Cancer health disparities may exist based on the facility type. We aimed to determine the association between the academic status of centers and outcomes of patients with acute myeloid leukemia (AML). Using the National Cancer Data Base, we compared one-month mortality and longer-term overall survival (OS) of 60,738 patients with AML, who received first course treatment between 2003-2011 at academic or non-academic centers (community cancer program, comprehensive community cancer program, and others). Multivariate analysis was done using logistic regression for one-month mortality and Cox regression with backward elimination approach for OS...

Because of the rarity of hepatic vein tumor thrombus (HVTT), compared with portal vein tumor thrombus (PVTT), in patients with hepatocellular carcinoma (HCC), little is known about this disease entity. The aim of this study was to evaluate the prognosis of each treatment modality for HVTT through an analysis of data collected in a Japanese nationwide survey. We analyzed data for 1,021 Child-Pugh A HCC patients with HVTT without inferior vena cava invasion registered between 2000 and 2007. Of these patients, 540 patients who underwent liver resection (LR) and 481 patients who received other treatments were compared...

BACKGROUND: Distress in cancer patients leads to poorer quality of life (QOL) and negatively impacts survival. For efficient management of a patient's disease course, the interrelationships among distress, depression, insomnia, and QOL must be understood. This study aimed to investigate whether depression and insomnia mediate the relationship between distress and QOL in cancer patients. METHODS: Cancer patients referred to a specialized psycho-oncology clinic (n=208) participated in this study...

Purpose: Prominin-1 (Prom1) is a transmembrane glycoprotein, which is expressed in stem cell lineages, and has recently been implicated in cancer stem cell survival. Mutations in the Prom1 gene have been shown to disrupt photoreceptor disk morphogenesis and cause an autosomal dominant form of Stargardt-like macular dystrophy (STGD4). Despite the apparent structural role of Prom1 in photoreceptors, its role in other cells of the retina is unknown. The purpose of this study is to investigate the role of Prom1 in the highly metabolically active cells of the retinal pigment epithelium (RPE)...

Ketogenic diets are low in carbohydrates and high in fat, which forces cells to rely more heavily upon mitochondrial oxidation of fatty acids for energy. Relative to normal cells, cancer cells are believed to exist under a condition of chronic mitochondrial oxidative stress that is compensated for by increases in glucose metabolism to generate reducing equivalents. In this study we tested the hypothesis that a ketogenic diet concurrent with radiation and chemotherapy would be clinically tolerable in locally advanced non-small cell lung cancer (NSCLC) and pancreatic cancer and could potentially exploit cancer cell oxidative metabolism to improve therapeutic outcomes...

While radiotherapy continues to be a major cancer treatment option, its dose-limiting side effects, such as pulmonary fibrosis, severely impair the quality of life in these patients. In this study, we evaluated the radioprotective effects of metformin, a commonly used biguanide antidiabetic medication, in a murine model of pulmonary damage. Sprague Dawley(®) rats received whole lung 20 Gy irradiation with or without metformin treatment. Computed tomography (CT) was performed and Hounsfield units (HU) were determined during the observation period...

MicroRNAs (miRNAs) help orchestrate cellular growth and survival through post-transcriptional mechanisms. The dysregulation of miRNA biogenesis can lead to cellular growth defects, chemotherapeutic resistance and plays a direct role in the development of many chronic diseases. Among these RNAs, miR-21 is consistently overexpressed in most human cancers leading to the down regulation of key tumor suppressing and pro-apoptotic factors; suggesting that inhibition of miR-21 biogenesis could reverse these negative effects...

The generation of tumour-specific T cells is critically important for cancer immunotherapy. A major challenge in achieving a robust T-cell response is the spatiotemporal orchestration of antigen cross-presentation in antigen-presenting cells with innate stimulation. Here, we report a minimalist nanovaccine, comprising a simple physical mixture of an antigen and a synthetic polymeric nanoparticle, PC7A NP, which generates a strong cytotoxic T-cell response with low systemic cytokine expression. Mechanistically, the PC7A NP achieves efficient cytosolic delivery of tumour antigens to antigen-presenting cells in draining lymph nodes, leading to increased surface presentation while simultaneously activating type I interferon-stimulated genes...

The ARF protein functions as an important sensor of hyper-proliferative stimuli restricting cell proliferation through both p53-dependent and -independent pathways. Although to date the majority of studies on ARF have focused on its anti-proliferative role, few studies have addressed whether ARF may also have pro-survival functions. Here we show for the first time that during the process of adhesion and spreading ARF re-localizes to sites of active actin polymerization and to focal adhesion points where it interacts with the phosphorylated focal adhesion kinase...

Protein synthesis is crucial for regulating cell homeostasis and, when unrestricted, it can lead to tumorigenesis. Immunotoxins derived from Pseudomonas exotoxin are antibody-toxin fusion proteins that inhibit protein synthesis of mammalian cells via ADP-ribosylation of the eukaryotic elongation factor-2. Here we investigate the role of the Bcl-2 family proteins in the response of cancer cells to immunotoxin challenge. Besides the well-known reduction of the prosurvival Bcl-2 family member, Mcl-1, following inhibition of protein synthesis, we show for the first time that immunotoxins also reduce the levels of selected proapoptotic BH-3-only proteins...

BACKGROUND: Hispanic children with cancer experience poorer survival than their White counterparts. Infection is a known cause of cancer-related mortality; however, little is known about the risk of infection-related death among Hispanic children with cancer. We examine the association of Hispanic ethnicity with infection-related mortality and life-threatening events among children with cancer. PROCEDURE: For a cohort of all pediatric cancer patients diagnosed from 1986 to 2012 and treated at a single tertiary care center, we obtained national death records to determine all-cause mortality and infection-related mortality, as well as intensive care unit (ICU) admissions as a surrogate for life-threatening events...

INTRODUCTION: The prostate-specific antigen (PSA) screening test is controversial and can result in both over-diagnosis and over-treatment. Recently, the Canadian Task Force on Preventive Health Care (CTFPHC) has recommended against routine screening for prostate cancer. We sought to determine how the CTFPHC has impacted the practice patterns among family physicians in the North Simcoe Muskoka (NSM) Local Health Integration Network (LHIN). MATERIALS AND METHODS: We surveyed all 439 family physicians within the NSM LHIN as well as 21 residents of the Family Medical Teaching Unit...
