Active clinical trials for "Urinary Bladder Neoplasms"

In patients undergoing spinal anesthesia, the investigators used an Infra-red camera and a respiratory volume monitor to determine the accuracy of the ventilation rate of the infra red camera by measuring the respiratory rate, ventilation volume, and ventilation volume with respiratory volume monitor.

The investigators hypothesize that circulating tumor cells (CTC) will be observed in patients with muscle-invasive or metastatic bladder cancer and that CTC will become undetectable, at least transiently, in a fraction of patients after treatment. To investigate this hypothesis, investigators will assess the levels of CTCs both before and after treatment. The feasibility and potential value of fluorescent in situ hybridization (FISH) in the CTCs will be assessed.

RATIONALE: Learning about quality of life and symptom management in patients with bladder cancer may help doctors learn about the effects of treatment and plan the best treatment. PURPOSE: This clinical trial is studying of quality of life and symptom management in patients with bladder cancer.

The purpose of this study is to determine the effectiveness of hexaminolevulinate (Hexvix) in the diagnosis and treatment of patients with non-invasive bladder cancer and if it results in a change in patient management.

The incidence rate of bladder cancer in the Barcelona area of Spain is almost identical to that of the U.S. Cigarette smoking has been identified as the most significant risk factor for bladder cancer, followed by occupational exposures to chemicals such as aromatic amines and their derivatives, diesel exhaust, oil mist, pesticides, and polynuclear aromatic hydrocarbons. A variety of non-occupational exposures have been suggested as potential risk factors as well, including smoking black vs. blond tobacco, dietary factors, certain medications and medical conditions, chlorination by-products in drinking water, and fluid intake. Various genetic polymorphisms also appear to affect bladder cancer risk. Research is needed to further explore hypotheses generated by previous etiologic studies of bladder cancer. An on-going study of bladder cancer survival by the Institut Municipal d'Investigacio Medica in Spain provides an excellent opportunity for NCI to perform such research. NCI will build upon the ongoing study by funding an interdisciplinary case-control component to evaluate bladder cancer risk in relation to various external factors (e.g., occupational and environmental exposure) and host factors (e.g., genetic susceptibility markers, and early effect markers). This hospital-based case-control study will involve personal interviews using a state-of-the-art, computer assisted technique, and collection of blood and toenail samples from participants.

RATIONALE: Motivational counseling may help prevent pregnant women from smoking again after pregnancy. PURPOSE: This randomized clinical trial is studying three different types of counseling to see how well they work in preventing smoking relapse after pregnancy in pregnant women who quit smoking during pregnancy.

RATIONALE: Studying samples of blood and urine from patients with cancer and from healthy participants in the laboratory may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This laboratory study is looking at biomarkers in patients with kidney cancer or cancer of the urothelium and in healthy participants.

This study is examining the relationship between ingested arsenic and bladder cancer in two areas of California where a large percentage of the population was exposed to drinking water containing arsenic at low to moderate levels.

The study is a pilot study in the feasibility of a diagnostic technique. There is no current data on detection of cisplatin in cancer cells derived from human urine. This study will generate preliminary data so that future studies may be done with more definitive end points in mind.

In this pilot study, a total of 80 patients with prostate or bladder cancer (40 black, 40 white) will complete 3 patient-reported outcome (PRO) surveys: baseline (pre-treatment), during treatment, and after treatment. The overall goal of this study is to assess whether collecting patient-reported data is feasible as part of clinical care of cancer patients, and whether these data are useful for clinicians and patients. Among these 80 patients, those who agree will also undergo a semi-structured interview to assess value of HRQOL assessment at the end of the study. Of specific interest is an evaluation of whether feasibility and perceived value differ between black and white participants.
