Abstract:
Locoregional failure after radiation therapy is a significant problem in the management of head and neck cancer. Reirradiation is rarely used in conventional radiation therapy because of concerns about treatment-related toxicity and lack of efficacy. However, stereotactic radiotherapy, which was made possible by the advancement in therapeutic devices enables reirradiation. The CyberKnife system is one of the best devices for stereotactic radiotherapy. We discuss salvage treatment, including reirradiation using the CyberKnife system, in patients with locally recurrent head and neck cancer patients.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
