Summary
The ABBI-system enables digital intraoperative mammography for precise breast cancer excision. This new method offers reliable localization and fast imaging, improving breast-conserving therapy outcomes.
Area of Science:
- Radiology
- Oncology
- Surgical Oncology
Background:
- Needle-localized lumpectomy is standard for non-palpable lesions, with specimen radiography confirming excision.
- Intraoperative mammography of the breast has been technically challenging until now.
Purpose of the Study:
- To evaluate the efficacy of the ABBI-system for excising small breast carcinomas.
- To assess if the ABBI stereotactic biopsy device can be used for breast-conserving therapy without compromise.
Main Methods:
- A pilot study investigated excising small carcinomas using the ABBI stereotactic biopsy device (max. 20 mm diameter).
- A prospective study involved 69 patients diagnosed or treated with the ABBI-system, including cylindrical excisions for primary lesions and suspected recurrences.
Main Results:
- Cylindrical excisions were performed in 60 patients with primary lesions; 11 invasive and 5 intraductal carcinomas were diagnosed.
- Breast-conserving surgery was performed for 7 invasive and 2 intraductal cancers.
- In 9 cases of suspected recurrence, 7 excisions revealed 1 invasive and 3 intraductal carcinomas, leading to mastectomy in 4 patients.
Conclusions:
- The ABBI-system facilitates reliable stereotactic localization and rapid intraoperative imaging for breast lesions.
- It supports breast-conserving therapy for small carcinomas and suspected recurrences, with good cosmetic results and uneventful postoperative courses.
- The system is not suitable for lesions close to the chest wall.
