Active clinical trials for "Urinary Bladder Neoplasms"

Intravesical BCG is the mainstay adjuvant management of high risk NMIBC. Adequacy of immune system stimulation is the determinant factor for patient response to BCG. Immunological markers for BCG-response could be helpful for urologists especially in the era of BCG shortage. Objectives: To assess the predictive performance of different immunological markers on BCG-response in high risk NMIBC BCG-naïve patients.

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 main objective of the study is to compare the 1-year recurrence rate of Hexvix assisted Transuretheral Resection of the Bladder (TURB) to standard white light TURB in patients with suspicion of non-invasive bladder cancer. The hypothesis is to test whether the 1-year recurrence rate is different with Hexvix assisted TURB compared to standard white light TURB.

Preoperative detection of lymph node metastases in patients with prostate or bladder cancer is crucial for selection of the appropriate treatment strategy (surgery, androgen deprivation with/or without radiation therapy or chemotherapy) and thus for patient prognosis. Until now CT or MRI have been the modalities of choice for preoperative staging procedures. However, current morphological assessment of lymph nodes based on size and shape is unable to detect smaller metastases or liable to give false positive results on lymph nodes with reactive hyperplasia. We hypothesize that USPIO-enhanced MRI combined with DW-MRI will be able to detect pelvic lymph node metastases preoperatively with high sensitivity and specificity.

Rationale: Bladder tumours are often not visible on X-ray based image-modalities during planning and treatment of Radiotherapy. Purpose: To determine if a single contrast (Lipiodol) demarcation of the bladder tumour before treatment is feasible and visible on multiple X-ray based image-modalities during Radiotherapy.

Multiphoton microscopy (MPM) has been shown to be able to image tissue at a cellular level. Our project will initially evaluated the ability of MPM imaging to distinguish normal bladder urothelium from atypical and malignant urothelium in the ex vivo setting. After development of sufficient criteria, we plan to develop an endoscopic bladder probe that will provide a non-invasive means to image the interior of the bladder at the cellular level, which would provide direct evidence of the presence of tumor without a biopsy. After exhibiting usefulness of MPM imaging for bladder cancer, we will look at other organs beginning with the colon.

The purpose of this prospective randomized controlled study is to prove the non-inferiority of UFT maintenance therapy to BCG maintenance therapy for preventing recurrences of superficial bladder cancer.

The investigators compare the recurrence rate difference between two years after transurethral resection of the bladder tumor according to the method of anesthesia. Anesthetic methods are general anesthesia and spinal anesthesia. Assessment of recurrence is assessed by bladder endoscopy, CT, and pathological examination of surgical specimens.

This clinical study is designed to evaluate the diagnostic performance of VisioCyt test, which would improve the early diagnosis of bladder cancer in order to optimize the management of individual patients as part of a cancer diagnostic monitoring. The diagnostic method of VisioCyt® device is based on the analysis by transmission and fluorescence, of urinary cytology slides prepared according to the protocol VisioCyt.

The purpose of this study is to evaluate the use of 89Zr-labeled girentuximab (89Zr-TLX250) as a novel, carbonic anhydrase IX (CAIX) targeted PET/CT radiopharmaceutical for the imaging of Non-muscle-invasive bladder cancer (NMIBC) patients.
