Background Angiogenesis play a critical role in the development and progression of tumors in solid tumors. Vascular endothelial growth factor (VEGF) is one of the most important endothelial cell mitogen which plays a critical role in normal physiological and tumor angiogenesis. Objectives The objective of this case-control study was to investigate the association of VEGF-2578C/A, -2549 I/D, and -460T/C promoter polymorphisms with esophageal cancer risk in North-West Indians. Methods In this study, 200 sporadic esophageal cancer patients and 200 healthy, unrelated, age and gender matched controls were analyzed. The genomic DNA was extracted from blood samples using phenol chloroform method. Genotyping of VEGF- 2549I/D polymorphism was carried out by direct polymerase chain reaction (PCR) whereas VEGF -2578C/A and VEGF-460T/C) polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results AA genotype (p = 0.005) and A allele (p = 0.005) VEGF -2578 C/A, II genotype (p = 0.011) and I allele (p = 0.012) of VEGF − 2549 I/D and CC genotype (p = 0.013) and C allele of VEGF-460T/C polymorphisms were significantly associated with increased risk of esophageal cancer. Stratification of data on the basis of gender showed that VEGF -2578 AA genotype (p = 0.001) and A allele (p = 0.001); VEGF -2549 II genotype (p = 0.002) and I allele (p = 0.002) and VEGF- 460CC genotype (p = 0.001) and C allele (p = 0.002) was significantly associated with increased risk of esophageal cancer in female group. Haplotype analysis revealed that A-2578 I− 2549 C− 460 haplotype was significantly associated with increased risk for esophageal cancer in total samples (p = 0.008) as well as in female group (p = 0.001). Conclusions The results of present study indicate that VEGF -2578C/A, − 2549I/D and -460T/C polymorphisms were significantly associated with increased risk of esophageal cancer in North-West Indians.
