Abstract

OBJECTIVE:

Gamma knife radiosurgery (GKRS) has emerged as an important therapeutic alternative for different intracranial lesions. We have reviewed our institution's first 1,000 cases of radiosurgeries.

MATERIALS AND METHODS:

We performed a retrospective review (2000-2013) of 1,017 radiosurgeries in 911 patients with various intracranial lesions including vestibular schwannoma (82), meningioma (136), metastatic brain tumors (298), astrocytoma (49), pituitary adenoma (92), arteriovenous malformation (85) and trigeminal neuralgia (169).

RESULTS:

GKRS in different intracranial lesions showed significant variations in outcome and complications. Overall, the local tumor growth control for benign and malignant tumors was 89 percent and 70 percent respectively. The rate of obliteration of arteriovenous malformation nidus was 79 percent. The complete and partial relief of pain in the patients with trigeminal neuralgia was 55.6 percent and 22.4 percent respectively.

CONCLUSION:

At recent follow-up, GKRS showed good control of different tumor growth, obliteration of AVM nidus and remission of trigeminal neuralgia pain, good overall and progression free survival rate, possible preservation of neurological functions, lesser number of complications, and improvement of quality of life. Therefore, GKRS is an important treatment option for patients with different benign intracranial tumors, AVM and trigeminal neuralgia. However, GKRS is not effective for recurrent malignant tumors in the brain.
