Impact of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor (VEGFR) single nucleotide polymorphisms on outcome in gastroenteropancreatic neuroendocrine neoplasms

Abstract: Angiogenesis represents a key event in cancer development, leading to local invasion e metastatization, and might be considered a basic feature in gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) with a high expression of angiogenic molecules. We aimed to analyze the prognostic and predictive role of angiogenic factors in GEP-NENs through the analysis of single nucleotide polymorphisms (SNPs) of VEGF-A, VEGFR2 and VEGFR3. The genomic DNA of 58 consecutive patients with GEP-NENs treated at our Institu… Show more

“…There was no significant association of the expression levels of VEGFR 1-3 and overall survival. Nonetheless, these results are in line with previous studies on other gastrointestinal malignancies [ 35 , 36 ]. This might in part be explained by the fact that well- to moderately differentiated GEP-NENs have a favorable overall survival even in the presence of distant metastases and that there was no significant correlation between tumor grading and the expression of VEGFRs.…”

“…In total, 66 tagSNPs (27 from KDR gene, 32 from NRP-1 gene and 7 from PDGFβ) were selected, however due to financial constraints, 10 SNPs (rs7692791, rs6838752, rs2034965, rs1531290, rs13109660 from KDR, rs2070296, rs2804495, rs2065364 from NRP-1, and rs4821877, and rs9622978 from PDGFβ) were randomly selected from the tagSNPs. In addition, five disease-associated SNPs (rs1870377 and rs2305948 from KDR, rs6554162 and rs1800812 from PDGFRα, and rs2302273 from PDGFRβ) were selected according to their use in previous literature (1924). Finally, the 15 SNPs (Table SI) of KDR rs7692791, rs2305948, rs6838752, rs2034965, rs1531290, rs13109660 and rs1870377, of NRP-1 rs2070296, rs2804495 and rs2065364, of PDGFβ rs4821877 and rs9622978, of PDGFRα rs6554162 and rs1800812, and of PDGFRβ rs2302273, were obtained from the SNP database of the NCBI ().…”

“…It was also observed that the expressions of VEGFR-2 (p = 0.032) and VEGFR-3 (p = 0.034) receptors in the lymph nodes of CRC patients were significantly related to cancer recurrence. Although scarce, some literature data endorse these findings, since they assign to the presence of angiogenic cytokine receptors an increased risk of relapse of several types of cancer [24][25][26]. In view of this finding, it may be important to implement a tighter follow-up plan for patients with positive expression of VEGFR-2 and VEGFR-3 receptors in the resected lymph nodes in order to make an earlier detection of cancer recurrence.…”
