Abstract: Allele2specific PCR(AS2PCR) and multiplex differential PCR (MD2PCR) were used to identify the genotypes of CYP1A1 and GSTM1 in 68 lung cancer patients and 105 healthy cont rols. The result s showed that genotypes of CYP1A1 and GSTM1 could be detected simultaneously with AS2PCR and MD2PCR ; The frequency of CYP1A12Val/ Val in lung cancer patient s group was 12/ 68 (17. 6 %) , about 2. 052fold than that in healthy cont rols 9/ 105 (8. 57 %) , and the f requency of GSTM1 0/ 0 was 39/ 68 (57. 4 %) , remarkably higher compared with 42/ 105 (40 %) in healthy cont rols ( P < 0. 05) 1
