Automated Breast Ultrasound (ABUS) is highly effective as breast cancer screening adjunct technology. Automation can greatly enhance the efficiency of the clinician sifting through the quantum of data in ABUS volumes to spot lesions. We have implemented a fully automatic generic algorithm pipeline for detection and characterization of lesions on such 3D volumes. We compare a wide range of features for region description on their effectiveness at the dual goals of lesion detection and characterization. On multiple feature images, we compute region descriptors at lesion candidate locations obviating the need for explicit lesion segmentation...

PURPOSE: Tumor genomic testing has become widely available in many clinical settings. However, we do not yet understand how to best harness the information yielded from this testing. We retrospectively investigated the clinical courses of 24 patients who underwent tumor genomic testing to determine whether targeted therapy is associated with improved progression free survival (PFS) compared to standard therapy. METHODS: The patient population comprised metastatic breast cancer patients who underwent tumor genomic testing (testing biopsy specimens of primary or metastatic lesions for 50 commonly mutated genes) at our institution between September 1, 2010 and June 1, 2015...

Hydatidosis is caused by Echinococcus granulosus. Humans may be infected incidentally as intermediate host by the accidental consumption of soil, water, or food contaminated by fecal matter of an infected animal. Hydatidosis is one of the most symptomatic parasitic infections in various livestock - raising countries. Lung is the second most commonly affected organ following the liver. The symptoms depend on the size and site of the lesion. It can present as an asymptomatic pulmonary lesion to hemoptysis, chest pain, coughing anaphylaxis, and shock...

We have previously reported hepcidin and ferritin increases in the plasma of breast cancer patients, but not in patients with benign breast disease. We hypothesized that these differences in systemic iron homeostasis may reflect alterations in different iron-related proteins also play a key biochemical and regulatory role in breast cancer. Thus, here we explored the expression of a bundle of molecules involved in both iron homeostasis and tumorigenesis in tissue samples. Enzyme-linked immunosorbent assay (ELISA) or reverse-phase protein array (RPPA), were used to measure the expression of 20 proteins linked to iron processes in 24 non-cancerous, and 56 cancerous, breast tumors...

Breast cancer is an important global health problem, and the most common type of cancer among women. Late diagnosis significantly decreases the survival rate of the patient; however, using mammography for early detection has been demonstrated to be a very important tool increasing the survival rate. The purpose of this paper is to obtain a multivariate model to classify benign and malignant tumor lesions using a computer-assisted diagnosis with a genetic algorithm in training and test datasets from mammography image features...

INTRODUCTION: Breast radial scar (RS) management remains controversial. The need for surgical excision is supported by the concern of an associated high-grade lesion missed in the biopsy. The aim of this study was to assess histologic upgrade rate after a percutaneous biopsy, to determine if vacuum assisted biopsy prevents the need for subsequent RS surgical resection and to evaluate the upgrade risk factors. PATIENTS AND METHODS: This was a uni-institutional retrospective study of consecutive patients with RS histologically diagnosed from January 2010 to December 2015...

CLINICAL ISSUE: In the daily clinical routine characterization of focal lesions using native B‑mode classical ultrasound and color Doppler can be difficult or insufficient; therefore, additional diagnostic information must be taken into consideration. STANDARD RADIOLOGICAL METHODS: Standard radiological methods in the daily clinical routine include native B‑mode ultrasound and color Doppler ultrasound. METHODICAL INNOVATIONS: Using sonoelastography it is possible to evaluate and characterize tissue properties and focal lesions regarding their stiffness to acquire additional information on a noninvasive basis...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

Bone metastasis affects more than 70% of patients with advanced breast cancer. However, the molecular mechanisms underlying this process remain unclear. Based on the analysis of clinical datasets, and in vitro and in vivo experiments, we report that the ZNF217 oncogene is a crucial mediator and indicator of bone metastasis. Patients with high ZNF217 mRNA expression levels in primary breast tumours had a higher risk of developing bone metastases. MDA-MB-231 breast cancer cells stably transfected with ZNF217 (MDA-MB-231-ZNF217) displayed the dysregulated expression of a set of genes with bone homing and metastasis characteristics, which overlapped with two previously described "osteolytic bone metastasis" gene signatures, while also highlighting the bone morphogenetic protein (BMP) pathway...
