Results of surgical treatment of patients with cerebral oligoastrocytoma
Keywords:oligoastrocytoma, histological structure, surgical treatment
Introduction. Long-term results of surgical treatment of 163 patients with cerebral oligoastrocytoma (OA) taking into consideration their histological structure were analyzed.
Materials and methods. OA of the II degree of anaplasia were diagnosed in 32 (19.6%) cases, of the III degree — in 123 (75.4%). In 8 (5%) cases OA structure was similar to glioblastoma.
Results. In OA tissue in 52 (32%) cases oligodendroglial component predominated, in 48 (29%) — astrocytic, in 63 (39%) — relatively even distribution of cells of both components. Life expectancy at OA of the II degree of anaplasia was in average (55±12.3) months, of the III degree — (24±6.5) months, of the III–IV degree — (6±2.3) months.Conclusions. Long-term results of surgical treatment of patients with OA significantly correlate with features of these tumors histological structure.
