European guidelines for the diagnosis, treatment and follow-up of breast lesions with uncertain malignant potential (B3 lesions) developed jointly by EUSOMA, EUSOBI, ESP (BWG) and ESSO. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:107292. [PMID: 38061151 DOI: 10.1016/j.ejso.2023.107292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 11/17/2023] [Indexed: 01/16/2024]
Abstract
INTRODUCTION Breast lesions of uncertain malignant potential (B3) include atypical ductal and lobular hyperplasias, lobular carcinoma in situ, flat epithelial atypia, papillary lesions, radial scars and fibroepithelial lesions as well as other rare miscellaneous lesions. They are challenging to categorise histologically, requiring specialist training and multidisciplinary input. They may coexist with in situ or invasive breast cancer (BC) and increase the risk of subsequent BC development. Management should focus on adequate classification and management whilst avoiding overtreatment. The aim of these guidelines is to provide updated information regarding the diagnosis and management of B3 lesions, according to updated literature review evidence. METHODS These guidelines provide practical recommendations which can be applied in clinical practice which include recommendation grade and level of evidence. All sections were written according to an updated literature review and discussed at a consensus meeting. Critical appraisal by the expert writing committee adhered to the 23 items in the international Appraisal of Guidelines, Research and Evaluation (AGREE) tool. RESULTS Recommendations for further management after core-needle biopsy (CNB) or vacuum-assisted biopsy (VAB) diagnosis of a B3 lesion reported in this guideline, vary depending on the presence of atypia, size of lesion, sampling size, and patient preferences. After CNB or VAB, the option of vacuum-assisted excision or surgical excision should be evaluated by a multidisciplinary team and shared decision-making with the patient is crucial for personalizing further treatment. De-escalation of surgical intervention for B3 breast lesions is ongoing, and the inclusion of vacuum-assisted excision (VAE) will decrease the need for surgical intervention in further approaches. Communication with patients may be different according to histological diagnosis, presence or absence of atypia, or risk of upgrade due to discordant imaging. Written information resources to help patients understand these issues alongside with verbal communication is recommended. Lifestyle interventions have a significant impact on BC incidence so lifestyle interventions need to be suggested to women at increased BC risk as a result of a diagnosis of a B3 lesion. CONCLUSIONS These guidelines provide a state-of-the-art overview of the diagnosis, management and prognosis of B3 lesions in modern multidisciplinary breast practice.

Abstract
PURPOSE 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.

Potential role of vacuum-assisted procedures in resecting breast cancers and highlighting selection criteria to support future trials. Front Oncol 2023; 13:1239574. [PMID: 37810980 PMCID: PMC10552518 DOI: 10.3389/fonc.2023.1239574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 08/03/2023] [Indexed: 10/10/2023] Open
Abstract
Purpose The purpose of this study was to evaluate the role of vacuum-assisted biopsy (VAB) in resecting breast cancers. Methods Retrospective database analysis of 116 cancers [both invasive breast cancers (IC) and ductal carcinoma in situ (DCIS)] diagnosed by VAB submitted to standard surgical treatment with complete histological data from VAB and surgery. Excision following VAB was defined as complete resection (CR) if there was no residual tumor in the surgical specimen, minimal residual disease (MRD) if residual tumor ≤ 3 mm, gross residual disease (GRD) if residual tumor > 3 mm, and upgrade from DCIS on VAB to IC. CR and MRD were combined as potentially resected percutaneously (PRP). GRD and those with upgrade to IC were determined not eligible for percutaneous resection (NPR). Factors predictive of PRP were evaluated. Results Mean age was 55.6 years (20-91; SD: 12,27). CR was seen in 29 of 116 cases (25%), MRD in 18 of 116 cases (15.5%), GRD in 64 of 116 cases (55.2%), and five of 116 cases (4.3%) were upgraded from DCIS to IC, and those groups combined represented 47 cases of PRP (40.5%) and 69 (59,5%) of NPR. For 77 tumors ≤ 10 mm, 45 (58.5%) were PRP. Multivariate analysis reveals significance for enlarged VAB (EVAB) (p = 0.008, OR: 4.4, 95% CI), low/intermediate nuclear grade (p < 0.001, OR: 12.5, 95% CI) and final tumor size (T) ≤ 10 mm (p = 0.001, OR: 50.1, 95% CI) for PRP. Conclusions This study showed that lesions completely excised with VAB that were cancer could have been treated with VAB rather than surgery but tumor selection in terms of subtype and size is important.

[PMID: 37330436 DOI: 10.1007/s00428-023-03566-x] [Citation(s) in RCA: 16] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 05/01/2023] [Accepted: 05/17/2023] [Indexed: 06/19/2023]
Abstract
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.

