We analyzed two single nucleotide polymorphisms of IL-10 gene at G-1082A (rs 1800896) and C-819T (rs 3021097) in 214 histologically confirmed UBC patients and 385 matched controls by allele-specific polymerase chain reaction (AS-PCR).
Analyses of the data identified TGF-beta codon 25 GG (92.85% vs. 64.44%, p=0.04, OR=7.17), IL-4 -1098 GG (16.6% vs. 0.0%, p=0.05, OR=18.33), IL-10 -1082 GG (28.5% vs. 6.8%, p=0.05, OR=5.47), and IL-10 -1082 GCC/GCC (28.57% vs. 4.5%, p=0.025, OR=8.4) polymorphisms as risk factors for progression of bladder cancer.
