UNASSIGNED: This is a systematic review and meta-analysis comparing surgical excision with percutaneous ultrasound-guided vacuum-assisted excision (US-VAE) for the treatment of benign phyllodes tumor (PT) using local recurrence (LR) as the endpoint.
UNASSIGNED: To determine the frequency of local recurrence (LR) of benign phyllodes tumor (PT) after ultrasound-guided vacuum-assisted excision (US-VAE) compared to the frequency of LR after surgical excision.
UNASSIGNED: A systematic review and meta-analysis [following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard] was conducted by comparing LR in women older than 18 years treated for benign PT by US-VAE compared with local surgical excision with at least 12 months of follow-up. Studies were retrieved from PubMed, Scopus, Web of Science, and Embase. The pooled effect measure used was the odds ratio (OR) of recurrence.
UNASSIGNED: Five comparative prospective or retrospective observational studies published between January 1, 1992, and January 10, 2022, comparing surgical excision with percutaneous US-VAE for LR of benign PT met the selection criteria. Four were retrospective observational cohorts, and one was a prospective observational cohort. A total of 778 women were followed up. Of them, 439 (56.4%) underwent local surgical excision, and 339 (43.6%) patients had US-VAE. The median age of patients in the five studies ranged from 33.7 to 39 years; the median size ranged from 1.5 cm to 3.0 cm, and the median follow-up ranged from 12 months to 46.6 months. The needle gauge ranged from 7G to 11G. LR rates were not statically significant between US-VAE and surgical excision (41 of 339 versus 34 of 439; OR 1.3; p = 0.29).
UNASSIGNED: This meta-analysis suggests that using US-VAE for the removal of benign PT does not increase local regional recurrence and is a safe minimally invasive therapeutic option.

This article highlights the recent publications and changing trends in practice regarding management of high-risk lesions of the breast. Traditional management has always been a surgical operation but this is recognized as overtreatment. It is recognized that overdiagnosis is inevitable but what we can control is overtreatment. Vacuum-assisted excision is now established as an alternative technique to surgery for further sampling of these high-risk lesions in the United Kingdom. Guidelines from the United Kingdom and Europe now recognize this alternative pathway, and data are available showing that vacuum-assisted excision is a safe alternative to surgery.

OBJECTIVE: Benign breast masses represent a substantial proportion of breast cancer screening results and may require multiple follow-up visits and biopsy. Even with a preceding benign core biopsy, benign masses have been excised via open surgery for a variety of reasons. This study compared the procedural costs of US-guided vacuum-assisted excision (US-VAE) versus open surgical excisions for benign breast masses and high-risk lesions (HRL).
METHODS: In this retrospective cohort study, female outpatients receiving US-VAE or open excision of benign breast masses between 2015 and 2018 were identified within the Premier Healthcare Database. A secondary analysis was conducted for patients with HRLs. Propensity score matching and multivariate regression adjusted for patient demographics, encounter level covariates, and hospital characteristics. The total procedural costs were reported from a hospital perspective.
RESULTS: A total of 33 724 patients underwent excisions for benign breast masses (8481 US-VAE and 25 242 open surgery). Procedural costs were significantly lower in unmatched patients who received US-VAE ($1350) versus open surgery ($3045) (P < 0.0001). After matching, a total of 5499 discharges were included in each group, with similar findings for US-VAE ($1348) versus open surgery ($3101) (P < 0.0001). A secondary analysis of matched HRL patients (41 discharges in each group) also showed significantly lower procedural costs with US-VAE ($1620) versus open surgery ($3870) (P < 0.0001).
CONCLUSIONS: Among patients with benign breast masses or HRLs, US-VAE was associated with significantly lower procedural costs versus open surgery. If excision is performed and expected clinical outcomes are equal, US-VAE is preferable to reduce costs without compromising the quality of care.

Breast cancer screening programmes frequently detect early, good prognosis breast cancers with significant treatment burden for patients, and associated health-cost implications. Emerging evidence suggests a role for minimally invasive techniques in the management of these patients enabling many women to avoid surgical intervention. Minimally invasive techniques include vacuum-assisted excision, cryoablation, and radiofrequency ablation. We review published evidence in relation to the risks and benefits of each technique and discuss ongoing trials. Data to date are promising, and we predict a trend towards minimally invasive treatment for early, good-prognosis breast cancer as technical skills, suitability criteria, and follow-up protocols are established.

