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...

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...

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...

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...

Background In breast magnetic resonance imaging (MRI), the diagnosis of ductal carcinoma in situ (DCIS) remains controversial; the most challenging cause of false-positive DCIS diagnosis is fibrocystic changes (FC). Purpose To search for typical and pathognomonic patterns of DCIS and FC using a standard clinical MRI protocol. Material and Methods Consecutive patients scheduled for breast MRI (standardized protocols @ 1.5T: dynamic-T1-GRE before/after Gd-DTPA [0.1 mmol/kg body weight (BW)]; T1-TSE), with subsequent pathological sampling, were investigated...

INTRODUCTION: Ductal carcinoma in situ (DCIS) is considered a heterogeneous lesion at the molecular level. However, there is a paucity of literature about the existence of molecular subtypes in DCIS which can predict their biological behavior at the preinvasive stage. MATERIALS AND METHODS: Precise prevalence of molecular subtypes of pure DCIS and DCIS component of infiltrating duct carcinoma (IDC) was evaluated using immunohistochemistry and correlated with known prognostic factors...

To investigate the clinicopathological characteristics and survival outcomes of microinvasive breast cancer, we conducted an observational study of female diagnosed with DCIS or DCIS with microinvasion (DCISM) from 1990 to 2012 using the Surveillance, Epidemiology, and End Results (SEER) database. There were 87695 DCIS and 8863 DCISM identified. In DCISM group, patients appeared to be younger and more black patients were identified in comparison with DCIS group. Furthermore, DCISM was associated with more aggressive tumor characteristics like higher rates of oestrogen receptor (ER) and progesterone receptor (PR) negativity, HER2 positivity, and lymph node metastasis...

BACKGROUND: Patients with a preoperative needle-biopsy diagnosis of ductal carcinoma in situ (DCIS) may have an indication for a sentinel lymph node biopsy if invasive carcinoma is found. We investigated how often a positive sentinel node and invasive carcinoma occurred in patients with a preoperative diagnosis of DCIS and whether this influenced the adjuvant regime. MATERIALS AND METHODS: From 2005 to 2014, the records of 240 patients with needle-biopsy diagnosis of DCIS were retrospectively reviewed for postoperative pathology outcomes of the sentinel node and breast, and decisions on adjuvant treatment...

: 175 Background: Many breast cancer patients overestimate their risk of distant recurrence after treatment. We explored risk perception in a large, diverse population of breast cancer patients with favorable prognosis and assessed associations between overestimation and quality of life (QoL). METHODS: As part of the iCanCare Study, we surveyed a weighted random sample of newly diagnosed patients with early-stage breast cancer treated in 2013-14, identified through the population-based SEER registries of Los Angeles & Georgia about 3 months after surgical treatment (N = 2632, RR = 70%)...

OBJECTIVE: The follow-up of breast lesions with imaging-concordant benign histopathology results on MRI-guided vacuum-assisted biopsy (VAB) is not currently standardized. We determined the false omission rate of breast MRI-guided VAB with benign histopathology (negative results) to assess whether breast MRI follow-up is needed. MATERIALS AND METHODS: The medical records of patients who underwent 9-gauge breast MRI-guided VAB during 2007-2012 were reviewed retrospectively...

Although ductal carcinoma in situ(DCIS)is generally cured by surgical resection, it has been suggested that resection is over-treatment for some patients with DCIS. The aim of this study was to reconsider operative indications for patients with DCIS by examining clinicopathological features of 23 patients who underwent surgical resection for DCIS in our institute over a single year. Postoperative histological examination revealed that there were Luminal and HER2-positive subtypes, but no triple negative cancers...

BACKGROUND: Most women with ductal carcinoma in situ (DCIS) will receive breast-conserving surgery (BCS) and radiation (RT). RT can be omitted for women at low risk of local recurrence (LR). The Oncotype DX DCIS score (DS) predicts LR risk after BCS alone. This study assesses the impact of RT and DS on LR risk. METHODS: Population-based cohort analysis of individuals with DCIS treated by BCS ± RT from 1994-2003. Treatment and outcomes were determined by linkage and chart review...
