Predictive factors of tumor control and survival after radiosurgery for local failures of nasopharyngeal carcinoma

Conclusion: Important factors that predicted tumor control and survival after radiosurgery were identified. Patients with good prognostic score should be treated by radiosurgery in view of the excellent results. Patients with intermediate prognostic score may also be treated by radiosurgery but those with poor prognostic score should receive other salvage treatments.
