Thyroid cancer patients are treated with up to 9.9 GBq of 131I to ablate remnant thyroid tissue and/or any functioning metastases that may be present. Radioiodine therapy is repeated as often as required. However, only a small fraction of the 131I is taken up by remnant thyroid and metastases, the remainder being eliminated by the kidneys, which are therefore subject to irradiation. External radiation therapy to the kidneys is known to lead to nephritis and albuminuria. The study included 113 patients treated with one to four doses of 131I (1.1-9.9 GBq each dose) and followed up 1 month to more than 8 years later. Spot samples of urine were collected and microalbuminuria measured by in-house radioimmunoassay. Twelve patients had elevated levels (normal range up to 34 micrograms ml-1), but their clinical history revealed such predisposing factors as diabetes and/or hypertension and proteinuria before therapy commenced. The remaining patients had normoalbuminuria. Grouping the patients based on the total dose of 131I administered resulted in a median microalbuminuria of 2.4-12.9 micrograms ml-1. Hence, this study showed that the dose of 131I normally used in treating thyroid cancer does not increase microalbuminuria to any significant extent.
