Breast cancer localization is shifting from wire-guided localization to alternative methods, such as the Pintuition Marker® from Sirius Medical. What are the advantages of this approach?
What is the Pintuition Marker®?
The Pintuition marker® system, including the small but powerful marker, enables accurate localization of the tumor, allowing for its precise removal. The shift from wire-guided localization to Pintuition Surgical Marker® Navigation allows for workflow optimizations between the radiology department and the surgery department.

The Disadvantages of Wire Guided Localization
Wire-guided localization (WGL) has been the standard for surgical localization since its introduction in the 1970’s. It involves the placement of a thin, flexible wire (similar in size to a fuse wire or fishing line) into the breast prior to surgery. This wire serves as a precise guide for the surgeon, ensuring accurate identification of the targeted area during the procedure.
What are the disadvantages of wire guided localization?
- Timing constraints: The procedure must be performed either on the day of surgery or the day prior, which limits scheduling flexibility.
- Risk of wire dislocation: Proper execution requires advanced navigation skills to minimize the risk of displacement.
- Patient discomfort: The procedure may cause discomfort for the patient.
Reasons to Switch to Pintuition®
In recent years, advancements in technology have led to the development of new devices that address many of the limitations associated with wired systems. Among these, radioactive seed localization (RSL) has emerged as a leading innovation. However, the use of small radioactive sources, along with a strict chain of custody regulations, raises radiation safety concerns, which have hindered its widespread global adoption.
Sirius Pintuition® represents the next generation of breast cancer localization technology.
The rice-grain-sized Pintuition Marker® can be implanted into the tumor days or weeks before surgery. During the surgery procedure, the advanced GPSDetect software provides real-time, directional guidance using audio and visual feedback for unmatched precision to locate tumors, enabling surgeons to navigate to the tumor more easily and precisely. Sirius Pintuition® is intended to offer the advantages of radioactive seed localization while eliminating its associated challenges, such including the nuclear medicine department.
How is the Pintuition Marker® Placed?
The Pintuition Marker® is pre-loaded into a sharp 14-gauge needle with an ultrasound-enhanced tip. It is secured by the needle against a locking mechanism, providing tactile resistance upon deployment. To place the marker, first visualize the target tissue using the preferred imaging modality, such as ultrasound. Apply local anesthesia to the area, then remove the protective sheath from the needle immediately before use. Insert the needle and slowly advance it until the tip is clearly visualized within the target tissue. Once the needle tip is confirmed in position, remove the spacer and deploy the marker by gently pushing the green stylet handle until slight resistance is felt. Continue advancing until the marker is fully deployed. Finally, retract the needle using a rotating motion and verify the marker's placement with an ultrasound or mammogram.

The Pintuition Marker's® magnetic technology offers the following advantages:
- Robust marker: Encapsulated in high-grade, nickel-free, biocompatible titanium.
- No signal loss: A permanent magnet generates a constant magnetic field, enabling precise detection from any direction, even in fluids.
- Non-radioactive: No need for a nuclear medicine department or the administrative burden due to radiation safety handling procedures.
- Minimal discomfort: Intuitive and accurate devices that enable surgeons and radiologists to deliver optimal care.
