Title: Association of interleukin-8 (IL-8 or CXCL8) -251T/A and CXCR2 +1208C/T gene polymorphisms with breast cancer | ||
Author: E. KAMALI-SARVESTANI, M.R. ALIPARASTI, S. ATEFI | ||
Abstract: A case-control study involving 257 breast cancer patients with invasive ductal carcinoma and 233 healthy women
was carried out to explore if the IL-8 -251T/A polymorphism and the CXCR2 +1208 C/T polymorphism have a role in
breast cancer susceptibility. Genotypic analysis showed an increased frequency of high producer IL-8 -251AA genotype
(p=0.016) in the patient group as compared to controls while CXCR2 +1208 C/T polymorphism did not show any
differences between studied groups. However, in contrast to IL-8 -251 polymorphism, the percentage of CXCR2 +1208
TT genotype was significantly lower in patients with NPI≤3.4 compared to NPI>3.4 (2% and 12%, respectively;
p=0.03). Also, ER- tumors showed an approximately significant higher CXCR2 +1208 TT genotype compared to ER+
tumors (18.6% and 7.1%, respectively; p=0.07). In conclusion, IL-8 -251T/A polymorphism is associated with
development of invasive ductal carcinoma type of breast cancer while CXCR2 +1208C/T polymorphism may affect
the disease progression. |
