VEGFA and renal cell carcinoma: Compared with RCC patients who carried VEGF-A CTGC, CTGG, and ACAG haplotypes and had low urinary total arsenic (≤ 17 μg/L), patients who had high urinary total arsenic (>17 μg/L) and carried the VEGF-A ACGG haplotype had a significantly increased OR of recurrence of 7.21 (95% CI 1.61–32.31) after multivariate adjustment (Ptrend = 0.02).
