Figure 4. Serum hK2 up-regulation post-RT is associated with biochemical failure in 227 men treated with definitive EBRT for localized prostate cancer.
A. Waterfall plot of percent change in hK2 post-RT compared to baseline.
B. Comparison of biochemical relapse outcomes in men who had an hK2 gain post-RT (n=40) versus those who did not (n=187); (odds ratio 3.39 [95%CI 1.23–9.39], p=0.019).
C. Kaplan-Meier curves for Freedom of PSA progression by Hk2 gain status. Estimates at 72 months for Hk2 gain were 83.5% compared to 94.2% for those without an Hk2 gain (p=0.027).
