This study found 17 of 181 kidneys from patients who underwent partial or radical nephrectomy for stage I RCC to have tumors less than 3 cm in diameter and thereby possibly suitable for transplantation. This was a survey study; no transplants were performed. (Council of Europe, 2022): To provide valid histological staging, complete tumour resection (R0) is required for acceptance of all organs; additionally, tumour-free margins are a prerequisite for transplant of the affected kidney. Paraffin section is superior to frozen section for the assessment of such biopsies. The contralateral kidney should always be examined for synchronous RCC (5 % of patients). RCC < 1 cm (stage T1a AJCC 8th edn) and WHO/ISUP grade I/II (Fuhrman grade I/II) can be considered minimal-risk for transmission; RCC 1-4 cm (stage T1a AJCC 8th edn) and WHO/ISUP grade I/II (Fuhrman grade I/II) are considered low-risk; RCC > 4-7 cm (stage T1b AJCC 8th edn) and WHO/ISUP grade I/II (Fuhrman grade I/II) are considered intermediate-risk; RCC > 7 cm (stage T2 AJCC 8th edn) and WHO/ISUP grade I/II (Fuhrman grade I/II) are considered high-risk; RCC with extension beyond the kidney (stages T3/T4 AJCC 8th edn) is considered a contraindication to transplant; All RCC with WHO/ISUP grade III/IV (Fuhrman grade III/IV) are considered high-risk for transmission; Contralateral kidneys and other organs that are un¬involved in carcinoma are considered to represent minimal risk for transplantation when the RCC in the involved kidney is 4 cm or less and WHO/ISUP grade I-II. In all cases, follow-up surveillance is desirable. RCC in the donor history: The transmission risk of treated RCC depends on the histological type of tumour [159] and its recurrence-free follow-up period. In general, in the first 5 years after initial diagnosis, risk categories correspond to those stated above (RCC diagnosed during donor procurement) if there is no suspicion of tumour recurrence in the donor. After this time, the risk of advanced stages may decrease.

Expert comments for publication: 
The authors found approximately 10 of kidneys resected for stage I RCC to be possibly suitable for transplantation. This is a consideration, although others have argued against performing a total nephrectomy if a partial nephrectomy will suffice, given the possible long-term risk to the potential donor if a second carcinoma were to arise in the contralateral kidney. Most recent urology guidelines recommend nephron sparing partial nephrectomy in such small stage I RCC. Therefore, the number of cases may not increase.
