As AKR1B10 expression almost diminished in gastric cancer, we evaluated the relationship between AKR1B10 and immunity by dividing samples with AKR1B10 expression into AKR1B10 high group with H score > 10, AKR1B10 medium group with 10 > H score > 0.5 and AKR1B10 low group with H score < 0.5. This evidence concerns the gene AKR1B10 and gastric cancer.
