Reduced Dose Radiotherapy for the Treatment of Indolent Non-Hodgkin Lymphoma (NCT06386315)
MC230808 Reduced Dose Hypofractionated Radiotherapy (3Gy x 3 Fractions) for Indolent Non-Hodgkin Lymphoma (POSEIDON): A Multisite Phase 2 Randomized Trial
🩺 Plain-English Summary (8th-Grade Level)
This phase II trial compares the safety, side effects and effectiveness of reduced dose radiation therapy to standard of care dose radiation in treating patients with indolent non-Hodgkin lymphoma. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Standard of care radiation treatment for indolent non-Hodgkin lymphoma is usually delivered in 12 treatments. Studies have shown indolent lymphoma to be sensitive to radiation treatment, however, larger doses have higher rates of toxicities. A reduced radiation dose may be safe, tolerable and/or effective compared to standard of care radiation dose in treating patients with indolent non-Hodgkin lymphoma.
