About this study

Official title: Feasibility Study of Targeted Biopsy of Carbon Nanoparticles Labelled Axillary Node After Neoadjuvant Systemic Therapy for Clinically Assessed Positive Axillary Lymph Node (cN+) Breast Cancer

To explore the feasibility of target biopsy of carbon nanoparticles labelled lymph node after neoadjuvant systemic therapy for cN+ breast cancer, and evaluate whether it can accurately predict axillary lymph node status after neoadjuvant systemic therapy.

Read the detailed description

Locally advanced breast cancer patients with clinical assessed positive axillary lymph node (cN+) who receive neoadjuvant systemic therapy (NST) will be enrolled in this study. Before NST, one of the suspected lymph nodes will be subjected to ultrasound-guided core needle biopsy (CNB) or fine needle aspiration (FNA), and a locating clip will be placed. Meanwhile, a small amount of Kanarine (Carbon Nanoparticles Suspension Injection) will be injected into or around the cortex of the locating lymph node as well as other positive lymph nodes. All patients will be confirmed to have axillary lymph node metastasis by pathologic or cytologic examination. After NST, FNA will be performed again for the lymph nodes labelled with previous locating clip. During the operation, the clip labelled lymph nodes were identified with carbon and sent to pathology separately. Meanwhile, the remaining carbon labelled lymph nodes were also separately examined. Axillary lymph node dissection will be performed in all patients. The detection rate of labelled lymph node will be record, and the pathological results of re-FNA of labelled lymph nodes will be compared with postoperative pathological results. Meanwhile, we will also analysis whether carbon labelled lymph node biopsy could predict the overall status of axillary lymph nodes after NST.

    Before NST, one of the clinically assesed positive lymph nodes will be subjected to ultrasound-guided CNB or FNA, and a locating clip (Ultraclip, BARD) will be placed. Meanwhile, a small amount of Kanarine (carbon nanoparticles suspension injection, 0.5ml:25mg, H20073246) will be injected into or around the cortex of the locating lymph node and other clinically assessed positive lymph nodes. Preoperative FNA will be performed again for locating clip labelled node.

What is being measured

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

  1. The accuracy of carbon nanoparticle labelled lymph nodes in predicting axillary lymph nodes

    Before NST, one of the clinically assesed positive lymph nodes will be subjected to ultrasound-guided CNB or FNA, and a locating clip will be placed, meanwhile, a small amount of carbon nanoparticles suspension injection will be injected into or around the cortex of the locating lymph node and other clinically assessed positive lymph nodes. During operation, carbon nanoparticle labelled lymph nodes will be identified and sent for examination. Then calculate the accuracy of carbon nanoparticle labelled lymph nodes in predicting axillary lymph nodes for postoperative pathology.

    Measured: 1-3 day before NST, the suspected lymph nodes will be injected carbon nanoparticle. During operation, carbon nanoparticle labelled lymph nodes will be identified and sent for examination.

Secondary outcomes (1)
  1. The consistency between the pre-operative FNA of clip labeled lymph nodes and post-operative pathology.

    Before NST, one of the clinically assesed positive lymph nodes will be subjected to ultrasound-guided CNB or FNA, and a locating clip will be placed. Before surgery, the clip labeled node will be punctured (FNA) again. During operation, the clip labeled node will be identified and sent for pathological examination. And then calculate the identification rate of labeled lymph nodes and the consistency between the pre-operative FNA of clip labeled lymph nodes and post-operative pathology.

    Measured: 1-3 day before NST, one of the cN+ nodes will be placed a locating clip. 1-3 days before surgery, the clip labeled node will be punctured again. During operation, the clip labeled node will be identified and sent for examination.

Questions about this trial

What is this clinical trial studying?

A study testing Carbon nanoparticles suspension injection will be injected into or around the cortex of the clinically assessed positive lymph nodes in people with Location and Biopsy of Axillary Lymph Nodes, run by The First Affiliated Hospital with Nanjing Medical University 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 11 inclusion and 15 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 15 Oct 2024. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The accuracy of carbon nanoparticle labelled lymph nodes in predicting axillary lymph nodes (time frame: 1-3 day before NST, the suspected lymph nodes will be injected carbon nanoparticle. During operation, carbon nanoparticle labelled lymph nodes will be identified and sent for examination.). 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 15 Oct 2024.
