Higher susceptibility to EGJA was also observed for carriers of the PD-1.9*T allele (lower for the PD-1.9 C/C genotype, OR = 0.81) and this observation was in accordance with the results obtained for gastrointestinal cancer (153), ESCC in females (163) as well as for ovarian cancer (173). This evidence concerns the gene PDCD1 and ovarian cancer.
