IFNA1 and neoplasm: The negative impact on DFS of COX‐2T and PD‐1S and the positive impact of HLA‐IS, HLA‐IT, and HLA‐DRS have a potentially straightforward interpretation: COX‐2T has been shown to mediate inhibition of type‐I interferon (IFN) and T cell‐mediated anti‐tumor responses 20, while a high expression of PD‐1 can mark functionally impaired (exhausted) T cells at tumor sites 21.
