Objectives: Fibromatosis of the breast is an uncommon neoplasm with potential for local recurrence. Treatment has traditionally been surgical excision with current trends toward conservative management. Given the option of observation after diagnosis by core needle biopsy (CNB), we sought to evaluate the accuracy of CNB for diagnosing fibromatosis. Methods: We identified a total of 31 cases in which fibromatosis had been diagnosed or included in the differential diagnosis on a CNB, an excision, or both...

Tumor necrosis factor alpha (TNF-α) has both positive and negative roles in human disease. In certain cancers, TNF-α is infused locally to promote tumor regression, but dose-limiting inflammatory effects limit broader utility. In autoimmune disease, anti-TNF-α antibodies control inflammation in most patients, but these benefits are offset during chronic treatment. TAK1 acts as a key mediator between survival and cell death in TNF-α-mediated signaling. Here, we describe Takinib, a potent and selective TAK1 inhibitor that induces apoptosis following TNF-α stimulation in cell models of rheumatoid arthritis and metastatic breast cancer...

Ribosomopathies comprise a heterogeneous group of hematologic and developmental disorders, often characterized by bone marrow failure, skeletal and other developmental abnormalities and cancer predisposition. They are associated with mutations and/or haplo-insufficiencies of ribosomal proteins (RPs) and inefficient ribosomal RNA (rRNA) processing. The resulting ribosomal stress induces the canonical p19ARF/Mdm2/p53 tumor suppressor pathway leading to proliferative arrest and/or apoptosis. It has been proposed that this pathway is then inactivated during subsequent neoplastic evolution...

Purpose In the United States, 3.8 million women have a history of breast (BC) or ovarian cancer (OC). Up to 15% of cases are attributable to heritable mutations, which, if identified, provide critical knowledge for treatment and preventive care. It is unknown how many patients who are at high risk for these mutations have not been tested and how rates vary by risk criteria. Methods We used pooled cross-sectional data from three Cancer Control Modules (2005, 2010, 2015) of the National Health Interview Survey, a national in-person household interview survey...

Celebrities can have a powerful influence on people's health-related attitudes and behaviors, often by publicly disclosing their own personal health decisions. In May 2013, Angelina Jolie, an internationally recognized actress, director, and author, wrote an op-ed for the New York Times disclosing her decision to undergo a prophylactic double mastectomy to reduce her risk of breast cancer after learning that she carried the BRCA1 gene mutation. This cross-sectional study examined whether exposure to Angelina Jolie and her mastectomy disclosure and parasocial involvement (PSI) with Angelina Jolie were related to female college students' perceived risk of breast cancer and breast cancer screening intentions...

Primary and secondary bone cancers are major causes of pathological bone fractures and their treatment through implant fixation and conventional chemotherapy has many limitations. These implants may suffer from poor osseointegration and their rejection is causing repeated surgery, patient's suffering and extensive expenses. On the other hand, there are severe systemic adverse effects of toxic chemotherapeutics administrated using conventional drug delivery. In this paper to address these two problems we present new type of localized drug-releasing titanium implants with enhanced implants' bio-integration and drug release capabilities that could provide high concentration of toxic anticancer drugs locally to treat bone cancers...

Asparagine endopeptidase (AEP), also called legumain, is highly expressed in various solid tumors, promoting cancer cell invasion, migration, and metastasis. It has been proposed to be a prognostic marker and therapeutic target for cancer treatment. However, an effective nonpeptide, small-molecule inhibitor against this protease has not yet been identified. Here we show that a family of xanthine derivatives selectively inhibit AEP and suppress matrix metalloproteinase (MMP) cleavage, leading to the inhibition of cancer metastasis...

This paper explores the adhesion of biosynthesized gold nanoparticles (AuNPs) and gold (Au) nanoparticle/prodigiosin (PG) drug nanoparticles to breast cancer cells (MDA-MB-231 cells). The AuNPs were synthesized in a record time (less than 30 s) from Nauclea latifolia leaf extracts, while the PG was produced via bacterial synthesis with Serratia marcescens sp. The size distributions and shapes of the resulting AuNPs were characterized using transmission electron microscopy (TEM), while the resulting hydrodynamic diameters and polydispersity indices were studied using dynamic light scattering (DLS)...

BACKGROUND: Mammography detects calcium deposits sensitively, but the specificity for differentiating malignancy from benign calcifications is low. Thus, we investigated whether adjunctive breast-specific gamma imaging (BSGI) has incremental value for detecting cancer in women with suspicious calcifications detected by mammography, and compared BSGI with adjunctive ultrasonography (US). METHODS: The medical records of women without a personal history of breast cancer who underwent mammography for breast evaluation from 2009 to 2014 were reviewed retrospectively...

Circulating tumor cells (CTCs) are a rare population of cells found in the peripheral blood of patients with many types of cancer such as breast, prostate, colon, and lung cancers. Higher numbers of these cells in blood are associated with a poorer prognosis of patients. Genomic profiling of CTCs would help characterize markers specific for the identification of these cells in blood, and also define genomic alterations that give these cells a metastatic advantage over other cells in the primary tumor. Here, we describe an immunomagnetic method to enrich CTCs from the blood of patients with breast cancer, followed by single-cell laser capture microdissection to isolate single CTCs...

In order to realize a combination of chemotherapy and selective drug release into tumor cells, novel pH-sensitive prodrugnanoparticles were designed and prepared via the self-assembly of a synthetic amphiphilic macromolecular prodrug for the selective co-delivery of doxorubicin (Dox) and curcumin (Cur). Dox was covalently conjugated to the oxidized sodium alginate through a Schiff base reaction to produce an amphiphilic macromolecular prodrug, and the prodrug was subsequently self-assembled into nanoparticles (Dox-NPs) in an aqueous solution, which were responsive to the acidic environment in tumor cells...

INTRODUCTION: Pathological fractures due to secondaries in the bone are common with carcinoma of lung, breast, prostate, and in multiple myeloma. Multiple pathological fractures after a trivial fall, indicating metastases warrants detailed investigations for the search of primary. Skeletal secondaries should be strongly suspected in addition to obvious diagnosis of multiple myeloma in such cases. CASE REPORT: We report a case of pathological fractures at multiple sites: The vertebral column, proximal shaft of femur, and contralateral fracture neck of femur...

Global gene expression profiling identifies predictive and prognostic biomarkers and rationalizes breast cancer subtype-targeted treatment. The Anthracyclin/Taxol and survival pathway specific small molecular inhibitors, constitute current treatment options. These options are associated with acquired tumor resistance and emergence of drug-resistant cancer stem cells. Dietary supplements and constitutive bioactive phytochemicals with relatively low systemic toxicity may provide testable alternatives for current therapy...
