Craniotomy for resection of meningioma in the elderly: a multicenter, prospective analysis from the National Surgical Quality Improvement Program

J Neurol Psychiatry. DOI:10.1136/jnnp.2009.185074

Whether there is an increased surgical risk in elderly patients who undergo craniotomy for meningioma resection, remains a point of controversy. Utilizing multicenter, prospective data from the National Surgical Quality Improvement Program, the present study sought to address this controversy.

All patients who underwent a craniotomy for resection of intracranial meningioma between 1997 and 2006 at 123 VA hospitals around the country were included. After controlling for preoperative factors such as ASA class, race, diabetes mellitus, disseminated cancer, tobacco use, tumor location, and functional health status in a multivariate logistic regression model, the effect of elderly age (age greater than 70 years) on 30-day mortality was determined.

Our study included 1,281 patients who underwent surgical resection of an intracranial meningioma. The elderly cohort, represented 21.2% (n=258) of our total study population. Elderly patients had a higher 30-day mortality (12.0%) than younger subjects (4.6%) (P < 0.0001). Similarly, elderly patients were more likely to have one or more complications (29.8% vs. 13.1%, P < 0.0001). Multivariate logistic regression identified age, functional status, preoperative disseminated cancer, and tumor location as important predictors of 30-day mortality. After controlling for preoperative comorbidities and risk factors, the odds of perioperative mortality in elderly patients were 3 times that of younger patients (95% CI = 1.7 – 5.3, P = 0.0102).

After carefully controlling for various patient characteristics, ASA class and functional status, elderly patients have poorer outcome after surgical resection of intracranial meningioma than younger subjects.
