The standard treatment for non-anaplastic non-medullary thyroid cancer is radiation delivered through a liquid or capsules containing radioactive iodine. Some patients also undergo surgery. Yet sometimes the cancer persists.
In this study, researchers are evaluating a form of external radiation therapy called intensity-modulated radiation therapy (IMRT) for patients with non-anaplastic non-medullary thyroid cancers that persist despite radioactive iodine treatment and surgery, or for whom surgery is not an option. With IMRT, patients receive highly customized radiation beams of different intensities delivered from different angles to target cancerous tissue precisely, sparing nearby healthy tissue from damage.
