Abstract

The prognostic value of histologic or cytologic features were examined in 317 patients with an astrocytic glioma. Of 46 features examined 7 morphologic characteristics of nucleus and 5 of mesenchyma correlated well with grading according to Kernohan. The morphological characteristics of nucleus are cellularity, atypical nuclei, polymorphism, multinucleated cells, hyperchromasia, gigantic nuclei and mitosis. For mesenchyma these were vascularity, vascular endothelial proliferation, vascular glomeruli, necrosis with palisade formation and necrosis without palisade formation. Scoring of these items on a scale from 0 to 4 enables us to establish a nucleus-score (max. 28) and a mesenchyma-score (max. 20). Nucleus-score + mesenchyma-score ≤ 10 corresponds with astrocytoma grade II, ≤ 20 with grade III and > 20 with grade IV. A low nucleus-score in grade II (< 5) predicts a long survival (> 10 years), a high nucleus-score a low survival (median 0.6 year). In grade III a low mesenchyma-score predicts a median survival of 1.25 years, a high mesenchyma-score a median survival of 0.38 year. This retrospective study shows that nucleus-score and mesenchyma-score correlate to grading according to Kernohan and are highly correlative to survival. [ABSTRACT FROM AUTHOR]