Abstract
PURPOSE In recent years vacuum-assisted excision (VAE) has been described as an alternative treatment for some B3 lesions. This study aims to assess the effectiveness of using VAE to manage selected B3 lesions by quantifying the number of B3 lesions undergoing VAE, the malignant upgrade rate, and the complications encountered. MATERIALS AND METHODS Our department evaluated all B3 lesions diagnosed between January 2019 and October 2021 and treated them with VAE. The data were collected during the initial biopsy and final histology based on VAE image guidance, also considering initial lesions and complications. The exclusion criteria were: B3 lesion of size > 20 mm, presence of a concomitant malignant lesion, lesion < 5.0 mm distant from the skin, nipple or pectoral muscle, phyllodes tumours or indeterminate B3 lesions. Lesions that upgraded to malignancy underwent surgical excision, while benign lesions performed radiological follow-ups. RESULTS From 416 B3 lesions diagnosed, 67 (16.1%) underwent VAE. VAE was performed under X-ray (50/67) or ultrasound guidance (17/67). Five cases (7.5%) upgraded to a malignant lesion, 2 ADH, 2 LIN and one papillary lesion that underwent surgery. No malignancy or new lesions has occurred at the site of the VAE, with an average radiological follow-up of 14.9 months. CONCLUSIONS VAE could be a safe and effective pathway for managing selected B3 lesions. Lesions initially subjected to CNB with ADH and LN outcome, before undergoing VAE, should perform a VAB for better tissue characterization and management.

Abstract
B3 lesions of the breast are a heterogeneous group of lesions with uncertain malignant potential encompassing a broad spectrum of histologically distinct alterations that often pose challenging decisions if diagnosed on the preoperative core or vacuum biopsies. B3 lesions are mostly detected due to mammographic calcifications or mass lesions and, in most cases, encompass a spectrum of atypical lesions such as atypical ductal hyperplasia, classic lobular neoplasia, flat epithelial atypia, papillomas, fibroepithelial tumors, and rarely other lesions such as mucocele-like lesions, atypical apocrine lesions, and rare stromal proliferations. The use of immunohistochemical stains (estrogen receptors, basal cytokeratin, myoepithelial markers, and stromal marker panel) is useful in the differentiation of these lesions and allowing proper classification. Regarding clinical management of B3 lesions, the radiological-pathological correlation of the given entity plays the most important key element for the proper next diagnostic and therapeutic step.

The positive predictive value of vacuum assisted biopsy (VAB) in predicting final histological diagnosis for breast lesions of uncertain malignancy (B3 lesions): A systematic review & meta-analysis. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 48:1464-1474. [PMID: 35491362 DOI: 10.1016/j.ejso.2022.04.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/22/2022] [Accepted: 04/08/2022] [Indexed: 10/18/2022]
Abstract
INTRODUCTION High-risk or B3 breast lesions are considered lesions of uncertain malignant potential and comprise between 5 and 12% of initial biopsy results. We sought to perform a systematic review and meta-analysis of studies published within the last twenty years to determine the pooled Positive Predictive Value (PPV) of VAB in selected B3 lesions. METHODS The study report is based on the guidelines of PRISMA and Meta-Analysis of Observational Studies in Epidemiology. OUTCOMES The primary outcome of this study was to determine the PPV of VAB in determining final histological diagnosis in B3 breast lesions using pooled estimates. The secondary outcomes were to determine if needle gauge or the re-classification of Lobular Carcinoma in Situ(LCIS) introduced in 2012 influenced pooled estimates. RESULTS 78 studies incorporating 6,377 B3 lesions were included in this review, 1214 of which were upgraded to DCIS or invasive malignancy following surgical excision(19%). The pooled PPV of VAB in Atypical Ductal Hyperplasia(ADH) and Lobular Neoplasia(LN) were 0.79(CI 0.76-0.83) and 0.84(CI 0.8-0.88). VAB of Flat Epithelial Atypia(FEA), radial scar and papillary lesions with/without atypia all had a pooled PPV >90% (underestimation rates 7%, 1%, 5% and 3% respectively). Needle gauge size and the change in LCIS classification did not appear to influence underestimation rates on subgroup analysis. CONCLUSION Results from this meta-analysis suggests it is reasonable to perform VAB as definitive treatment for certain B3 lesions, specifically LN, FEA, radial scar, and papillary lesions when specific criteria are fulfilled. Surgical excision should continue as the mainstay of treatment for ADH.

Abstract
PURPOSE 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). MATERIAL AND 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. CONCLUSION 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.

Abstract
Abstract
Purpose of Review
The introduction of mammographic screening programmes has resulted increasing numbers of women with small breast cancers with biologically favourable characteristics. Many of these cancers may represent overdiagnosis, with a resulting treatment burden for women and healthcare costs for providers. Here, current surgical approaches to the treatment of such tumours are reviewed, together with alternative approaches to their management.
Recent Findings
The surgical treatment of small, screen-detected breast cancers with biologically favourable characteristics has been extrapolated from the management of symptomatic breast cancers. There is no prospective randomised evidence for conventional open surgery compared with other approaches in this setting. A number of minimally invasive techniques, most notable vacuum-assisted excision, have been described for the management of these tumours, but at present, there is a lack of high-quality evidence to support their routine use. There are currently ongoing randomised trials evaluating risk-adapted surgical and minimally invasive approaches to the management of good prognosis disease.
Summary
It is possible that the surgical treatment of good prognosis screen-detected breast cancers may be de-escalated. However, high-quality evidence from ongoing prospective randomised trials will be required in order to change clinical practice.
