The stratified analysis showed that rs1</span>800796</span> G allele carriers (GG/CG) were associated with an increased risk of gastri</span>c cancer in the following subgroups: age >64 years old (OR<sub>adjusted</sub> = 1.67, 95% CI = 1.17-2.39), female (OR<sub>adjusted</sub> = 1.82, 95% CI = 1.09-3.05), positive for <i>H. pylori</i> infection (OR<sub>adjusted</sub> = 1.54, 95% CI = 1.07-2.22), non-cardiac gastric cancer (OR<sub>adjusted</sub> = 1.53, 95% CI = 1.15-2.04), stage T3-T4 tumor (OR<sub>adjusted</sub> = 1.41, 95% CI = 1.06-1.88), and gastric cancer with median to high differentiation (OR<sub>adjusted</sub> = 1.45, 95% CI = 1.08-1.96).
Further subgroup analyses based on ethnicities of participants revealed that the IL-4 rs2243250, IL-6 rs1800796 and IL-8 rs4073 polymorphisms were significantly associated with the risk of GC in Asians.
Epidemiological studies have evaluated the associations between interleukin-6 (IL-6) gene -174 C/G (rs1800795) and -572 C/G (rs1800796) polymorphisms and gastric cancer (GC) risk, but results and conclusions remain controversial.
The prognostic role of the functional IL-6 (promoter) rs1800795 and the IL-6R (receptor) rs8192284 single nucleotide polymorphisms (SNP) was studied in patients with advanced gastric cancer treated with palliative chemotherapy.
Epidemiological studies have evaluated the associations between interleukin-6 (IL-6) gene -174 C/G (rs1800795) and -572 C/G (rs1800796) polymorphisms and gastric cancer (GC) risk, but results and conclusions remain controversial.
