Abstract
The vast majority of image-detected breast abnormalities are diagnosed by percutaneous core needle biopsy (CNB) in contemporary practice. For frankly malignant lesions diagnosed by CNB, the standard practice of excision and multimodality therapy have been well-defined. However, for high-risk and selected benign lesions diagnosed by CNB, there is less consensus on optimal patient management and the need for immediate surgical excision. Here we outline the arguments for and against the practice of routine surgical excision of commonly encountered high-risk and selected benign breast lesions diagnosed by CNB. The entities reviewed include atypical ductal hyperplasia, atypical lobular hyperplasia, lobular carcinoma in situ, intraductal papillomas, and radial scars. The data in the peer-reviewed literature confirm the benefits of a patient-centered, multidisciplinary approach that moves away from the reflexive "yes" or "no" for routine excision for a given pathologic diagnosis.

Rethinking Routine Surgical Excision for all Radial Sclerosing Lesions of the Breast. J Surg Res 2022; 279:611-618. [PMID: 35926311 DOI: 10.1016/j.jss.2022.06.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 06/10/2022] [Accepted: 06/28/2022] [Indexed: 11/22/2022]
Abstract
INTRODUCTION The need for routine surgical excision of a radial sclerosing lesions (RSL) of the breast identified on percutaneous biopsy remains controversial, as contemporary upgrade rates are lower than historically cited. MATERIALS AND METHODS A prospectively-maintained database of high-risk breast biopsies undergoing multidisciplinary review at a single institution was queried to identify cases of RSL from 2/2015 to 11/2020. Demographic, radiologic, and pathologic variables were summarized using frequencies and analyzed in association with RSL excision status using mixed-effects logistic regression or Fisher's exact tests. RESULTS 217 RSL were identified, diagnosed at a mean age of 57 y. The median imaging size was 1.3 cm and the majority had estimated >50% of the target removed by core needle biopsy. 32.3% underwent surgical excision of the RSL biopsy site and 2/70 (2.9%) upgraded to ductal carcinoma in situ (DCIS) on final surgical pathology. Upgrade was significantly higher for atypical RSL (P = 0.02). None of the RSL (n = 60) without atypia who had undergone excision were upgraded. For those omitting surgical excision, there was no subsequent breast cancer diagnosis at the RSL site over a mean follow-up of 23 mo. CONCLUSIONS Surgical excision may be omitted for RSL without atypia as this group has 0% risk of upgrade after multidisciplinary review.

Radiomics Based on DCE-MRI Improved Diagnostic Performance Compared to BI-RADS Analysis in Identifying Sclerosing Adenosis of the Breast. Front Oncol 2022; 12:888141. [PMID: 35646630 PMCID: PMC9133496 DOI: 10.3389/fonc.2022.888141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 04/12/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose Sclerosing adenosis (SA) is a benign lesion that could mimic breast carcinoma and be evaluated as malignancy by Breast Imaging-Reporting and Data System (BI-RADS) analysis. We aimed to construct and validate the performance of radiomic model based on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) compared to BI-RADS analysis to identify SA. Methods Sixty-seven patients with invasive ductal carcinoma (IDC) and 58 patients with SA were included in this retrospective study from two institutions. The 125 patients were divided into a training cohort (n= 88) from institution I and a validation cohort from institution II (n=37). Dynamic contrast-enhanced sequences including one pre-contrast and five dynamic post-contrast series were obtained for all cases with different 3T scanners. Single-phase enhancement, multi-phase enhancement, and dynamic radiomic features were extracted from DCE-MRI. The least absolute shrinkage and selection operator (LASSO) logistic regression and cross-validation was performed to build the radscore of each single-phase enhancement and the final model combined multi-phase and dynamic radiomic features. The diagnostic performance of radiomics was evaluated by receiver operating characteristic (ROC) analysis and compared to the performance of BI-RADS analysis. The classification performance was tested using external validation. Results In the training cohort, the AUCs of BI-RADS analysis were 0.71 (95%CI [0.60, 0.80]), 0.78 (95%CI [0.67, 0.86]), and 0.80 (95%CI [0.70, 0.88]), respectively. In single-phase analysis, the second enhanced phase radiomic signature achieved the highest AUC of 0.88 (95%CI [0.79, 0.94]) in distinguishing SA from IDC. Nine multi-phase radiomic features and two dynamic radiomic features showed the best predictive ability for final model building. The final model improved the AUC to 0.92 (95%CI [0.84, 0.97]), and showed statistically significant differences with BI-RADS analysis (p<0.05 for all). In the validation cohort, the AUC of the final model was 0.90 (95%CI [0.75, 0.97]), which was higher than all BI-RADS analyses and showed statistically significant differences with one of the BI-RADS analysis observers (p = 0.03). Conclusions Radiomics based on DCE-MRI could show better diagnostic performance compared to BI-RADS analysis in differentiating SA from IDC, which may contribute to clinical diagnosis and treatment.

