Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim of the study is to see whether selected patients with isolated liver metastases may benefit from liver transplantation.

Liver transplantation is an intervention that participants receive as part of this study.
The liver transplant surgery itself usually takes around 4 to 6 hours, depending on the complexity of the case. During the procedure, the diseased liver is removed, and a healthy donor liver is transplanted. Surgery consist in liver transplantation, removal of the receipient liver containing colorectal liver metastases with a liver from a living donor or deceased donor.
After surgery, the patient is transferred to the Intensive Care Unit (ICU) for close monitoring, typically for 1-2 days, to ensure the new liver is functioning well and to manage pain or any complications. The total hospital stay is generally around 7 to 10 days, during which the patient will receive post-operative care, medication to prevent rejection, and guidance on recovery. After discharge, regular follow-up appointments and blood tests are essential to monitor the liver function and overall recovery.

Surgery is performed by liver transplant surgeons at RPA hospital. Liver transplant is a standard procedure here in Australia and the rest of world. No specific pre-post sugery requirements.

Statistical methods / analysis
The cumulative incidence of recurrence and Cancer-specific death were evaluated by competing risk analysis.
The standard Cox proportional hazard model will be used when there are no competing events, to model cause-specific hazards as proposed by Prentice et al.

In order to account for the impact of competing risks, we will use the subdistribution hazard model approach proposed by Fine and Gray. This approach uses cumulative incidence function to accurately estimate marginal probability of an event in the presence of competing events.
