Interaction between CYP 2C19*3 polymorphism and smoking in relation to laryngeal carcinoma in the Chinese Han population
Cytochrome P450 (CYP) 2C19 metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids, which strongly promote proliferation of cancer cells in vitro and in vivo. Knowing that smoking is the most important risk factor for laryngeal carcinoma, we examined the relationships between CYP2C19*3 polymorphism, smoking and laryngeal carcinoma in the Chinese Han population. In a Chinese Han case-control study of 300 laryngeal carcinoma patients and 300 healthy controls, we investigated polymorphism in the CYP2C19 gene by PCR-RFLP analysis. The CYP2C19*3 AG + AA genotype was significantly more prevalent in laryngeal carcinoma patients (6.67 vs 2.67%; P = 0.02). Multiple logistic regression analysis showed smoking (odds ratio (OR) = 6.353, 95% confidence interval (CI) = 4.413-9.144; P < 0.001) and alcohol consumption (OR = 2.607, 95%CI = 1.130-6.016; P = 0.025) as independent risk factors for laryngeal carcinoma; there was a significant interaction between CYP2C19*3 and smoking (OR = 17.842, 95%CI = 13.32-31.102; P = 0.009). We conclude that CYP2C19*3 polymorphism is significantly associated with laryngeal carcinoma in the Chinese Han population.
