Brief Summary
Preoperative image-guided data correlates with the actual intraoperative reality. Computer-assisted preoperative planning combined with intraoperative mapping of even very small lesions allows for improved accuracy during complete oncological resection / ablation. In the short- and long-term this possibly results in better patient outcome.

Outcome Measures
Primary Outcomes (1)
TRE, measuring the error in the prediction of a surgical target location when using the navigation system.
12 months
Secondary Outcomes (1)
1.Identification of suitable landmarks for registration
15 months
Interventions
The patient is placed in a supine position and standard laparotomy (either via subcostal, midline or inverted hockey-stick incision) is performed. After mobilization of the liver, surgical swabs are packed around the organ to prevent unnecessary movement of the liver during the acquisition of the landmarks and the subsequent surgical procedure
Eligibility Criteria
patients that are still considered unresectable at the time point of presentation
You may qualify if:
- Written informed consent
- Male patients and non-pregnant, non-lactating females aged ≥18 years of age (negative serum/urine pregnancy test result at screening)
- Patients must be candidates for surgical liver resection and/or MWA (at least one anatomical segment) of primary or metastatic liver cancer. The liver tumors must be present on preoperative imaging study (CT and/or MRI).
You may not qualify if:
- Any condition which, in the judgment of the clinical investigator or his designee, might increase the risk to the subject or decrease the chance of obtaining satisfactory data to achieve the objectives of the study.
- A mental condition rendering the patient unable to provide informed consent.
- Patients with hereditary hematological / coagulation disorders unrelated to their liver disease or cirrhosis of the liver classified as Child's B or C.
