Guidelines for Multiple Brain Metastases Radiosurgery.

Guidelines for Multiple Brain Metastases Radiosurgery. Prog Neurol Surg. 2019 May 16;34:100-109 Authors: Niranjan A, Monaco E, Flickinger J, Lunsford LD Abstract Stereotactic radiosurgery (SRS) is an effective treatment for patients with multiple brain metastases. Three decades of increasingly powerful scientific studies have shown that SRS improves outcomes and reduces toxicity when it replaces whole-brain radiation therapy (WBRT). Expert opinion surveys of clinicians have reported that the total intracranial tumor volume rather than the number of brain metastases is related to outcomes. As a result, an increasing number of treating and referring physicians have replaced the reflex use of WBRT with SRS, unless the patient has miliary disease or carcinomatous meningitis. In the current era of immunotherapy and targeted therapies with potentially increased systemic disease survival, 10 or more tumors are routinely treated with SRS alone at most academic medical centers. In a single SRS session we routinely treat patients with cumulative tumor volumes of 25 cm3 even if they have ≥10 metastases. PMID: 31096242 [PubMed - as supplied by publisher]
