CD274 and gastric cancer: 2017 for 22C3 antibody and was proved had better predictive ability than TPS in gastric cancer.22 In our study, combined PD‐L1 expression showed comparable prognostic significance with TC and IC for both SP263 and SP142 (Table 1); moreover, combined PD‐L1 staining was easier to evaluate than TC and IC, so combined PD‐L1 positive by IHC might be a better option and a reliable predictive marker in DLBCL.
