Regarding immunosuppressive therapy at discharge, only interleukin-2 receptor antibody and T-cell-depleting antibody levels in the RCC group differed significantly from those of the other groups, while the mammalian target of rapamycin inhibitor (mTOR), known for its antioncogenic effects, was used least in patients with RCC-induced ESRD (Table 3). This evidence concerns the gene MTOR and renal cell carcinoma.
