BACKGROUND The neutrophil-lymphocyte ratio (NLR) has been proposed as an indicator of systemic inflammatory response. Several studies suggest a negative impact of increased NLR for patient's survival in different types of cancer. However, previous findings from small-scale studies revealed conflicting results about its prognostic significance with regard to(More)
BACKGROUND The neutrophil-lymphocyte ratio (NLR) has been proposed as an indicator of systemic inflammatory response. Previous findings from small-scale studies revealed conflicting results about its independent prognostic significance with regard to different clinical end points in pancreatic cancer (PC) patients. Therefore, the aim of our study was the(More)
BACKGROUND Inflammation has a critical role in the pathogenesis and progression of cancer. The lymphocyte to monocyte ratio (LMR) could be shown to be prognostic in haematologic neoplasia. In this study, we analysed the LMR with clinical outcome in stage II and III colon cancer patients. METHODS Three hundred and seventy-two patients with stage II and III(More)
BACKGROUND Molecular characterization of circulating tumor cells (CTCs) is pivotal to increasing the diagnostic specificity of CTC assays and investigating therapeutic targets and their downstream pathways on CTCs. We focused on epidermal growth factor receptor (EGFR) and genes relevant for its inhibition in patients with colorectal cancer (CRC). METHODS(More)
Circulating tumor cells (CTC) released into blood from primary cancers and metastases reflect the current status of tumor genotypes, which are prone to changes. Here, we conducted the first comprehensive genomic profiling of CTCs using array-comparative genomic hybridization (CGH) and next-generation sequencing. We used the U.S. Food and Drug(More)
OBJECTIVE To investigate the potential prognostic significance of the neutrophil-lymphocyte ratio (NLR) in a large European cohort of patients with upper urinary tract urothelial cell carcinoma (UUT-UCC). PATIENTS AND METHODS We retrospectively evaluated data from 202 consecutive patients with non-metastatic upper urinary tract urothelial cell carcinoma(More)
AIMS miR-181a expression is frequently altered in different types of cancer. Members of the Wnt/β-catenin signalling pathway, which is commonly altered in colorectal cancer (CRC), have been reported as molecular interaction partners of miR-181. However, the role of miR-181a expression in CRC and its ability to predict survival and response to agents(More)
Photodynamic therapy (PDT) is a local tumour treatment accepted for a number of indications. PDT operates via the cellular stress response through the production of reactive oxygen species and subsequent cellular damage, resulting in cell death. Although PDT-induced signalling and cytotoxicity mechanisms have been investigated, the effect of PDT on microRNA(More)
The central dogma of molecular biology states that the flow of genetic information moves from DNA to RNA to protein. However, in the last decade this dogma has been challenged by new findings on non-coding RNAs (ncRNAs) such as microRNAs (miRNAs). More recently, long non-coding RNAs (lncRNAs) have attracted much attention due to their large number and(More)
High-resolution melting (HRM) analysis is a novel tool for analysis of promoter methylation. The aim of the present study was to establish and validate HRM analysis for detection of promoter methylation on archival formalin-fixed paraffin-embedded tissues from colorectal cancer patients. We first evaluated HRM assays for O(6)-methylguanine-DNA(More)
