OBJECT: The aim of this study was to review the outcome of patients undergoing surgery for treatment of lateral-ventricle metastases. METHODS: Imaging information and chart reviews of operative reports were used to conduct a retrospective analysis in 29 patients who underwent resection of lateral-ventricle metastases at the authors' institution between 1993 and 2007. Clinical and neurosurgical outcomes and recurrence rates were studied. RESULTS: The mean patient age was 56 years (range 20-69 years); 66% of patients were male. Single intraventricular metastases occurred in 69% of patients, and 55% of them had systemic metastases. The 30-day postoperative mortality rate was 7%. There was intracerebral tumor recurrence in 41% of patients, with 1 patient undergoing a second operation for this. The median postoperative survival duration for 28 patients (excluding 1 patient with preoperative leptomeningeal disease) was 11.7 months; the 3- and 5-year survival rates were 17 and 11%, respectively. Univariate analysis identified factors significantly influencing survival, including the preoperative Karnofsky Performance Scale (KPS) score (p = 0.02), the number of cerebral metastases (p = 0.02), the presence of primary renal cell carcinoma (RCC) (p = 0.02), and the resection method (en bloc vs piecemeal; p = 0.05). The presence of extracranial metastases did not significantly influence survival. Multivariate analysis showed that the preoperative KPS score (p = 0.002), the presence of primary RCC (p = 0.039), and the resection method (en bloc vs piecemeal; p = 0.008) correlated significantly with survival time. CONCLUSIONS: Surgery is an important component in the management of intraventricular metastases. To the authors' knowledge, this is the first study focusing totally on resection of lateral-ventricle metastases. The authors found that patients with primary RCC, those with a favorable preoperative KPS score, and those who underwent en bloc resection had a better outcome than others.
