Defining non-recurring meningiomas as those without recurrence at least 8 years postoperatively, Maj-Lis Møller and Otto Brændstrup detected no significant differences in the Ki-67 labeling index between recurring and non-recurring meningiomas, when either totally and subtotally resected tumors were studied or when only radically resected tumors were studied (52). Here, MKI67 is linked to meningioma.
