Improved survival using intensity‐modulated radiation therapy in head and neck cancers: A SEER‐Medicare analysis

Intensity‐modulated radiation therapy (IMRT) is a technologically advanced, and more expensive, method of delivering radiation therapy with a goal of minimizing toxicity. It has been widely adopted for head and neck cancers; however, its comparative impact on cancer control and survival remains unknown. The goal of this analysis was to compare the cause‐specific survival (CSS) for patients with head and neck cancers treated with IMRT versus non‐IMRT from 1999 to 2007.
