OBJECTIVE: The purposes of this review are to discuss the motivation for supplemental screening, to address molecular breast imaging (MBI) radiation dose concerns, and to provide an updated guide to current MBI technology, clinical protocols, and screening performance. Future directions of MBI are also discussed. CONCLUSION: MBI offers detection of mammographically occult cancers in women with dense breasts. Although MBI has been under investigation for nearly 15 years, it has yet to gain widespread adoption in breast screening...

OBJECTIVE: The purpose of this article is to delineate the potential techniques for percutaneous ablation of breast cancer, discuss the advantages and disadvantages of each technique, and provide results from recent studies on these technologies. The techniques discussed are cryotherapy, laser irradiation, microwave irradiation, radiofrequency ablation, high-intensity focused ultrasound ablation, and irreversible electroporation. CONCLUSION: Although percutaneous ablation techniques have some promising potential for less-invasive treatment of breast cancer, larger multicenter trials are needed to confirm their efficacy, especially in comparison with the reference standard of lumpectomy...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

Small membranous secretions from tumor cells, termed exosomes, contribute significantly to intercellular communication and subsequent reprogramming of the tumor microenvironment. Here we use optical imaging to determine that exogenously administered fluorescently-labeled exosomes derived from highly metastatic murine breast cancer cells, distributed predominantly to the lung of syngeneic mice, a frequent site of breast cancer metastasis. At the sites of accumulation, exosomes were taken up by CD45+ bone marrow-derived cells...

This work presents a fluid dynamic study of milk flow in lactating human breast. The motivation for this study is in part to improve the fundamental understanding of transport processes in an important but insufficiently studied human organ, and in part to produce a new methodology for the understanding of the pathologies of lactation, which can have a huge impact on the health and well-being of a significant proportion of the population. This collaborative effort among lactation specialists and fluid dynamic engineers starts with a careful, statistically representative measurement of infant suckling patterns...

An accurate diagnosis of metastases to the ovary is essential for adequate patient management. The aim of this retrospective study was to characterize clinicopathological features of metastatic malignancies that presented as an ovarian mass and compare them with their corresponding primary tumors. We reviewed clinical files and histological material of 120 patients with metastases to the ovary, diagnosed in our center between 2000 and 2014. Metastases were diagnosed before (18 %), synchronously (33 %), or after (49 %) the primary tumor was identified; 25 % were single, 40 % were unilateral; 47 % were ≥13 cm...

Several techniques for measuring breast volume (BV) are based on examining the breast on magnetic resonance imaging. However, when techniques designed to measure total BV are used to quantify BV changes, for example, after fat grafting, a systematic error is introduced because BV changes lead to contour alterations of the breast. The volume of the altered breast includes not only the injected volume but also tissue previously surrounding the breast. Therefore, the quantitative difference in BV before and after augmentation will differ from the injected volume...

BACKGROUND: Different techniques have been used for the guidance of nonpalpable breast cancer (NBC), but none of them has yet achieved perfect results. The aim of this study was to evaluate the feasibility of indocyanine green (ICG) fluorescence-guided nonpalpable breast cancer lesion excision (IFNLE), to introduce an alternative technique. METHODS: The data about 56 patients with preoperatively diagnosed NBCs operated with the help of intraoperative IFNLE between November of 2010 and September of 2014 were retrospectively analyzed...

BACKGROUND: Membrane Type-1 Matrix Metalloproteinase (MT1-MMP) is a multifunctional protease implicated in metastatic progression ostensibly due to its ability to degrade extracellular matrix (ECM) components and allow migration of cells through the basement membrane. Despite in vitro studies demonstrating this principle, this knowledge has not translated into the use of MMP inhibitors (MMPi) as effective cancer therapeutics, or been corroborated by evidence of in vivo ECM degradation mediated by MT1-MMP, suggesting that our understanding of the role of MT1-MMP in cancer progression is incomplete...

BACKGROUND: To evaluate the accuracy of sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) in breast cancer patients with axillary lymph node (ALN) metastasis. METHODS: A total of 122 patients with operable breast cancer were enrolled in this single-center retrospective study. Eighty patients were clinically diagnosed with a positive axillary lymph node (ALN) via imaging or physical examination (including 66 patients with biopsy-proven metastasis)...

The sentinel lymph node (SLN) is defined as the first regional lymph node to receive lymphatic drainage from a malignant tumor. Therefore, this node is a "sentinel" for second metastatic lymph node stations and for labeling regional tumor spread. For SLN detection, many surgeons preferred a combination of a preoperative injection of radiolabeled colloid and the intraoperative injection of blue dye. Under this combination protocol, nodes are considered to be "sentinel nodes" if they are radioactive and blue...

BACKGROUND: Human epidermal growth factor receptor 2-positive (HER2+) breast cancer has two distinct subtypes according to hormone receptor (HR) status. Survival, pattern of recurrence, and treatment response differ between HR-/HER2+ and HR+/HER2+ cancers. PURPOSE: To investigate imaging and clinicopathologic features of HER2+ cancers and their correlation with HR expression. MATERIAL AND METHODS: Between 2011 and 2013, 252 consecutive patients with 252 surgically confirmed HER2+ cancers (125 HR- and 127 HR+) were included...

INTRODUCTION: The use of texture indices (TI) to characterize tumor heterogeneity from Positron Emission Tomography (PET) images is increasingly investigated in retrospective studies. Yet, the interpretation of PET-derived TI values has not been thoroughly reported. Furthermore, the calculation of TI lacks a standardized methodology, making it difficult to compare published results. To allow for TI value interpretation, we investigated the changes in value of six TI computed from simulated and real patient data...

AIMS: Recently, microtubule-binding proteins (MBPs) have been implicated in modulation of paclitaxel sensitivity in many cancers, highlighting their potential as biomarkers predictive of treatment outcomes and as therapeutic targets that can be pharmacologically manipulated. This study is aimed to determine the impact of the MBP hematopoietic PBX-interaction protein (HPIP) on breast cancer cell sensitivity to paclitaxel. RESULTS: In this study, we show that breast cancer cells (MCF-7 and MDA-MB-231) overexpressing HPIP were more sensitive to paclitaxel treatment as evaluated by MTT assay, exhibiting a significant reduction in IC50 of paclitaxel compared with the control...

Third Harmonic Generation (THG) microscopy as a non-invasive, label free imaging methodology, allows linkage of lipid profiles with various breast cancer cells. The collected THG signal arise mostly from the lipid droplets and the membrane lipid bilayer. Quantification of THG signal can accurately distinguish HER2-positive cells. Further analysis using Fourier transform infrared (FTIR) spectra reveals cancer-specific profiles, correlating lipid raft-corresponding spectra to THG signal, associating thus THG to chemical information...

Solitary fibrous tumor (SFT) is an uncommon neoplasm of mesenchymal origin, which can be benign or malignant. Most SFTs develop from the pleura, but they can also be found in other sites. There are only few reports of SFT occurring in the breast. We herein report such a rare case. Sonography demonstrated an ovoid lesion mimicking a fibroadenoma, whereas color Doppler imaging showed marked internal vascularity. A brief literature review on imaging features of SFTs is added. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound, 2016...

Galactocele is a rare breast condition in infants. Here, we report a 16-month-old boy who developed progressive left breast enlargement. Ultrasonography and magnetic resonance imaging revealed a 4 cm cystic lesion at left breast. Hormonal assay showed transient hyperprolactinaemia with no known cause identified. Subsequently, galactocele was confirmed on histopathological examination after complete surgical excision. No recurrence was observed on regular follow-up.
