Validated by Daniels TB, Brown PD, Felten SJ. Validation of EORTC prognostic factors for adults with low-grade glioma: a report using intergroup 86-72–51. Int J Radiat Oncol Biol Phys. 2011;81:218–24. doi: 10.1016/j.ijrobp.2010.05.003

The low risk group had
significantly better median OS (10.8 vs. 3.9 yrs:
p<.0001) and PFS (6.2 vs. 1.9 yrs: p<.0001) than the
high risk group.
