Background: Intracranial meningiomas are the second most common tumor of the central nervous system. Grade I tumors are the most common variety of meningioma and have a benign course. Surgery is the mainstay of treatment. Radiotherapy (RT) decreases the local recurrence rates and progression in patients with subtotal excision (STE). The authors present our institute's experience in combined modality management of 18 successive patients of Grade I meningioma. Materials and Methods: We retrospectively reviewed 18 patients of Grade I meningioma treated in our institute from 2003 to 2011. Clinical characteristics and treatment modality in form of surgery and RT were noted. Statistical analysis was done with regards to recurrence free survival and overall survival using Kaplan-Meier survival analysis. Results: The median age of the patients was 52.5 years. Seven patients were males and 11 patients were females. The median duration of symptoms was 8 months. Headache was the most common presenting symptom followed by vomiting, seizures, motor weakness and visual deficits. Five patients underwent complete excision while 13 had STE. 11 patients received early RT while 5 patients received RT at recurrence. Median RT dose delivered was 50 Gy. RT had significant effect on local control especially in subtotal resections, with overall 93.75% local control rates. Conclusions: Grade I meningiomas represent a benign neoplasm. The mainstay of therapy is gross total resection at the initial surgery. Postoperative adjuvant RT should be offered to patients with subtotal resection. Long-term follow-up is important as local recurrences and progression can develop years after the initial treatment.
