Magtrace and Sentimag Magnetic Localization System
Endomagnetics Inc.
INDICATION FOR USE: To assist in localizing lymph nodes draining a tumor
site, as part of a sentinel lymph node biopsy procedure, in patients with breast cancer undergoing a mastectomy. Magtrace™ is intended and calibrated for use ONLY with the Sentimag® system.
ADDRESSING UNMET NEED:
- Sentinel lymph node biopsies are crucial for determining whether a patient’s breast cancer has spread and helping the provider determine the most appropriate course of treatment
- System offers patients undergoing mastectomy an option for their sentinel lymph biopsy procedure that does not require the injection of radioactive materials
SYSTEM DESCRIPTION:
- Sensitive magnetic sensing probe and base unit designed to detect small amounts of Magtrace, the magnetic tracer drug that is injected into breast tissue
- Magtrace particles travel to lymph nodes, become physically trapped in them, facilitating magnetic detection of the lymph nodes
- Following injection of Magtrace, the Sentimag probe is applied to the patients’ skin in areas closest to the tumor site containing the lymph nodes
- Sensing of the magnetic particles is indicated by changes in audio and visual alerts from the base unit, enabling the surgeon to move the hand-held probe around the area of the lymph nodes, and locate the sentinel lymph node or nodes (if there are more than one)
- Surgeon makes a small incision and removes the node, which is checked by a pathologist for the presence of cancer cell
- Negative result: Suggests cancer has not spread to nearby lymph nodes
- Positive result: May indicate cancer present in sentinel lymph node, nearby lymph nodes and, possibly, other organs
- Help determine stage of cancer and develop appropriate treatment plan
EFFECTIVENESS AND SAFETY:
- Trial of 147 patients with breast cancer, n=147, Sentimag System vs. control methodin sentinel lymph node detection ratw
- 94.3% for Sentimag System vs. 93.5% for control
- Overall, 98.0% same detection rate with both Sentimag System and control
- Most common adverse event: Breast discoloration, cardiac disorder (bradycardia) and potential allergic reaction to the magnetic materials
- Contraindication: Hypersensitivity to iron oxide or dextran compounds
