One strategy has exploited correlations among specific molecular markers and healing reaction. the 1st such “breakthrough” in high-grade glioma was once the statement that lack of chromosomes 1p and 19q uniformly are expecting chemosensitivity in anaplastic oligodendrogliomas (1).

Chapter 1 / Histologic Classifications 19 Fig. 16. Gliomatosis cerebri often resembles a low-grade astrocytoma with spindled nuclei (hematoxylin and eosin, original magnification u200). ” The cells contain rounded oligodendrocyte nuclei with increased eosinophilic cytoplasm filled with intermediate molecular weight glial filaments (Fig. 19). High-grade tumors are generally more cellular than low-grade tumors (Fig. 20). Nuclear pleomorphism is more prominent and in some tumors may approach the variation in nuclear size and shape that marks high-grade astrocytomas.
