[ABO blood groups in glioblastoma multiforme]

The distribution of ABO blood groups was analysed statistically in 271 patients treated for glioblastoma multiforme. The control group included 500 patients treated for craniocerebral trauma. A statistically significant difference was observed in the distribution of ABO blood groups between these patient groups, with higher frequency of group A and lower of group O in the patients with glioblastoma multiforme.
