Filter by:Early single instillation of chemotherapy after TUR is recommended in the European Association of Urology Guidelines. Nevertheless, the procedure is suboptimal for patients with multiple tumors, sometimes is not tolerated and it can results in severe complications. In both laboratory and clinical studies, intravesical electromotive drug administration (EMDA) increases mitomycin-C (MMC) bladder uptake, resulting in an improved clinical efficacy in non-muscle invasive bladder cancer (NMIBC). The investigators will compare the effects of one immediate pre-TUR intravesical EMDA/MMC instillation with one immediate post-TUR intravesical passive diffusion MMC (PD/MMC) instillation and TUR alone in patients with NMIBC. All eligible patients with primary NMIBC will be randomized into 3 groups who will undergo transurethral resection alone (TUR/alone); TUR plus single immediate postoperative instillation (immediately after TUR) of 40 mg PD/MMC with a dwell time of 60 minutes; or single immediate preoperative instillation (immediately before TUR) of 40 mg EMDA/MMC with 20 mA electric current for 30 minutes. Patients with intermediate and high risk NMIBC will undergo adjuvant intravesical therapy. The primary end points will be the recurrence rate and disease-free interval. All clinical analyses will be performed on an intent to treat basis.
The purpose of this research study is to test the safety and tolerability of an experimental drug, Chemophase, a combination of recombinant human hyaluronidase, (an investigational synthetic enzyme also known as rHuPH20), and mitomycin (MMC) in the treatment of superficial bladder cancer when instilled intravesically immediately after TURBT (transurethral resection of bladder tumor).
Hypothesis: In selected patients external hyperthermia will be used in combination with intravesical Mitomycin-C (MMC) to treat recurrent transitional cell carcinoma (TCC) of the bladder after local resection and standard adjuvant therapy and thus prevent or delay recurrence and the need for radical cystectomy.
This study is designed to assess the efficacy and safety of DTA-H19/PEI given as six intravesical instillations of 20 mg of plasmid DNA complexed with PEI into the bladder of patients with intermediate risk superficial bladder cancer [recurrent stages Ta (low or high grade)and T1, (low grade) transitional cell carcinoma (TCC)] who have failed prior intravesical therapies including either Bacillus Calmette-Guérin (BCG) or chemotherapy. The primary efficacy objective is to determine the effect of DTA-H19/PEI on the prevention of new tumors after the induction course of 6 weekly intravesical administrations of investigational product assessed 8 to 10 weeks after the start of treatment. Secondary objectives include assessing the ablative effect of DTA-H19/PEI on a marker tumor, safety assessed by the incidence and severity of adverse events, determining the long-term (46 weeks) continued rates of absence of bladder cancer, and time to tumor recurrence in those patients who had a complete response (CR) after the induction course.
This protocol is evaluating efficacy and toxicity of three sequential whole bladder photodynamic treatment with Photofrin and red laser light (630 nm) in the management of superficial bladder cancer (non-muscle invasive) in those patients who have failed or are not candidates for conventional intravesical therapy.
Gemcitabine has been shown to be highly effective and well tolerated in the first and second line therapy, as a single agent or in combination therapy for treatment of metastatic transitional cell carcinoma. On the basis of Gemcitabine clinical activity and good tolerability this drug has been recently tested in intravesical therapy. we consider Gemcitabine as a good therapy candidate for patient with intermediate risk superficial bladder cancer. Based on the phase I/II clinical trials w are going to explore the efficacy and tolerability of Gemcitabine in this setting, and compare it to Mitomycin C which is widely used in this group of patients.
The purpose of this study is to determine whether neoadjuvant intravesical Gemcitabine is enough active in patients with a solitary, low risk superficial bladder cancer.After diagnostic urethrocystoscopy or bladder sonography, all patients will receive intravesical gemcitabine once a week during 6 weeks. Two weeks after finishing antiblastic therapy, all patients will be submitted to a new cystoscopy, with TUR or cold biopsies of the site of the initial lesion.
