title: Glioma prostaglandin levels correlate with brain edema.
abstract: The present study was designed to prospectively investigated the prostaglandin (PG) levels and extent of peritumoral edema in 30 cases of glioma by using methods of radioimmunoassay and imaging. Both TXB2 and 6-keto-PGF1 alpha levels in all glioma groups went up over that in the control group. TXB2 level and ratio of TXB2/6-keto-PGF1 alpha were markedly increased with the extent of tumor malignancy. Water concentration in anaplastic astrocytoma and glioblastoma were significantly elevated. Difference in TXB2 level and TXB2/6-keto-PGF1 alpha ratio among three edema grades were statistically significant. TXB2 level and ratio of TXB2/6-keto-PGF1 alpha were closely correlated with water concentration (r1 = 0.53, r2 = 0.72, P < 0.01). Our findings suggested that the metabolism of PG in glioma were in the state of disorder, and that the imbalance between PGI2 and TXA2 may be one of factors which affect the formation of peritumoral edema.
