CT Perfusion Scans in Detecting Changes in Blood Flow to the Liver After Portal Vein Embolization

April 5, 2023 updated by: M.D. Anderson Cancer Center

To Evaluate Perfusion Changes to the Liver Following Pre-Operative Portal Vein Embolization for Patients With Liver Cancer

This trial studies the use of computed tomography (CT) perfusion scans in detecting changes in blood flow to the liver after portal vein embolization in patients with liver cancer. CT perfusion scans use a standard contrast drug given by vein to measure blood flow to the liver. CT perfusion scans may predict the rate and amount of growth of new, healthy tissue on one side of the liver after a portal vein embolization and detect change to the size of the liver tumor as result of the procedure.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess whether perfusion changes to the liver following portal vein embolization (PVE) correlate with hypertrophy of the future liver remnant (FLR).

SECONDARY OBJECTIVES:

I. To assess perfusion changes to liver tumors following PVE. II. To assess whether PVE may affect tumor growth.

OUTLINE:

Prior to PVE, patients undergo CT perfusion scan of the liver and liver biopsy over 15 minutes. Patients undergo a second CT perfusion scan immediately after PVE and a third CT perfusion scan 3-6 weeks post PVE.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients planned to undergo major liver resection for cancer who need PVE to increase the size of the FLR prior to surgery.
  • Patients who are able to understand and give consent to participate in the study.

Exclusion Criteria:

  • Pregnant or nursing.
  • Allergy to iodinated contrast which cannot be safely pre-medicated.
  • History of severe renal dysfunction (glomerular filtration rate [GFR] < 30 mL/min/1.73 square meters). Patients with a GFR between 30-50 mL/min/1.73 square meters will receive the standard contrast-induced nephropathy prophylaxis at our institution (i.e. N-acetylcysteine and sodium bicarbonate [150 mEq/L] in D5W intravenous).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Perfusion changes to the liver following portal vein embolization (PVE)
Time Frame: Baseline up to 6 weeks post PVE
Will assess whether perfusion changes to the liver following PVE correlate with hypertrophy of the future liver remnant (FLR). Perfusion and FLR hypertrophy are two continuous variables. Each patient will serve as his/her own control. Perfusion to the liver (1) before PVE, (2) immediately after PVE, and (3) 3-6 weeks following PVE will be measured and compared. The changes in perfusion will be compared with FLR hypertrophy at the 3-6 week time point to assess correlation.
Baseline up to 6 weeks post PVE

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes to tumor cellular proliferation following PVE
Time Frame: Baseline up to 6 weeks post PVE
Will assess perfusion changes to liver tumors following PVE and whether this may affect tumor growth kinetics. Each patient will serve as his/her own control. Perfusion to the liver tumor(s) (1) before PVE, (2) immediately after PVE, and (3) 3-6 weeks following PVE will be measured and compared. Since a percutaneous biopsy will be performed of a single liver tumor before PVE and the tumor explant will be available following surgical resection, changes to tumor cellular proliferation following PVE can be assessed.
Baseline up to 6 weeks post PVE
