ABSTRACT
Introduction: histological stage and extent of initial surgical resection has been considered decisive prognostic factors in meningiomas.
Objective: to determine the behavior of recurrent intracranial meningiomas operated at Abel Santamaría Cuadrado Hospital during the period 2010-2013.
Method: a quasi-experimental, descriptive and applied longitudinal study was carried out. The study group consisted of 46 patients operated at the Neurosurgery
Service, while the sample comprised 8 relapsing patients who met the inclusion criteria. Specific data is collected from the individuals´ medical records. A database was compiled to facilitate information processing, with the help of the professional software SPSS 15.0. To carry out the analysis we used comparison test ofproportions for independent samples.
Results: the degree of recurrence is higher in the skull base (50%) and in the parasagittal region (33.3%). More than 50% of the operated cases belong to stage
I, while those who relapsed were in stages II and III (62.5%). The shortest time for recurrence was 14 and 6 months in patients with high-grade malignancy and subtotal removal. The site of recurrence was more related to the temporal area oft he skull base and the greater wing of the sphenoid.
Conclusions: the recurrence of intracranial meningiomas was associated with the histological stage, tumor resection, the surgical technique used and the approach, regardless of the extent of surgical resection.
