Total surgical excision is the main goal of therapy for intracranial meningiomas. The controversy today involves the efficacy of postoperative radiation therapy. To evaluate this question, 132 patients with benign intracranial meningiomas, treated between October 1964 and April 1985, were evaluated. All patients had a minimum 2-year follow-up. The actuarial local control rates at 10 years for the three treatment groups were as follows: subtotal excision alone, 18%; subtotal excision plus postoperative radiation therapy, 82%; and total excision alone, 77%. The actuarial determinate survival rates at 10 years were 49%, 81%, and 93%, respectively. Postoperative radiation therapy was also effective for patients treated at the time of the first recurrence, with an actuarial local control rate at 10 years after salvage treatment of 30% for patients treated with surgery alone and 89% for patients receiving postoperative radiation therapy at the time of salvage. This analysis suggests that radiation therapy has a significant role in the treatment of subtotally excised and recurrent intracranial meningiomas.
