These data reflected that immune cell PD1 expression is significantly associated with good prognostic pathological parameters, which agreed with Berntsson et al., who concluded that immune-specific PD1 is significantly associated with lower T and M stages, whatever the location of the tumor, as their study related the side to the prognostic impact of PD1 and PDL1 expressions [43]. The gene discussed is PDCD1; the disease is neoplasm.
