Filter by:The purpose of this study is to compare the use of two types of equipment during transurethral resection of bladder tumors (TURBT). The two types of surgical devices are: the monopolar loop electrocautery and the PlasmaKinetic (PK) Button Vaporization Electrode. These two devices do the same task but differ in the way they create electric current when removing cancerous tissue. The investigators hope to examine and compare the uses of these two surgical devices to see if any advantages do exist or whether they actually are similar. The goal of the study is to prove similarity in outcomes between the two techniques and analyze the outcomes resulting from each case.
In this study, the investigators would like to assess how intravesical BCG schedules after immunization of non muscle invasive bladder patients with the recMAGE-A3 protein, together with adjuvant AS15 (recMAGE-A3 + AS15 ASCI), may enhance innate and vaccine-specific T cell responses both systemically and locally in the bladder.
Complications after radical cystectomy for bladder cancer range from 30-40%, many of which are related to bowel function. Patients usually wait to eat until return of bowel function, although there is evidence that after primary intestinal or colonic surgery, patients may take food ad lib immediately, and that this is is associated with lower complication rate and shorter length of stay. The investigators hypothesize that early access to oral enteral nutrition (food at will) after cystectomy and urinary diversion will reduce the complication rate both in-hospital and within 90 days after hospital discharge.
This international, prospective, observational, open-label, pharmaco-epidemiologic study observes cancer patients at risk for chemotherapy-induced febrile neutropenia (FN) who are receiving filgrastim biosimilar (EP2006) for primary or secondary FN prophylaxis to better describe the patient population at risk for FN and treated prophylactically in physician's best clinical judgement with filgrastim biosimilar (EP2006), to describe prophylaxis patterns involving filgrastim biosimilar (EP2006), and to evaluate hematology levels and variability in hematological outcomes, impact on chemotherapy delivery, radiotherapy, surgery, and mortality. Additionally the study aims to identify patient cohorts who are vulnerable to poor response to FN prophylaxis and experience break-through episodes of FN, understand the differences between prophylaxis responders and non-responders, and describe the degree to which prophylaxis of FN is in congruence with guideline recommendations.
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
Intravesical treatment for superficial bladder cancer has been used for the past 4-5 decades. Intravesical chemotherapy is beneficial in terms of recurrence and time to recurrence in grade 1-2 stage Ta tumours, usually non-invasive. Intravesical chemotherapy has negligible effect on disease progression in high-risk superficial bladder cancer—ie, grade 3, stage T1, and carcinoma in situ. However, BCG as induction and maintenance treatment effectively delays progression. Electromotive mitomycin increases tissue uptake compared with that of passive diffusion. Electromotive mitomycin has emerged as an alternative or complementary treatment to BCG. The rationale for combining anticancer drugs is based on the need to increase efficacy and reduce emergence of resistant malignant cells. This approach is not frequently applied to use of intravesical agents for treatment of superficial bladder cancer, for which immunotherapeutic BCG and chemotherapeutic mitomycin seem to be a potentially effective combination. Studies have addressed concurrent use of mitomycin and BCG, and assigned two roles to mitomycin: antitumor action and tissue-scarifying (ie, surface-modifying) effect that enables BCG to attach more efficiently to the urothelium. The investigators therefore aimed to assess whether induction of inflammation by use of BCG before mitomycin treatment makes the bladder mucosa more permeable and thus enables mitomycin to reach the target more easily. This randomised trial to compare the efficacy of sequential BCG and electromotive mitomycin with that of the current standard of BCG alone for patients with high-risk superficial bladder cancer. After transurethral resection and multiple biopsies patients with stage pT1 bladder cancer are randomly assigned to: 81 mg BCG infused over 120 min once a week for 6 weeks; or to 81 mg BCG infused over 120 min once a week for 2 weeks, followed by 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) once a week as one cycle for three cycles (n=107). Complete responders underwent maintenance treatment: those assigned BCG alone had one infusion of 81 mg BCG once a month for 10 months, and those assigned BCG and mitomycin had 40 mg electromotive mitomycin once a month for 2 months, followed by 81 mg BCG once a month as one cycle for three cycles. The primary endpoint was disease-free interval; secondary endpoints were time to progression; overall survival; and disease-specific survival. Analyses were intention to treat.
Taxane-based chemotherapy is currently one of the most commonly used regimen for salvage chemotherapy in advanced urothelial carcinoma. In previously untreated patients, single-agent paclitaxel, administered in a 24-hour infusion, produced an overall response rate of 42%, and single-agent docetaxel as a first-line therapy produced response rates of 31% and 45% in 11 patients with impaired renal function. Of the two taxanes, paclitaxel has been studied more extensively. Intravenous administration of paclitaxel requires the use of solubilizing agents such as Cremophor EL (CrEL) due to its hydrophobicity. CrEL often contributes to hypersensitivity reactions including hypotension or dyspnea with bronchospasm, some of which are major and potentially life-threatening. Minor allergic reactions such as transient rashes and flushing also may occur. Despite pretreatment with corticosteroids and histamine antagonists, minor reactions still occur in 10-44% of all patients, with 1-3% of patients experiencing potentially fatal reactions. CrEL may also act as a potential cofactor for the development of peripheral neuropathy. In addition, special infusion sets must be used clinically when administering CrEL-based paclitaxel. Genexol-PM (Samyang Co., Seoul, Korea), a form of paclitaxel formulated with sterile, lyophilized polymeric micells that allow intravenous delivery of paclitaxel without CrEL. The polymeric micelle formulation is composed of hundreds of low molecular weight, nontoxic, and biodegradable amphiphilic diblock copolymers which include monomethoxy poly(ethylene glycol)-block-poly(D,L-lactide), and has a great potential in terms of water solubility, in vivo stability, and the nanoscopic size (a diameter of 20-50 nm) of the micellar structure. A phase I study established that Genexol-PM administered at 390 mg/m2 intravenously for 3 h every 3 weeks was the maximum tolerable dose (MTD) in humans. Dose-limiting toxicities were neuropathy, myalgia, and neutropenia. No hypersensitivity reactions were observed in any patients despite the absence of antiallergic premedication. The recommended dosage for phase II studies was 300 mg/m2. Based on the promising results of taxane-based chemotherapy and the absence of standard second-line chemotherapy regimen for advanced urothelial cancer, the investigators designed phase II study to explore the efficacy and safety of Genexol-PM in advanced urothelial patients, who previously treated with gemcitabine plus platinum as adjuvant chemotherapy or 1st line therapy for metastatic diseases.
When the bladder is removed for bladder cancer, pelvic lymph nodes (LN) are also removed. While the anatomic extent of this LN dissection is critical, the investigators often use the number of LN removed as a measure of the extent, which in turn is essential for determining the patient's further treatment and prognosis. The LN count, however, is also dependent on the pathologist's processing of the LN tissue, and the standards for this processing are poorly defined. The goal of this study is to establish a standardized method for processing and analyzing lymph node specimens. The investigators hypothesize that if an organic solvent is used to remove excess fat from the lymph nodes that the investigators will discover more clinically significant nodes in a more reproducible fashion when compared to the current method.
The purpose of this study is to evaluate the safety of MGA271 when given by intravenous (IV) infusion to patients with refractory cancer. The study will also evaluate how long MGA271 stays in the blood and how long it takes for it to leave the body, what is the highest dose that can safely be given, and whether it may have an effect on tumors.
The purpose of this study is to evaluate the safety and pharmacokinetics (PK) of intravesical instillation of EO9 in patients with non-muscle invasive bladder cancer (NMIBC).
