OLIGODENDROGLIOMAS

Although oligodendrogliomas cannot be considered benign tumors, many a re slow-growing indolent tumors for which prolonged life expectancy is the rule. Others behave in a more aggressive, malignant fashion, as t heir histologic characteristics would predict. The treatment for oligo dendrogliomas is evolving, with conservative management still reserved for nonanaplastic tumors, and increasingly aggressive systemic therap ies are being developed for more aggressive or recurrent tumors.
