Aim of the study was to provide information about the prevalence of cancer related fatigue and the association between treatment-related factors and fatigue in cancer patients during the rehabilitation care. In a multicenter study 693 cancer patients (27% breast cancer, 17% prostate cancer etc.) completed the Multidimensional Fatigue Inventory (MFI-20) and sociodemographic and treatment information was noted. 51% of the patients suffer from fatigue (n=356). Fatigue prevalence differed according to tumour localization (p≤0...

Memristors have been considered as a leading candidate for a number of critical applications ranging from non-volatile memory to non-Von Neumann computing systems. Feature extraction, which aims to transform input data from a high dimensional space to a space with fewer dimensions, is an important technique widely used in machine learning and pattern recognition applications. Here, we experimentally demonstrate that memristor arrays can be used to perform principal component analysis (PCA), one of the most commonly-used feature extraction techniques, through online, unsupervised learning...

Epithelial-mesenchymal transition (EMT) is an evolutionarily conserved cellular program, which is a prerequisite for the metastatic cascade in carcinoma progression. Here, we evaluate the EMT process using the sea urchin Paracentrotus lividus embryo. In sea urchin embryos, the earliest EMT event is related to the acquisition of a mesenchymal phenotype by the spiculogenetic primary mesenchyme cells (PMCs) and their migration into the blastocoel. We investigated the effect of inhibiting the epidermal growth factor (EGF) signaling pathway on this process, and we observed that mesenchyme cell differentiation was blocked...

GT198, located 470 kb downstream of BRCA1, encodes for the nuclear PSMC3-interacting protein, which functions as co-activator of steroid hormone-mediated gene expression, and is involved in RAD51 and DMC1-mediated homologous recombination during DNA repair of double-strand breaks. Recently, germline variants in GT198 have been identified in hereditary breast and ovarian cancer (HBOC) patients, mainly in cases with early-onset. We screened a cohort of 166 BRCA1/2 mutation-negative HBOC patients, of which 56 developed early-onset breast cancer before the age of 36 years, for GT198 variants...

Pancreatic ductal adenocarcinoma (PDA) accounts for 95% of all pancreatic cancers. About 230,000 PDA cases are diagnosed worldwide each year. PDA has the lowest five-year survival rate as compared to others cancers. PDA in Poland is the fifth leading cause of death after lung, stomach, colon and breast cancer. In our paper we have analysed the newest epidemiological research, some of it controversial, to establish the best practical solution for pancreatic cancer prevention in the healthy population as well as treatment for patients already diagnosed with pancreatic cancer...

Long noncoding RNA (lncRNA) has been proven to be involved in many biological processes in ovarian cancer (OC). However, the mechanism still remains unknown. In this study, we screened significantly downregulated NBAT-1, which has been proven to play a significant role in breast cancer, clear cell renal cell carcinoma, and neuroblastoma, but not in OC, in two independent datasets with relatively more samples (GSE18520 and GSE38666) from Gene Expression Omnibus. We found that lncRNA NBAT-1 was obviously downregulated in OC tissue compared to normal ovarian tissue (P<0...

PURPOSE: Breast cancer is the most common cancer in females and the leading cause of death worldwide. The effects of statins on breast cancer prognosis have long been controversial; thus, it is important to investigate the relationship between statin type, exposure time, and breast cancer prognosis. This study sought to explore the effect of statins, as well as the different effects of statin solubility and variable follow-up times, on breast cancer prognosis. METHODS: We searched the MEDLINE (via PubMed), EMBASE (via OvidSP), Cochrane Library, and ISI Web of Knowledge databases using combinations of the terms "breast neoplasms[MeSH]," "statins" or "lipid-lowering drug," "prognosis" or "survival," or "mortality" or "outcome" with no limit on the publication date...

PURPOSE: Parallel to increasing survival of breast cancer (BC) patients, a need has arisen to characterize the follow-up required to improve and maintain their health. Our study aimed to assess changes in lifestyle habits over time among the study population, compare compliance rates of selected primary and secondary prevention practices between long-term BC survivors and an age-matched comparison group, and identify factors associated with compliance to these practices. METHODS: The study population comprised 250 Israeli BC survivors, diagnosed with BC between 1999 and 2003, without evidence of disease after 8-12 years, and 250 women with no cancer history, individually matched to survivors by age and area of residence...

The majority of breast cancer models for drug discovery are based on orthotopic or subcutaneous tumours. Therapeutic responses of metastases, especially microscopic metastases, are likely to differ from these tumours due to distinct cancer-microenvironment crosstalk in distant organs. Here, to recapitulate such differences, we established an ex vivo bone metastasis model, termed bone-in-culture array or BICA, by fragmenting mouse bones preloaded with breast cancer cells via intra-iliac artery injection. Cancer cells in BICA maintain features of in vivo bone micrometastases regarding the microenvironmental niche, gene expression profile, metastatic growth kinetics and therapeutic responses...

As noted by Warburg, many cancer cells depend on the consumption of glucose. We performed a genetic screen to identify factors responsible for glucose addiction and recovered the two subunits of the xCT antiporter (system xc(-)), which plays an antioxidant role by exporting glutamate for cystine. Disruption of the xCT antiporter greatly improves cell viability after glucose withdrawal, because conservation of glutamate enables cells to maintain mitochondrial respiration. In some breast cancer cells, xCT antiporter expression is upregulated through the antioxidant transcription factor Nrf2 and contributes to their requirement for glucose as a carbon source...

The European Society of Breast Cancer Specialists has created quality indicators for breast units to establish the minimum standards of care for patients. In Italy, each region differs, indeed, in terms of health care and services warranted to patients suffering from breast cancer. Since Sicilian Regional Administration today is still disregarding implementation of the provisions contained in the proposal of the Ministry of Health entitled "Guidelines on Organizational and Health Care Methods of Breast Centers Network" in November 2015 the Sicilian Regional Group of the Italian Society of Radiology (SIRM) decided to carry out a survey to see the position of the Sicilian Healthcare System and define the gap to bridge over...

Brain metastasis from breast cancer generally represents a catastrophic event yet demonstrates substantial biological heterogeneity. There have been limited studies solely focusing on the prognosis of patients with such metastasis. In this study, we carried out a comprehensive analysis in 108 consecutive patients with breast cancer brain metastases between 1997 and 2012 to further define clinicopathologic factors associated with early onset of brain metastasis and survival outcomes after development of them...

Targeted therapy is unavailable for treating patients with triple-negative breast cancer (TNBC), which accounts for approximately 15% of all breast cancers. Overexpression of epidermal growth factor receptor (EGFR) is observed in approximately 30-60% of TNBCs. Therefore, developing novel strategies for inhibiting EGFR signaling is required. In the present study, a natural compound library was screened to identify molecules that target TNBCs that overexpress EGFR. Picrasidine G (PG), a naturally occurring dimeric alkaloid produced by Picrasma quassioides, decreased the viability of the MDA-MB 468 cell line (TNBC(EGFR+)) compared with other breast cancer cell lines...
