Nephrotoxicity after PRRT — still a serious clinical problem? Renal toxicity after peptide receptor radionuclide therapy with 90Y-DOTATATE and 90Y/177Lu-DOTATATE
open access
Abstract
Material and methods: 53 patients, with disseminated neuroendocrine tumours (NET), received 3–5 cycles of up to a maximum 7.4 GBq/m2 calculated dose of 90Y-DOTATATE (n = 25) and 90Y/177Lu-DOTATATE (n = 28). Creatinine levels were measured and glomerular filtration rates (GFR) were calculated. A mixed amino acid infusion was used for nephroprotection.
Results: Patients treated with 90Y-DOTATATE had a mean creatinine level of 0.77 ± 0.19 mg/dL and a mean GFR (mL/min/1.73 m2) of 103.6 ± 30.8. Patients treated with 90Y/177Lu-DOTATATE had a mean creatinine level of 0.92 ± 0.33 mg/dL and a mean GFR of 84.7 ± 26.3. In the follow up, among patients treated with 90Y-DOTATATE and 90Y/177Lu-DOTATATE, the mean GFR level at 12 months was 101.2 ± 31.3 v. 83.9 ± 25.2, at 24 months 80.2 ± 32.7 v. 77.2 ± 31.1, at 36 months 78.9 ± 42.1 v. 67.5 ± 9.7, and 48 months 59.7 ± 15.2 v. 72.6 ± 11.2. The mean yearly decrease in GFR was 4.5 mL in all treated patients; for patients treated with 90Y-DOTATATE and 90Y/177Lu-DOTATATE it was 6.8 v. 3.0, respectively.
Conclusions: 90Y/177Lu-DOTATATE treatment induced statistically significantly less change in kidney function compared to 90Y-DOTATATE.
