Abstract
Background: One of the main causes of cancer-related deaths is breast cancer. Fascin-1(FSCN1) is an actin-binding protein that is present in the mesenchymal, neuronal, and endothelial cells of mammals. Patients with breast cancer have been found to have FSCN1 overexpression. CD44 is crucial for the development, invasion, and tumour spread. Therefore, we aimed to investigate the role of FSCN1&CD44 gene polymorphisms in breast cancer (BC) risk and prognosis. Materials & Methods: A total of 96 BC patients and 50 controls were included in the case-control study for risk prediction. We examined the association between The SNPs on FSCN1(rs3801004) and CD44(rs353639) and BC susceptibility and clinicopathological features using a real-time PCR in a cohort of the Egyptian population. Results: A significant association of both SNPs on FSCN1(rs3801004)C allele and CD44(rs353639)A allele and BC susceptibility(adjusted OR=4.38,95%CI:2.6–7.4,p<0.001, and adjusted OR=4.44,95%CI:2.65–7.44,p <0.001,respectively). Moreover, CC genotype in FSCN1(rs3801004) were likely to progress to developing G2&G3 and N2&N3 and stage II & stage IV, according to the TNM staging and GG+GC genotypes increased within individuals who had a positive family history of BC. Individuals who carry at least one A allele for CD44rs353639 were likely to progress developing N2 according to the TNM in BC patients. Conclusions: These findings suggest that both SNPs on FSCN1 (rs3801004) and CD44 (rs353639) affected BC susceptibility. FSCN1 (rs3801004) genetic variants may have a significant effect on BC prognosis. However, CD44 (rs353639) affected lymph node invasions in BC patients.
