Transplant of kidneys with small renal cell carcinoma in incompatible, heavily immunosuppressed recipients

Renal cell carcinoma (RCC) is considered a contraindication for transplant. However, an increasing number of cases of transplant kidneys with RCC have been reported with encouraging results. We present our experience of two cases of transplanting kidneys with small RCCs. Donors and recipients were aware of the presence and possible consequences of RCC in the transplanted kidney before transplantation. Cases were discussed in the multidisciplinary team meetings. Regular, 6–12 monthly follow-up of donors and recipients was carried out with ultrasonography and/or computed tomography to detect recurrence of RCC or new tumours in the recipients’ transplant kidneys or the donors’ native kidneys. The outcome was recorded. There were no suspicious masses in the any of the kidneys during the follow-up period. The transplant kidneys are functioning.
