Transmission of breast cancer by a single multiorgan donor to 4 transplant recipients

Abstract: We report 4 cases of breast cancer transmission to transplant recipients from a single organ donor that occurred years after donation. The diagnosis of breast cancer was occult at the time of donation. All of the recipients developed a histologically similar type of breast cancer within 16 months to 6 years after transplantation. Three out of 4 recipients died as a result of widely metastasized disease. One of the recipients survived after transplant nephrectomy followed by cessation of immunosuppression and c… Show more

“…Cancer cells do not usually transmit between individuals. No human examples of transmissible cancers are known apart from rare iatrogenic cases during surgery and transplantation or materno-fetal transmission ( Isoda et al., 2009 , Matser et al., 2018 , Metzger and Goff, 2016 ). Accordingly, horizontal transmission is not considered a hallmark of cancer ( Hanahan and Weinberg, 2011 ).…”

“…Previous study suggested that timely removal of allograft might be bene cial to prevent the development of metastasis 2 . In order to prevent transmission, it should be considered in all recipients after noti cation of cancer transmission in one recipient from a multiorgan donor.…”

“…The persistent organ shortage requires the maximum utilization of all available donors, including those with tumors, that may lead to donor-derived malignancy [1][2][3] . There is a consensus that whether to use donor organs with tumors depends on risk levels of tumor transmission.…”

“…Pommier et al [171] have recently reported that patients and mice with pancreatic ductal adenocarcinoma contained single quiescent DTCs lacking MHC-I expression, which enabled them to escape immunity and establish latent metastases. Four cases of breast cancer transmission to immunosuppressed transplant recipients from a single, clinically healthy donor have been recently described [172] . The latency time to metastasis formation ranged from 16 months to 6 years, and transmissions did not occur in a patient that discontinued immunosuppression.…”

“…The latency time to metastasis formation ranged from 16 months to 6 years, and transmissions did not occur in a patient that discontinued immunosuppression. This unintentional situation suggested that donor tissues harbored DTCs, which persisted in a latent state because of immune control, while the immunosuppression of the recipient allowed the DTCs to resume growth [172] . Once cells have escaped immunosurveillance it is unlikely that they can re-enter a second state of immunological dormancy, because the mechanisms that eluded immunosurveillance are generally part of the genetic or epigenetic tumor clonal evolution and therefore irreversible [59,91] .…”
