Follow-up Yttrium-90 Internal Pair Production PET/CT vs Brehmsstrahlung Imaging in Patients With Primary/Metastatic Liver Tumors

December 27, 2017 updated by: Jason Salsamendi, University of Miami

Follow-up Yttrium-90 Internal Pair Production PET/CT Imaging in Patients With Primary or Metastatic Liver Tumors as Compared With Brehmsstrahlung Imaging: A Prospective Case Series

This is a prospective non-blinded case series involving the acquisition of a pair production PET/CT as soon as possible after an already performed Y-90 Sirspheres treatment of hepatic malignancy. It will be performed in addition to the standard Brehmsstrahlung SPECT scan. The sequence of the two scans in each case (PET/CT vs SPECT) will be determined by availability of the scanners at the time. However, it is intended that both be acquired on the day of the Y-90 treatment.

The length of subject participation will be one year.

The measures used will be mostly qualitative in nature, and will include:

  • Correlation with expected vs. achieved tumor coverage by the treatment
  • Correlation between treatment distribution depicted by Brehmsstrahlung scans vs. the Internal Pair Production PET/CT scans, to.
  • Detection of non-target embolization, where applicable, and qualitative comparison between the two modalities as to the conspicuity of the abnormality

Qualitative methods will be used by the analysis of the obtained PET/CT images and comparing them to the Brehmsstrahlung SPECT images as previously described.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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:

  • Recipient of Selective Internal Radiation Treatment within 5 days.
  • Anticipated ability to remain still for up to 40 minutes

Exclusion Criteria:

  • Anticipated Inability to lie still for up to 40 minutes
  • Severe claustrophobia
  • Significant cardiovascular instability, or instability of other medical/surgical conditions, such that it would be deemed unsafe or technically not feasible to obtain a PET/CT, as determined by the any member of the investigative team
  • Failed deployment of the planned Y-90 treatment for any reason

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Y90 Based PET/CT Scan
Device: PET/CT Scan
Subjects will receive a PET/CT Scan in addition to SPECT imaging, from the level of the lower chest to the lower pelvis, typical of an abdominal CT, usually within 1-3 hours after Yttrium-90 treatment.

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
Number of Subjects Whose Y-90 Based PET/CT (Positron Emission Tomography/Computed Tomography)Scans Detected Extrahepatic Non-target Embolization.
Time Frame: 12 months
Number of participants with detected extrahepatic non-target embolization. A qualitative comparison between the two modalities (Y-90 PET/CT and Brehmsstrahlung SPECT) as to the conspicuity of the abnormality would have been conducted had any participant had that result.
12 months

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
Comparison Between Treatment Distribution Depicted by Tc99mMAA (Technetium-99m Macroaggregated Albumin) Brehmsstrahlung Scans vs. the Internal Pair Production PET/CT Scans.
Time Frame: 12 months
Number of participants demonstrating a similar treatment distribution depicted by Tc99mMAA(Technetium-99m macroaggregated albumin) Brehmsstrahlung scans vs. achieved Y-90 distribution on the Internal Pair Production PET/CT scans.
12 months
Comparison of Y-90 PET/CT to Y90 SPECT
Time Frame: 12 Months
Number of participants with a similar Y90 distribution depicted on Post Y90 delivery PET/CT and SPECT modalities, specifically comparing Y90 distribution within the treated tumors.
