Abstract

Previous studies have reported that alcohol dehydrogenase (ADH) isoenzymes possess diagnostic value in gastric cancer (GC). However, the prognostic value of ADH isoenzymes in GC remains unclear. The aim of the present study was to identify the prognostic value of ADH genes in patients with GC. The prognostic value of ADH genes was investigated in patients with GC using the Kaplan‑Meier plotter tool. Kaplan‑Meier plots were used to assess the difference between groups of patients with GC with different prognoses. Hazard ratios (HR) and 95% confidence intervals (CI) were used to assess the relative risk of GC survival. Overall, 593 patients with GC and 7 ADH genes were included in the survival analysis. High expression of ADH 1A (class 1), α polypeptide (ADH1A; log‑rank P=0.043; HR=0.79; 95% CI: 0.64‑0.99), ADH 1B (class 1), β polypeptide (ADH1B; log‑rank P=1.9x10‑05; HR=0.65; 95% CI: 0.53‑0.79) and ADH 5 (class III), χ polypeptide (ADH5; log‑rank P=0.0011; HR=0.73; 95% CI: 0.6‑0.88) resulted in a significantly decreased risk of mortality in all patients with GC compared with patients with low expression of those genes. Furthermore, protective effects may additionally be observed in patients with intestinal‑type GC with high expression of ADH1B (log‑rank P=0.031; HR=0.64; 95% CI: 0.43‑0.96) and patients with diffuse‑type GC with high expression of ADH1A (log‑rank P=0.014; HR=0.51; 95% CI: 0.3‑0.88), ADH1B (log‑rank P=0.04; HR=0.53; 95% CI: 0.29‑0.98), ADH 4 (class II), π polypeptide (log‑rank P=0.033; HR=0.58; 95% CI: 0.35‑0.96) and ADH 6 (class V) (log‑rank P=0.037; HR=0.59; 95% CI: 0.35‑0.97) resulting in a significantly decreased risk of mortality compared with patients with low expression of those genes. In contrast, patients with diffuse‑type GC with high expression of ADH5 (log‑rank P=0.044; HR=1.66; 95% CI: 1.01‑2.74) were significantly correlated with a poor prognosis. The results of the present study suggest that ADH1A and ADH1B may be potential prognostic biomarkers of GC, whereas the prognostic value of other ADH genes requires further investigation.
