IntraOperative UltraSound Guided vs Wire Guided vs Magnetic Seed Guided Breast-Conserving Surgery for Non-palpable Tumors

Summary

This is a multi-center, randomized, open-label clinical trial that will enroll 1302 adult patients with non-palpable breast lesions. Participant eligible for the study will be randomized in a 1:1:1 ratio to one of the pre-surgery lesion localization: IOUS HydroMark™ (experimental arm A), magnetic Sirius Pintuition Seed® (experimental arm B) and the wire localization technique (control arm). The randomization will be stratified by lesion type (solid non-palpable (type B); non-solid non-palpable (e.g., microcalcification clusters, architectural distortive areas) (type C); post-NACT residual lesions (type D), and clinical center.

• Breast Cancer
• Breast-Conserving Surgery

Interventions

PROCEDURE

IOUS HydroMark™

IOUS HydroMarkTM allows marking the tissue during percutaneous breast biopsy. This is a sterile, single-use marker made of resorbable hydrogel, which expands upon contact with bodily fluids and is then gradually absorbed. The hydrogel is visible on ultrasound. Inside the hydrogel, there is a metallic spiral (titanium/steel) that remains permanently visible in radiographic and MRI examinations even after the hydrogel has been fully absorbed. The HydroMARK Breast Biopsy Site Marker is made of a resorbable hydrogel that expands with fluid and is then resorbed. The hydrogel material is visible under ultrasound. Embedded in the hydrogel is a coiled metallic wire that will be permanently visible under x-ray and MRI when the hydrogel is resorbed. The HydroMARK Biopsy Site Marker is a permanent implant and is not intended to be removed unless the marked tissue is determined to require surgical removal. The marker is supplied pre-loaded in applicator devices designed.

PROCEDURE

Magnetic Sirius Pintuition Seed®

The Pintuition Localization System is intended as a magnetic soft tissue localization system. The magnetic Pintuition Seed is indicated for preoperative percutaneous implantation into soft tissue (glandular, fibrous or fatty tissue of breast; lymph nodes in the axillary and inguinal region; subcutaneous tissue and skeletal muscle tissue) for temporary marking (\<180 days) of a tissue of interest (e.g. tumor or a suspected lesion) indicated for surgical removal. Using the Pintuition Detector as magnetic guidance or, alternatively, image guidance (ultrasound or x-ray), the Pintuition Seed can be intra-operatively localized and removed together with the tissue of interest.

PROCEDURE

Wire localization (WL)

Single-use, repositionable needle for preoperative localization of breast nodules with a single hook, equipped with a depth limiter. Designed for the localization of non-palpable breast lesions in the preoperative phase. It includes a fixation clamp to stabilize the positioning of the wire.
