Introduction :
Breast cancer is one of the leading causes of death in women. In recent times, rapid advances in diagnostic imaging modalities have resulted in early detection of breast cancer. Impalpable breast lesions now constitute a larger proportion of breast lesions which subsequently require pre-operative image-guided hookwire localization (HWL) to facilitate surgical excision. As the use of digital breast tomosynthesis (DBT) increases, mamographically and sonographically occult lesions have also been increasingly detected, leading to an inherent drive towards DBT-guided HWL as the next step in clinical management of these once difficult-to-detect breast lesions.
Objectives :
The authors sought to evaluate the feasibility, accuracy and safety of this relatively new technique in a single tertiary referral centre.
Methodology :
A retrospective review was made for all DBT-guided HWL performed over a 6-month period from April to October 2018. A query of the electronic patient database identified 10 consecutive women (average age = 51 years, age range = 41-64 years) with a total of 10 targeted lesions for DBT-guided HWL with the use of commercially available equipment. Selenia ® Dimensions ® (by Hologic Inc) was the mammography system utilized for the purpose of this examination.
Result & Outcome :
The presence of a microcalcification cluster was the imaging finding identified in 100% of patients. Histological findings were malignant in 1 of the 10 lesions (10%). Technical success of DBT-guided HWL was achieved in all patients (100%). No peri-procedural complications were noted (0%). In conclusion, DBT-guided HWL is a feasible and safe image-guided technique which can be applied in the impalpable, mammographically and sonographically occult breast lesion.
