Intracranial meningioma is a common benign tumor Although tumor mass might have
been totally removed aggravation of symptoms or recurrence of mass may sometimes be
noticed. Histopathologic finding has been known as one of probable prognostic tractors
in meningiomas. In this study, correlation between DNA contents and histopathologic
findings were evaluated to elucidate further such factors having role in the recurrence or
prognosis in meningiomas.
Seventy four cartes of meningiomas were selected to review clinical prognosis and
histopathologic findings. The speciemens were re-evaluated with flow cytometry to get
DNA histogram DNA fractions and proliferation index(PI) were calculated. The
correlations were statistically analyzed with t-test and ANOVA test.
Benign meningiomas were 53(71.6%). atypical 19(25.7%), and malignant 2(2.7%) PI of
being was 10.80¡¾1.36 and that of atypical being 18.00¡¾5.19. Diploid cases were 48 in
number(64.9%) and aneuploid 26(35.l%). PI of diploid Was 8.10¡¾5.56 and that of
aneuploid 24.06¡¾18.51. DNA index Was 1.00¡¾0.00 in benign. 1.00¡¾0.33 in atypical, and
1.50¡¾0.71 in malignant. There was one case(2%) in benign, 2(11%) in atypical and
2(100%) in malignant meningioma which showed recurrence(p=00002). In benign
meningioma, 1 out of 4 subtotally removed cases recurred whereas atypical and
malignant meningiomas recurred even in totally removed cases.
In conclusion. histopathologically malignant meningiomas have not be6n always
aneuploid If total removal is done in benign tumor, long-term follow-up is not needed
because of no recurrence and no aggravation of symptom. Atypical meningioma with
aneuploid and high PI(above 24) should be followed in longer duration, and malignant
meningioma should be closely observed thus to their higher recurrence rate.
