title: MIB-I as a proliferative activity marker of the multiform glioblastomas.
abstract: MIB-I is a proliferative activity marker of multiform glioblastomas which are the most frequent tumors of the central nervous system. They are characterizad by differential rate and prognosis. The aim of the study was to determine the proliferative activity of multiform glioblastomas and estimation of the correlation between tumors' proliferative activity and tumors' localization, size, patients' age and sex. 24 patients (18 females and 6 males) with multiform glioblastomas were analyzed. The mean patients' age was 52.1. The proliferative activity was calculated as a proliferation index: IP for MIB-I. Cells with positive reaction were determined by MIB-I which was compared to all neoplastic cells. The most frequent localization of the tumors were frontal and temporal lobes of the brain. The size of the tumors ranged from 2.5 to 5.3 cm (mean 3.9). Mean IP was 43.2 (SD+/-17.4). We found no correlation between IP MIB-I and localization of the tumor, patients' age and sex. There was a marginal statistically significant correlation between IP MIB-I and size of the tumor (p=0.005).
