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 group | Role | What they receive |
|---|---|---|
| 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. Receives: Drug: carbon dye |
What is being measured
The primary outcome is the main question the study is designed to answer.
Identification rate of tattooed node
