Abstract:
Objective To investigate the relationship between glutathione S-transferases P1(GSTP1)Ile105Val and glutathione S-transferases M1(GSTM1)single nucleotide polymorphisms(SNP) and the sensitivity to chemotherapy among patients with ad-vanced non-small cell lung cancer(NSCLC) .Methods We used gene sequencing analysis to determine the SNP of GSTP1 Ile105Val and PCR analysis to GSTM1 in DNA from peripheral lymphocytes of NSCLC patients .Totally 89 patients with NSCLC were trea-ted with platinum-based chemotherapy ,and clinical response was evaluated after 2 cycles .The association between GSTP1 Ile105Val and GSTM1 SNP and chemosensitivity were analyzed .Results The overall response rate was 29 .2% .Chemotherapy re-sponse did not show statistically significant differences between the wild genotypes and the variant genotypes for the GSTP1 Ile105Val and GSTM1 gene(P>0 .05) .Conclusion The polymorphisms of GSTP1 Ile105Val and GSTM1 may be not associated with sensitivity to chemotherapy in NSCLC patients .
