title: Anterior visual pathway meningiomas primarily resected between 1978 and 1988: the Mayo Clinic Rochester experience.
abstract: The relapse rate, overall survival, and factors associated with a decreased recurrence-free survival rate in patients with anterior visual pathway (AVP) meningioma were compared with these features in patients who had meningiomas at other sites. Management of these patients is discussed. A review of the records of 581 consecutive patients who had primary resection of meningiomas between 1978 and 1988 identified 43 patients with AVP meningioma. Multiple clinical, surgical, and pathologic factors at the initial examination were analyzed to assess their association with recurrence, and the patients who had AVP meningioma were compared with patients who had non-AVP meningiomas to determine the factors that may influence recurrence. Recurrence-free and overall survival rates were determined. The AVP tumors were associated with a higher rate of recurrence. Subtotal resection was more common in the AVP tumors, but it alone was not associated with the decrease in recurrence-free or overall survival rates. Several factors that may explain the higher recurrence rate in patients with AVP meningioma were identified. Anterior visual pathway meningioma is associated with a higher rate of recurrence than are meningiomas at other sites. Operation remains the mainstay of treatment for symptomatic nonseeing eyes. Radiation therapy seems to be effective for managing recurrent tumor.