Abstract
BACKGROUND We assessed the cancer upstage rate of Radial Scars (RS), and Complex Sclerosing Lesions (CSL), and risk-stratified lesions based on radiological and pathological features. METHODS Characteristics of RS/CSL treated from 2013 to 2018 were examined for features associated with cancer. RESULTS 78 RS/CSL were found on core needle biopsy (CNB) and surgically excised. 9 (11.5%) lesions were upstaged. Upstaged patients were older (66 vs 51, p = 0.033). More upstaged lesions were accompanied by a mass on both mammography (87.5% vs. 30.0%, p = 0.005) and ultrasound (100.0% vs. 62.8%, p = 0.043). 20.5% of lesions biopsied under ultrasound guidance with small needles (14-18G) were upstaged, but no lesions biopsied under stereotactic guidance with large needles (9-12 G) with vacuum assistance were upstaged (p = 0.009). CONCLUSIONS Excision of RS/CSL seen on CNB is warranted, especially if the patient is older, the CNB is performed under ultrasound guidance with small needles, or if a mass is present on imaging.

Radial Scars and Complex Sclerosing Lesions of the Breast: Prevalence of Malignancy and Natural History Under Active Surveillance. Ann Surg Oncol 2021; 28:5149-5155. [PMID: 33666811 DOI: 10.1245/s10434-021-09713-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Accepted: 01/27/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND When needle core biopsies (NCBs) of the breast reveal radial scar or complex sclerosing lesions (RSLs), excision is often recommended despite a low risk of malignancy in the modern era. The optimal management of NCBs revealing RSLs is controversial, and understanding of the natural history of unresected RSLs is limited. METHODS We retrospectively analyzed pathology and imaging data from 148 patients with NCB revealing RSL without atypia from 2015 to 2019 to determine the prevalence of malignancy and the behavior of RSLs undergoing active surveillance (AS). RESULTS The mean age of patients was 52 years, and most lesions were screen-detected (91%). The median lesion size was 6.0 mm (range 2-39). Most patients (66%, n = 98) underwent immediate surgery, while 34% (n = 50) of patients underwent AS, with a median follow-up of 16 months (range 6-51). Of the excised RSLs, 99% (n = 97) were benign and 1% (n = 1) revealed ductal carcinoma in situ (DCIS). In 17% (n = 17) of cases, additional high-risk lesions were discovered upon excision. Among the 50 patients undergoing AS, no lesions progressed on interval imaging. CONCLUSIONS In this cohort, 99% of RSLs undergoing excision were benign, 1% revealed DCIS, and there were no invasive cancers. In the first study of patients with RSLs undergoing AS, we found that all lesions either remained stable or resolved. We propose that the vast majority of patients with RSL on NCB can be safely offered AS, and that routine excision is a low-value intervention.

Histopathology 2019; 75:900-915. [PMID: 31286532 DOI: 10.1111/his.13950] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 06/10/2019] [Accepted: 07/04/2019] [Indexed: 11/30/2022]
Abstract
AIMS The diagnosis of radial scars/complex sclerosing lesions (RSs/CSLs) onpercutaneous biopsy carries a risk of histological underestimation. Consequently, surgical excision is often performed in order to exclude a possible associated malignancy. The aim of this study was to assess the rate of 'upgrade to carcinoma' upon subsequent surgical excision of RS/CSL cases diagnosed on vacuum-assisted large-core biopsy (VALCB). We also analysed the risk factors for upgrade in order to determine a subset of patients who could avoid surgery and benefit from conservative management with clinical and imaging follow-up. METHODS AND RESULTS This was a retrospective observational single-centre study on 174 consecutive RS/CSL cases diagnosed on VALCB from May 2008 to October 2015. Univariate analysis was performed to identify clinical, radiological and histological risk factors for upgrade. Surgical excision was performed following VALCB diagnosis of 88 RS/CSL cases with or without associated atypia. The overall rate of surgical upgrade to carcinoma was 9.1% (8/88). None of the benign biopsies without atypia was surgically upgraded. Additional to atypia, risk factors for upgrade were non-incidental finding of the RS/CSL, the mammographic appearance, and the number of fragments obtained during the biopsy procedure (P < 0.05). CONCLUSION We demonstrate that VALCB revealing an RS/CSL is reliable for excluding malignancy when there is no associated atypia and when radiological and histological findings are concordant. In such cases, surgery can be avoided in favour of clinical and imaging follow-up. When an RS/CSL is associated with atypia, the decision to perform surgical excision depends on other associated risk factors.

Abstract
PURPOSE Radial scar's stellate appearance may mimic carcinoma mammographically and histologically. Management of radial scar (RS) found on breast core needle biopsies (CNB) ranges from excision to clinical observation due to the variation in reported upgrades to malignancy at surgical excision. We examined the upgrade rate in patients with RS detected on CNB at our institution and reviewed the current literature. METHODS A retrospective study was conducted of all cases with RS diagnosed on CNB between December 2006 and March 2017 at our institution. Inclusion criteria were patients with "pure" RS and RS associated with high-risk lesions (HRL). Upgrade was defined as invasive or non-invasive cancer in the excisional biopsy. RESULTS 157 cases were identified with RS on CNB, and 122 cases met inclusion criteria. Of these 122 cases, 91 (75%) had pure RS on CNB while 31 (25%) had associated atypia or HRL. 81 (66%) of patients proceeded to excisional biopsy and 41 (34%) did not. Two patients (1.6% of total) were found to have a low-grade invasive ductal carcinoma (0.6 and 0.8 cm) upon surgical excision. None of the remaining 120 patients developed an ipsilateral breast cancer with a mean of 32.3-month follow-up. CONCLUSIONS We found a very low upgrade rate to breast cancer when RS was found on CNB with or without associated HRL. Our results are consistent with other reported series. Our data do not support surgical excision for RS but rather close clinical follow-up for patients with RS on CNB.
