This study was conducted to examine: 1) whether the NAT2 genotypes are risk factors for bladder cancer, 2) to study possible association of tobacco usage with NAT2 genotype of these patients.


This case control study was undertaken over a period of 19 months and included 101 bladder cancer patients and 110 controls. The NAT2 genotypes were identified by PCR-RFLP method in peripheral blood DNA samples. Genotypes frequencies and the association of the genotypes among patients and controls group were assessed by Chi2 test and Fisher exact test.


The NAT2 fast acetylator genotype frequency of slow or fast acetylator genotypes was not significant in bladder cancer patients alone (OR = 1.18, 95% CI: 0.69 - 2.03, p value = 0.583) or combination with tobacco users (OR = 0.84, 95% CI: 0.328 - 2.125, p value = 0.813) when compared with controls.


These data demonstrate that the NAT2 fast or slow acetylators genotype did not associated with the risk of developing bladder cancer in North Indian population when compared with controls.
