We analyzed in Spanish population the risk contribution and the prognostic significance for colorectal cancer (CRC) with five polymorphisms (rs20417, rs20426, rs5276, rs13306035 and rs4648298) located in the coding and regulatory regions of COX2.
To investigate possible association of FS with single nucleotide polymorphisms (SNPs) in prostaglandin-endoperoxide synthase-2 (prostaglandin G/H synthase-2; PTGS2/cyclooxygenase-2; COX2) gene involving in thermoregulatory pathway, eight SNPs, rs689465, rs689466, rs20417, rs13306038, rs201931599, rs689470, rs4648306 and rs4648308, along with 2 previously reported variations in IL1RN (86-bp VNTR) and IL10 (rs1900872) were genotyped and utilized for case-control association studies on 35 FS and 31 non-FS controls.

Our results indicate no strong association between three most frequent COX-2 SNPs rs689465 rs689466, rs20417 studied with breast cancer risk in the single locus analysis.
This meta-analysis showed that COX-2 rs20417 polymorphism was correlated with an increased risk of breast cancer in Caucasians, while rs689466 was associated with a decreased risk of breast cancer in Caucasians.
This meta-analysis showed that COX-2 rs20417 polymorphism was correlated with an increased risk of breast cancer in Caucasians, while rs689466 was associated with a decreased risk of breast cancer in Caucasians.
In conclusion, the present meta-analysis suggests that none of the most studied three SNPs (rs5275, rs20417, and rs5277) in the COX-2 gene is a conspicuous low-penetrant risk factor for developing breast cancer.
Here, we evaluate the impact of the four most common cyclooxygenase-2 gene polymorphisms (rs689465, rs689466, rs20417 and rs20417), in combination with obesity, on the risk of breast cancer progression in a cohort of Brazilian breast cancer patients (<i>N</i> = 1038).
COX-2-rs20417 CC genotype was significantly associated with increased risk of breast cancer when comparing to G allele [ORs were 1.231 (1.050-1.444) for CC vs. GG, P = 0.01, 1.223 (1.045-1.432) for CC vs. G carrier, P = 0.01].

We found no evidence that rs20417</span> alters prostate cancer</span> risk (odds</span> ratio (OR(CC & GC v GG)=1.05, 95% confidence interval (CI)=0.91-1.20).
The aim of this study was to investigate the association between the cyclooxygenase 2 (COX2) -765G>C (rs20417) polymorphism and prostate cancer (PC) risk using meta-analysis.

In a hospital-based case/control study, 195 subjects with PCa and 250 healthy controls were investigated for the association of COX-2 -765 G>C (rs20417) and +8473 T>C (rs5275) promoter polymorphism with PCa susceptibility using the polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method.

A secondary aim was to replicate the interaction of PTGS2 rs20417 (-765G to C) with aspirin use on coronary heart disease risk observed in the Atherosclerosis Risk in Communities Study (ARIC).
