About this study

The primary aim of this prospective, multicentre study is to determine whether the involved node can be marked using black carbon dye and successfully identified at the time of surgery. The secondary aims are to determine the concordance between the tattooed node and sentinel node, migration of black dye into other nodes, and false-negative rate of tattooed node (in patients undergoing ALND after NACT).

Read the detailed description

Pretreatment evaluation of axillary lymph nodes and marking of biopsied nodes in patients with newly diagnosed breast cancer is becoming routine practice. Tagging of biopsied axillary lymph nodes with metal markers, similar to what is done for suspicious breast lesions, is being adopted in clinical practice. The need to mark a positive axillary lymph node becomes especially relevant in cases where neoadjuvant chemotherapy (NACT) is anticipated so that these nodes may be identified at the time of surgery. Measures that improve both the accuracy of nodal evaluation after NACT and the ability to assess treatment response are desirable in order to tailor therapies for breast cancer treatment. The investigators sought to test tattooing of biopsied axillary lymph nodes with a sterile black carbon suspension.

What participants receive

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

  • carbon dyeDrug

    Tattooing (marking) of biopsied node with carbon dye at the time or at a separate session of fine needle aspiration or core biopsy or separate visit under ultrasound guidance. The dye will be injected in the cortex of the node and the perinodal tissue under ultrasound guidance. Patients will undergo standard (routine) armpit surgery and may receive neoadjuvant chemotherapy as planned by the clinical team. This could be removal of a few lymph glands (sentinel node biopsy) or removal of all the lymph glands (axillary lymph node dissection) in the armpit. The surgeon will try to identify and remove the tattooed lymph gland at the time of planned armpit surgery.

Study groupRoleWhat they receive
Experimental: Tattooing of biopsied nodeOtherPrior to NST, suspicious axillary lymph nodes were biopsied by core needle or fne needle aspiration. The largest and/or biopsy-confrmed metastastic node was then injected with highly purifed carbon suspension either at the time of biopsy or at a separate session.
Receives: Drug: carbon dye

What is being measured

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

  1. Identification rate of tattooed node

    Proportion of patients in whom tattooed node/s were identified.

    Measured: 12 months

Secondary outcomes (2)
  1. Concordance of tattooed node and sentinel node

    Concordance rate: defined as the percent of patients in whomthe tattooed nodeis the sentinel node.

    Measured: 12 months

  2. Migration of black dye into other nodes

    The number of black nodes at the time of sentinel node biopsy or axillary lymph node dissection.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing carbon dye in people with Breast Cancer and Neoadjuvant Therapy, run by Fujian Medical University Union Hospital at 1 site in China.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 23 Aug 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 China. 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?

Results are not available in the source record.

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

Contact Chuan Wang (13365910252, chuanwang1968@outlook.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification rate of tattooed node (time frame: 12 months). 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 23 Aug 2022.
