Filter by:Bladder carcinoma is the most common malignancy of the urinary tract. Approximately 75-85% of patients with bladder cancer present with a disease that is confined to the mucosa or submucosa. These categories are grouped as non-muscle-invasive bladder tumors(i.e. superficial tumors). Bladder cancer is the fifth most common cancer in the United States, with an estimated 67,160 newly diagnosed cases and 13,750 deaths in the United States in 2007. The 5-year survival rate is 82% for all stages combined. The standard of treatment for patients with superficial bladder cancer is surgical transurethal resection (TUR) of tumors, with an 80% early success rate. However, nearly 70% of these patients will develop tumor recurrence, with 25% showing progression to muscle-invading disease, within 5 years with TUR. It is therefore necessary to consider adjuvant therapy in all patients. The absolute risks of recurrence and progression do not always indicate the risk at which a certain therapy is optimal. The choice of therapy may be considered differently according to what risk is acceptable for the individual patient and the urologist. Intravesical chemotherapy and immunotherapy are widely used as adjuvant therapies after TUR, to prevent recurrence and progression of superficial disease. Systemic therapy is typically reserved for higher stage, muscle-invading, or metastatic diseases. The urinary bladder is an ideal organ for regional therapy. The urethra provides easy access of therapeutic agents to the urinary bladder. The presence of the specialized asymmetric unit membrane on the urothelium serves as a barrier and limits the absorption of molecules or particulates into the systemic circulation. The rationale for intravesical therapy is to maximize the exposure of tumors located in the bladder cavity to therapeutics agents while limiting the systemic exposure and thereby limiting the host toxicities; the primary goal is to eradicate existing or residual tumors through direct cytoablation or immunostimulation. The unique properties of the urinary bladder render it a fertile ground for evaluating novel approaches to regional therapy, including local hyperthermia, co-administration of permeation enhancers, bioadhesive carriers, and gene therapy. One of the developing treatments for high-risk superficial bladder cancers is the combination of intravesical chemotherapy and hyperthermia (HT), called chemohyperthermia (C-HT). The most common form of C-HT uses the Synergo HT system, in which local HT is administered via direct microwave irradiation of the urothelium by means of a 915-MHz intravesical microwave applicator. The target intravesical temperature is set between 41.8C and 44.8C and is measured by five thermocouples integrated in a 20-F treatment catheter. To avoid injury, the urethra is continuously cooled. Due to extensive global experience with its use and a significant amount of preclinical data demonstrating improved antineoplastic efficacy when heated, mitomycin C (MMC) is the most common intravesical chemotherapy agent used in conjunction with HT. The most common adverse events during treatment were bladder spasms and bladder pain. Literature reports bladder spasms in 21.6% of patients, and bladder pain in 17.5%. Bladder spasms tended to occur more frequently with the prophylactic schedule, whereas pain was present equally in the prophylactic and ablative schedules but more commonly after the ablative schedule. In the first days following C-HT, storage LUTS (frequency, dysuria, urgency, nocturia) (25.6%) and hematuria (6.0%) are the most common adverse events. Most studies mention that these symptoms were mild and transient, resolving spontaneously within a few days of treatment. One study described severe cystitis complaints in three patients (16%), but other studies have not confirmed these adverse events. Two studies report the development of a contracted bladder and severe urinary incontinence after ablative C-HT. However, the possibility cannot be excluded that previous transurethral resection and intravesical chemotherapy might have contributed to this event. Following the appearance of bothersome storage LUTS, patient should be managed by existing guidelines. Based on AUA/SUFU Diagnosis and Treatment of Overactive Bladder (Non-Neurogenic) in Adults Guidelines published in 2012 patients should be diagnosed, followed and treated according to the suggested algorithm. In our study, we would like to assess the severity of OAB symptoms and their response to a standard OAB treatment according to AUA Guidelines for Non-neurogenic OAB as well as to assess urodynamic study variables in those who didn't respond to a standard medical treatment and bothered by their OAB symptoms.
This phase II trial studies how well modern, conformal radiation therapy after surgery works in treating patients with high-risk bladder cancer. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.
Baobab oil is often used in traditional medicine as antipyretic, antioxidant, anti-inflammatory, analgesic and antimicrobial. It also regenerates the epithelial tissue in a short time improving tone and elasticity. We want to evaluate the effects of intravesical Baobab oil in patients with BCG-induced lower urinary tract symptoms.
