Background: Patients newly diagnosed with breast cancer face a series of complex decisions regarding locoregional and systemic treatment. There is a need to improve the quality of locoregional and systemic decisions for breast cancer patients, and to help patients understand the role of evaluative tests in this decision process. We are now conducting a randomized controlled trial (RCT) of an online decision tool-called iCanDecide, which we expect will help patients with these difficult decisions...

INTRODUCTION: Due to the possibility of underestimation, surgical excision is usually offered to patients with atypical ductal hyperplasia (ADH) diagnosed with core needle biopsy (CNB). Here we review the 10-year data of patients with ADH diagnosed by CNB, aiming to identify the factors associated with under-diagnosis. METHODS: Retrospective review of database from 1st Jan 2005 to 31st Dec 2014 was performed; patients with ADH diagnosed by CNB were identified. Diagnosis upgrade rate and its risk factors were evaluated...

BACKGROUND: Collagen fibers surrounding breast ducts may influence breast cancer progression. Syndecan-1 interacts with constituents in the extracellular matrix, including collagen fibers, and may contribute to cancer cell migration. Thus, the orientation of collagen fibers surrounding ductal carcinoma in situ (DCIS) lesions and stromal syndecan-1 expression may predict recurrence. METHODS: We evaluated collagen fiber alignment and syndecan-1 expression in 227 women diagnosed with DCIS in 1995-2006 followed through 2014 (median 14...

The objective was to determine the 10-year oncological safety of nipple-sparing mastectomy (NSM) in patients diagnosed with ductal carcinoma in situ (DCIS). The use of NSM preserves the nipple-areola complex (NAC). As residual fibroglandular breast tissue can remain behind the spared NAC, its use for patient with breast cancer is controversial. The oncologic outcomes and complication rates after performing NSM compared to other techniques are still under debate and a concern when treating patients with breast cancer...

To evaluate the MR appearance of noncalcified ductal carcinoma in situ (DCIS), with comparison to calcified DCIS. A retrospective, IRB-approved review of all DCIS diagnosed via MR biopsy between 2007 and 2011 was performed. DCIS was categorized as noncalcified based on the absence of calcifications on mammography and specimen radiography. MR morphology (focus, mass, nonmass enhancement [NME]) and enhancement kinetics (initial and delayed) for noncalcified DCIS were recorded and compared based on nuclear grade (1-3), size (<1...

The significance and regulation of liver receptor homologue 1 (LRH-1, NR5A2), a tumour-promoting transcription factor in breast cancer cell lines, is unknown in clinical breast cancers. This study aims to determine LRH-1/NR5A2 expression in breast cancers and relationship with DNA methylation and tumour characteristics. In The Cancer Genome Atlas breast cancer cohort NR5A2 expression was positively associated with intragenic CpG island methylation (1.4-fold expression for fully methylated versus not fully methylated, p=0...

Ductal carcinoma in situ (DCIS) is the most common form of breast cancer, with 50,000 cases diagnosed every year in the United States. Over-treatment and under-treatment remain significant clinical challenges in patient care. Identifying key mechanisms associated with DCIS progression could uncover new biomarkers to better predict patient prognosis and improve guided treatment. Chemokines are small soluble molecules that regulate cellular homing through molecular gradients. CCL2-mediated recruitment of CCR2+ macrophages are a well-established mechanism for metastatic progression...

REVIEW

The management of ductal carcinoma in situ (DCIS) has traditionally followed the evidence base for invasive breast cancer using surgery, radiation therapy, and drug therapy to remove the DCIS from the breast and reduce the risk of recurrence for both DCIS and invasive breast cancer. Because of concerns regarding the overtreatment of DCIS, randomized controlled trials have been established to test the outcomes (invasive breast cancer outcomes and patient-reported outcome measures) of active surveillance compared with guideline-concordant care for low-risk (for progression) DCIS...

BACKGROUND AND OBJECTIVES: The impact of preoperative magnetic resonance imaging (pMRI) and cavity shave margins (CSM) on re-excision rate (RR) in DCIS is unclear. We investigated whether either modality was associated with RR in DCIS. METHODS: This is a single-institution retrospective study of 295 women undergoing breast conservation surgery for pure DCIS (2010-2013). CSM were the systematic resection of 4-6 margins during lumpectomy whereas selective shave margins (SSM) were the selective resection of 1-3 margins...

BACKGROUND AND OBJECTIVES: More extensive surgical treatments for early stage breast cancer are increasing. The patterns of preoperative MRI overall and by stage for this trend has not been well established. METHODS: Using Breast Cancer Surveillance Consortium registry data from 2010 through 2014, we identified women with an incident non-metastatic breast cancer and determined use of preoperative MRI and initial surgical treatment (mastectomy, with or without contralateral prophylactic mastectomy (CPM), reconstruction, and breast conserving surgery ± radiation)...

Background: Anastrozole reduces breast cancer risk in women at high risk, but implementing preventive therapy in clinical practice is difficult. Here, we evaluate adherence to anastrozole in the International Breast Cancer Intervention Study (IBIS) II prevention and Ductal Carcinoma in Situ (DCIS) trials, and its association with early symptoms. Patients and methods: In the prevention trial, 3864 postmenopausal women were randomized to placebo vs. anastrozole. 2980 postmenopausal women with DCIS were randomized to tamoxifen vs...

PURPOSE: Microcalcifications are a common finding in mammography and usually require invasive procedures to diagnose or exclude malignancy. As many microcalcifications are due to benign lesions, we wanted to assess whether breast MRI as an additional diagnostic tool may be used to distinguish benign from malignant in this setting. MATERIALS AND METHODS: Eligible for this retrospective, IRB-approved observational study were 858 consecutive patients (mean age 54±11years) undergoing stereotactically-guided biopsies of suspicious mammographic microcalcifications during three year at our institution...

BACKGROUND: Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of epithelial cells which is confined within the basement membrane of the mammary ductal-lobular system. It is of interest to determine to what extent the potential to metastasize increases for DCIS patients when the basement membrane is breached (i.e. microinvasion is present). METHODS: We retrieved the records of 525,395 women who had either first primary DCIS or small (≤ 2.0 cm) node-negative invasive breast cancer in the Surveillance, Epidemiology and End Results (SEER) registries database (1990-2013)...

A 26-year-old woman presented with a slow-growing right breast lump. Excision biopsy of the lump showed invasive ductal carcinoma with adjacent ductal carcinoma in situ (DCIS). Preoperative imaging was performed to assess the extent of disease. Magnetic resonance (MR) imaging of the breasts showed an area of clustered ring enhancement deep to the biopsy site, which was representative of residual DCIS. DCIS is a common noninvasive malignancy that manifests as a primary breast tumour or in association with other lesions...

REVIEW
Kylie L Gorringe, Stephen B Fox
Ductal carcinoma in situ (DCIS) is an often-diagnosed breast disease and a known, non-obligate, precursor to invasive breast carcinoma. In this review, we explore the clinical and pathological features of DCIS, fundamental elements of DCIS biology including gene expression and genetic events, the relationship of DCIS with recurrence and invasive breast cancer, and the interaction of DCIS with the microenvironment. We also survey how these various elements are being used to solve the clinical conundrum of how to optimally treat a disease that has potential to progress, and yet is also likely over-treated in a significant proportion of cases...
