Popis: | The objective of this study was to determine whether nuclear parameters were associated with prognosis in glioblastoma multiforme. DNA indices, cell cycle parameters, and nuclear population densities were compared with patient survival. Selection criteria included the pathologic diagnosis of a cerebral glioblastoma multiforme, absence of therapy before surgery, and adequate tissue to measure each nuclear parameter studied. Nine cases accrued over a two year period. The amount of DNA per nucleus was quantified in fresh tissue specimens by nuclear-isolation flow cytometry in Vindelov's solution. One particular association was significant when tested by Cox models: The percentage of nuclei with S-phase amounts of nuclear DNA was a significant predictor of decreased survival (regression coefficient = 0.20, p = 0.04). The percentage of nuclei in the G0/G1 peak was marginally associated with longer survival. These data are evidence of an association between nuclei in certain phases of the DNA cell cycle and postoperative survival. |
