Just a follow-up to yesterday's post regarding surgical margins in breast cancer. Will this device obviate inking the specimen or the debate about how much margin is "enough"?
Quoted from Medscape article by Zosia Chustecka:
The new device, MarginProbe (Dune Medical Devices Inc), consists of a single-use probe that analyzes breast tissue removed during a lumpectomy. Using radiofrequency spectroscopy, the probe analyzes "electromagnetic signatures" at the margins of the surgically removed breast tissue and compares them to an internal library of signatures taken from both healthy and cancerous tissue. Within the space of 5 minutes, the probe provides an assessment of the excised tissue, indicating whether or not it is cancerous.
