NCT05512468

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • Identification rate of tattooed node

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

    12 months

Secondary Outcomes (2)

  • Concordance of tattooed node and sentinel node

    12 months

  • Migration of black dye into other nodes

    12 months

Study Arms (1)

Experimental: Tattooing of biopsied node

OTHER

Prior 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.

Drug: carbon dye

Interventions

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.

Experimental: Tattooing of biopsied node

Eligibility Criteria

Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Female; 2. Aged \>=18 years; 3. With invasive breast cancer; 4. Patients to be treated with neoadjuvant chemotherapy; 5. Patients scheduled to undergo routine fine needle aspiration (FNA) or core biopsy of abnormal axillary lymph node; 6. Patients with operable breast cancer; 7.

Patients who are unable to cooperate with the doctor's recommended surgical treatment (breast conserving surgery or radical surgery) due to personal or family factors; 5. Patients with serious cardiopulmonary diseases, uncontrolled infectious diseases and other non tumor related diseases who can not tolerate comprehensive treatment such as surgery and chemotherapy; 6. Patients with mental illness or other reasons unable to sign informed consent; 7. Patients with poor medical compliance who cannot complete the trial treatment process and follow-up according to the standard according to the researcher's opinion.
