Testing proton beam radiation therapy for early-stage Hodgkin lymphoma

This trial is testing proton beam therapy, a specialized type of radiation treatment designed to target cancer while reducing damage to healthy tissues around it. The study compares proton beam therapy to standard radiation therapy in people with early-stage Hodgkin lymphoma who have already completed chemotherapy. Researchers want to see if proton beam therapy can be just as effective at curing the cancer while causing fewer serious side effects over time, such as heart problems, lung damage, or second cancers.

Standard radiation therapy for Hodgkin lymphoma works well but can damage healthy organs nearby, leading to long-term complications years later. This medication targets tumors more precisely, potentially sparing the heart, lungs, and other organs from unnecessary radiation exposure.