This phase I/II trial studies the side effects and best dose of sirolimus when given together with cisplatin and gemcitabine hydrochloride and to see how well they work in treating patients with bladder cancer. Biological therapies, such as sirolimus, may stimulate or suppress the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as cisplatin and gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving sirolimus together with cisplatin and gemcitabine hydrochloride may be an effective treatment for bladder cancer.
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.
This is a prospective study of pretreatment DW-MRI to identify potential imaging biomarkers predictive of response to neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer. Target enrollment of this study is 40 patients. Patients will first undergo baseline DW-MRI of the Abdomen and Pelvis prior to beginning standard treatment with neoadjuvant cisplatin-based chemotherapy after which DW-MRI will be repeated to assess for response or progression. Patients who remain eligible for surgery will proceed to standard radical cystectomy with pelvic lymph node dissection. DW-MRI metrics including apparent diffusion coefficient (ADC) values will be correlated to pathologic response rate in the radical cystectomy specimen to identify imaging markers predictive of response.
In laboratory and clinical studies, intravesical electromotive drug administration increased mitomycin bladder uptake, improving clinical efficacy in high-risk non-muscle invasive urothelial bladder cancer. The investigators' aim was to compare transurethral resection of bladder tumor and adjuvant intravesical electromotive mitomycin with transurethral resection and adjuvant intravesical passive diffusion mitomycin and transurethral resection alone in patients with primary stage pTa-pT1 and grade G1-G2 urothelial bladder cancer Patients will be randomly assigned to: transurethral resection alone, transurethral resection and adjuvant intravesical 40 mg passive diffusion mitomycin dissolved in 50 ml sterile water infused over 60 minutes once a week for 6 weeks, or transurethral resection and adjuvant intravesical 40 mg electromotive mitomycin dissolved in 100 ml sterile water with 23 mA pulsed electric current for 30 minutes once a week for 6 weeks. Patients in the intravesical adjuvant electromotive and passive diffusion mitomycin groups who are disease-free 3 months after induction treatment, will be scheduled to receive monthly intravesical instillation for 10 months, with the same dose and methods of infusion as initial assigned treatment. All patients will be assessed for safety. The investigators' primary endpoints are recurrence rate and disease-free interval. Analyses will be done by intention to treat.
Muscle invasive bladder cancer is an aggressive malignancy. Currently the investigators lack accurate imaging technologies in clinical staging and estimation of response to neoadjuvant chemotherapy as well as prognostic biomarkers. In the current study novel imaging modality (MRI/PET) is utilized to stage bladder cancer prior to transurethral resection of bladder-tumor and after neoadjuvant chemotherapy. Also prognostic biomarkers are studied from TUR-BT tissues, blood and urine to estimate response to neoadjuvant chemotherapy.
The purpose of this study is to find out if using the combination of standard chemotherapy (gemcitabine and carboplatin) plus this new drug (panitumumab) can help to shrink the tumor before the patient undergoes surgery for bladder cancer.
The study main objectives are to enhance treatment decision making and improve quality of life and post-treatment health care among patients diagnosed with invasive bladder cancer. Bladder cancer (BL Ca) is the 5th most commonly diagnosed cancer in the US . BL Ca is more common among men than women and 90% of all patients are over the age of 55. Surgery to remove the bladder followed by one of three diversion techniques (i.e., ileal conduit, continent reservoir, and neobladder) is the standard therapy following invasive bladder cancer. The emotional, functional, physical, and social impact of invasive Bl Ca treatment on patients' QOL and adjustment can be devastating. This impact significantly varies by treatment option. Treatment decision making in for BL Ca is difficult at best and potentially susceptible to a number of cognitive and affective factors (e.g., patients' emotional reaction, values, and expectations). Thus, in addition to adjusting to a potential life-threatening disease, having to cope with uncertainty about the efficacy and outcomes of different treatment options adds to the overall distress and may impair effective decision-making. In spite of increasing efforts in health communication and patient education, no study has examined treatment decision making among invasive bladder patients or has provided an educational intervention to facilitate treatment decision making among this population. To this end, and guided by the Self-Regulation theory (SRT) that emphasizes the role of cognitive and emotional factors in decision making, we have designed and pilot tested the acceptability of a preliminary educational and training experiential intervention (ETE) to address this gap in the literature. The ETE intervention uses new and innovative educational strategies and methods to educate patients about their treatment options and to facilitate their treatment decision making.
