Can We Predict of the Response of High Risk Non Muscle Invasive Bladder Cancer Patients to Intravesical...
Bladder CancerIntravesical 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.
PET/MRI and Biomarkers in Bladder Cancer
Bladder CancerMuscle 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.
Pilot Studie of Lipiodol Demarcation of the Tumour in Bladder Cancer
Bladder CancerRationale: 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.
USPIO-enhanced and Diffusion-weighted MRI for the Detection of Pelvic Lymph Node Metastases
Prostate CancerBladder CancerPreoperative 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.
Use of Multiphoton Microscopy in the Diagnosis of Cancer
Bladder CancerProstate CancerMultiphoton 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.
A Randomized, Comparative Study of Hexvix Fluorescence Cystoscopy and Standard Cystoscopy in Patients...
Bladder CancerThe 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.
Study of the Efficacy of Maintenance Therapy Using Uracil-tegafur (UFT) or Bacille Calmette-Guerin...
Bladder CancerThe 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.
Assessment of safEty, Tolerability, Radiation Dosimetry, and Imaging Properties of 89Zr-labeled...
Bladder CancerThe 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.
The Personal Patient Profile Decision Support for Patients With Bladder Cancer
Bladder CancerThere is a pressing need to develop a personalized, value-based decisional tool for bladder cancer patients undergoing radical cystectomy (bladder removal) and urinary diversion to help them with communication with the physicians, shared decision making, and preparation for disease-management and follow-up care. The proposed intervention, the Personal Patient Profile - Bladder Cancer (P3-BC), will be the first intervention to address these issues. Results of this pilot randomized feasibility study will provide evidence of the feasibility and acceptability of the P3-BC and will guide further refinement of the tool for a larger experimental trial, with potential dissemination of the program via the Internet and hand-held computing devices.
The Difference of Two Year Recurrence Rate According to Anesthetic Method During Transurethral Resection...
Bladder CancerThe 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.
