About this study

Official title: Efficacy of the RAPID Procedure (Resection and Partial Liver Transplantation With Delayed Total Hepatectomy) for Unresectable Colorectal Liver Metastases: A Prospective Clinical Study

The goal of this clinical trial is to learn if the RAPID procedure works to treat colorectal cancer that has spread to the liver and cannot be removed by surgery. It will also learn about the safety of the procedure. The main questions it aims to answer are:

  1. How many participants are alive without the cancer progressing or returning 2 years after the first-stage surgery?
  2. How many participants complete the second-stage surgery, and how quickly does the liver graft grow between the two stages?
  3. What medical problems do participants have around the time of surgery, including serious complications?

Participants will:

  1. Undergo the first-stage surgery: removal of the left part of the liver and implantation of a small liver graft, with the right portal vein tied off to help the graft grow;
  2. Have blood tests and ultrasound checks after surgery, and regular CT or MRI scans to measure graft growth; (4) Undergo the second-stage surgery to remove the remaining diseased liver once the graft has grown enough (5) Visit the clinic every 3 months for up to 2 years after the second-stage surgery for checkups, imaging, and blood tests to see if the cancer has returned
Read the detailed description

This is a prospective clinical trial evaluating the RAPID procedure (Resection and Partial Liver Transplantation with Delayed Total Hepatectomy) in patients with unresectable colorectal liver metastases (uCRLM).

Stage 1 is performed on Day 0: partial hepatectomy is carried out to remove the tumor-bearing portion of the liver, preserving the remaining native liver as temporary metabolic support. A small-for-size graft is implanted orthotopically. The portal vein supplying the preserved native liver is ligated to redirect portal flow to the graft, while the hepatic artery supplying the preserved native liver is preserved.

Interstage monitoring begins on postoperative Day 1. Liver function (TBIL, INR, ALT, AST) and graft blood flow (Doppler ultrasound) are assessed. Graft volume is measured by CT/MRI volumetry on postoperative Days 7 and 14, and every 7 days thereafter. The criteria for proceeding to Stage 2 (all must be met) are: graft GRWR ≥0.8%, and multidisciplinary team (MDT) confirmation that Stage 2 surgery can proceed. The first formal assessment is on postoperative Day 7.

Stage 2 is performed once the criteria are met: the remnant native liver is removed, and the graft is preserved.

Postoperative follow-up continues for up to 2 years after Stage 2 (with exploratory extension to 5 years), with visits every 3 months. Assessments include history and physical examination, ECOG status, liver function, CEA/CA19-9, contrast-enhanced CT of the chest and abdomen. Tumor progression or recurrence is adjudicated by an independent imaging reviewer. The primary endpoint is the 2-year tumor event-free survival rate, defined as the time from Stage 1 surgery to tumor progression, recurrence, or death from any cause, whichever occurs first.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RAPID ProcedureProcedure or surgery

    Two-stage surgical procedure combining the principles of ALPPS with auxiliary partial liver transplantation. Stage 1 (Day 0): partial hepatectomy to remove the tumor-bearing liver portion, orthotopic implantation of a small-for-size graft (living donor left lateral segments or split deceased-donor left lateral segments), and ligation of the portal vein supplying the preserved native liver; the corresponding hepatic artery is preserved. Interstage monitoring includes liver function tests, Doppler ultrasound, and CT/MRI volumetry. Stage 2: completion hepatectomy of the remnant native liver once the graft has achieved adequate volume and function.

RAPID ProcedureExperimentalAll enrolled participants receive the RAPID procedure, a two-stage surgical intervention. Stage 1: partial hepatectomy to remove the tumor-bearing portion of the liver, preserving the remaining native liver as temporary metabolic support; orthotopic implantation of a small-for-size liver graft; ligation of the portal vein supplying the preserved native liver to redirect portal flow to the graft, with preservation of the hepatic artery supplying the preserved native liver. Stage 2: completion hepatectomy to remove the remnant native liver after adequate graft hypertrophy (graft GRWR ≥0.8% and MDT confirmation).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 2-Year Tumor Event-Free Survival Rate

    Proportion of participants alive and free of tumor progression or recurrence at 2 years after Stage 1 surgery. A tumor event is defined as tumor progression or recurrence confirmed by imaging (CT/MRI/PET-CT) according to RECIST 1.1 or by pathology, or death from any cause, whichever occurs first. Participants who fail to complete Stage 2 surgery are counted as having an event from the date of Stage 2 failure, regardless of whether tumor progression has occurred. Participants last known to be alive and event-free are censored at the date of last follow-up.

    Measured: From Stage 1 surgery to tumor progression, recurrence, or death from any cause, assessed up to 2 years after Stage 1 surgery

Secondary outcomes (2)
  1. Incidence of Major Perioperative Complications (Clavien-Dindo Grade ≥IIIa)

    Proportion of participants experiencing Clavien-Dindo grade ≥IIIa complications from Stage 1 surgery through 90 days after Stage 2 surgery. Grade IIIa indicates complications requiring surgical, endoscopic, or radiological intervention without general anesthesia; grade IIIb requires intervention under general anesthesia; grade IV indicates life-threatening organ dysfunction requiring ICU management; grade V indicates death. Complications are recorded by type (e.g., primary graft non-function, small-for-size syndrome, biliary complications, vascular complications, bleeding, infection, renal failure requiring replacement therapy, respiratory failure requiring mechanical ventilation).

    Measured: From Stage 1 surgery through 90 days after Stage 2 surgery

  2. Stage 2 Completion Rate

    Proportion of participants who successfully complete Stage 2 completion hepatectomy among all participants who undergo Stage 1 surgery. The decision to proceed to Stage 2 is made by the multidisciplinary team based on graft volume growth (target GRWR ≥0.8% or graft volume doubling) and recovery of liver function. Participants who do not proceed to Stage 2 by Day 42 after Stage 1, or who discontinue the surgical pathway due to tumor progression or persistent graft dysfunction, are counted as not completing Stage 2.

    Measured: From Stage 1 surgery until Stage 2 completion or up to Day 42 after Stage 1 surgery
