Abstract

Objective

To prospectively assess mortality, morbidity and the functional and symptomatic outcome following intracranial surgery for meningiomas in elderly patients at two neurosurgical institutions in Norway.

Methods

Patients ≥60 years who underwent craniotomies for intracranial meningiomas at Oslo University Hospital and Haukeland University Hospital in 2008 and 2009 were included (n = 54). Outcome was assessed at 6 months.

Results

Thirty-five females and 19 males of median age 70 (60–84) years were assessed pre- and post-operatively, 87% attended follow-up at 6 months. The surgical mortality rate was 5.6% at 30 days and 7.4% at 3 and 6 months. The rates of complications were: post-operative hematomas 5.6%, deep venous thrombosis 1.9%, osteitis 1.9%, cerebrospinal fluid disturbances 13.0% and neurological sequelae 13.0%. Surgery resulted in a significant improvement in the MMSE score, with a further 14.9% obtaining scores of ≥25 without a significant change in the level of independence according to the Karnofsky performance scale. QoL assessments showed good functioning post-operatively compared to other cancer patient groups, yet slightly reduced when compared to data from the general population.

Conclusion

In our series, we found that meningioma surgery in the aging patient carries a higher risk of mortality and morbidity compared to intracranial tumor surgery in general. Our findings indicate, however, that the survivors have improved cognitive function and acceptable QoL, and we did not see any significant decrease in the proportion of independent patients according to the KPS.
