Abstract:
Thrombospondin-1 (TSP-1) is a glycoprotein that plays a major role in bladder cancer. We investigated the relationship between the distribution of the TSP-1 -696 C/T polymorphism (rs2664139) and the clinical features of bladder cancer. TaqMan assay was used to determine the genotype among the 609 cases and 670 controls in a Chinese population. Logistic regression was used to assess the association between the polymorphism and bladder cancer risk. Compared with the CT/TT genotypes, the CC genotype was associated with a significantly increased risk of bladder cancer (adjusted odds ratio [OR] 1.43, 95% CI 1.01-2.04), which was more prominent among the male participants (OR 1.82, 95% CI 1.20-2.76). The polymorphism was associated with a higher risk of developing grade 3 (OR 1.84, 95% CI 1.00-3.36), multiple-tumor (OR 1.81, 95% CI 1.08-3.02), and large-tumor (OR 1.94, 95% CI 1.22-3.10) bladder cancers. These observations suggest that the TSP-1 -696 C/T polymorphism may contribute to bladder cancer susceptibility in the Chinese population.
