1p/19q co deleted oligodendrogliomas (ODG) are graded as WHO grade II or WHO grade III based on histology (as with 2007 WHO classification – “low grade” and “high grade”). WHO grade II is a favorable prognostic indicator independent of 1p/19q co-deletion.

Oligodendrogliomas are defined as IDH mutant and 1p 19q codeletion grade II tumours by the World Health Organization Classification of Tumors of the Central Nervous System 2016 ¹⁾.
