Lei Sun, Fen Zhao, Yan Zeng, Cheng Yi
BACKGROUND Esophageal cancer has traditionally been associated with very poor outcomes. A number of therapies are available for the treatment and palliation of esophageal cancer, but little systematic evidence compares the efficacy of different treatment strategies. This meta-analysis aimed to investigate whether treatments in addition to radiotherapy could provide better efficacy and safety. MATERIAL AND METHODS We identified a total of 12 eligible studies with 18 study arms by searching PubMed, the Cochrane Library, EMBASE, and Clinical Trials...

BACKGROUND: Support for the oncological safety of oncoplastic breast conservation surgery (OBCS) is mostly based on evidence comparing recurrence rates after OBCS to wide local excision (WLE). However, OBCS is often indicated for larger cancers and oncological results should also be compared to patients treated with mastectomy. In this study we compared recurrence and survival following OBCS, mastectomy and WLE. METHODS: Patients treated with OBCS between 2009 and 2012 were identified from a prospectively maintained database...

BACKGROUND: Reproductive and lifestyle factors influence both breast cancer risk and prognosis; this might be through breast cancer subtype. Subtypes defined by immunohistochemical hormone receptor markers and gene expression signatures are used to predict prognosis of breast cancer patients based on their tumour biology. We investigated the association between established breast cancer risk factors and the 70-gene prognostication signature in breast cancer patients. PATIENTS AND METHODS: Standardised questionnaires were used to obtain information on established risk factors of breast cancer from the Dutch patients of the MINDACT trial...

BACKGROUND: The molecular diagnosis of brain tumors is important in classifying tumors and determining appropriate treatment. Congenital glioblastoma multiforme (GBM) is a rare tumor that occurs in infants, and the prognosis is poor. Approximately 60 patients diagnosed as congenital GBM have been reported. However, few reports have conducted molecular analyses of congenital GBM. CASE DESCRIPTION: We describe two congenital GBM patients treated in our hospital, and report results of immunohistochemistry, fluorescent in situ hybridization (FISH), direct sequencing, and methylation analyses...

BACKGROUND: Solid tumours are less oxygenated than normal tissues. Consequently, cancer cells acquire to be adapted to a hypoxic environment. The poor oxygenation of solid tumours is also a major indicator of an adverse cancer prognosis and leads to resistance to conventional anticancer treatments. We previously showed the involvement of Che-1/AATF (Che-1) in cancer cell survival under stress conditions. Herein we hypothesized that Che-1 plays a role in the response of cancer cells to hypoxia...

The identification and understanding of the molecular network of cancer stem cells (CSCs) have had a profound impact on our view of carcinogenesis and treatment strategy. Unfortunately, a major problem is that serial passages of CSCs from clinical solid tumor specimens currently are not available in any lab, and thus, reported data are difficult to confirm and intensively interrogated. Here, we have generated two tumor tissue-derived breast CSC (BCSC) lines that showed prolonged maintenance over 20 serial passages in vitro, while retaining their tumor-initiating biological properties...

PURPOSE: Intensity modulated radiotherapy for prostate cancer involves daily monitoring of the positioning of the prostate, possible with cone beam CT (CBCT). It allows increased accuracy compared to readjustments but induces an increase in the time dedicated to these medical checks. The aim of the study was to evaluate the possibility of delegation of this task to the radiation therapists by comparing their readjustments to the doctors. PATIENTS AND METHODS: Five consecutive patients treated with radiation for prostate cancer (76Gy) were analysed...

PURPOSE: Venous thromboembolism (VTE) is the leading cause of noncancer death following major cancer surgery. Current thromboprophylaxis guidelines do not address procedure-specific risk of venous thromboembolism for urological patients. This project was created to determine the risk and timing of VTE after major urological surgery and to evaluate if surgical procedure was an independent risk factor for VTE after adjusting for previously established risk factors. MATERIAL AND METHODS: The American College of Surgeons׳ National Surgical Quality Improvement Program was used to create a cohort of patients who received major abdominal or pelvic urologic surgery between 2006 and 2014...

PURPOSE: Abnormal spindle microtubule assembly (ASPM) gene was known to be linked with poor clinical prognosis in various tumors. However, the clinical significance of ASPM in prostate cancer (PCa) has not yet been understood. The purpose of this study was to determine the association of ASPM with tumor progression and prognosis in PCa patients. METHODS: The expression of ASPM at protein level in human PCa and non-cancerous prostate tissue was detected by immunohistochemical analysis, which was further validated by using microarray-based dataset (NCBI GEO: GSE21032 and The Cancer Genome Atlas (TCGA) dataset) at mRNA level...

PURPOSE: The ER-/PR-/HER2- or triple-negative (TNBC) subtype is more prevalent among women who are young, black, Hispanic, and of lower SES. The purpose of this study is to determine if young age and low SES are associated with TNBC within four mutually exclusive race/ethnicities. METHODS: The study identified 19,283 cases of TNBC and 89,089 of ER+/PR+/HER2- from the California Cancer Registry. Logistic regression analyses were conducted separately for whites, blacks, Hispanics, and Asian/Pacific Islanders (API) to compute the adjusted odds ratios (OR) for age and SES for the TNBC versus the ER+/PR+/HER2- subtype...

INTRODUCTION: The health information needs, information source preferences and engagement behaviours of women with metastatic breast cancer (mBC) depend on personal characteristics such as education level, prior knowledge, clinical complications, comorbidities and where they are in the cancer journey. A thorough understanding of the information behaviours of women living with mBC is essential to the provision of optimal care. A preliminary literature review suggests that there is little research on this topic, but that there may be lessons from a slightly broader literature...

REVIEW
N D Amoedo, E Obre, R Rossignol
The search for new drugs capable of blocking the metabolic vulnerabilities of human tumors has now entered the clinical evaluation stage, but several projects already failed in phase I or phase II. In particular, very promising in vitro studies could not be translated in vivo at preclinical stage and beyond. This was the case for most glycolysis inhibitors that demonstrated systemic toxicity. A more recent example is the inhibition of glutamine catabolism in lung adenocarcinoma that failed in vivo despite a strong addiction of several cancer cell lines to glutamine in vitro...
