Spine Stereotactic Radiosurgery Provides Long-Term Local Control and Overall Survival for Benign Intradural Tumors.
Background and objectives: The role of radiosurgery in the treatment of benign intracranial tumors is well established. However, there are limited long-term follow-up studies on outcomes after stereotactic radiosurgery (SRS) for benign intradural spinal tumors. In this article, we report a large single-institution experience in using SRS to treat patients with benign intradural tumors of the spine.
Methods: Overall, 184 patients (55% female) and 207 benign intradural tumors were treated. The median patient age was 52 years (range: 19-93). Tumor histology included schwannoma (38%), meningioma (15%), neurofibroma (21%), hemangioma (9%), hemangioblastoma (8%), hemangiopericytoma (5%), and paraganglioma (4%). Thirty-four (16%) lesions underwent resection before radiosurgery. Twenty-three (11%) lesions were NF1-mutated. The median single-fraction margin dose was 14 Gy (range: 11-20), and the median multifraction margin dose was 21 Gy (range: 15-30).
Results: The median follow-up was 63 months (range: 1-258). At last follow-up, tumors volumetrically regressed (15%), remained stable (77%), or locally progressed (8%, median: 20 months [range: 3-161]) after SRS. The 1-, 5-, and 10-year local control rates were 97%, 92%, and 90%, respectively. On multivariable analysis, the absence of the NF1 mutation (P = .004, hazard ratio: 0.23, 95% CI: 0.08-0.63) and single-fraction SRS (P = .007, hazard ratio: 0.24, 95% CI: 0.08-0.68) correlated with improved local control. The median overall survival was 251 months (range: 1-258), and 1-, 5-, and 10-year overall survival rates were 95%, 85%, and 70%, respectively. For patients with pre-existing symptoms, tumor-associated pain and neurological deficits were noted to improve or remain stable in 85% and 87% of cases, respectively. Adverse radiation effects included delayed myelopathy (1%), acute pain flare (9%), dermatitis (0.5%), dysphagia (0.5%), and dysphonia (0.5%).
Conclusion: With long-term follow-up, spine radiosurgery is a safe and effective treatment for benign intradural tumors. In carefully selected patients, even with an NF1 mutation, SRS is associated with a high likelihood of local tumor control.
