Background: Hepatic malignancies are a major global health burden, with rising incidence, high mortality, and frequent diagnosis at advanced or unresectable stages. Although surgical resection, locoregional therapies, and systemic treatments have improved outcomes, many patients remain ineligible for curative strategies because of tumor burden, anatomical constraints, or liver dysfunction. Liver transplantation (LT) has therefore evolved from a treatment limited to selected hepatocellular carcinoma (HCC) cases within strict morphological criteria to a broader oncologic option guided by tumor biology and treatment response. This review provides an updated overview of the expanding role of LT in hepatic malignancies and the transition toward precision transplant oncology. Methods: We conducted a narrative review of current evidence on LT in HCC, cholangiocarcinoma (CCA), and colorectal liver metastases (CRLM), focusing on candidate selection, neoadjuvant strategies, molecular profiling, immunological aspects, and future perspectives. Results: In HCC, expanded criteria and bridging/downstaging strategies, including immunotherapy, have increased transplant eligibility, although concerns remain regarding rejection risk and post-transplant management. In CCA, especially perihilar disease, standardized neoadjuvant protocols followed by LT have achieved encouraging long-term survival in highly selected patients, whereas intrahepatic CCA remains investigational within prospective biomarker-driven studies. In CRLM, once considered an absolute contraindication, recent evidence supports LT in selected patients with liver-confined and biologically favorable disease, emphasizing the importance of tumor kinetics, molecular features, and response to systemic therapy. Conclusions: Integration of molecular oncology, immunology, and advanced therapies is redefining LT indications for hepatic malignancies. Future progress will depend on biomarker-driven selection, precision medicine, and multidisciplinary decision-making to optimize outcomes while addressing ethical challenges in organ allocation.

Abstract
Background: Hepatic malignancies are a major global health burden, with rising incidence, high mortality, and frequent diagnosis at advanced or unresectable stages. Although surgical resection, locoregional therapies, and systemic treatments have improved outcomes, many patients remain ineligible for curative strategies because of tumor burden, anatomical constraints, or liver dysfunction. Liver transplantation (LT) has therefore evolved from a treatment limited to selected hepatocellular carcinoma (HCC) cases within strict morphological criteria to a broader oncologic option guided by tumor biology and treatment response. This review provides an updated overview of the expanding role of LT in hepatic malignancies and the transition toward precision transplant oncology. Methods: We conducted a narrative review of current evidence on LT in HCC, cholangiocarcinoma (CCA), and colorectal liver metastases (CRLM), focusing on candidate selection, neoadjuvant strategies, molecular profiling, immunological aspects, and future perspectives. Results: In HCC, expanded criteria and bridging/downstaging strategies, including immunotherapy, have increased transplant eligibility, although concerns remain regarding rejection risk and post-transplant management. In CCA, especially perihilar disease, standardized neoadjuvant protocols followed by LT have achieved encouraging long-term survival in highly selected patients, whereas intrahepatic CCA remains investigational within prospective biomarker-driven studies. In CRLM, once considered an absolute contraindication, recent evidence supports LT in selected patients with liver-confined and biologically favorable disease, emphasizing the importance of tumor kinetics, molecular features, and response to systemic therapy. Conclusions: Integration of molecular oncology, immunology, and advanced therapies is redefining LT indications for hepatic malignancies.
