why Should We Use Very Low Dose RT in Indolent Lymphomas?
    Brandon S. Imber, MD, MS
  3. Short and Long-Term Chemotherapy Toxicity Concerns in Lymphomas
    Joanna C. Yang, MD, MPH
  4. Closing Comments
    Joachim Yahalom, MD, FASTRO

This activity is available from June 9, 2026, through 11:59 p.m. Eastern time on June 8, 2028.
