Abstract Survivin is a member of novel inhibitor of apoptosis protein family which expressed in human cancers. The molecular detection of bladder cancer by targeting Survivin as a novel marker may be useful in the occurrence and progression of cancer. We genotyped Survivin -31G>C, -1547A>G and -241C>T by PCR-restriction fragment length polymorphism to evaluate the risk of bladder cancer (BC) in 200 BC patients and 200 healthy controls from North Indian cohort. We observed significant increased BC risk associated with variant CC genotype of Survivin -31G>C having 2.6 fold risk. The variant genotype of Survivin -1547A>G was significantly associated with BC risk (P = 0.047). In case of Survivin -241C>T the protective genotype for BC was heterozygous (P = 0.035). Smoking significantly modulated the risk in patients with Survivin -1547A>G polymorphism. Variant as well as hetero genotype of Survivin -31G>C was associated with reduced risk of recurrence (HR = 0.22 and 0.35) in BC patients receiving BCG treatment thus showing least survival. Furthermore, the haplotype analysis revealed C-A-T haplotype to be associated with reduced BC risk. Our findings suggested that the functional polymorphism -31G>C, -1547A>G and -241C>T in the promoter of Survivin gene may play a significant role in mediating the BC risk among North Indian cohort.
