RATIONALE AND OBJECTIVES: The addition of digital breast tomosynthesis (DBT) to digital screening mammography (DM) has been shown to decrease recall rates and improve cancer detection rates, but there is a lack of data regarding the impact of DBT on rates of short-term follow-up. We assessed possible changes in performance measures with the introduction of DBT at our facility. MATERIALS AND METHODS: In our observational study, databases were used to compare rates of recall, short-term follow-up, biopsy, and cancer detection between women undergoing DM without (n = 10,477) and women undergoing DM with (n = 2304) the addition of DBT...

BACKGROUND: Surgeons may receive a different diagnosis when a breast biopsy is interpreted by a second pathologist. The extent to which diagnostic agreement by the same pathologist varies at two time points is unknown. METHODS: Pathologists from eight U.S. states independently interpreted 60 breast specimens, one glass slide per case, on two occasions separated by ≥9 months. Reproducibility was assessed by comparing interpretations between the two time points; associations between reproducibility (intraobserver agreement rates); and characteristics of pathologists and cases were determined and also compared with interobserver agreement of baseline interpretations...

BACKGROUND: Reduction mammaplasty is one of the most common plastic surgery procedures. Preoperative imaging and histopathology protocols vary among countries and institutions. We aimed to analyze the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens. We also analyzed whether patients with abnormal histopathology differed from the study population in terms of demographics. PATIENTS AND METHODS: In total, 918 women who underwent reduction mammaplasty from January 2007 to December 2011 were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, pathology reports, and postoperative follow-up...

The exact roles of copy number alteration (CNA) in initiation, progression and immunotherapy of breast cancer and the genomic alterations behind progression from ductal carcinoma in situ (DCIS) to invasive carcinoma remain unknown. Quantitative multi-gene fluorescence in situ hybridization (QM-FISH) opens a possibility of large scale genomic analysis of specific deletions and amplifications with high-resolution at one cell level. We detected CNAs of 30 genes using QM-FISH and analyzed their association with clinicopathological parameters and patients' outcomes in 66 breast cancers with synchronous invasive carcinoma and DCIS...

Intraoperative radiotherapy (IORT) is a novel and increasingly utilized radiation technique in the treatment of breast carcinoma. There are few reports on the histologic changes seen in breast tissue from patients who have undergone IORT. We sought to evaluate the histologic changes observed in specimens received following IORT, as well as report an unusual case which prompted our study. A retrospective review of patients who received IORT and subsequently had breast tissue histologically evaluated at our institution was performed...

Diagnostic assays for human epidermal growth factor receptor 2 (HER2) expression have a high predictive value because patients with HER2-positive tumors could benefit from HER2-targeted therapy. The aim of the present study is to analyze the incidence of HER2 gene amplification in selected tumors with adverse features that scored 1+ by immunohistochemistry (IHC). For that purpose, 331 consecutive invasive breast cancers (IBCs) were tested by IHC for HER2 expression between January and December 2013, 102 of which (31%) scored 1+...

BACKGROUND: The efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of breast cancer are still questionable. It is estimated that the local recurrence rates following nipple-sparing mastectomy are very similar to breast-conserving surgery followed by radiotherapy. OBJECTIVES: To assess the efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of ductal carcinoma in situ and invasive breast cancer in women...

PURPOSE: The standard dose of postlumpectomy radiotherapy (RT) for ductal carcinoma in situ (DCIS) is 50 Gy in 25 fractions using conventional fractionation (CF). However, in invasive carcinoma, hypofractionation (HF) with 40 to 42.6 Gy in 15 to 16 fractions has largely become a standard of care. The purpose of this study was to review the management of postlumpectomy DCIS in terms of RT dose-fractionation and its impact on local recurrence (LR), in one of the largest Canadian academic centers...

BACKGROUND: Because of the increasing availability of screening mammography and spread of information about its benefits, the incidence of early breast cancer has been increasing in Japan. However, screening mammography can result in overdiagnoses or false positives, causing in some subjects undergoing unnecessary invasive procedures. The current mammography guidelines recommend further investigation of subjects with grouped amorphous calcifications; this recommendation may have resulted in overdiagnoses or false positives...

Ductal carcinoma in situ (DCIS) refers to neoplastic epithelial cells proliferating within the mammary ducts of the breast, which have not breached the basement membrane nor invaded surrounding tissues. Traditional thinking holds that DCIS represents an early step in a linear progression towards invasive ductal carcinoma (IDC). However, as only approximately half of DCIS cases progress to IDC, important questions around the key determinants of malignant progression need to be answered. Recent studies have revealed that molecular differences between DCIS and IDC cells are not found at the genomic level; instead, altered patterns of gene expression and post-translational regulation lead to distinct transcriptomic and proteomic profiles...

Ductal Carcinoma In Situ (DCIS) is the most frequently diagnosed early stage breast cancer. Only a subset of patients progress to invasive ductal carcinoma (IDC), and this presents a formidable clinical challenge for determining which patients to treat aggressively and which patients to monitor without therapeutic intervention. Understanding the molecular and genomic basis of invasion has been difficult to study in DCIS cancers due to several technical obstacles, including low tumour cellularity, lack of fresh-frozen tissues, and intratumour heterogeneity...

Lumpectomy with microscopically clear margins is a safe and effective approach for surgical management of breast carcinoma. Margins are positive for tumor in 18-50% of lumpectomies, as it is not possible to accurately determine the shape or microscopic borders of a tumor preoperatively or intraoperatively. We examined the 3D microanatomy and growth patterns of common breast carcinoma subtypes to provide guidance for lumpectomy surgery. Prospective consent was obtained for the use of excess tissue from patients undergoing lumpectomy or mastectomy for breast carcinoma...

PURPOSE: In certain ductal carcinoma in situ (DCIS) subpopulations, there is no consensus regarding whether to postoperatively irradiate; decisions are often made based on potential risk of cardiac toxicities. Given the utility of Surveillance, Epidemiology, and End Results (SEER) data for studying cardiac mortality in invasive disease, this is the first such study specific for DCIS patients, evaluating trends in cardiac mortality after left-sided radiotherapy (RT). METHODS: The SEER database was queried for patients with DCIS that received RT and had known unilaterality...
