SPCTR

Using light and AI to tell surgeons during an operation if a tumor was fully removed.

removes a tumor while preserving the breast. Whether cancer remains at the cut edge is usually known only after a pathologist examines the tissue several days later. A positive margin can mean another operation or additional radiotherapy.

SPCTR is developing a device that analyzes light reflected from removed tissue and classifies it using AI trained against . It is designed to give the surgical team an answer during the operation, without injecting anything into the patient or bringing another specialist into the room.

Product

SPCTR is developing SPCTRone, a device used during breast-conserving surgery to assess whether cancer remains at the edge of removed tissue. It analyzes reflected light and uses AI trained against pathology to provide a result while the patient is still in the operating room.

Breast surgery as the first clinical use

SPCTR is starting with breast-conserving surgery, where is a frequent and standardized part of the procedure. The company plans to expand the same tissue-analysis approach to other solid tumors.

Dye-free analysis of removed tissue

The device shines light onto the cut surface and analyzes the spectrum reflected by the tissue. Nothing is injected into the patient or added to the specimen.

Designed for the existing surgical team

The AI model is trained against pathologists' assessments of the same tissue. SPCTR aims to provide a result the surgical team can use without an additional specialist in the room.

Market Overview

Breast-conserving surgery is the preferred operation for many patients with early breast cancer, but surgeons usually receive the final margin assessment only after pathology. In a study covering 109,475 Dutch procedures, 10.8% had tumor-positive margins and 40.9% of patients had at least one known risk factor before surgery.

Hospitals already use , , and probe-based devices to assess margins during surgery. These existing workflows show that hospitals will pay for an intraoperative answer, although many require extra operating-room time or specialist interpretation.
