Vascular mimicry (VM) refers to the plasticity of aggressive cancer cells forming de novo vascular networks, which promoted tumor metastasis. The aim of this study was evaluate the impact of VM on recurrence-free survival (RFS) in urothelial carcinoma of the bladder (UCB). Records from 202 patients treated with radical cystectomy (RC) for UCB at Zhongshan Hospital between 2002 and 2014 were reviewed. The presence of VM was identified by CD31-PAS double staining. Positive VM staining occurred in 19.3% (39 of 202) UCB cases, and it was associated with increased risks of recurrence (Log-Rank p<0...

Myoferlin is a multiple C2-domain-containing protein that regulates membrane repair, tyrosine kinase receptor function and endocytosis in myoblasts and endothelial cells. Recently it has been reported as overexpressed in several cancers and shown to contribute to proliferation, migration and invasion of cancer cells. We have previously demonstrated that myoferlin regulates epidermal growth factor receptor activity in breast cancer. In the current study, we report a consistent overexpression of myoferlin in triple-negative breast cancer cells (TNBC) over cells originating from other breast cancer subtypes...

BACKGROUND: Guidelines recommend endosonography with fine-needle aspiration for mediastinal nodal staging in non-small-cell lung cancer, but most do not specify whether this should be through endobronchial endoscopy (EBUS), oesophageal endoscopy (EUS), or both. We assessed the added value and diagnostic accuracy of the combined use of EBUS and EUS. METHODS: For this systematic review and random effects meta-analysis, we searched MEDLINE, Embase, BIOSIS Previews, and Web of Science, without language restrictions, for studies published between Jan 1, 2000, and Feb 25, 2016...

Tumors exert suppressive effects on the host immune system and tumor progression can be linked to functional impairments of immune cells. Regulatory T cells (Treg) are a subpopulation of T lymphocytes and play a key role in suppressing immune responses against autoimmune diseases and cancer. The aim of the study was to investigate the prevalence of Treg in malignant and benign pleural effusions and to evaluate the relationship between Treg frequency and disease advance. Pleural effusions from 76 patients were subjected to a routine laboratory diagnosis and analyzed by conventional cytology...

Video-assisted mediastinoscopy (VAM) is the most commonly used invasive method for the preoperative mediastinal staging of lung cancer and for the diagnosis of other mediastinal diseases. However, VAM has the risk of causing life-threatening bleeding consequent to the specific mediastinal anatomy. We adopted the ultrasonic technique for VAM biopsies that can easily distinguish the lymph nodes from the surrounding great vessels and thus makes the procedure easier and safer.

Testis specific protein Y-encoded (TSPY) is a Y-located proto-oncogene predominantly expressed in normal male germ cells and various types of germ cell tumor. Significantly, TSPY is frequently expressed in somatic cancers including liver cancer but not in adjacent normal tissues, suggesting that ectopic TSPY expression could be associated with oncogenesis in non-germ cell cancers. Various studies demonstrated that TSPY expression promotes growth and proliferation in cancer cells; however, its relationship to other oncogenic events in TSPY-positive cancers remains unknown...

A highly sensitive impedimetric bio-chip based on vertically aligned multiwall carbon nanotubes (VAMWCNTs), was applied in direct interaction with lung cancer cells. Our tool provided both inducing and monitoring the bioelectrical changes in the cells initiated by electromagnetic (EM) wave stimulation. EM wave of 940MHz frequency with different intensities was used. Here, wave ablation might accumulate electrical charge on the tips of nanotubes penetrated into cell's membrane. The charge might induce ionic exchanges into the cell and cause alterations in electrical states of the membrane...

BACKGROUND: Triple Negative Breast Cancer (TNBC) is defined by a lack of estrogen and progesterone receptor gene expression and by the absence of overexpression on HER2. It is associated to a poor prognosis. We propose to analyze the clinicopathologic and prognostic characteristics of this breast cancer subtype in a Mediterranean population originated or resident in the North of Morocco. METHODS: We conducted a retrospective study of 279 patients diagnosed with breast cancer between January 2010 and January 2015...

