The recurrence of supratentorial meningiomas after surgery.

A series of 113 consecutive patients underwent surgical treatment for a supratentorial meningioma between January 1955 and January 1975. There were 73 women and 40 men. There were 10 postoperative deaths (8.8%). The surgical procedure was graded according to Simpson's classification. 18 patients had a recurrence (17.5%). Women had a preponderance for recurrence. In our series the recurrence rate was 13 for women (17.8%) and 5 for men (12.5%). There was no correlation with the age of the patient or site of the tumour. The grade of initial surgery and the histology of the tumour were shown to be important.
