The prevalence of different histological types of brain tumors was analyzed in the Volgograd Region from the data of intraoperative biopsies over the period of 2001 to 2006. Gliomas were a dominant group (51.9%) at all study time intervals. Among them, there was a preponderance of glioblastomas (24.7%), anaplastic astrocytomas (21.1%), protoplasmatic astrocytomas (15.4%). The fact that heterogenic tumor tissue in a great deal of the study cases of malignant gliomas makes pathohistologists' opinion differ and suggests that there is a need for an in-depth study of intraoperative biopsy specimens, by using the existing antibody panels and developing new ones for immunohistochemical studies.
