Case series: Donor(s) Renal cell, cervical carcinoma (without transmission) (1998)

Most recent risk assessment for uterine and cervical cancer (Council of Europe, 2022): The presence of invasive uterus or cervix cancers is considered an unacceptable risk for organ donation. Uterus or uterine cervix cancer in the donor history: After a disease-free interval > 5 years, the transmission risk of invasive uterus and cervix cancers will depend on the probability of cure and has to be assessed individually before accepting the potential donor; no specific recommendations are available from the literature. Most recent risk assessment for renal cell carcinoma (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 ed) 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 ed) and WHO/ISUP grade I/II (Fuhrman grade I/II) are considered low-risk; RCC > 4-7 cm (stage T1b AJCC 8th ed) and WHO/ISUP grade I/II (Fuhrman grade I/II) are considered intermediate-risk; RCC > 7 cm (stage T2 AJCC 8th ed) 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 ed) 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 un­involved 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 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.
