Reduced Dose Radiation Therapy for Follicular Lymphoma
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the use of a very low dose of radiation therapy (VLDRT) to treat follicular lymphoma and marginal zone lymphoma. The goal is to determine if VLDRT can effectively target cancer and prevent new growths while causing fewer side effects than the standard radiation dose. Individuals diagnosed with stage I or II follicular or marginal zone lymphoma, who have not yet received any lymphoma-directed therapy, might be suitable for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking advancements in cancer treatment.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it does exclude patients who are planned to receive other systemic therapy (like oral steroids) for their lymphoma. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that very low dose radiation therapy (VLDRT) is generally well-tolerated by patients with certain types of lymphoma. Studies indicate that VLDRT, which uses a total of 4 Gy of radiation, has a high success rate. For example, one study found a 90% overall response rate in patients with slow-growing B-cell lymphomas. Additionally, VLDRT demonstrated excellent results in specific cases, such as lung MALT lymphoma, where patients achieved complete local control without needing further treatment.
Compared to the standard radiation dose of 24 Gy, VLDRT may cause fewer side effects due to its lower radiation use. This reduction can potentially lead to fewer short- and long-term side effects, making it a safer option for some patients. Overall, evidence suggests that VLDRT is a promising and safer alternative, though more research is needed to fully understand its long-term safety.12345Why are researchers excited about this study treatment for lymphoma?
Researchers are excited about the reduced dose radiation therapy for follicular lymphoma because it offers a potentially safer and more convenient option for patients. Unlike the standard treatment, which involves a total of 24 Gy over several weeks, this approach uses a very low dose of only 4 Gy delivered in just 1-2 days. This significant reduction in radiation exposure could minimize side effects and improve the patient's quality of life while still effectively targeting the cancer. Additionally, the shorter treatment duration means less time spent in the hospital, which is a huge advantage for patients.
What evidence suggests that this trial's treatments could be effective for follicular lymphoma?
Research has shown that very low dose radiation therapy (VLDRT) holds promise for treating follicular lymphoma. In this trial, participants will receive either a very low dose or a standard dose of radiation. Studies indicate that administering two doses of VLDRT at 2 Gy results in a 90% overall response rate in various slow-growing B-cell lymphomas. This suggests that most patients experience a significant reduction in cancer with VLDRT. Additionally, VLDRT has proven effective for grade 3A follicular lymphoma, offering a shorter treatment duration and potentially fewer side effects. Overall, VLDRT appears to be a strong option for effectively managing these lymphomas.14678

What Are the Treatments Tested in This Trial?
Interventions
- Very low dose Radiation Therapy
Trial Overview
The study is testing the effectiveness of a very low dose of radiation therapy (VLDRT) compared to the standard dose in treating cancer and preventing new spots of lymphoma. It's designed to see if VLDRT can be as effective but cause fewer side effects.

Active Control
Patients will receive a total of 24 Gy in 12 fractions comprehensively to all initially involved sites of disease over 12 consecutive business days. At 12 weeks (+/- 4 weeks) post VLDRT, the patient will undergo repeat imaging and clinical evaluation.
