Levende donor levertransplantation for ikke-operable kolorektal cancer levermetastaser

28. september 2026 opdateret af: University Health Network, Toronto

Vurdering af en protokol ved hjælp af en kombination af neo-adjuverende kemoterapi plus levende donor levertransplantation for ikke-resekterbare levermetastaser fra kolorektal cancer

Patients with unresectable liver metastases (LM) from colorectal cancer (CRC)have a poor prognosis. In patients with resectable disease, surgery offers a distinct survival benefit. This study will offer live donor liver transplantation (LDLT) to select patients with unresectable metastases that are 1) limited to the liver and 2) stable (non-progressing) on standard chemotherapy. Potential participants will be evaluated for liver transplant suitability and must also have a willing, healthy living donor come forward for evaluation. Those participants who undergo LDLT will be followed for survival, disease-free survival and quality of life for 5 years and compared to a "control group" of participants who drop out of study prior to transplantation due to reasons other than cancer progression.

Detaljeret beskrivelse

Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Approximately half of all patients develop metastases, often to the liver or lung. Surgical treatment of liver metastases (LM) is the only curative treatment option; however, it has been estimated that only 20-40% of patients are candidates for liver resection. Surgery offers a distinct survival advantage: the 5-year survival after liver resection for LM is around 40-50% in most studies versus 10-20% 5-year survival for chemotherapy alone.

In cases where the colorectal metastases are isolated to the liver but "unresectable", the total hepatectomy resulting from liver transplantation would remove all evident disease. CRC LM are considered an absolute contraindication for liver transplantation (LT) at most centers but recent reports of LT for colorectal LM from a single center in Oslo, Norway demonstrated a 5-year survival of 56%. The Norway study was not stringent about inclusion criteria or pre-transplant chemotherapy, and transplanted patients whose tumors were actively growing. As a result many participants developed disease recurrence quite rapidly following transplant. The investigators hypothesize that tighter criteria would result in improved outcomes.

Unfortunately, with a lack of deceased donor grafts for the investigators existing transplant patients, the investigators cannot utilize decease donor grafts for this study. Therefore the investigators will explore Living Donor Liver Transplantation (LDLT). Furthermore, LDLT is an elective surgery, allowing for more control over pre-transplant chemotherapy and tumor monitoring. This study will offer live donor liver transplantation (LDLT) to select patients with unresectable metastases that are 1) limited to the liver and 2) stable (non-progressing) on standard chemotherapy. Potential participants will be evaluated for liver transplant suitability and must also have a willing, healthy living donor come forward for evaluation. Those participants who undergo LDLT will be followed for survival, disease-free survival and quality of life for 5 years and compared to a "control group" of participants who drop out of study prior to transplantation due to reasons other than cancer progression.
