This study is a single center, open-label study available to male and female adults with CRC LM that are deemed to be unresectable and who are receiving standard of care chemotherapy. Participants will be worked up for LDLT while continuing to receive chemotherapy and, if deemed eligible for surgery, will stop chemotherapy 4 weeks prior to receiving a living donor transplant. Recipients will be followed for 5 years (for safety, survival and disease recurrence for purposes of study data collection). They will continue to be monitored for safety, survival and disease recurrence indefinitely as part of University of Wisconsin (UW) Health's Organ Transplant Program care standards. Living liver donors will be followed for 2 years after transplant surgery for safety monitoring as part of this study.~Recruitment will be done in two stages. The first stage will be a pilot study of 5 recipients to determine if LDLT is a suitable treatment for patients with non-resectable LM. If, after 3 years of follow-up, the overall survival is greater than 60%, stage two recruitment will commence. Thus, an interim analysis will be done for the first 5 recipients prior to requiring a larger number of subjects. Stage two recruitment will focus on accruing a total of up to 20 additional recipients to be analyzed.~The control group will consist of any potential recipients that sign the informed consent and are enrolled in the study but do not undergo LDLT due to a lack of an eligible donor. These participants will be referred back to their medical oncologists to receive standard of care chemotherapy, and will continue to be followed as the control group.~Patients who sign the informed consent and are enrolled in the study with an eligible live donor but do not undergo LDLT due to disease progression or a contraindication is established for undergoing LT (exclusion criteria) will also be referred back to their medical oncologists to receive standard of care chemotherapy. This group will be followed as part of the intent to treat cohort.
This study will test the safety and efficacy of living donor liver transplant after standard-of-care chemotherapy for participants with non-resectable liver metastases (LM) from colorectal cancer. 25 donor-recipient pairs will be enrolled (50 participants). Donors will be on study for 2 years and recipients will be on study for up to 5 years.
