MMP26 and posterior cortical atrophy: As shown in Figure 3A, MMP11 and MMP24 is the risk factors for unfavorable RFS (MMP11: HR=3.12, 95% CI=1.91-5.09, P<0.001; MMP24: HR=1.87, 95% CI=1.15-3.06, P=0.007), while MMP1 (HR=0.59, 95% CI=0.37-0.95, P=0.034), MMP7 (HR=0.73, 95% CI=0.46-1.17, P=0.186) and MMP26 (HR=0.40, 95% CI=0.25-0.64, P<0.001) are the protect factors for PCa patients and associated with the prolonged RFS Subsequently, we analyzed the correlation of the five MMPs expression and the expression form in different clinicopathological subgroups.
