Trial summary

The results of this study may or may not establish useful baseline data, which will help us understand how bone marrow derived adult liver stem cells behave in normal healthy adults/volunteers (the control group), and in patients undergoing liver surgery. Read more about this study

About this study

The results of this study may or may not establish useful baseline data, which will help us understand how bone marrow derived adult liver stem cells behave in normal healthy adults/volunteers (the control group), and in patients undergoing liver surgery. The bone marrow is located within your bones and is the organ which is responsible to produce blood cells and stem cells. Bone marrow derived adult liver stem cells are normal cells in your bone marrow. These liver stem cells have the capacity to regenerate or in other words to rebuild the liver after liver surgery, a process called liver regeneration. These cells are very important for the liver to regrow its tissue after liver surgery. These cells are thought to be activated in times of need by the liver.

Situations like liver surgery are one of these occasions when the liver will need the "extra help" from these stem cells.

The results of this study will establish the baseline data necessary for the understanding of how to harness the ability of these stem cells in times of liver surgery. Improvements in the ability of the liver to regrow after surgery is thought to decrease complications related to liver surgery. Harnessing this unique ability of stem cells may be utilized in the future to enhance the regrowing process of liver tissue after liver surgery, called liver regeneration.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • blood drawnOther

    Baseline levels of bone marrow derived liver stem cells from normal healthy volunteers, which will be drawn once Two 5ml blue tubes).

  • blood drawnOther

    At the time of preoperative testing, patients will have two extra test tubes (5cc blue top) of blood drawn for determination of pre-operative base line levels of bone marrow derived liver stem cells in peripheral blood. Intraoperatively, blood will be drawn after liver resection (two tubes of 5cc blue top). Two extra tube of blood will be drawn at the same time of routine postoperative blood drawing to determine levels of bone marrow derived liver stem cells in peripheral blood on post-operative days #1, and #3.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine qualitatively and quantitatively whether bone marrow derived liver associated stem cells are mobilized from the bone marrow in patients undergoing major liver resections (3 or more liver segments).

    Measured: conclusion of study

Secondary outcomes (1)
  1. To determine whether a difference exist in the baseline levels of bone marrow derived liver associated stem cells between normal healthy subjects/ volunteers and cancer patients prior to liver surgery.

    Measured: conclusion of study

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Cancer, run by Memorial Sloan Kettering Cancer Center.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 19 Mar 2009. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine qualitatively and quantitatively whether bone marrow derived liver associated stem cells are mobilized from the bone marrow in patients undergoing major liver resections (3 or more liver segments). (time frame: conclusion of study). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2009.
