About this study

Official title: Efficacy of a Novel, High-Sensitivity, Portable, Hand-Held Gamma Camera Used Intraoperatively for Identification of Sentinel Lymph Nodes With Lymphoscintigraphy

This study evaluates the ability of a prototype intraoperative handheld gamma camera (pIHGC) to image (detect) sentinel lymph nodes (SLNs) in melanoma and breast cancer during surgical excision, as compared to standard of care intraoperative gamma probes (GP). The unit of study in this trial was SNLs rather individual participants. Each device was assessed for relative node detection sensitivity (S) of those SLNs.

Read the detailed description

Lymphoscintigraphy is an accepted and commonly-performed procedure used for staging of certain cancers, especially melanoma and breast cancer. It involves injecting a small amount of radioactivity under the skin in order to identify lymph nodes which should be biopsied (ie, the "sentinel lymph node, SLN") to determine if cancer has spread. The study objective was to evaluate the potential benefit of a new, camera-based technology (prototype device) which allows actual images to be obtained intra-operatively in the identification of sentinel nodes.

Each device was assessed for relative node detection sensitivity (S), defined as the proportion of sentinel lymph nodes (SLNs) that were identified with each instrument, with the proportion determined as the number of true positives (TP) divided by the total evaluated (N).

Being tested
Prototype intraoperative handheld gamma camera (pIHGC), Lymphoscintigraphy with intraoperative gamma probes (GP), radioactive Tc99M
Medical subject headings
Multiple Myeloma, Breast Neoplasms

What participants receive

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

  • Prototype intraoperative handheld gamma camera (pIHGC)Device

    The prototype intraoperative handheld gamma camera (pIHGC) consists of a parallel-hole lead collimator coupled to a pixilated sodium iodide-thallium [NaI(Tl)] scintillation crystal array, itself coupled to a flat panel, multi-anode Hamamatsu H8500 position-sensitive photomultiplier tube. The collimator is 5x5 cm2 large in area and 1.5 cm thick, with 1.3 mm hexagonal holes and 0.2 mm septa. The 1.7 mm pitch crystal array is composed of 29x29 individual crystals, each 1.5x1.5x6 mm3 in size.

  • Lymphoscintigraphy with intraoperative gamma probes (GP)Device

    Lymphoscintigraphy with standard of care intraoperative gamma probes (GP)

  • radioactive Tc99MRadiation

    Lymphoscintigraphy involves injection of 0.4 to 1.0 mCi of radioactive Tc99M sulfur colloid around at the tumor site.

What is being measured

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

  1. Relative Node Detection Sensitivity

    Relative node detection sensitivity (S) was defined as the proportion of sentinel lymph nodes (SLNs) that were identified with each instrument, with the proportion determined as the number of true positives (TP) divided by the total evaluated (N). The outcome result is expressed as the percentage for each device with 95% confidence intervals.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Prototype intraoperative handheld gamma camera (pIHGC), Lymphoscintigraphy with intraoperative gamma probes (GP) and radioactive Tc99M in people with Multiple Myeloma and Breast Cancer, run by Stanford University at 1 site in United States.

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 3 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: finished, as of the sponsor's last update on 30 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 30 Apr 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Relative Node Detection Sensitivity (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01314963, which also lists 1 linked publication.

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 30 Apr 2018.
