Actos Warning Proclamation
Actos Warning : Tobacco smoking and occupational exposure have been the two major factors related to BC risk; however, not all smokers develop BC and not all cases of BC occurred in smokers or patients with chemical exposure. It has been proposed that there could be factors other than environmental that could affect the incidence on urothelial tumors. In fact, as for many other cancers, molecular researchers are trying to establish genetic alterations linked to carcinogenesis that could justify genetic predisposition.An important research has been conducted in patients with BC in relation to smoking and chemical exposure , trying to identify those patients with higher susceptibility of being affected by environmental carcinogens. Aromatic amines were established carcinogens for urothelium.

They could be inactivated by acetylation pathway, and it has been postulated that those patients with slow acetylation capability were more susceptible to BC than those that are rapid acetylators. NAT-1 and NAT-2 are N-acetyltransferase genes located on the short arm of human chromosome 8 and they are involved in amines inactivation. Reduction in NAT-2 activity has been suggested as mechanism for BC predisposition among patients exposed to environmental carcinogens such as aromatic amines.A number of SNPs have been reported in NAT-2 coding exon, as well as over 35 NAT-2 haplotypes have been identified (Hein 2006). Several of these haplotypes corresponded to NAT-2 slow acetylator phenotype and NAT-2 slow acetylation genotype has been related to higher risk of BC.

The Spanish Bladder Cancer Study is a hospital-based case-control study on BC conducted in five different areas in Spain that included 1150 cases and 1149 controls. They evaluated in this great population the association of several polymorphisms in NAT and GST genes with BC risk and their interaction with cigarette smoking. In addition, they reported a metaanalysis of 29 studies of NAT-2 and BC including 5096 cases and 6519 controls. They demonstrated that NAT-2 slow acetylators had a 40% increase in BC risk compared to rapid/intermediate acetylators with an OR of 1.4 (95% CI, 1.2-1.7). They could also demonstrate a significant multiplication interaction between NAT-2 slow acetylation genotype and cigarette smoking, that is, NAT-2 slow acetylators were especially susceptible to the adverse effects of cigarette smoking on BC risk. On the other hand, the metaanalysis performed corroborated their own data, being the summary on relative risk for NAT-2 slow acetylators compared to rapid/intermediate acetylators of 1.4 (Garcia-Closas et al. 2005).Other SNPs in different genes have been studied. Nucleotide excision repair (NER) pathway is a complex mechanism for repairing DNA damage and subsequently for preventing carcinogenesis. NER pathway included several genes, and different SNPs on those genes have been related to an increase in BC risk. Twenty- two SNPs on seven NER genes were evaluated in 1150 cases and 1149 controls included in The Spanish Bladder Cancer Study. Four of these 22 SNPs in NER genes could be significantly related to a small increase in BC risk and interestingly it could be demonstrated as a stronger association between BC and polymorphism in ERCC2 gene (ERCC2 R156R) for never-smokers compared with ever-smokers (Garcia-Closas et al. 2006).
Other study including 696 patients with BC and 629 controls evaluated the association with BC risk of a comprehensive panel of 44 SNPs in genes of NER pathway and genes involved in cell cycle control. They concluded that patients with higher numbers of variants in NER genes rather than single polymorphism are at increased risk for BC (Wu et al. 2006).