OBJECTIVE: The purpose of this study was to evaluate if it is possible to completely remove small breast cancer tumours with vacuum-assisted excision (VAE) under ultrasound guidance.
METHODS: Women ≥ 50 years old with a biopsy proven invasive cancer ≤ 10 mm were selected between October 2021 and November 2021 based on referrals and enrolled in this prospective study. The patients underwent VAE within six weeks following biopsy to remove the tumour. After the tumour was excised and the biopsy cavities margins were shaved, a radioactive seed was inserted into the biopsy cavity. The VAE excision cavity and surrounding tissue were surgically excised. Preliminary VAE results were evaluated after ten patients. For the study to proceed at least 80 % of the breast cancer tumours had to be completely removed by VAE.
RESULTS: The tumours median size in mammography was 8.5 mm (6-9 mm) and in ultrasound 6.5 mm (4-9 mm). The shape of the lesion was round in three (30 %), oval in two (20 %) and irregular in five (50 %) patients. None of the tumours were completely removed in the first VAE specimen, meaning that there was invasive cancer or ductal carcinoma in situ (DCIS) in the \"shaved margins\" and/or the surgical specimen. In five (50 %) cases, the surgical specimen was free of invasive cancer and DCIS.
CONCLUSIONS: None of the small invasive breast cancers were completely excised with VAE under ultrasound guidance, therefore it is not a reliable method to remove small breast cancers.

OBJECTIVE: To evaluate the technical success and efficacy rates of US-guided percutaneous vacuum-assisted excision (VAE) of breast fibroadenomas, also assessing procedural complications and long-term patient satisfaction rates.
METHODS: The institutional database of a tertiary breast cancer referral centre was retrospectively reviewed to retrieve all women with fibroadenomas who underwent US-guided VAE between May 2011 and September 2019. We subsequently included in this study all fibroadenomas with a maximum diameter of 3 cm at US and an available histological confirmation obtained by core-needle biopsy before VAE. Immediately after VAE, technical success (defined as the correct VAE execution) and the occurrence of procedural complications were evaluated. Imaging follow-up (US ± mammography) after 6, 12, 24 and 36 months was performed to evaluate technical efficacy (defined as the absence of fibroadenoma recurrence at 6-month follow-up). Long-term patient satisfaction was evaluated with telephonic interviews in October 2022.
RESULTS: We retrospectively included 108 women (median age 46 years) with 110 fibroadenomas diagnosed at core-needle biopsy with a median lesion size at US of 12 mm. Technical success was obtained in 110/110 VAEs (100%). Minor procedural complications (haematomas) occurred in 7/110 VAEs (6%), whereas 8/110 patients had a fibroadenoma recurrence at 6-month follow-up, resulting in a 93% technical efficacy (102/110 VAEs). All patients available for telephonic follow-up (104/104, 100%) reported high satisfaction with VAE results.
CONCLUSIONS: US-guided VAE is a safe and effective procedure for the excision of fibroadenomas, representing a viable alternative to surgery, with a low complication rate and high patient satisfaction.

The heterogeneous group of B3 lesions in the breast harbors lesions with different malignant potential and progression risk. As several studies about B3 lesions have been published since the last Consensus in 2018, the 3rd International Consensus Conference discussed the six most relevant B3 lesions (atypical ductal hyperplasia (ADH), flat epithelial atypia (FEA), classical lobular neoplasia (LN), radial scar (RS), papillary lesions (PL) without atypia, and phyllodes tumors (PT)) and made recommendations for diagnostic and therapeutic approaches. Following a presentation of current data of each B3 lesion, the international and interdisciplinary panel of 33 specialists and key opinion leaders voted on the recommendations for further management after core-needle biopsy (CNB) and vacuum-assisted biopsy (VAB). In case of B3 lesion diagnosis on CNB, OE was recommended in ADH and PT, whereas in the other B3 lesions, vacuum-assisted excision was considered an equivalent alternative to OE. In ADH, most panelists (76%) recommended an open excision (OE) after diagnosis on VAB, whereas observation after a complete VAB-removal on imaging was accepted by 34%. In LN, the majority of the panel (90%) preferred observation following complete VAB-removal. Results were similar in RS (82%), PL (100%), and FEA (100%). In benign PT, a slim majority (55%) also recommended an observation after a complete VAB-removal. VAB with subsequent active surveillance can replace an open surgical intervention for most B3 lesions (RS, FEA, PL, PT, and LN). Compared to previous recommendations, there is an increasing trend to a de-escalating strategy in classical LN. Due to the higher risk of upgrade into malignancy, OE remains the preferred approach after the diagnosis of ADH.

