Association of interleukin6 rs1800796 gene polymorphism and serum level with bladder cancer in Egyptian population.

BACKGROUND

Urinary bladder cancer (UBC)is a common tumor of the urinary tract.

OBJECTIVES

To assess the diagnostic significance of IL6 rs1800796 gene polymorphism and IL6 serum level among Egyptian patients with UBC.

DESIGN AND

METHODS

One hundred patients with UBC were selected from the Mansoura Urology and Nephrology Center, in addition to 100 healthy control subjects; using PCR and ELISA techniques for IL6 detection.

RESULTS

The rs1800796 GC, CC genotypes, and C allele were significantly more prevalent in the cases with bladder cancer compared to the healthy group (p < 0.001, = 0.021, < 0.001 respectively). There was a clear association between elevated levels of IL6 and bladder cancer versus the control group (median = 4.2, 0.89 respectively, p < 0.001). Serum IL6 levels showed significantly higher levels in patients carrying CC, followed by GC then GG genotypes. No significant association was found between IL6 rs1800796 gene polymorphism or serum level with demographic or laboratory data.

CONCLUSION

It is suggested that there is a clear link between elevated IL6 levels as well as IL6 rs1800796 gene polymorphism with bladder cancer, suggesting their potential utility as biomarkers for the disease.
