Background:
The incidence of brain tumors in elderly patients is increasing. It has become possible to treat meningiomas in the elderly by several modalities. We developed a successful multimodal strategy to treat these patients.
Methods:
We registered 35 patients with meningiomas. Symptomatic meningiomas were treated surgically at the time of diagnosis (n=19). Of the 16 asymptomatic meningiomas, 5 were removed at the time of diagnosis. The other asymptomatic meningiomas (n=11) were treated conservatively and when the tumors increased in size, surgical treatment was considered. "Operated" patients with residual or recurrent tumors underwent radiosurgery with a gamma knife.
Findings:
Surgical mortality and morbidity were 4% and 16%, respectively. Of the 25 "operated" patients, 21 (84.0%) had a good Karnofsky scale (> or =80%) at discharge. In all but two of the 11 patients with asymptomatic, conservatively treated meningiomas, the tumors did not increase during the follow-up period. Gamma knife radiosurgery, performed to treat 3 residual and 1 recurrent tumor, resulted in very good tumor control and none of the tumors increased after gamma knife surgery.
Conclusions:
Meningiomas in elderly patients require a multimodal approach. Our strategy, which includes surgery, radiosurgery, and conservative treatment, resulted in good tumor control and made it possible for patients to pursue their activities of daily life.
