Introduction
In Australia, the usual approach to breast lesions where core biopsy returns an uncertain result (“B3” breast lesion) is to perform surgical diagnostic open biopsy (DOB). This is associated with patient time off work, costs of hospital admission, risks of general anaesthesia and surgical complications. The majority of B3 lesions return benign results following surgery. Vacuum assisted excision biopsy (VAEB) is a less invasive, lower cost alternative, and is standard of care for selected B3 lesions in the United Kingdom. Similar use of VAEB in Australia, could save many women unnecessary surgery. The aim of this study was to document our experience during the introduction of VAEB as an alternative to DOB for diagnosis of selected B3 lesions.
Methods
The multidisciplinary team developed an agreed VAEB pathway for selected B3 lesions. Technically accessible papillary lesions, mucocele‐like lesions and radial scars without atypia measuring ≤ 15mm were selected.
Results
Over a 7 month period, 18 women with 20 B3 lesions were offered VAEB. 16 women (18 lesions) chose VAEB over DOB. Papillomas were the commonest lesion type. All lesions were successfully sampled: 17/18 were benign. One lesion (6%) was upgraded to malignancy (ductal carcinoma in situ on VAEB, invasive ductal carcinoma at surgery). No major complications occurred. Patient satisfaction was high: 15/16 respondents would again choose VAEB over surgery.
Conclusion
VAEB is a patient‐preferred, safe, well‐tolerated, lower‐cost alternative to DOB for definitive diagnosis of selected B3 breast lesions.
