Brief Summary

the ARMANI trial will test the hypothesis, if an anatomic resection (AR) improves long-term outcome vs. a non-anatomical resection (NAR) in patients undergoing surgery for RAS-mutated colorectal liver metastasis (CRLM).

Detailed Description

Despite increasing application and success of personalized treatment in medical oncology, little progress has been made in personalized surgical cancer therapy. The ARMANI trial presents the first prospective, randomized trial to evaluate effectiveness and safety of molecular-guided resection in patients with colorectal liver metastasis (CRLM). While CRLM might be removed independently of the liver's segmental borders, retrospective data favor anatomic resections in the subgroup of patients with a mutation in the RAS oncogene. Therefore, the ARMANI trial will test the hypothesis, if an anatomic resection (AR) improves long-term outcome vs. a non-anatomical resection (NAR) in patients undergoing surgery for RAS-mutated CRLM. The trial will be carried out among 11 high-volume centers of hepato-biliary surgery in Germany. A total of 220 patients will be enrolled and randomized in a 1:1 ratio to undergo an AR vs. NAR. The primary endpoint is intrahepatic disease-free survival (iDFS). In addition, the study will provide important data on perioperative outcomes and quality of life for both surgical techniques. Given the trend among liver surgeons to aim for parenchymal-sparing operations to preserve liver parenchyma, a positive trial will be practice changing and present the first piece of high-level evidence on benefits of personalized surgical therapy guided by the tumor's mutational profile in patients with CRLM.

Primary Outcome Measures
NameTimeMethod
Intrahepatic disease-free survival (iDFS)24 months

Time from operation date to date of disease recurrence in the liver, followed up at intervals of three months for a maximum duration of 24 months or until death. Any new, solid lesion in the liver after resection of all CRLM that fulfils imaging criteria (CT, MRI) of a metastasis is counted as an iDFS event.

Secondary Outcome Measures
