Some authors [61] found that dMMR was associated with decreased OS (n = 124; p = 0.005), while others (n = 220) [29,37] described that cases with loss of ≥1 MMR protein and PD-L1 expression in tumor-infiltrating lymphocytes (TILs) had a significantly higher risk of biochemical recurrence (BCR) (p = 0.045). The gene discussed is CD274; the disease is neoplasm.
