Could less radiation be just as good for lymphoma?

NCT ID NCT03681535

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times

Summary

This study is testing whether a lower dose of radiation (20 Gy instead of 30 Gy) can still control diffuse large B-cell lymphoma in patients who had a good response to chemotherapy. About 241 participants will receive the reduced radiation to see if it keeps the cancer from coming back while causing fewer side effects. The goal is to maintain high local control rates with less toxicity.

Active substance

radiation therapy

What this could lead to

If successful, this could mean that many lymphoma patients can receive a lower, safer dose of radiation without compromising cancer control.

What could go wrong

This is a mid-stage study with 241 participants, so results are not yet confirmed. Lower radiation might not control the cancer as well as the standard dose.
