Abstract/OtherAbstract:
OBJECTIVES: Spinal meningiomas mainly occur in old patients, with a remarkable female prevalence. This study investigates the different features between younger and older patients in an adult population (>18 years).
MATERIALS AND METHODS: A surgical series of 120 adult patients operated on for spinal meningiomas at the Neurosurgical Clinic of the "Federico II" University of Naples is reviewed. In this series 117 patients with a sporadic spinal meningioma were divided in two groups: group I including 30 patients (25.6%) younger than 50 years of age, group II including 87 patients (74.4%) older than 50 years. 3 patients had a spinal meningioma and neurofibromatosis. Several parameters, including sex, predisposing factors, tumor location and growth, histology, recurrences, proliferation index Ki-67 LI, and outcome, are considered and compared in the two age groups.
RESULTS: Group I showed an incidence of high cervical spine (C1-C4) meningiomas higher than group II (23.3% vs 3.4%, p=0.026) and lower rate of thoracic tumors (60% vs 82.7%, p=0.04). No significant differences of histological type and Ki-67 LI were found. Group I had 2 cases of atypical meningiomas (6.6% vs 0%, ns). Recurrences occurred in 6.6% of group I and 2.6% of group II, with no significance. In recurrent meningiomas values of Ki-67 LI were significantly higher than values in not recurrent meningiomas (p=0.0001), whereas no difference of estrogen and progesterone receptor expression was noted.
CONCLUSIONS: Younger adult patients with spinal meningiomas show not rare occurrence of NF (9%) and significantly higher incidence of high cervical and lower incidence of thoracic localizations with respect to the older patients. On the other hand, there are not significant differences of histology, Ki-67 LI and recurrence rate, excepting for a slight difference for atypical meningiomas.
