ABSTRACT
OBJECTIVE:
To investigate the relationship between susceptibility and prognosis of laryngeal cancer and genetic polymorphisms in CYP1A1 GSTM1.METHODS:
The genetic polymorphisms of CYP1A1 exon-7 and GSTM1 were analyzed by polymorphism-polymerase chain reaction (PCR) technique in peripheral blood leukocytes of 89 laryngeal cancer cases and 164 non-cancer controls.RESULTS:
Either in the frequency of CYP1A1 (W, MW, M) and GSTM1 negative individual of laryngeal cancer were significantly higher than that in the controls(P < 0.05). Combined genetype of CYP1A1 and GSTM1, that is CYP1A1 W/GSTM1 (-), CYP1A1 MW/GSTM1 (-), CYP1A1 M/GSTM1 (+), CYP1A1 M/GSTM1 (-) had higher risk than those combined genotypes, which ratios were 1.42 (0.62-3.22), 1.67 (0.7-4.03), 2.55 (1.0-6.54) and 4.02 (1.65-9.79), respectively. Statistic analysis suggested an interaction between smoking and CYP1A1 M/GSTM1 (-) genotypes polymorphisms which increase risk of laryngeal cancer. There was no significant difference in the frequency of CYP1A1, GSTM1 individual with the development and prognosis of laryngeal cancer.CONCLUSION:
The present datas suggested that genetic polymorphisms of CYP1A1 and GSTM1 were susceptible to laryngeal cancer. Individuals with CYP1A1 M or GSTM1 (-) had increased risk of developing laryngeal cancer, but individuals with combined CYP1A1 M/GSTM1 (-) and smoking were more susceptible. Genetic polymorphisms of CYP1A1 and GSTM1 are not related with clinic process of laryngeal cancer.
