BACKGROUND: Spectrum effects refer to the phenomenon that test performance varies across subgroups of a population. When spectrum effects occur during diagnostic testing for cancer, difficult patient misdiagnoses can occur. Our objective was to evaluate the effect of test indication, age, gender, race, and smoking status on the performance characteristics of two commonly used diagnostic tests for bladder cancer, urine cytology and fluorescence in situ hybridization (FISH). METHODS: We assessed all subjects who underwent cystoscopy, cytology, and FISH at our institution from 2003 to 2012...

UNLABELLED: Amplification of the MET oncogene is associated with poor prognosis, metastatic dissemination, and drug resistance in many malignancies. We developed a method to capture and characterize circulating tumor cells (CTC) expressing c-MET using a ferromagnetic antibody. Immunofluorescence was used to characterize cells for c-MET, DAPI, and pan-CK, excluding CD45(+) leukocytes. The assay was validated using appropriate cell line controls spiked into peripheral blood collected from healthy volunteers (HV)...

This study investigated the effects of the long-term dietary fish oil supplementation or the acute administration of the omega-3 fatty acid docosahexaenoic acid (DHA) in the mouse hemorrhagic cystitis (HC) induced by the anticancer drug cyclophosphamide (CYP). HC was induced in mice by a single CYP injection (300mg/kg ip). Animals received four different diets containing 10% and 20% of corn or fish oil, during 21days. Separated groups received DHA by ip (1μmol/kg) or intrathecal (i.t.; 10μg/site) routes, 1h or 15min before CYP...

BACKGROUND & AIMS: Pancreatobiliary cancer is detected by fluorescence in situ hybridization (FISH) of pancreatobiliary brush samples with UroVysion probes, originally designed to detect bladder cancer. We designed a set of new probes to detect pancreatobiliary cancer and compared its performance with that of UroVysion and routine cytology analysis. METHODS: We tested a set of FISH probes on tumor tissues (cholangiocarcinoma or pancreatic carcinoma) and non-tumor tissues from 29 patients...

The RNA binding motif protein 38 (RBM38, also known as RNPC1) plays a pivotal role in regulating a wide range of biological processes, from cell proliferation and cell cycle arrest to cell myogenic differentiation. It was originally recognized as an oncogene, and was frequently found to be amplified in prostate, ovarian and colorectal cancer, chronic lymphocytic leukemia, colon carcinoma, esophageal cancer, dog lymphomas and breast cancer. In the present study, the complete RNPC1 gene was identified in a number of vertebrate genomes, suggesting that RNPC1 exists in all types of vertebrates, including fish, amphibians, birds and mammals...

BACKGROUND: The role of urine markers in the surveillance of patients with non-muscle invasive bladder cancer (NMIBC) is discussed extensively. In case of negative cystoscopy the additional prognostic value of these markers has not been clearly defined yet. The present study is the first systematic approach to directly compare the ability of a urine marker panel to predict the risk of recurrence and progression in bladder cancer (BC) patients with no evidence of relapse during surveillance for NMIBC...

Human epidermal growth factor receptor 2 (HER2) amplification/overexpression is an effective therapeutic target in breast and gastric cancer. Although HER2 positivity has been reported in other malignancies, previous studies generally focused on one cancer type, making it challenging to compare HER2 positivity across studies/malignancies. Herein, we examined 37,992 patient samples for HER2 expression (+/- amplification) in a single laboratory. All 37,992 patients were tested by immunohistochemistry (IHC); 21,642 of them were also examined for HER2 amplification with either fluorescent in situ hybridization (FISH) (11,670 patients) or chromogenic in situ hybridization (CISH) (9,972 patients); 18,262 patients had tumors other than breast or gastric cancer...

BACKGROUND: The optimal use of urine markers in the surveillance of non-muscle-invasive bladder cancer (NMIBC) remains unclear. Aim of the present study was to investigate the combined and stepwise use of the four most broadly available urine markers to detect tumor recurrence in patients undergoing surveillance of NMIBC. PATIENTS AND METHODS: 483 patients with history of NMIBC were included. Cytology, UroVysion, fluorescence in situ hybridization (FISH), immunocytology (uCyt+), and NMP22 ELISA were performed before surveillance cystoscopy...

BACKGROUND: The significance of a positive UroVysion FISH assay is uncertain in patients with normal cystoscopy. This multicenter study evaluates the clinical significance of a positive FISH assay in patients with no visible tumor and excluding those with a positive cytology. METHODS: A multi-institutional, retrospective study of patients with a history of urothelial carcinoma of the bladder identified 664 patients with a FISH assay after excluding those with cystoscopic evidence of a tumor and/or positive cytology...

UNLABELLED: Several types of cancer in fish are caused by retroviruses, including those responsible for major outbreaks of disease, such as walleye dermal sarcoma virus and salmon swim bladder sarcoma virus. These viruses form a phylogenetic group often described as the epsilonretrovirus genus. Epsilon-like retroviruses have become endogenous retroviruses (ERVs) on several occasions, integrating into germ line cells to become part of the host genome, and sections of fish and amphibian genomes are derived from epsilon-like retroviruses...

BACKGROUND: The aim of the study was to characterize a recurrent amplification at chromosomal region 1p21-22 in bladder cancer. METHODS: ArrayCGH (aCGH) was performed to identify DNA copy number variations in 7 clinical samples and 6 bladder cancer cell lines. FISH was used to map the amplicon at 1p21-22 in the cell lines. Gene expression microarrays and qRT-PCR were used to study the expression of putative target genes in the region. RESULTS: aCGH identified an amplification at 1p21-22 in 10/13 (77%) samples...

AIM: To examine the long-term follow-up of patients with that previously underwent risk stratification based on multicolour FISH testing. PATIENTS AND METHODS: On 81 patients with intermediate-risk urothelial carcinoma, a multicolour-FISH was performed. Patients were sub-divided into low- and high-risk groups based on chromosomal patterns. Univariate analysis, using Mantel-Cox log-rank test for disease-free, progression-free survival and overall survival, was employed to determine the prognostic significance of FISH analysis...

BACKGROUND: The cytologic diagnosis of urothelial carcinoma (UC) of the upper urothelial tract (UT) is challenging. Using the UroVysion probe set adds diagnostic value for the detection of bladder cancer in voided urine. In instrumented UT specimens, the authors encountered positive UT cytology and fluorescence in situ hybridization (FISH) cases that did not demonstrate subsequent UT carcinoma. METHODS: The performance of cytology and FISH in the presence or absence of concomitant bladder cancer within 2 years was compared in 61 patients (112 samples) from 2003 through 2009...

The marine antimicrobial peptide (AMP) GE33, also known as pardaxin, possesses antimicrobial and anticancer properties, and modulates host signaling. GE33 has cytotoxic effects on murine bladder carcinoma (MBT-2) cells. Here, we investigated the potential of GE33 combined with inactivated MBT-2 as a cancer vaccine. The presence of up to 12.5 μg of GE33 did not inhibit the proliferation or endogenous nitrous oxide (NO) levels of RAW264.7 cells. However, the secretion of MCP-1, IL-6, and IL-12 by RAW264.7 cells was affected by GE33...

Informative value of two tests based on FISH of exfoliated urothelial cells in urine sediment (AURKA and UroVysion) was compared in the group of patients (31 persons) with the history of bladder cancer. Coincidence in results of both FISH assays was found in 93.5%. These preliminary data offer the possibility of replacing expensive UroVysion kit by a cheaper AURKA FISH probe and it could be used for monitoring of recurrence in bladder cancer patients.
