Perimeter Medical Imaging AI (TSX-V: PINK; OTC: PYNKF) highlighted the November 26, 2024 webinar entitled, “Clearer Margins. Greater Confidence. Exploring the Benefits of OTC”, sponsored by the American Society of Breast Surgeons (ASBrS), featuring its first-generation FDA 510(k)-cleared S-Series OCT system.
The webinar included three presenters followed by a Q&A session. Presenters included: Amani Jambhekar, MD, MBA, FACS, Jennifer Tittensor, MD, FACS, and Catherine A. Ronaghan, MD, FACS.
- Highlights of Dr. Jambhekar’s presentation included:
- 10% to 50% of patients require re-excision to achieve clean margins.
- Patients suffer emotional trauma and 66% risk of post-op complications.
- Re-incisions result in 24% increase in healthcare costs.
- Surgeons lack accurate imaging tools.
- Specimens can take up to 2 weeks to confirm margin status.
- OTC bridges technology gap with margin visualization in the OR.
- OTC provides real-time clarity on margins.
- OTC enables surgeons to see 10x the resolution of X-ray and ultrasound for cellular-level visualization; imaging power at 2mm depth.
- OTC provides insight to make more informed decisions.
- Advantages of adopting OCT: patient satisfaction; clinical impact; quality and performance impact.
Dr. Tittensor relayed three case histories of breast cancer surgery using OCT for margin evaluation, within the past year. “A margin that I excised was concerning to the pathologist and OCT, which ultimately did not need to be re-excised,” Dr. Tittensor said. “Over the year, I’ve certainly learned a lot and I think we are getting better at figuring out what to do in the moment. I’m confident over time that this will continue to improve and we will continue to do things to benefit our patients and help them avoid additional surgery.”
Dr. Ronaghan also presented three breast surgery case histories and commented, “You can see where this technology has so many applications. What is interesting to me is that it is kind of a dream come true. So many surgeons have wanted something that would look at every millimeter surface at whatever we remove and it’s looking at it immediately after its removed when it’s fresh. I’m amazed at how quickly it’s scanning and we are able to review those scans. I do not feel at all that it slows me down in the OR,” Dr. Ronaghan said. “I think it’s a beautiful adjunct to pathology.”
Commenting on Perimeter’s slogan, ‘With OCT, surgeons can act in the moment and close with confidence’, she added, “It is really true. It has changed my practice flow. I feel like I’m taking less tissue and my re-excisions are really precisely directed with this technology.”
Perimeter’s commercial-stage S-Series OCT device has received FDA 510(k) clearance under a general tissue indication, which means it has not been evaluated by FDA for use specifically with cancer.
Perimeter recently announced positive topline results from a pivotal clinical trial designed to support its planned FDA PMA submission for approval to market its next-generation B-Series OCT system, which combines proprietary AI technology with OCT, for use during breast-conserving cancer surgeries in the United States.
