Scientific titleInfluence of two different resection techniques of liver metastases from colorectal cancer on haematogenous tumour cell dissemination: a prospective randomised multicentre trial
Study acronymAnterior Approach Study
Study hypothesisWe hypothesise that intraoperative haematogenous tumour cell dissemination could be reduced or prevented by using the anterior approach technique in resection of colorectal liver metastases.

Please note that as of 11/02/2009 this record was updated to include an amended end date. The initial end date at the time of registration was:
Initial anticipated end date: 28/02/2009
Ethics approval(s)Added 11/02/2009: Ethics Committee of University of Heidelberg Medical School gave approval in October 2002.
ConditionLiver cancer
InterventionPatients with liver metastases from colorectal cancer scheduled for a potentially curative normal or extended right hemihepactomy.

The study will be performed as a prospective randomised multicentre trial. Patients will be randomised intraoperatively in each institution: one group will undergo conventional liver resection and the other group will be operated with the anterior approach technique.
On day 0 the patient will undergo exploration. In case of suspected extrahepatic spread (including grossly involved lymph nodes) frozen sections of the suspicious areas will be performed. All these procedures are considered routine and are carried out for any patient undergoing resection of liver tumours. Patients with positive extrahepatic spread (including positive lymph nodes) routinely do not undergo liver resection, these patients will therefore be excluded from the study. After extrahepatic tumour spread is excluded, the surgeon will again evaluate whether resection of the tumour can be performed by either technique. Once this criteria is met, the patient will be randomised to one of the two groups: one group will undergo conventional liver resection and the other group will undergo resection using the anterior approach technique.
Intervention typeOther
Primary outcome measureTo compare the anterior approach to the conventional technique of hepatic resection for colorectal metastases with respect to the incidence of intraoperative haematogenous tumour cell dissemination. We hypothesise that intraoperative haematogenous tumour cell dissemination could be reduced or prevented by using the anterior approach technique in resection of colorectal liver metastases.
Secondary outcome measures1. Survival of the patients (overall and disease-free survival)
2. Blood loss
3. Duration time of resection
4. Transfusion requirements
5. Complication rates

Assessed between the two different liver resection techniques. Furthermore the prognostic relevance of tumor cell detection in blood and bone marrow and the comparison of tumor cell detection by different detection methods will be analysed.

Target number of participants150

Participant inclusion criteria1. Hospitalised patients of the Department of Surgery, University of Heidelberg or of the Hepatobiliary Division, Department of Surgery, Memorial Sloan-Kettering Cancer Center, New York, aged greater than 18 years (no upper age limit)
2. Are considered for a potentially curative (R0) right hepatectomy (removal of segments 5,6,7,8), extended right hepatectomy (removal of segments 5,6,7,8, part of segment 4) or right trisegmentectomy (removal of segments 4,5,6,7,8) for colorectal liver metastases

There will be 150 patients (75 each group) accrued in this study (excluding patients who underwent R1 resection and/or with an intraoperative blood loss of greater than or equal to 2000 cc).
Participant exclusion criteriaPatients with positive extrahepatic spread (including positive lymph nodes) routinely do not undergo liver resection, these patients will therefore be excluded from the study.
