Plain English summary of protocol

Background and study aims
Liver resection is surgical removal of a portion of the liver. It is the treatment for multiple cancerous and non-cancerous masses in the liver. After removing a part of the liver it has the ability to regenerate. In some laboratory and animal studies N-acetylcysteine, a medication commonly used in treatment of acetaminophen (a pain medicine) overdose, has shown the ability to improve liver regeneration after resection. This study will test this theory in humans.

Who can participate?
All adult patients who are undergoing a major resection of the liver.

What does the study involve?
Patients are randomly allocated to either receiving N-acetylcysteine after the liver resection or not receiving it. There are no other differences in the treatment.

What are the possible benefits and risks of participating?
The potential benefit is improved liver regeneration. Potential risks are side effects from receiving the medication.

Where is the study run from?
The Foothills Medical Center, Calgary, AB, Canada.

When is study starting and how long is it expected to run for?
The study ran from February 2007 until June 2012.

Who is funding the study?
Alberta Health Services (Canada).

Scientific titleEffect of N-acetylcysteine on liver recovery after resection: a randomized clinical trial
Study objectivesThe objective of this study is to determine whether N-acetylcysteine can reduce the incidence of postoperative liver dysfunction and the overall complication rate when administered following major hepatic resection (two or more Coinaud segments).
Ethics approval(s)Conjoint Health Research Ethics Board, University of Calgary, 18/05/2010, ref. E18866
Health condition(s) or problem(s) studiedDecrease in liver failure after liver resection for any diagnosis
InterventionBoth randomized groups will undergo the same preoperative and intraoperative management.
The only difference in postoperative management will be use of N-acetylcysteine infusion - 150 mg/kg of NAC in 200 ml of 5% glucose over 45 minutes upon arrival in the post-anaesthesia recovery room. Then 50 mg/kg of NAC in 500 ml of 5% glucose over 4 hours, followed by 100 mg/kg in 1000 ml of 5% glucose over the next 16 hours, followed by 100 mg/kg in 1000 ml of 5% glucose per day over the next 3 days, which will be administered in six infusions of 50 mg/kg in 500 ml of 5% glucose, given over 12 hours each (intervention group only)
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)N-acetylcysteine
Primary outcome measureOverall complication rate. These will be recorded in a prospective fashion throughout the trial. Coding will then be done according to the Clavien-Dindo classification, which is the most common description of types of complications (grade I, II, IIIa, IIIb, IVa, IVb and V).
Secondary outcome measuresPostoperative liver failure as defined by:
1. The 50-50 criterion (PT>50% (INR>1.7), bilirubin > 50 umol/l (3 mg/dL) on postoperative day 5)
2. Length of stay
3. Postoperative mortality
