Oligodendroglioma: CD44 as a possible prognostic opportunity

CD44, in its standard form as well in its isoforms, is a cell surface adhesion glycoprotein which occurs in a widevariety of non-neoplastic and neoplastic ceils. CD44 has been considered to be implicated in tumoral growth andin metastatic potential. We studied the immunohistochemical expression of CD44 standard in 30 oligodendrogliomas(19 primary lesions and 11 recurrences) in order to verify its possible prognostic role. Twelve primary oligoden-