OBJECTIVE: To compare the safety and therapeutic effect of ultrasound (US)-guided microwave ablation (MWA) and US-guided vacuum-assisted excision (VAE) for patients with B3 lesions of the breast.
METHODS: Patients who underwent US-guided MWA or US-guided VAE at Sichuan Tumor Hospital from January 2016 to December 2021 were retrospectively analyzed. The technical success rate and residual rate of the two minimally invasive surgeries were recorded. During follow-up, differences in symptom relief, recurrence or progression, re-intervention, incidence of adverse events, or personal satisfaction were observed between the two groups.
RESULTS: The follow-up time was comparable between the two groups. The technical success rate was similar between the two groups; no residue was found in the US-guided MWA group, and the residue rate in the US-guided VAE group was 3.4%. The symptoms of the two groups were improved after the operation. The incidence of postoperative adverse events in the US-guided MWA group was significantly lower than that in the US-guided VAE group. Additionally, the MWA group had a lower incidence of adverse events when the tumor diameter was >2.5 cm. Compared to the US-guided VAE group, the US-guided MWA group had a lower rate of tumor recurrence or progression, re-intervention rate, and higher personal satisfaction.
CONCLUSIONS: The technical success rate of US-guided MWA for B3 lesions was comparable to that of US-guided VAE, but US-guided MWA had a lower incidence of adverse events and a higher degree of personal satisfaction compared with US-guided VAE.

Background  Fibroadenoma is one of the most common benign breast lesions that is frequently surgically excised in breast practice. Aim  The aim of this study was to determine the efficacy and safety of ultrasound-guided (USG) vacuum-assisted excision biopsy (VAEB) of fibroadenoma. Settings and Design  A retrospective observational study. Methods and Materials  A total of 113 patients with 163 fibroadenomas who underwent USG-guided VAEB under local anesthesia with 7G and 10G probes using an Encor Enspire equipment were included in the study. The patients were followed up after 1, 6, and 12 months. The fibroadenomas up to 4 cm were excised as per the U.S. Food and Drug Administration-approved guidelines of the American Society of Surgeons for percutaneous removal of benign breast lesions. Results  The percentage of complete excision rate was 98.8% and the most frequent complication encountered was hematoma including immediate and delayed accounting for 3.06%. There were no recurrent lesions in our study. Conclusion  USG-guided VAEB of benign breast lumps can be a safe and effective alternative to surgical excision and had better patient satisfaction in terms of efficacy and cosmesis.

OBJECTIVE: Nowadays, surgical excision is no longer justified for all B3 lesions and a minimally-invasive therapeutic treatment has been encouraged. The aim of this study was to evaluate the feasibility and the therapeutic efficacy of ultrasound-guided vacuum-assisted excision (US-VAE) for the treatment of selected breast lesions of uncertain malignant potential (B3).
METHODS: From July 2018 to December 2019, 11/48 breast lesions classified as B3 after ultrasound-guided core needle biopsy were treated with US-VAE in our Institution. Inclusion criteria were: B3 nodules ultrasonographically detectable for which VAE is recommended by international guidelines2, size ranging between 5 and 25 mm, circumscribed margins, and lesion position at least 5 mm from the skin and the nipple. A radiological follow-up to evaluate the completeness of excision, the presence of post-procedural hematoma or of residual disease/recurrence was performed after 10 and 30 days and 6 and 12 months. 12-month ultrasound was considered the gold standard. All patients were asked to complete a satisfaction survey and a full assessment of the costs of US-VAE was performed.
RESULTS: Complete excision was achieved in 81.8% of US-VAE. No lesions were upgraded to carcinoma and no patients had to undergo surgery. No complications occurred during or after US-VAE. All patients were satisfied with the procedure and the cosmetic result (100%). US-VAE cost approximately 422 Euros per procedure.
CONCLUSIONS: US-VAE has proven to be an optimal tool for the therapeutic excision of selected B3 lesions, with high success rate, good patient compliance and considerable money savings compared to surgery. This technique has the potential to reduce unnecessary surgery and healthcare costs.
