BACKGROUND: Liver transplantation (LT) has emerged as a potential treatment option for selected patients with colorectal liver metastases (CRLM), but existing meta-analyses are limited by heterogeneous populations and mixed treatment modalities.
METHODS: A systematic review and single-arm meta-analysis were conducted in accordance with PRISMA guidelines. Studies reporting outcomes following LT for CRLM were included. Primary outcomes were overall survival (OS) and progression-free survival (PFS) at predefined time points. Secondary outcomes included adverse events. Pooled proportions were calculated using random-effects models with logit transformation and Hartung-Knapp adjustment. Heterogeneity was assessed using the I² statistic.
RESULTS: Four prospective studies (1 RCT, 3 prospective cohorts) comprising 118 patients were included. Studies were conducted in Norway (SECA-I, n = 21; SECA-II, n = 15), the United Kingdom (n = 50), and a European multicentre RCT (TransMet, n = 32). Median age ranged from 55 to 58 years; all patients had liver-only metastases with resected primary tumors and had received pre-transplant chemotherapy. The pooled 3-year OS was 69% (95% CI, 52-82%; I² = 0.0%), and the pooled 5-year OS was 62% (95% CI, 36-83%; I² = 14.6%). The pooled 3-year PFS was 33% (95% CI, 7-76%), with substantial heterogeneity (I² = 62.8%). The pooled incidence of adverse events was 41% (95% CI, 25-60%; I² = 0.0%). Sensitivity analyses confirmed the robustness of pooled estimates. The retrospective literature also supported the finding that LT can achieve meaningful long-term survival in carefully selected patients.
CONCLUSIONS: In carefully selected patients with CRLM, LT is associated with durable long-term survival and an acceptable safety profile, supporting further prospective evaluation and refinement of selection criteria.
