Abstract
Oligoastrocytomas form a poorly defined subgroup of glialtumors, and few clinical series have been reported.We performed a retrospective study to elucidate thehistopathological features of these tumors and to relatethe clinical signs and symptoms and proliferative potentialto survival. Oligoastrocytomas were defined as glial tumorswith at least 10% neoplastic astrocytes and 10%neoplastic oligodendrocytes; tumors were graded with the St.Anne-Mayo criteria for astrocytomas and oligodendrogliomas. Proliferative potentialwas estimated with antibodies against proliferating cell nuclearantigen (PCNA). Median survival of 52 patients (medianage, 42 years) was 75 weeks (range 2–703weeks). Actuarial 1-, 2-, 3-, and 5-year survivalrates were 67%, 43%, 40%, and 29%, respectively.For 15 patients with grade 3 and 33with grade 4 lesions (St. Anne-Mayo astrocytoma classification),median survival was 217 and 55 weeks, respectively.For 19 patients with grade 2 and 33with grade 3 lesions (St. Anne-Mayo oligodendroglioma classification),median survival was 305 and 55 weeks, respectively.Interobserver agreement between three experienced neuropathologists on identificationof astrocytes, oligodendrocytes, and unclassifiable cells was low,indicating considerable subjectivity in the histopathological diagnosis. MedianPCNA labeling indices correlated with tumor grade, butindividual values varied so widely within grades thatthey had no predictive value for survival. Ina multivariate analysis, symptoms of increased intracranial pressureand microvascular proliferation were independently associated with poorprognosis. The biological behavior of subgroups appeared tobe distinctly less aggressive than that of ‘pure’astrocytomas of similar grade. Better histopathological definition ofoligoastrocytomas and improved assessment of percentages of constituentcell types may allow more accurate prognosis.
