CD44 and gastric cancer: Data from the literature have indicated that the CD44 gene rs8193 is associated with tumor recurrence; the median tumor recurrence time for the T allele is 9.4 years, while that for the wild homozygous CC genotype is 5.4 years (hazard ratio (HR) = 0.51, 95% CI = 0.35‐0.93, P = .022).8 A similar result was found in a gastric cancer study conducted on the Chinese population.
