The Research Group conducts clinical studies and collaborate on translational studies for the treatment of hepatobiliary malignancies.
About the group
We have recently completed two major clinical trials address key issues in liver surgery (ALPPS and laparoscopic liver resection). We are currently putting all our effort in the ASAC trial but continuously work on hypotheses for new RCTs.
Our clinical department is a major provider of surgical specimens necessary for translational research. We therefore focus on close partnership with several key research groups within the field of molecular medicine and tumor Genetics.
The Groups goal is to ensure adequate research infrastructure and financing to make sure that clinical and translational hepatobiliary research activity becomes an integrated part of all aspects of the day to day practice in our Department.
The main aim of the research group is to conduct clinical and translational studies for the treatment of hepatobiliary malignancies. The group has also register-based studies to evaluate and improve patient treatment.
- The ASAC study, Scandinavian multicentre, placebo-controlled, randomized trial, initiated by our group, investigating the role of aspirin as adjuvant after surgery for colorectal liver metastases, is still recruiting patients and has now 300 of 800 patients included (www.asac.no). The trial is funded by Research Council of Norway, Norwegian Cancer Society, and KLINBEFORSK.
- The LIGRO study, Scandinavian multicentre, randomized study investigating portal vein embolization vs ALPPS as a method for promoting growth of liver remnant prior to large liver resections. Primary results are published and sub-analyses are still going on to find the best treatment method.
- The Oslo COMET trial, single centre, un-blinded, randomized trial comparing laparoscopic and open surgery for colorectal liver metastases. The primary end-point is published and sub-analyses and sub-studies are still going on.
- The SMART study, is a translational study on colorectal cancer and liver metastases led by Profs Ragnhild Lothe and Arild Nesbakken.
