Similarly, while Xylinas et al. [23] found no association between PD-L1 (B7-H1) expression and disease recurrence, cancer-specific mortality, or overall mortality, they did reveal a tendency towards a positive association with increased overall mortality (HR: 1.97, CI: 0.99–3.89, p = 0.06) in a subcohort of organ-confined UC patients. Here, CD274 is linked to cancer.
