Furthermore, when the lung cancer patients were analysed by tumour type, a statistically significant increase in the GSTM1 null genotypes (62%; n = 71) was seen in the squamous cell carcinoma group, with an odds ratio of 2.1 (95% confidence interval 1.2-3.8).

The role of CYP1A1 inducibility was found to be more important than that of GSTM1 polymorphism, because the non-inducible CYP1A1 was associated solely with bronchial tumours (P = 0.001), mainly squamous cell carcinomas.
