Prof. Dr. Katja C. Siegmann-Luz, Diagnostic Breast Cancer Centre in Königs Wusterhausen, Germany.
The patient presented with a new, 3-week old palpable finding in the right breast. Normal findings in screening of dense glandular tissue and for macromastia. Sonography shows 24 mm diameter malignoma-typical lesion top right at 12 o’clock, BI-RADS 5. Poorly differentiated triple-negative breast cancer NST G3 confirmed by ultrasound-guided punch biopsy.
Lesion is marked with Tumark Vision (Image 1) with ultrasound guidance prior to neo-adjuvant chemotherapy. A tumor with 26 mm diameter surrounding the clip is differentiated in post-intervention breast tomosynthesis (Image 2).
Course of treatment
Sonographic check-up after 6 months of neo-adjuvant therapy shows partial remission of the tumor and an unchanged position of Tumark Vision (Image 3). Ultrasound-guided, pre-operative wire marking of the clip (Image 4), clearly visible in segment resectate (Image 5). Tissue margins are tumor-free (R0).
Long-term ultrasound visibility of the placed clip is helpful in planned breast-conserving surgery (BET) after neo-adjuvant therapy especially in case of tumor remissions and if tumor delimitation is limited. Thanks to its geometry, Tumark Vision can easily be delimited as hyperechoic ring-shaped structure.
