Among the 45 patients with sufficient pre-CCRT material with tumor cells, PD-L1 expression in pre-CCRT material was not significantly associated with RFS (PD-L1-positive group versus PD-L1-negative group, median 28.8 versus 27.9 months, p = 0.546, respectively) and OS (PD-L1-positive group versus PD-L1-negative group, median 94.1 versus 92.8 months, p = 0.746, respectively). This evidence concerns the gene CD274 and neoplasm.
