It is thought that the biological aggressiveness of meningioma is closely related to the
development of peritumoral edema. However, the effects of mechanical tumor factors on
the venous return of underlying brain tissue, as well as those of MIB-1 or p53
immunoreactivity on the brain edema formation are still not clear. To identify factors
which may influence meningioma-associated peritumoral edema development, the authors
examined 28 histologically proven intracranial meningioma(22 benign, 4 atypical, and 2
malignant, meningioma patients). Correlation between the degree of brain edema and
various factors including volume of the tumor, venous sinus involvement, tumor location,
histologic subtypes, MIB-1 labeling index(LI), and immunoreactively of p53 protein was
analyzed retrospectively. The degree of brain edema(edema ratio) was measured by
maximum edema area to maximum tumor area as seen on T2 and T1 enhanced
magnetic resonance images, respectively.
Mean maximum tumor area and the volume of the tumor were 15.7§² and 50.2§²,
respectively. The mean area of maximum edema extension was 23.3§² and the mean
ratio between maximum edema area and tumor area was 1.90(range : 0-11.5). Tumor
volume and the area of edema showed significant correlation(p=0.015). MIB-1 LI,
however, correlated inversely with edema ratio((p=0.039), p53 protein expression, venous
sinus involvement, age, sex, and histologic characteristics did not correlated with edema
area or ratio.
In conclusion, this study showed there was inverse correlation between development
and MIB-1 LI, and no correlation with p53 expression. It was thus speculated that
peritumoral edema in meningioma may not be a sing of biological aggressiveness.
