About this study

This clinical trial will enroll up to 130 adult women with a confirmed diagnosis of clinical stage 1 or 2 breast cancer who are undergoing breast cancer surgery with lumpectomy or mastectomy and planned axillary sentinel node biopsy procedure. Participants will undergo lymphatic mapping with technetium Tc-99m (99mTc) sulfur colloid in accordance with routine clinical practice. Injections of 99mTc sulfur colloid will take place the afternoon prior to planned next morning surgery or on the morning of surgery. Participants will undergo lymphoscintigraphy in accordance with standard clinical practice.

Immediately prior to operation, after the induction of anesthesia in the operating room, up to 1cc of 0.5% indocyanine green (ICG) solution will be injected subdermally close to the tumor or into the subareolar region after disinfection of the breast skin. ICG movement will be facilitated by manual massage and monitored with fluorescence imaging. ICG fluorescence will be elicited and detected by Photodynamic Eye (PDE) camera. The lymphatic drainage, made evident by the fluorescent dye, will be monitored in real time on a monitor. The fluorescence will be followed towards the armpit region (axilla) and time for the fluorescence to reach the axilla will be recorded. Following standard practice, an incision will be made in the armpit region. Fluorescent lymph nodes (ICG positive) will be localized and removed and analyzed by a pathologist. Node removal will continue until no residual fluorescence is visible in the axilla. Removed nodes will be tested for radioactivity using a standard gamma-detecting probe and the counts per minute will be recorded. Finally, the armpit region will be inspected with the gamma probe to determine if there are any residual radioactive nodes. Residual sentinel nodes (the first node to receive lymph from a tumor) will be removed. For the purposes of this study, the sentinel status of a node will be defined as being flagged as sentinel by either one or both of the ICG or 99mTc methods. The goal of the project is to confirm that axillary lymphatic mapping with ICG leads to similar nodes being labeled as sentinel as lymphatic mapping with 99mTc-labeled radiotracer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To confirm that axillary lymphatic mapping with indocyanine green solution (ICG) solution leads to a similar number of nodes being labeled as sentinel as lymphatic mapping with 99mTc-labeled (technetium Tc-99m sulfur colloid) radiotracer.

OUTLINE:

Participants receive technetium Tc-99m sulfur colloid injection and undergo lymphoscintigraphy according to clinical practice. Prior to surgery, participants also receive indocyanine green solution subdermally close to the tumor or into subareolar region of the breast skin. Participants then undergo axillary sentinel node biopsy and surgery.

What participants receive

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

  • Indocyanine Green SolutionDrug

    Also called IC-GREEN, ICG solution

    Given subdermally

  • Technetium Tc-99m Sulfur ColloidRadiation

    Also called Tc 99m Sulfur Colloid, Tc-99m SC, Technetium Tc 99m Sulfur Colloid

    Given via injection

  • LymphoscintigraphyProcedure or surgery

    Also called Undergo lymphoscintigraphy

    This is a method used to check the lymph system for disease. A radioactive substance that flows through the lymph ducts and can be taken up by lymph nodes is injected into the body. A scanner or probe is used to follow the movement of this substance on a computer screen. Lymphoscintigraphy is used to find the sentinel lymph node (the first node to receive lymph from a tumor), which may be removed and checked for tumor cells. Lymphoscintigraphy is also used to diagnose certain diseases or conditions, such as lymphoma or lymphedema.

  • Axillary Lymph Node BiopsyProcedure or surgery

    Also called Axillary Node Biopsy, axillary sentinel lymph node biopsy

What is being measured

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

  1. Proportion of Sentinel Lymph Nodes (SLNs) Flagged by the Two Methods

    Let A be the number of Tc-positive and ICG-positive sentinel nodes (SNs) detected, B be the number of Tc-positive and ICG-negative SNs detected, and C be the number of Tc-negative and ICG-positive SNs detected. The total number (N) of SNs detected is therefore N = (A + B + C); the proportion of SNs detected by the Tc method (PTc) is (A + B)/N; and the proportion of SNs detected by the ICG method (PICG) is (A + C)/N. Differences in the proportions of SLNs flagged will be compared using a two-sided 95% confidence interval.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A study testing Indocyanine Green Solution, Technetium Tc-99m Sulfur Colloid and Lymphoscintigraphy in people with Stage I Breast Cancer and Stage II Breast Cancer, run by Case Comprehensive Cancer Center 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 3 inclusion and 8 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 Jun 2022. 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 22 Oct 2020). 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?

Proportion of Sentinel Lymph Nodes (SLNs) Flagged by the Two Methods (time frame: Baseline). 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 30 Jun 2022.
