Abstract

Esophageal cancer is the fourth leading cause of cancer-associated fatalities and the fourth most commonly diagnosed cancer. In addition to environmental risk factors, genetic factors may have a significant role in esophageal cancer carcinogenesis. A hospital‑based case‑control study was conducted to evaluate the genetic effects of functional single‑nucleotide polymorphisms in the interleukin‑18 (IL‑18), IL‑18 receptor 1 protein (IL‑18R1), IL‑18 receptor accessory protein (IL‑18RAP) and IL‑28B on the development of esophageal cancer. In total, 380 esophageal squamous cell carcinoma (ESCC) cases and 380 controls were recruited for the present study. The IL‑18 rs360719 A>G, IL‑18R1 rs13015714 G>T, IL‑18RAP rs917997 C>T and IL‑28B rs8099917 T>G genotypes were determined. No association was observed between the IL‑18R1 rs13015714 G>T, IL‑18RAP rs917997 C>T and IL‑28B rs8099917 T>G polymorphisms and the risk of ESCC. However, in stratification analyses, a significantly decreased risk of ESCC associated with the IL‑18R1 rs13015714 G>T polymorphism and a significantly increased risk of ESCC associated with the IL‑18RAP rs917997 C>T polymorphism was evident among male patients and patients who smoked or consumed alcohol. These findings highlighted that functional polymorphisms IL‑18R1 rs13015714 G>T and IL‑18RAP rs917997 C>T may contribute to ESCC susceptibility among these subgroups. However, the present results were obtained with a limited sample size and further epidemiological studies are warranted to clarify the role of IL-18R1 and IL-18RAP variants in the development of ESCC.
