Interleukin-10 polymorphisms and nasopharyngeal carcinoma risk: a meta-analysis
It has been reported that interleukin-10 (IL-10) promoter genes (1082 A/G, 819 T/C, 592 A/C) are associated with nasopharyngeal carcinoma (NPC). However, the results remain controversial and ambiguous. To resolve inconsistencies in published data, we performed a meta-analysis to ascertain the association between IL-10 polymorphisms and NPC risk. Two case-control studies and two cohort studies were quantitatively analyzed to evaluate IL-10 promoter gene polymorphisms and NPC risk.
