ABSTRACT
Background:
Meningiomas are the most common intracranial tumours; they accountfor 13%–26% of all the primary intracranial tumours. Skull base meningiomas make up 25% of allmeningiomas and are one of the most difficult intracranial tumours to be managed surgically. Thisis due to the fact that it is difficult to approach the lesions which are also close to vital structuressuch as cranial nerves and major blood vessels. Despite the abundance of these cases in Malaysia,local data on meningiomas is scarce.Methods:
This is a retrospective study consisting of 199 patients with meningiomaswho have been operated at the Kuala Lumpur General Hospital from January 2010–December2014. They were categorised into skull base and non-skull base groups. Demography, tumourcharacteristics, and patient outcomes were analysed. Kaplan-Meier survival curves as well asCox hazard univariable and multivariable regressions for the possible predictors of survival wereanalysed.Results:
97.5% of the patients (n = 194) had WHO grade I meningioma and only fivepatients had WHO grade II meningioma. There was a female predominance (n = 134; 67.3%), witha male-to-female ratio of 12. Some 27.1 % patients had skull base meningiomas. Patients with skullbase meningiomas had poorer outcomes and discharge conditions (n = 23; 42.6% P < 0.01), inaddition to higher risk of incomplete resections (n = 34; 63% P < 0.01). Multivariate cox hazardregressions showed that the skull base meningioma group had four times the risk of death of thenon-skull base group.Conclusions:
Symptomatic meningiomas can be curative if the tumour is completelyremoved. Our study has revealed that skull base meningiomas which were operated locallyhad higher rates of incomplete resection and poorer surgical outcomes as compared to the nonskullbase group. Patients with skull base meningiomas had four times the risk of death vis-à-visnon-skull base ones. More local studies are needed to look into skull base meningiomas for theimprovement of its surgical outcomes.
