Outcome of elderly patients undergoing intracranial meningioma resection: a single-center experience.

Background: Higher life expectancy and higher mean age in general population created growing interest in medical and surgical management of meningiomas in elderly. It is well known that, due to possible complications, preoperative status and comorbidities, especially in aged people, should be carefully considered in the decision-making process. We described our experience with this kind of patients and analyzed the influence of complications on the outcome.

Methods: We conducted a monocentric retrospective study to evaluate outcome and complications in elderly patients that underwent intracranial meningioma surgery in our center in a ten-year period. Between January 2005 and December 2014, 107 patients - older than 70 years old - were operated for an intracranial meningioma. We excluded patients operated for a recurrent meningioma. We used the modified Dindo classification to describe complications and the Karnofsky Performance Status Scale and Glasgow Outcome Scale to evaluate the outcome at discharge and after a 6-month period.

Results: Eighty-four patients did not have postoperative complications, 10 patients had mild postoperative complications, while 13 patients suffered severe postoperative complications. As a group, patients with mild complications presented, six months after surgery, an average Karnofsky Performance Status better than preoperative one.

Conclusions: Even though the fragility is considered an important risk factor, surgery for symptomatic intracranial meningiomas should be considered also in elderly patients. The presence of early postoperative mild complications does not seem to worsen the average 6-month-KSP score.
