In Kaplan-Meier analysis, PD-L1low PCa showed the longest BCR-free survival (mean estimated 112 months), while mCXCL12medium showed best BRC-free survival rates among PD-L1high PCa (mean estimated 107 months), and PD-L1high/mCXCL12low, and PD-L1high/mCXCL12high showed short BCR-free survival times (mean estimated 52 months and 83 months, respectively; n = 151, χ2 = 12.99; p = 0.005; Figure 3C). Here, BCR is linked to posterior cortical atrophy.
