Purpose of review: Immune checkpoint inhibitors (ICIs) have transformed the treatment landscape in advanced hepatocellular carcinoma and increasingly are being evaluated in earlier stage disease. Herein we explore the role of ICIs pre-liver transplant for liver cancers.
Recent findings: Given the high response rates with combination approaches including locoregional treatments, more patients with liver confined disease, without vascular invasion, who have received ICIs are now being rendered eligible for potential liver transplant. This opportunity to expand the population who may benefit from liver transplant has also come with challenges recognizing the global shortage of organs. Post-liver transplant immunosuppression potentially competes with the immune-stimulating effects of ICIs and graft rejection has been a concern. ICIs may provide an opportunity to maintain patients on the waiting list but an understanding of who is likely to benefit is needed, to circumvent possible toxicities. In addition, ICIs are now considered standard of care, in combination with chemotherapy, for advanced cholangiocarcinoma, where the role of liver transplant is evolving.
Summary: As the eligibility criteria globally for liver transplant in the setting of malignancy continues to expand, the integration of ICIs becomes increasingly important.
