Association Between Urothelial Carcinoma After Kidney Transplantation and Aristolochic Acid Exposure: The Potential Role of Aristolochic Acid in HRas and TP53 Gene Mutations

UC after kidney transplantation significantly correlated with AA exposure; however, there seemed to be no significant difference in mutations in exons 2 and 3 of the HRas gene and those in exons 5, 6, 7, and 8 of the TP53 gene in terms of tumor development, a result that is inconsistent with previous studies.
