The <i>let-7</i>-related polymorphism rs3811463 in <i>LIN28A</i> is associated with the susceptibility to gastric cancer and the <i>let-7</i>-related polymorphism rs10889677 in <i>IL23R</i> is associated with the prognosis of gastric cancer.
We investigated whether the association between IL23R +2199 rs10889677 and gastric cancer risk varies by clinical characteristics and the prognostic value of the polymorphism in a case-control study.
