Application of Preoperative Axillary Lymph Node Marking With Nano-Carbon in Breast Cancer Patients Before Neoadjuvant Chemotherapy

NCT05512468 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 200

No results posted yet for this study

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).

Conditions

Interventions

DRUG

carbon dye

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.
