Kaplan-Meier curves representing cumulative EFS (a) or OS (b) depending on the Oct4⁺ cells proportion. Cases with a low proportion of Oct4⁺ cells present ≤8.67% cells with Oct4 expression and those with high proportion have > 8.67% Oct4⁺ cells. Statistical significance is shown as the obtained p-values (p-value< 0.050) and survival rates are expressed as percentage of patients without the corresponding event [relapse/death in a) or death in b)] ± error at 5 years after diagnosis
