摘要
Single nucleotide polymorphism (SNP) rs710521[A], located near TP63 on chromosome 3q28, was identified to be significantly associated with increased bladder cancer risk. To investigate the association of rs710521[A] and bladder cancer by new data and by meta-analysis including all published data, rs710521 was studied in 1,425 bladder cancer cases and 1,740 controls that had not been included in previous studies. Blood samples were collected from 1995 to 2010 in Germany ( n = 948/1,258), Hungary ( n = 262/65), Venezuela ( n = 112/190) and Pakistan ( n = 103/227) supplemented by a meta-analysis of 5,695 cases and 40,187 controls. Detection of a A/G substitution (rs710521) on chromosome 3q28, position 191128627 was done via fast real-time polymerase chain reaction (rt–PCR). Rs710521[A] is associated with increased risk in the unadjusted analysis (OR = 1.21; 95% Cl = 1.04–1.40; P = 0.011) and in the recessive model adjusted for age, gender, smoking habits and ethnicity (OR = 1.23; 95% Cl = 1.05–1.44; P = 0.010). No difference between individuals occupationally exposed versus not occupationally exposed to urinary bladder carcinogens was observed concerning the relevance of rs710521[A]. Similarly, rs710521[A] did not confer different susceptibility in smokers and non-smokers. Performing a meta-analysis of 5,695 cases and 40,187 controls including all published studies on rs710521, a convincing association with bladder cancer risk was obtained (OR = 1.18; 95% Cl = 1.12–1.25; P < 0.0001). However, the odds ratio is relatively small.
