Figure 1. Progression-free survival (A) and overall survival (B) according to Ap endo activity for grade II ependymomas treated with radiotherapy.

Figure 1

Tumors were divided into two equal groups (N = 12), with low (< 0.013 fmol/cell/min; solid line) and high (> 0.013 fmol/cell/min; dashed line) activity. Activity was measured in tumors obtained prior to radiation treatment. Curves were calculated by the method of Kaplan-Meier.
