BACKGROUND: Current success in transplant oncology for select liver tumors, such as hepatocellular carcinoma, has ignited international interest in liver transplantation (LT) as a therapeutic option for nonresectable colorectal liver metastases (CRLM). In the United States, the CRLM LT experience is limited to reports from a handful of centers. This study was designed to summarize donor, recipient, and transplant center characteristics and posttransplant outcomes for the indication of CRLM.
METHODS: Adult, primary LT patients listed between December 2017 and March 2022 were identified by using United Network Organ Sharing database. LT for CRLM was identified from variables: "DIAG_OSTXT"; "DGN_OSTXT_TCR"; "DGN2_OSTXT_TCR"; and "MALIG_TY_OSTXT."
RESULTS: During this study period, 64 patients were listed, and 46 received LT for CRLM in 15 centers. Of 46 patients who underwent LT for CRLM, 26 patients (56.5%) received LTs using living donor LT (LDLT), and 20 patients received LT using deceased donor (DDLT) (43.5%). The median laboratory MELD-Na score at the time of listing was statistically similar between the LDLT and DDLT groups (8 vs. 9, P = 0.14). This persisted at the time of LT (8 vs. 12, P = 0.06). The 1-, 2-, and 3-year, disease-free, survival rates were 75.1, 53.7, and 53.7%. Overall survival rates were 89.0, 60.4, and 60.4%, respectively.
CONCLUSIONS: This first comprehensive U.S. analysis of LT for CRLM suggests a burgeoning interest in high-volume U.S. transplant centers. Strategies to optimize patient selection are limited by the scarce oncologic history provided in UNOS data, warranting a separate registry to study LT in CRLM.
