Background: We aimed to examine the relationships between the angiotensinogen (AGT) and vascular endothelial growth factor (VEGF) gene single nucleotide polymorphisms and susceptibility to bladder and kidney cancers.
Methods: A 1:1 paired case-control study was conducted, which included 143 newly diagnosed kidney cancer cases, 182 newly diagnosed bladder cancer cases, and healthy subjects in the same period collected from two hospitals. Medical records and a questionnaire were used to obtain relevant information. Genotypes were determined by improved multiple ligase detection reaction (iMLDR) and VEGF serum expression levels were detected by enzyme-linked immunosorbent assays (ELISAs).
Results: The VEGF gene/genotype frequencies of rs833061 and rs1570360 were statistically different among various pathological grades of kidney cancer, while the AGT rs699 gene/genotype frequencies were statistically different among various pathological types of bladder cancer. In kidney cancer, rs699 was associated with smoking, drinking, and hair coloring, while in bladder cancer, rs699, rs1570360, rs3025039, and rs833061 were associated with smoking, drinking, hair coloring, exercise, and urine holding.
Conclusions: This work will help identify biomarkers that can predict the early metastasis and recurrence of kidney or bladder cancer, as well as help improve patient survival rates by predicting their susceptibility.
Significance: This work will provide reference for the prevention and treatment of kidney and bladder cancers.
