Potential organ donors with primary brain tumours: missed opportunities for donation and transplantation identified in Australian cohort study 2010-2015.

Donors with WHO-I/II PBT appear to have minimal risk of tumour transmission in solid organ transplantation; it is reassuring that no PBT transmission occurred. There is evidence of risk aversion to referrals with WHO-III/IV tumours. There exists opportunity to improve potential donor risk assessment at the time of referral using integrated data sets, and to increase organ donation and transplantation rates through greater utilization of PBT referrals.
