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.
