In Colorectal Cancer, Donating Half a Liver Could Save Lives

That’s not a complete contraindication, but if you look at the most updated inclusion criteria of programs, like the ones that the one that we have here at Beth Israel Deaconess and many others, the inclusion criteria protocols include patients who have only hepatic disease.

So, if there are no extrahepatic mets, the resection of the primary has been done or will be done after a multidisciplinary discussion. We want to make sure they have the absence of BRAF mutation, and that they don’t have disease progression while on chemotherapy. So hopefully we have data from enough months to be able to make sure that there’s no intrahepatic or extrahepatic progression while on chemotherapy.

And that’s including CEA and also looking at the imaging.

Dr. Schlechter: When you’re seeing a patient, how much chemo do you think they should have? What’s a good run chemotherapy-wise for these patients? Let’s say, before I refer a patient to you, how much chemo should they have? And then what should I do? Do I get a PET scan? Do I get MRI? What’s the right scanning I should do to prove there’s no extrahepatic disease before sending a patient in for consideration?

Dr. Dib: First, we need to confirm unresectability. Referring patients early is always a good measure to make sure that we’re all in agreement that it’s an unresectable patient. Having a PET scan from the very beginning is helpful because it shows the disease before doing chemotherapy.

In terms of the lines of chemotherapy, ideally in the TRANSMET trial, for example, the idea was to show tumor control for at least 3 months, with less than three lines of chemotherapy. Some patients will do that with FOLFIRI. It depends on the case.

I think some of those evaluations will need a multidisciplinary discussion. In our case, we are connected to the Norway team. We frequently talk with the Oslo team and an international community of transplant centers to get opinions on particular cases.

But I think referring patients early is a good measure. If we don’t think that they qualify, we will let the team know. We’re strictly looking at patients who have unresectable liver mets that don’t have extrahepatic disease. The idea is to do a primary tumor resection, and then get to transplantation, hopefully after 6 months. In some cases that have some concerns in terms of tumor biology, we may even extend the time from diagnosis to transplant to over 1.5 years.

Dr. Schlechter: Excellent. And what’s the experience like for these patients? In training as a resident many years ago, I saw patients with cirrhosis who went on to have a liver transplant, and that was sort of trading one disease for another. What is the posttransplant, or the remission, experience of a liver transplant for colorectal cancer like for the patient?

Dr. Dib: That’s a very important point. I think that transplantation has gotten better and better, as has chemotherapy systemic therapy. The liver transplantation experience from 20 years ago has improved dramatically. I think the quality of life of liver transplant patients after transplantation has increased quite a bit.
