Active clinical trials for "Urinary Bladder Neoplasms"

Very few factors may be identified as prognostic for patients with bladder cancer undergoing radical cystectomy. Recently, detection of circulating tumor cells has shown to be very promising in anticipating both the likelyhood of distant metastases and survival in patients with breast cancer, melanoma, prostate cancer and other malignancies. In the present study we both tested the detection rate of circulating tumor cells using a PCR based methodology in the peripheral blood of patients undergoing radical cystectomy, and we further correlated our results with their clinical outcome.

The purpose of the study is to investigate sexual function in patients suspected of non muscle invasive bladder cancer (NMIBC). The investigators hypothesis is that reduced sexual function is underdiagnosed in patients with non-muscle invasive bladder cancer and that active examination and treatment may worsen the sexual function.

This is an observational study utilizing a qualitative descriptive methodology with a thematic analysis approach to explore the impact of a preoperative educational intervention ("Stoma Bootcamp") on patients and their family/informal caregivers

To assess the potential association between pioglitazone and bladder cancer compared with non-pioglitazone users among patients with type 2 diabetes mellitus.

Pioglitazone, an agonist of the peroxisome-proliferator-activated receptor (PPAR), is a relatively new oral anti-hyperglycemic drug. Since its first approval in the USA in 1999, a potential link with bladder cancer has been a subject of debate. US Food and Drug Administration (FDA) in September, 2010 and European Medicines Agency in July, 2011 issued an alert about a potential relation between the occurrence of bladder cancer and the prescription of pioglitazone, based on the data from various studies. France banned its use in July 2011. Recently Pioglitazone was banned from India without any evidence of increased bladder cancer in our population. With this background, we plan to study the risk of bladder cancer in male type 2 diabetes subjects aged more than 50 years who are on pioglitazone therapy as compared to never-users of pioglitazone in a retrospective cohort design and provide the first data from India to the policy makers regarding the purported risk in our ethnicity and geographical area.

The purpose of this pilot study is to develop the methodology for an innovative subsurface imaging technology that was designed at Lawrence Livermore National Laboratory. It will allow the non-invasive analysis and imaging of tissues and chemical distributions in the body at an imaging depth of up to 1 centimeter with spatial resolution on the order of 1 mm.

High doses of gabapentin are associated with pancreatic acinar cell tumors in rats, but there has been no post marketing pancreatic carcinogenicity signal with gabapentin as reported by spontaneous reports in AERS or in the published literature. In a published case-control screening study of the association of gabapentin with 55 cancers, the only cancer that met the screening criteria for possibly increased cancer risk with gabapentin exposure was renal (including renal pelvis) cancer. This association was judged to be likely due to or substantially accentuated by confounding by cigarette smoking, hypertension, and lifestyle (Cancer Causes Control 2009;20:1821-1835). The relationship between gabapentin exposure and pancreatic cancer and renal cancer is studied in NCT01138124, and supplemental analyses for these cancers are performed in the current study. The FDA recommended GSK also study the relationship between gabapentin and all-cancer sites, as well as cancer at the following specific sites: 1) stomach, 2) anus, anal canal, and anorectum, 3) lung and bronchus, 4) bones and joints, 5) breast, 6) penis, 7) urinary bladder, and 8) other nervous system. The primary objective of this study is to determine whether exposure to gabapentin is associated with an increased risk of developing all-cancer, and these specific cancers in the United Kingdom (UK) General Practice Research Database (GPRD). Each member of the UK population is registered with a General Practice, which centralizes the medical information not only from the general practitioners themselves but also from specialist referrals and hospital attendances. Over 487 General Practices contribute data to the GPRD. The study cohort from which cases and controls are drawn is all subjects in the GPRD 1993-2008. Gabapentin was approved in the UK in May 1993. Entry into the study cohort begins Jan 1, 1993 for all those who are registered in GPRD before that time, and at the time of registration if later than Jan 1, 1993. Subjects are excluded from the GPRD cohort if they have a cancer diagnosis or a history of cancer prior to the cohort entry date. Patients with a first diagnosis of the respective cancer 1995-2008 are risk set matched with up to 10 controls within the same General Practice for age at cohort entry (within two years), sex, and year of entry into the study cohort (within one year). For cases, the index date is the date of first diagnosis of the respective cancer. The index date for controls is set as the date at which the follow-up time from cohort entry is the same as the case. The index date is chosen so as to give the control equal follow-up time to that of the case for ascertainment of use of gabapentin. Cases and controls will be required to have at least 2 years of follow-up in the study cohort before their index date. Cases must have no history of any other cancer diagnosis prior to the index date. Controls are required to be free of cancer diagnosis in the database up to the control's index date. Data on gabapentin prescriptions are obtained for cases and controls from study cohort entry to the index date. Gabapentin exposure will be assessed as ever/never, number of prescriptions, cumulative dose, and cumulative duration, with a 2 year lag period incorporated to control for protopathic bias (gabapentin prescription for initial pain symptoms of undiagnosed cancer) and latency (time between cancer onset and specific GPRD cancer diagnosis). Crude and adjusted odds ratios and 95% confidence intervals (CI) will be produced from conditional logistic regression models, with additional analyses evaluating for dose-response. Covariates include indications for gabapentin use and risk factors for each cancer.

The purpose of this study is to identify aspects of the bladder cancer (BlCa) survivorship experience that differ by clinical risk at diagnosis. The investigators will collect cross-sectional data from persons with BlCa to identify aspects of health-related quality of life (HRQOL) and symptom management. The study originally enrolled only nonmuscle-invasive bladder cancer survivors but has been expanded to include survivors with any stage disease. Information from this study will be used to develop a new patient education and counseling intervention.

This is a multicenter, international, prospective, observational study of patients who are receiving systemic chemotherapy for solid tumour cancers (breast, colorectal, ovarian, prostate, lung, bladder, endometrial, renal, pancreatic, esophageal or gastric) and who are receiving darbepoetin alfa (Aranesp®) or other erythropoiesis-stimulating agent (ESA) to treat symptomatic anaemia. Quality of Life will be assessed electronically with the aim of estimating improvement in quality of life for those patients receiving darbepoetin alfa (Aranesp®) who also have an increase in haemoglobin (Hb) of ≥1 g/dL

Is BladderLight® (BL) urine testing accurate, as a non-invasive method, to exclude presence of bladder cancer in patients.
