PURPOSE: To assess the ability of chest CT to identify patients needing further evaluation of the breasts. METHODS: IRB approval was obtained with a waiver of consent. Women with chest CT and mammogram within 12months formed the cohort. A breast assessment and recommendation CT score (BARCS) analogous to mammographic BI-RADS was created and compared to the mammogram BI-RADS. RESULTS: BARCS and mammographic BI-RADS management recommendations were concordant for 77...

The inhibitor of DNA binding and cell differentiation (Id) proteins are dominant negative regulators of the helix-loop-helix transcription factor family and play a key role during development as well as in vascular disorders and cancer. In fact, impairing the Id-protein activity in cancer cells reduces cell growth and even chemoresistance. Recently, we have shown that a synthetic Id-protein ligand (1Y) consisting of a cyclic nonapeptide can reduce the viability of the two breast cancer cell lines MCF-7 and T47D and of the bladder cancer cells T24 to about 50% at concentrations ≥100μM...

BACKGROUND: The Norwegian Breast Cancer Screening Program (NBCSP) was implemented across the country in 2005 and has been criticised for potential 'overdiagnosis', i.e. a breast cancer diagnosis that otherwise would not have been detected or treated in a woman's lifetime. We aimed to estimate overdiagnosis in the NBCSP based on the Norwegian Women and Cancer (NOWAC) study using both questionnaire information and record linkage information from NBCSP. METHOD: For 124,978 women aged 49-79 years from the NOWAC study, information on screened women could be cross-validated from the NBCSP database...

Triphala (Trl) is an ayurvedic formulation used for treating disorders of the digestive, respiratory, and nervous systems. Its anticancer properties have also been documented. We studied effects of Trl on tubulin, a target protein for several anticancer drugs, and systematically elucidated a possible antiproliferative mechanism of action of Trl. Trl inhibited proliferation of HeLa (cervical adenocarcinoma), PANC-1 (pancreatic adenocarcinoma), and MDA-MB-231 (triple-negative breast carcinoma) cells in microgram quantities and strongly suppressed the clonogenicity of HeLa cells...

Despite the increasing evidence for the importance of immunity in breast cancer, the contradictory role of inflammation has not been thoroughly researched. In this study, we investigate the prognostic value of intratumoral inflammation as evaluated by cytokine mRNA levels. Intratumoral mRNA was measured for IL1β, IL6, IL8, IL10 and IL17A, using Taqman quantitative PCR. By the AUC criteria, none of the cytokines associated with metastasis outcome over the entire follow-up period. However, separation of the follow-up period has revealed a time-dependent and robust prognostic association of IL β...

Purpose One half of the Mexican population lacks comprehensive health care coverage. In 2003, a reform to the General Health Law was approved that led to the creation of the System of Social Protection in Health and made universal health coverage mandatory. The main innovation of this reform was Seguro Popular, which provided coverage for breast cancer. Here we report the outcomes of women with breast cancer treated at a cancer center in Mexico under Seguro Popular. Materials and Methods This was a retrospective cohort study that included all patients with breast cancer treated in the Instituto Nacional de Cancerología in Mexico City between January 2007 and December 2013 with Seguro Popular coverage...

Purpose Breast cancer, the most common cancer worldwide, is the leading cause of cancer mortality in Ghanaian women. Previous studies find Ghanaian women are diagnosed at a younger age and at more advanced stages (III and IV), and have tumors with characteristics similar to African American women. We sought to remedy gaps in knowledge about breast cancer survival in Ghana and its relation to demographic and biologic factors of the tumors at diagnosis to assist in cancer control and registration planning. Methods Individuals with a breast cancer diagnosis who sought care at Komfo Anokye Teaching Hospital from 2009 to 2014 were identified via medical records...

Purpose Malignancy-related hypercalcemia (MRH) is associated with a dismal prognosis. The widespread use of bisphosphonates (BPs), availability of more effective drugs in cancer treatment, and improvement in supportive care might have attenuated its impact. Patients and Methods To assess overall survival (OS) of patients with MRH in a contemporary setting, we conducted a retrospective analysis of 306 patients with solid cancer hospitalized for symptomatic hypercalcemia. A multivariable Cox proportional hazards regression model was performed to evaluate possible prognostic factors associated with MRH...

