ABSTRACT
OBJECTIVE@#To analyze the association between genetic polymorphisms of xenobiotic- metabolizing enzymes GSTM1, GSTT1, GSTP1 and susceptibility to laryngeal carcinoma from the Han people in Guangdong zone.@*METHOD@#A case-control study was conducted involving 233 LSCC (laryngeal squamous cell carcinoma) patients and 102 healthy controls to investigate the association between polymorphisms of GSTM1, GSTT1, GSTP1 (Ile/Val) and LSCC from the Han people in Guangdong zone. All blood samples of the Han people from the Guangdong zone was analyzed with methods of PCR, ASA and the DNA sequencing technique with sequenator. We explored the association between polymorphisms and the clinical pathologic characteristics of LSCC. The data was processed with SPSS13.0. Odds Ratios (ORs) with 95% CI for relevancy intensity were calculated using binary logistic regression analysis.@*RESULT@#The frequency of GSTM1(-) and GSTT1(-) genotype was higher in LSCC than that in healthy controls (OR = 2.61, 3.05, P 0.05).@*CONCLUSION@#There may be an association between the susceptibility to carcinoma and GSTT1(-), GSTM1(-) genotype. The GSTT1(-) polymorphism c gene cooperating with heavily smoking boost up the susceptibility of individual to laryngeal carcinoma. The GSTM1(-) polymorphism c may not cooperating with smoking during carcinogenesis of LSCC in the Han people in Guangdong zone. The morphisms of GSTT1 and GSTM1 gene may affect the carcino-genesis of LSCC in the Han people in Guangdong zone. There may be no association between the susceptibility to laryngeal carcinoma and the GSTP1(Ile/Val) type.
