Fig 3. Event Free Survival (EFS) and Overall Survival (OS) according to the histological grade and the 9p deletion status.

Fig 3

9p deleted anaplastic oligodendrogliomas (OIIId) are associated with shorter EFS and OS than non-deleted anaplastic oligodendrogliomas (OIIIw) and low grade oligodendrogliomas (OII) (a and b). Interpretation of p16 expression is radically different according to the 9p status in anaplastic oligodendrogliomas (OIII): hyperexpression of p16 (>30%) is correlated to shorter EFS and OS in non-deleted OIII (c and d) whereas absence of expression of p16 (<7%) is correlated to shorter EFS and OS in deleted OIII (e and f).