The molecular mechanisms involved in breast cancer progression and metastasis still remain unclear to date. It is a heterogeneous disease featuring several different phenotypes with consistently different biological characteristics. Neuroligins are neural cell adhesion molecules that have been implicated in heterotopic cell adhesion. In humans, alterations in neuroligin genes are implicated in autism and other cognitive diseases. Until recently, neuroligins have been shown to be abundantly expressed in blood vessels and also play a role implicated in the growth of glioma cells...

PURPOSE: Alcohol consumption is an established and important risk factor for breast cancer incidence in the general population. However, the relationship between alcohol and mortality among women with breast cancer is less clear. This study examines the effect of alcohol consumption on mortality in women affected with breast cancer at baseline from a high-risk family breast and ovarian cancer registry. METHODS: We studied 1116 women affected with breast cancer at baseline from the Metropolitan New York Registry...

With the increasing availability of multi-dimensional biological datasets for the same samples (i.e., gene expression, microRNAs, copy numbers, mutations, methylations), it has now become possible to systematically understand the regulatory mechanisms operating in a cancer cell. For this task, it is important to discover a set of co-expressed genes with functions, representing a so-called functional gene module, because co-expressed genes tend to be co-regulated by the same regulators, including transcription factors, microRNAs, and copy number aberrations...

Breast cancer heterogeneity is the main obstacle preventing the identification of patients with breast cancer with poor prognoses and treatment responses; however, such heterogeneity has not been well characterized. The purpose of this retrospective study was to reveal heterogeneous patterns in the apparent diffusion coefficient (ADC) signals in tumours and the surrounding stroma to predict molecular subtypes of breast cancer. A dataset of 126 patients with breast cancer, who underwent preoperative diffusion-weighted imaging (DWI) on a 3...

The impact of cold exposure while crated at a density characteristic of transport (83 kg/m2) was assessed in 12-wk-old turkey hens and 16-wk-old toms. Turkeys (72 toms, 72 hens) were randomly divided into 3 male and 3 female groups: 2 moderate 20°C groups with either 30% or 80% RH and a cold group exposed to -18°C, with uncontrolled, high RH. Groups of 8 birds (one replicate unit) were observed in a climate-controlled chamber for 8 h prior to slaughter. Core body temperature (CBT), live shrink, heterophil-lymphocyte ratio (HLR), and change in blood glucose levels were assessed; meat quality measures included thigh and breast muscle pH and L*, a*, and b* color values...

To determine the most suitable strategy in treating patients with invasive breast cancer from Northwest China. Lower recurrence score (RS) correlated with lower recurrence ratio. Patients having a medium-high 21-gene RS who received adjuvant therapy presented lower recurrence risk. Younger patients having RS results (⩾31) tended to accept adjuvant therapy more often, however, those having intermediate RS results were inclined to wait and did not receive chemotherapy. These results suggested that RS-based precision medicine will allow individualized diagnosis and treatment, resulting in better outcomes and preserved medical resources...

Cancer stem cells (CSCs) play a central role in the development of breast cancer. The canonical Wnt/β-catenin signal pathway is critical for maintaining CSCs characteristics. Diallyl trisulfide (DATS), a natural organosulfur compound from the garlic, exhibits effective antitumor properties. However, the role of DATS in regulating breast CSCs activity and the underlying molecular mechanisms remain obscure. In the present study, we reported that DATS efficiently inhibited the viability of breast CSCs as evidenced by reducing turmorspheres formation, decreasing the expression of breast CSCs markers (CD44, ALDH1A1, Nanog and Oct4), as well as inhibiting proliferation and inducing apoptosis...

Breast cancer is indisputably a heterogeneous disease, in which a formidable combination of definitely dis-regulated C-MYC and microRNA (miRNA) profiles along with other factors are responsible to generate a specific type of breast cancer. C-MYC as a master regulator of more than 20,000 genes can modify the expression of genes underlying to perform diverse conflicting functional frameworks. The functional spectra of miRNA in the new areas of the evolution of cell behaviors are identified. Here, we endeavor to summarize some recent advances of miRNA applications that can be recruited as combinatorial targeted therapy for patients with breast cancer...
