Abstract
Please see the full-text version of this guideline https://www.cns.org/guidelines/guidelinestreatment- adults-metastatic-brain-tumors/chapter-2) for the target population of each recommendation listed below. SURGERY FOR METASTATIC BRAIN TUMORS AT NEWDIAGNOSIS QUESTION: Should patients with newly diagnosed metastatic brain tumors undergo surgery, stereotactic radiosurgery (SRS), or whole brain radiotherapy (WBRT)? RECOMMENDATIONS: Level 1: Surgery + WBRT is recommended as first-line treatment in patients with single brain metastases with favorable performance status and limited extracranial disease to extend overall survival, median survival, and local control. Level 3: Surgery plus SRS is recommended to provide survival benefit in patients with metastatic brain tumors Level 3: Multimodal treatments including either surgery + WBRT + SRS boost or surgery + WBRT are recommended as alternatives to WBRT + SRS in terms of providing overall survival and local control benefits. SURGERY AND RADIATION FORMETASTATIC BRAIN TUMORS QUESTION: Should patients with newly diagnosed metastatic brain tumors undergo surgical resection followed by WBRT, SRS, or another combination of these modalities? RECOMMENDATIONS: Level 1: Surgery + WBRT is recommended as superior treatment to WBRT alone in patients with single brain metastases. Level 3: Surgery + SRS is recommended as an alternative to treatment with SRS alone to benefit overall survival. Level 3: It is recommended that SRS alone be considered equivalent to surgery + WBRT. SURGERY FOR RECURRENT METASTATIC BRAIN TUMORS QUESTION: Should patients with recurrent metastatic brain tumors undergo surgical resection? RECOMMENDATION: Level 3: Craniotomy is recommended as a treatment for intracranial recurrence after initial surgery or SRS. SURGICAL TECHNIQUE AND RECURRENCE QUESTIONA: Does the surgical technique (en bloc resection or piecemeal resection) affect recurrence? RECOMMENDATION: Level 3: En bloc tumor resection, as opposed to piecemeal resection, is recommended to decrease the risk of postoperative leptomeningeal disease when resecting single brain metastases. QUESTION B: Does the extent of surgical resection (gross total resection or subtotal resection) affect recurrence? RECOMMENDATION: Level 3: Gross total resection is recommended over subtotal resection in recursive partitioning analysis class I patients to improve overall survival and prolong time to recurrence.
