Filter by:Bladder cancer (BC) is a heterogeneous malignancy with dismal outcome.Despite treatment, the 5-year overall survival rates for MIBC are <50%, with many patients unresponsive or inapt, necessitating biomarkers to select those most likely to respond or fit for treatment
Non-muscle invasive bladder cancers (NMIBC) compose about 80% of bladder tumors. the stranded treatment of these tumors is TURBT. en bloc resection of NMIBC yields better mascularis propria with better oncological outcomes
This study is a prospective randomised controlled study of urinary bladder cancer patients presented to urology unit at National Cancer Institute; Cairo University.
The primary objective of this study, DELFI-L101, is to train and test classifiers for lung cancer detection using the DELFI assay and other biomarker and clinical features.
Bladder cancer (BC) is one of the most common cancers worldwide and the most successful example of vaccine in cancer treatment, representing an efficient model for studying the importance of systemic and local immune mechanisms. Despite being the standard of treatment for the last 40 years, the exact mode of action of immunotherapy with the bacillus Calmette-Guérin (BCG) is still poorly defined. In a mechanistic study, the investigators intend to prospectively investigate immunological signatures, including immune-checkpoints, pre and post-treatment in patients with BC, and correlate the cytokines of the immune by-product and BCG administration pathway to understand the independent contributions of BCG priming (prior exposure to BCG) and crosstalk immunotherapy between tumor profiles and immune response of the patient. The proposed research strategy is justified by the need to identify subsets of patients who better respond to an intervention, or to predict why new immunotherapies and drugs may be successful or failed in clinical trials.
A Multicenter, Non-randomized, Uncontrolled, Open-label Phase I/II study to Observe the Safety and Preliminary Efficacy of Catumaxomab in Patients with Non-Muscle-Invasive Bladder Cancer who have Failed or are Intolerant to Bacillus Calmette-Guerin (BCG) Vaccine
Clinically node positive (cN+) bladder cancer carries a poor prognosis, especially in patients who are unable to receive or fail to respond to neoadjuvant chemotherapy. Immune checkpoint inhibitor (ICI) therapy is FDA-approved in advanced bladder cancer for patients unable to receive or failing to respond to platinum-based chemotherapy. The present study seeks to determine if next-generation radiation therapy (personalized ultrafractionated stereotactic ablative radiotherapy, or PULSAR) is feasible and effective in patients receiving ICI for bulky cN+ bladder cancer.
Our multicenter observational study is a non-profit prospective study. The study was born from the Amplitude Project, which comprise the SOD of Minimally Invasive Robotic Urological Surgery and Renal Transplants of AOU Careggi with the University of Florence, as well as with the National Research Council (CNR) and the University of Milan Bicocca (UNIMIB) The study consists of a phase of enrollment of patients who will be admitted to the SOD of Mini Invasive Robotic Urological Surgery and Renal Transplantation of AOU Careggi. Enrollment in the study does not alter normal clinical practice and does not involve additional risks for patients. Patients will have to meet the inclusion and exclusion criteria of the study and will be enrolled sequentially, until the established sample size is reached. Patients undergoing surgery for the removal of bladder neoplasm, be it endoscopic or surgical with radical intent (cystectomy), will be taken a fragment of tumor bladder tissue, on which histopathological analysis will be performed. In patients undergoing radical cystectomy only, a fragment of healthy urothelial tissue, free from neoplasia, will also be removed. The samples will be performed in patients under general and / or spinal anesthesia in case of TURB, thus not causing pain or discomfort to the patient, or ex-vivo on the operative piece in case of radical cystectomy, without causing further damage or pain to the patient. From these samples, specially stored in solutions that keep their characteristics unaltered, a 3D culture model (organoid) will be obtained both from cells obtained from bladder cancer and from healthy tissue on which biomolecular, metabolomic and spectroscopic characterization studies will be tested and carried out. with a view to staging and grading bladder neoplasia.
Purpose To investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patient with high-risk non-muscle-invasive bladder cancer. Methods Patients diagnosed with primary high risk non-muscle-invasive bladder cancer were included to the study. The patients were randomly seperated into 3 groups acoording to Re-TUR timing. In group 1,2, and 3, the time interval between initial and re-TUR were 14-28 days, 29-42 days, and 43-56 days respectively. Kaplan -meier plots were used to estimate differences in recurrence free survival (RFS) and progression free survival (PFS) rates. Cox regression analysis was used to assess the effect of time from initial TUR to re-TUR on oncological outcomes. Results A total of 109 patients with high risk non-muscle-invasive bladder cancer were randomly divided into 3 groups. Twenty patients in group 1 (14-28 days), 22 patients in group 2 (29-42 days), and 29 patients in group 3 (43-56 days) completed the study. The mean follow-up was 20 ± 8.9 months. Kaplan-Meier plots showed no differences in RFS and PFS rates between the three groups. Cox regression analysis demonstrated that only tumor number was found to be a prognostic factor on RFS rates. Conclusion Our prospective study demonstrated that time laps from initial TUR to re-TUR did not significantly affect on RFS and PFS rates.
