Transplantation for metastatic liver disease

Area of Science:

• Hepatology
• Surgical Oncology
• Gastroenterology

Background:

• Liver metastases are common, especially from gastrointestinal cancers.
• Liver transplantation is a potential, though debated, treatment for specific liver metastases.
• Previous outcomes for colorectal liver metastases were poor, but recent studies show promise.

Purpose of the Study:

• To critically review current knowledge on liver transplantation for neuroendocrine and colorectal liver metastases.
• To identify gaps in evidence and suggest future research directions.
• To evaluate the efficacy and role of liver transplantation in managing liver metastases.

Main Methods:

• Review of existing literature and prospective studies.
• Analysis of patient selection criteria and treatment outcomes.
• Comparison of liver transplantation with other treatment modalities like hepatectomy and chemotherapy.

Main Results:

• Meticulous patient selection in neuroendocrine liver metastases is linked to excellent long-term survival.
• A pilot study for unresectable colorectal liver metastases showed a 5-year survival rate of 60%.
• Ongoing trials aim to compare liver transplantation benefits against palliative chemotherapy.

Conclusions:

• Liver transplantation is a viable option for selected patients with neuroendocrine and colorectal liver metastases.
• Further research is needed to optimize neoadjuvant/adjuvant therapies and procedural timing.
• Defining the role of transplantation versus hepatectomy requires continued investigation.