Lung cancer is the most common reason of cancer deaths and about 85% of these are non-small-cell lung cancer. Currently, lung cancer therapy is mainly based on the tumor node metastasis (TNM) disease staging and tumor histological classification. Despite therapeutic innovations, the prognosis for lung cancer patients has not significantly changed in the last years. Therefore, a proper understanding of cell signaling pathways involved in cancer pathogenesis seems to be essential for improvement in cancer therapy field...

INTRODUCTION: Many extrathoracic malignancies can metastasize to lungs and mediastinal lymph nodes. Whether mediastinal lesions are metastasis in these patients changes staging, prognosis, and treatment strategy. In this study, we aimed to find out the contribution of EBUS-TBNA to the diagnosis in cases with extrathoracic malignancy. MATERIALS AND METHODS: Patients who had been previously diagnosed as extrapulmonary solid organ malignancy and in whom mediastinal or hilar lymphadenopathy developed during their follow-up and EBUS-TBNA was applied for diagnostic purposes were retrospectively included in this study...

PURPOSE: Bone marrow derived progenitor cells; including VEGFR2+ endothelial progenitor cells (EPCs) and copper-dependent pathways model the tumor microenvironment. We hypothesized that copper depletion (CD) using tetrathiomolybdate (TM) would reduce EPCs in high risk for relapse breast cancer (BC) patients (pts). We investigated the effect of TM on the tumor microenvironment in preclinical models. EXPERIMENTAL DESIGN: Stage 2 triple negative BC (TNBC), Stage 3 and stage 4 without any evidence of disease, (NED) BC pts, received oral TM to maintain ceruloplasmin (Cp) between 8-17mg/dL for 2 years or until relapse...

Lung cancer has the highest mortality rate among cancer patients in the world, in particular because most patients are only diagnosed at an advanced and non-curable stage. Computed tomography (CT) screening on high-risk individuals has shown that early detection could reduce the mortality rate. However, the still high false-positive rate of CT screening may harm healthy individuals because of unnecessary follow-up scans and invasive follow-up procedures. Alternatively, false-negative and indeterminate results may harm patients due to the delayed diagnosis and treatment of lung cancer...

Even with all improvements in both diagnostic and therapeutic techniques, lung cancer remains as the most lethal and prevalent cancer in the world. Therefore, new therapeutic drugs and new strategies of drug combination are necessary to provide treatments that are more efficient. Currently, standard therapy regimen for lung cancer includes platinum drugs, such as cisplatin, oxaliplatin, and carboplatin. Besides of the better toxicity profile of oxaliplatin when compared with cisplatin, peripheral neuropathy remains as a limitation of oxaliplatin dose...

Stereotactic ablative radiation therapy (SABR) has become the standard treatment for peripheral medically non-operable patients with early stage non-small cell lung cancer (NSCLC). Previous attempts of trials to compare SABR and surgery have failed and new randomized studies (SABRtooth, STABLEMATES, and VALOR) are ongoing. While predictive factors of relapse have been extensively studied in patients receiving surgery, there is scarce data on such putative factors in SABR patients. The purpose of this review is to analyze such predictive factors through a critical review of the literature...

This study was conducted to investigate whether polymorphisms of genes involved in glycolysis are associated with the prognosis of patients with non-small cell lung cancer (NSCLC) after surgical resection. Forty-four single nucleotide polymorphisms (SNPs) of 17 genes in glycolytic pathway were investigated in a total of 782 patients with NSCLC who underwent curative surgical resection. The association of the SNPs with overall survival (OS) and disease free survival (DFS) were analyzed. Among the 44 SNPs investigated, four SNPs (ENO1 rs2274971A > G, PFKM rs11168417C > T, PFKP rs1132173C > T, PDK2 rs3785921G > A) were significantly associated with survival outcomes in multivariate analyses...
