Filter by:RATIONALE: Stop-smoking plans, including counseling and nicotine replacement therapy, may help smokers quit smoking. It is not yet known whether counseling and the nicotine lozenge is more effective than counseling and the nicotine patch in helping adult smokers quit smoking. PURPOSE: This randomized phase III trial is studying counseling and the nicotine lozenge to see how well they work compared to counseling and the nicotine patch in helping smokers quit smoking.
RATIONALE: Biological therapies, such as BCG, may stimulate the immune system in different ways and stop tumor cells from growing. Gefitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving BCG together with gefitinib may kill more tumor cells. It is not yet known whether BCG is more effective with or without gefitinib in treating bladder cancer. PURPOSE: This randomized phase III trial is studying BCG and gefitinib to see how well they work compared to BCG alone in treating patients with high-risk bladder cancer.
While the gold standard of treatment in invasive bladder cancer is surgical removal of the bladder, it is well accepted that a reasonable alternative is an organ preserving approach. Bladder preservation can be achieved in patients with radiotherapy alone or together with concurrent chemotherapy. This clinical trial will assess the potential of intensity modulated radiation therapy (IMRT) delivered using helical tomotherapy to reduce radiation-induced gastrointestinal toxicity and increase the accuracy of bladder cancer irradiation.
Data from the new cancer atlas covering the period 1974 1994 indicates that deaths from bladder cancer among white men and women are elevated in the northeastern United States, particularly the northern parts of New England. The reason for these elevated rates of incidence of and deaths from bladder cancer is unknown. Only part of the excess risk can be explained by exposure to the textile and leather industries. The purpose of this study is to determine the factors that contribute to the high rates of incidence of and death from bladder cancer in northern New England. The main objectives are to: - estimate the risk of developing bladder cancer associated with inorganic arsenic in drinking water, other water contaminants, tobacco use, occupational exposures, residential proximity to industrial sites, dietary factors, ethnicity, and use of wood-burning stoves. - estimate the extent to which water containing inorganic arsenic explains the increased rates of bladder cancer. - estimate the extent to which exposure to other risk factors explains the increased rates. - evaluate risk of bladder cancer according to genetic factors. - examine interactions of these factors with tobacco use, occupational exposure, and environmental exposure to arsenic and other compounds. All people ages 30 79 with confirmed cases of bladder cancer will be eligible for the study. Twelve hundred people with bladder cancer and twelve hundred individuals with no previous bladder cancer will be included. After potential participants are recruited and agreement is obtained over the telephone, they will complete a calendar and collect toenail clippings prior to the home interview. During the home visit, an investigator will administer a computer-assisted personal interview, collect drinking water samples and the clippings, and obtain a global positioning satellite reading. Other biological samples, such as saliva samples, urine, and blood, may be requested. Private wells at any previous homes of participants will also be sampled. The location of previous homes will be determined and the current homeowner will be asked to allow sampling of the well. The associations between bladder cancer and environmental exposures will be examined and the extent to which exposures to such risk factors explain the elevated mortality and incidence in northern New England will be estimated. ...
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: Exercise may help improve mobility and relieve fatigue and/or weakness in cancer survivors. It is not yet known whether exercise is more effective than standard therapy in improving mobility and reducing fatigue and/or weakness in older cancer survivors. PURPOSE: This randomized clinical trial is studying exercise to see how well it works compared to standard therapy in improving mobility and reducing fatigue and/or weakness in older cancer survivors.
The purpose of this study is to explore a treatment that potentially enhances the delivery of chemotherapy to tumors in participants with superficial bladder cancer. The investigational medication to be studied is an enzyme called ChemophaseTM (recombinant human hyaluronidase, rHuPH20). Chemophase is being specifically developed for use with other anticancer drug to increase the local penetration of the anticancer drug for the treatment of superficial bladder cancer. In this study, Chemophase will be given in combination with mitomycin C directly into the bladder. Mitomycin C is an anti-tumor drug that is commonly used to treat superficial bladder cancer. It is envisioned that Chemophase with mitomycin C may potentially increase the local penetration of mitomycin C into remaining cancer cells following surgery to treat superficial bladder cancer.
It is hypothesized that the NMP22(Nuclear Matrix Protein) Bladder Check ® Test will demonstrate improved sensitivity over that of standard urine cytology for patients with superficial transitional cell carcinoma at high risk of recurrence.
The purpose of this clinical trial is to evaluate the ability of urinary Survivin mRNA measurement to estimate the risk of bladder cancer at the time of cystoscopy in subjects with no prior history of bladder cancer presenting with microscopic or macroscopic hematuria.
The purpose of this clinical research study is to learn if patients who receive vinflunine plus best supportive care live longer than patients who receive best supportive care alone. This study will also investigate patient benefit, safety and whether or not vinflunine shrinks or slows the growth of the cancer.
