OBJECTIVE: The clinical course of high-grade central nervous system gliomas is occasionally complicated by hydrocephalus. The risks of shunt placement and clinical outcome following CSF diversion in this population are not well defined.
METHODS: The authors retrospectively reviewed the outcomes of patients with pathologically confirmed WHO grade III or IV gliomas with shunt-treated hydrocephalus at their institution. Outcomes of patients in this cohort were compared with those of patients who underwent shunt treatment for normal pressure hydrocephalus (NPH). Hospital-reported outcomes in a national database for malignant primary brain tumor patients undergoing a ventricular shunt procedure were also reviewed.
RESULTS: Forty-one patients undergoing CSF shunting between 2001 and 2016 at the authors' institution were identified. Noncommunicating and communicating hydrocephalus occurred at similar rates (51.2% vs 48.8%). Symptomatic improvement after shunting was observed in 75.0% of patients. A major complication occurred in 17.1% of cases, with 2 patients suffering an intracranial hemorrhage. Prior administration of bevacizumab was significantly associated with the incidence of hemorrhage (p = 0.026). Three patients (7.3%) died during admission, and 8 (19.5%) died within 30 days of shunt placement. The presence of ependymal or leptomeningeal enhancement was more common in patients who died within 30 days (75.0% vs 11.1%, p = 0.001). Six patients (18.1%) required readmission to the hospital within 30 days of discharge. Revision surgery was necessary in 7 patients (17.1%). The median time from shunt placement to death was 150.5 days. In comparison with patients with NPH, shunt-treated high-grade glioma patients had increased in-hospital (7.3% vs 0.5%, p = 0.008) and 30-day (19.5% vs 0.8%, p < 0.001) mortality but no difference in the incidence of revision surgery (17.1% vs 17.5%, p = 0.947). Similarly, in the national Vizient Clinical Database Resource Manager, shunt-treated patients with malignant primary brain tumors had an increased length of stay (6.9 vs 3.5 days, p < 0.001), direct cost of admission ($15,755.80 vs $9871.50, p < 0.001), and 30-day readmission rates (20.6% vs 2.4%, p < 0.001) compared with patients without brain tumors who received a shunt for NPH.
CONCLUSIONS: Shunting can be an effective treatment for the symptoms of hydrocephalus in patients with high-grade gliomas. However, the authors' results suggest that this procedure carries a significant risk of complications in this patient population.
