Detailed Summary

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.
