Abstract:
We retrospectively investigated germline polymorphisms in angiogenesis pathway genes (14 SNPs) and their correlation to clinical outcome (progression free survival and overall survival) in 128 patients with unresectable-advanced gastric carcinoma (AGC) treated with first-line chemotherapy. Our analysis revealed that Endostatin +4349 G>A polymorphism exhibited a worse progression free survival (PFS) and overall survival (OS) compared with the GG genotype. Significant OS difference was also observed in the endothelial nitric oxide synthase (eNOS)-786 T>C polymorphism. Hence, common germline variants in Endostatin and eNOS genes have predictive significance for clinical outcome and survivality in AGC patients treated with first-line chemotherapy.
