Kaplan-Meier curves for the probability of recurrence and overall survival in patients with cancer of the uterine cervix according to RRM2 immunoreactivity of cancer tissue cores.

<p>(A) Patients with positive RRM2 tended to have a higher probability of recurrence (N = 99, <i>p</i> = 0.094), compared with the patients with negative RRM2. (B) Patients with positive RRM2 had significantly lower survival (N = 101, <i>p</i> = 0.016), compared with the patients with negative RRM2. RRM2, ribonucleotide reductase M2.
