OBJECTIVE: Meningeal carcinomatosis (MC) is a rare complication in breast cancer patients. It is defined as a diffuse or multifocal leptomeningeal metastasis. STUDY DESIGN: From our institution database, we retrospectively studied 19 patients diagnosed with MC in the cerebrospinal fluid (CSF) in 1997-2015, in order to evaluate tumor prognostic markers, histologic subtypes, and clinical outcome. RESULTS: All patients were female, with a mean age of 53 years (range 36-75 years)...

Neuroendocrine tumors of the breast are very rare accounting for less than 0.1% of all breast cancers and less than 1% of all neuroendocrine tumors. Focal neuroendocrine differentiation can be found in different histologic types of breast carcinoma including in situ and invasive ductal or invasive lobular. However, primary neuroendocrine carcinoma of the breast requires the expression of neuroendocrine markers in more than 50% of the cell population, the presence of ductal carcinoma in situ, and the absence of clinical evidence of concurrent primary neuroendocrine carcinoma of any other organ...

BACKGROUND: Women diagnosed with lobular carcinoma in situ (LCIS) have a 3-fold to 10-fold increased risk of developing invasive breast cancer. The objective of this study was to evaluate the life expectancy (LE) and differences in survival offered by active surveillance, risk-reducing chemoprevention, and bilateral prophylactic mastectomy among women with LCIS. METHODS: A Markov simulation model was constructed to determine average LE and quality-adjusted LE (QALE) gains for hypothetical cohorts of women diagnosed with LCIS at various ages under alternative risk-reduction strategies...

BACKGROUND: The recent investigations have rendered microRNAs (miRs) as a novel biomarker in cancer research. In fact, alteration in miR expression may be associated with tumor suppression, tumorigenesis, metastasis, and poor prognosis in human breast cancer (BC). OBJECTIVES: The aim of this clinical experimental study was to measure the miR-328 expression level in breast cancer tissues, at first. Then, we tried to find out any possible correlation between miR-328 and prognostic and predictive biomarkers in BC...

BACKGROUND: Up to 90% of patients undergoing breast cancer surgery suffer from seroma formation, which can cause discomfort and various complications after mastectomy. This retrospective observational cohort study aimed to elucidate whether flap fixation with fibrin sealant (ARTISS) tissue glue reduces seroma formation and seroma aspiration after mastectomy when compared with flap fixation using Vicryl sutures and when compared with a conventional wound closure technique. METHODS: All patients undergoing mastectomy due to invasive breast cancer or ductal carcinoma in situ were eligible for inclusion...

OBJECTIVE: We hypothesize that radiologists' estimated percentage likelihood assessments for the presence of ductal carcinoma in situ (DCIS) and invasive cancer may predict histologic outcomes. MATERIALS AND METHODS: Two hundred fifty cases categorized as BI-RADS category 4 or 5 at four University of California Medical Centers were retrospectively reviewed by 10 academic radiologists with a range of 1-39 years in practice. Readers assigned BI-RADS category (1, 2, 3, 4a, 4b, 4c, or 5), estimated percentage likelihood of DCIS or invasive cancer (0-100%), and confidence rating (1 = low, 5 = high) after reviewing screening and diagnostic mammograms and ultrasound images...

Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT) done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made...

EDITORIAL
Alan Hollingsworth
Overdiagnosis in breast cancer has been a focus of increasing concern with wide ranges of calculations made indirectly through the study of prospective randomized trials and analyses of large registries. While most admit that some degree of overdiagnosis is inherent with ductal carcinoma in situ (DCIS), the rate of overdiagnosis with invasive disease is highly controversial. Although it is generally accepted that overdiagnosis is calculated through indirect means and deductive reasoning, this is not entirely the case...

INTRODUCTION: Modern full-field digital mammography (FFDM) appears to have increased the detection of breast microcalcification. This retrospective study aimed to assess whether this is associated with over-investigation and possible over-diagnosis of breast pathology of lesser significance. METHODS: Three 2-year periods were studied, in which different mammographic technologies were used exclusively viz., classical screen-film mammography (SFM) in 2003-04, computed radiography (CR) in 2009-10 and FFDM in 2012-13...

BACKGROUND: Many Western countries have long-established population-based mammography screening programs. Prior to implementing these programs, decision-analytic modeling was widely used to inform decisions. OBJECTIVE: The aim of this study was to perform a systematic review of cost-effectiveness models in breast cancer screening in the general population to analyze their structural and methodological approaches. METHODS: A systematic literature search for health economic models was performed in the electronic databases MEDLINE (Ovid), EMBASE, CRD Databases, Cochrane Library, and EconLit in August 2011 with updates in June 2013, April 2015, and November 2016...

The aim of this study was to find the differences and relationships between normal, atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS), and invasive ductal carcinoma (IDC) lesions of the breast based on biochemical characteristics determined by Raman spectroscopy (RS). After collecting 39 frozen sections from patients who underwent surgical resection or mammotome biopsy, nine normal tissues, seven ADH, eight DCIS, and 15 IDC lesions were detected using confocal RS. We then used leave-one-out cross-validation (LOOCV) and radial basis function (RBF) to build a support vector machine (SVM) diagnosis model...

BACKGROUND: The molecular signature of ductal carcinoma in situ (DCIS) in the breast is not well understood. Erb-b2 receptor tyrosine kinase 2 (ERBB2 [formerly known as HER2/neu]) positivity in DCIS is predictive of coexistent early invasive breast carcinoma. The aim of this study is to identify the gene-expression signature profiles of estrogen receptor (ER)/progesterone receptor (PR)-positive, ERBB2, and triple-negative subtypes of DCIS. METHODS: Based on ER, PR, and ERBB2 status, a total of 18 high nuclear grade DCIS cases with no evidence of invasive breast carcinoma were selected along with 6 non-neoplastic controls...
