PURPOSE: There is an unmet need for new treatments for many central nervous system tumors. An expanding body of research supports the use of laser interstitial thermal therapy (LITT) in the treatment of gliomas, recurrent brain metastases, and radiation necrosis. METHODS: In this review, we highlight emerging indications for LITT, including its use adjacent to eloquent structures, in the posterior fossa, and for meningioma and tumors of the vertebral column. We conclude by providing an overview of current research into post-LITT response assessment and adjunctive therapies. RESULTS: Evidence has continued to accumulate regarding the safety of LITT in locations as varied as the motor cortex, posterior fossa, and vertebral column, as well as for novel pathologies such as meningioma. Regardless of disease histology, most patients leave the hospital within 12-48 h of LITT and can rapidly return to systemic and radiation therapies. Emerging data has allowed for a characterization of post-LITT imaging findings, and receipt of LITT should not preclude subsequent clinical trial enrollment, especially as hyperthermia modulates blood-brain barrier permeability and may synergize with immunotherapies. CONCLUSION: As LITT is incorporated into neurosurgical oncology practice, novel use cases will continue to emerge. Given that laser ablation is associated with shortened length of stay and decreased debility relative to open resection, development of radiographic response assessment criteria for LITT-treated lesions is urgently needed so that patients may more rapidly receive definitive management or proceed to clinical trial enrollment. Prospective evaluation of LITT and adjunctive combination therapies is ongoing.
