Active clinical trials for "Carcinoma, Transitional Cell"

Two out of three tumours in the upper urinary tract are located in the renal pelvis. Muscle-invasive urothelial carcinoma is probably more common among tumours in the upper urinary tract compared to tumours in the urinary bladder. Thus, muscle-invasive tumours represent approximately 45 % of renal pelvic tumours compared to 25 % of tumours within the urinary bladder. As in the bladder, lymph node metastases are rare in non-muscle invasive disease. Information regarding indications, extent and possible curative potential is currently lacking for lymphadenectomy in conjunction with nephroureterectomy for urothelial carcinoma in the upper urinary tract (UUTUC). There are, however, retrospective series with survival data for patients with lymph node metastasis that report long term survival after surgery as monotherapy [4] with similar survival proportions as in bladder cancer with lymph node metastases after radical cystectomy. A retrospective study from Tokyo was expanded to the only available prospective study, where 68 patients with UUTUC were submitted to template-based lymphadenectomy. Another retrospective study by the same Japanese group, showed that 5-year cancer-specific and recurrence-free survival was significantly higher in the complete lymphadenectomy group than in the incomplete lymphadenectomy or without lymphadenectomy groups. Tanaka N et al. reported recurrence rate after nephroureterectomy without lymphadenectomy at 1 and 3 years were 18.9 and 29.8 %, respectively.

Upper tract urothelial cancer (UTUC) is cancer in the lining of the kidney or ureter (the tube that drains the kidney). This type of cancer is rare and as a result, there are only a few studies that have looked at it. Standard of care for UTUC would be surgery followed by chemotherapy (adjuvant chemotherapy). However, we know from studies that have looked at cancer of the lining of the bladder, which is a similar cancer in many ways, that treating people with chemotherapy before surgery (neoadjuvant chemotherapy) can lead to longer survival compared to the standard of care. There are no studies to show this in UTUC. Neoadjuvant chemotherapy is thought to help improve survival by treating any cancer that may have spread from the original tumour but that is not visible yet on scans. This study would be the first clinical trial in Canada to evaluate the use of chemotherapy before surgery in this disease setting. Since UTUC is rare, the purpose of this study is to determine if it is possible to enrol enough patients to a trial looking at the use of chemotherapy before surgery.

This is a non-randomized two arm open-label phase 2 pilot study in adult subjects with locally advanced or metastatic urothelial cancer. The study will investigate an alternative administration schedule of EV given as monotherapy and in combination with pembrolizumab.

The aim of this study is to evaluate the effectiveness and safety of intravesical gemcitabine instillation during operation to prevent intravesical recurrence after radical nephroureterectomy in upper urinary tract urothelial carcinoma.

This pilot study aims to investigate the PSMA expression in the biopsy material of advanced soft tissue sarcomas and advanced urothelial cell carcinomas, and in case of high PSMA expression (as defined by previous literature), to investigate whether this correlates with high tracer uptake on PSMA-targeted PET. This way, (a subset of) patients can be selected that could benefit from radionuclide targeted therapy in the future.

The SeARCH-trial assess the clinical impact of a molecular urine test as a 'urine-first' strategy in the diagnostic workup of patients presenting with microscopic hematuria.

Urine cytology can be collected with spontaneous urine or by washing the bladder. It is commonly accepted among urologist that instrumental bladder washing is the method of choice. There are, however, no solid recommendations regarding the method to collect the urine for bladder wash cytology during cystoscopy. There are mainly two possibilities: 1) the use of an intermittent bladder catheter after the removal of the cystoscope or 2) bladder lavage through working channel of the flexible cystoscope itself. The first choice may increase the number of collected cells because of the larger caliber of the catheter compared to the working channel and thus the better efficacy of bladder wash. However, this method is certainly more invasive and possibly more expensive. To the best of our knowledge and according to available literature, none of both collection method can be defined as gold standard. The aim of the study is to show that use of flexible cystoscope brings the same results in terms of quality of the urine collection for analysis as the use of intermittent bladder catheter and is less unpleasant for the patient. If our study confirms the non-inferiority of "direct" collection through the cystoscope, this will allow the establishment of recommendations in this sense in order to simplify the procedure and reduce as much as possible the manipulations within the urogenital tract.

The purpose of this study is to understand the metabolism of cancers involving the kidney, including renal cell carcinomas and urothelial cell carcinomas, and how kidney cancers use different types of fuel to support tumor growth. This study uses specially labeled nutrient tracers of compounds normally found circulating in the blood. The nutrients (glucose, fructose, glutamine, acetate, and lactate) are also found in common foods. A nutrient tracer will be given to the participants through an intravenous (IV) catheter during surgery or biopsy, and blood will be collected every 30 minutes during the infusion to monitor safety parameters and the nutrient tracers. The investigators will collect a tissue sample after the completion of surgery. Participants not having an infusion will have their tissue collected after surgery or biopsy. Participation in this study will not change patient care. All patients will receive standard of care treatment as determined by their doctors.

The aim of this study is to explore feasibility of Upper Tract Urothelial Carcinoma (UTUC) treatments based in real world data in various European countries. The study will allow to gain insight in the true proportion of patients that fit to receive complete cisplatin-based neo-adjuvant or adjuvant chemotherapy, and the proportion and clinical outcome of patients with poor prognostic factors (PS and renal function) who receive only standard treatment (Radical nephroureterectomy (RNU)). This comparison will be made using a uniform diagnostic and treatment protocol.

This phase III trial studies olaparib or cediranib maleate and olaparib to see how well they work compared with standard platinum-based chemotherapy in treating patients with platinum-sensitive ovarian, fallopian tube, or primary peritoneal cancer that has come back. Olaparib and cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cediranib maleate may stop the growth of ovarian, fallopian tube, or primary peritoneal cancer by blocking the growth of new blood vessels necessary for tumor growth. Drugs used in chemotherapy, such as carboplatin, paclitaxel, gemcitabine hydrochloride, and pegylated liposomal doxorubicin 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. It is not yet known whether olaparib or cediranib maleate and olaparib is more effective than standard platinum-based chemotherapy in treating patients with platinum-sensitive ovarian, fallopian tube, or primary peritoneal cancer.
