Filter by:This is a single-arm, multicenter study to evaluate the efficacy and safety of HX008 injection in patients with BCG-unresponsive non-muscle invasive bladder cancer.
A multi-center, randomized, open-label, parallel-controlled Phase Ⅲ clinical trial to evaluate the clinical safety and efficacy of APL-1202 as a single-agent oral treatment versus intravesical instillation of Epirubicin hydrochloride in naïve intermediate-risk non-muscle invasive bladder cancer (NMIBC) patients
This is a phase II study to determine the safety and efficacy of tislelizumab when given in combination with nab-paclitaxel as treatment for patients with high-risk non-muscle-invasive bladder cancer (HR NMIBC) which is not completely resectable. Patients will receive treatment with tislelizumab in combination with nab-paclitaxel every 3 weeks for 4 treatment cycles over 12 weeks followed by transurethral resection biopsy.
This is a phase II study to determine the safety and efficacy of tislelizumab when given in combination with nab-paclitaxel as perioperative treatment in patients with muscle-invasive bladder cancer (MIBC) prior to cystectomy or complete TURBT. Patients will receive treatment with tislelizumab in combination with nab-paclitaxel every 3 weeks for 3 treatment cycles over 9 weeks followed by standard radical cystectomy or complete TURBT.
Non-muscle-invasive bladder cancer (NMIBC) has a high rate of recurrence (60 to 70%) and progression (20 to 30%) to muscle-invasive bladder cancer (MIBC). The local immunotherapy (intra-vesical Bacillus Calmette-Guerin (BCG) following transurethral resection of the bladder tumor (TURBT)) reduces significantly the risk of recurrence and progression as compared to observation or to intra-vesical chemotherapy. Systemic immunotherapy with programmed death ligand-1 (PD-L1) or Programmed cell Death 1 (PD1) inhibitors has shown major efficacy in the treatment of patients with advanced/metastatic urothelial carcinoma who have progressed on platinum-based regimens of chemotherapy, or even in front line setting. In the field of NMIBC, immunotherapy using PD-L1 or PD1 inhibitors is under investigation but the frequency of PD-L1 expression has rarely been precisely described in the different subtypes. The aim of this retrospective study is to investigate the expression of PD-L1 by different types of NMIBC. The secondary objective is to characterize the immune contexture of NMIBC.
Evaluate the impact of 18F-FDG-PET-CT on the staging of patients with muscle invasive bladder cancer. Based on the results of 2 18F-FDG-PET-CT's patients are stratified in non-metastatic, oligometastatic and polymetastatic bladder cancer patients and the treatment is adapted accordingly to improve overall survival.
This research study will assess what doses of Sacituzumab Govitecan and Enfortumab Vedotin can be safely combined in the treatment of metastatic urothelial carcinoma (mUC). The names of the study drugs in this investigational combination are: - Enfortumab Vedotin - Sacituzumab Govitecan
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.
To facilitate the follow-up of urothelial tumors and also make them more tolerable and less invasive for patients, there is a minimally invasive and easy to perform examination which is urinary cytology on 3 samples. This test is extremely specific, over 90% chance of cancer if it is positive and is performed by expert cytopathologists, but it is burdened by a very low sensitivity, which is especially acute in the case of low grade tumors. This makes it an extremely useful test in case of positivity, but of little use if negative or doubtful, not being able to consider it reliable. To overcome this problem, our study aims to bring an approach based on a physical principle, that is spectroscopy, which is fast non-invasive and does not require the use of additional substances or contrast media in the diagnosis of urothelial neoplasms in samples of urine. In our experience, multimodal optical fiber spectroscopy has proved extremely valid in discriminating healthy urothelial tissue from tumor ex vivo, as well as providing important information on the degree of urothelial neoplasia, with accuracy rates higher than 80%, for which developed the idea of a technique based on multimodal spectroscopy. If our method proves valid, it could improve the follow up and management of patients with urothelial cancer, being able to support normal cytology and provide further support to the cytopathologist, as well as simplify the diagnosis.
INTRODUCTION Bladder tumor is the second most common neoplasm in the genitourinary tract. Most cases of ex novo diagnosis of bladder cancers are present as non-invasive muscle tumors, which are treatable through endourological procedures. The current standard is based on conventional transurethral resection of bladder tumor, although high rates of recurrence have been reported following resection of the primary tumor. Given the importance of a correct initial diagnosis in these cases, en bloc transurethral resection has developed over the past 2 decades. This technique was born, according to the literature, with 3 main objectives: to improve the quality of the surgical piece for its anatomopathological reading, reduce the rate of postoperative complications and reduce the rate of relapses in the surgical bed. This technique is used as a common practice of tumor resection in other centers and has been shown in multiple publications that it does not increase surgical risk or negatively affect cancer results. OBJECTIVE The objective of our study is to compare feasibility, perioperative complication rate, accuracy of staging and recurrence/progression rates when performing en bloc resection by means of different energies: monopolar, bipolar and laser energy. MATERIAL AND METHODS Between April 2018 and June 2021, a prospective randomized study will be conducted including patients undergoing a transurethral resection of initial or recurrent bladder tumor, either unifocal or multifocal. Patients with tumors less than 3 cm and with less than 3 tumors shall be included if multiple. Patients with more than 3 tumors or tumors over 3cm, those with evidence of invasive muscle tumor(cT2) or those with evidence of remote metastasis, whether lymphatic or organic, will be excluded. Patients will be randomized into two groups: - Group 1 (test): en bloc resection (n-180). It will be divided into 3 subgroups according to the energy used (monopolar, bipolar, laser energy). - Group 2 (control): Conventional transurethral resection (n-120). It will be divided into 2 subgroups depending on the energy used (monopolar or bipolar). A fact sheet will be given to the patient about the study and the signature of the informed consent will be requested in order to be included. The patient will be free to leave the study at any time without having to provide any justification and without affecting the treatment, intervention and follow-up that must be carried out. The processing and storage of samples will be carried out in the pathological anatomy laboratory, according to standard clinical practice. Patients will be monitored according to the usual clinical practice protocol (minimum 5-year follow-up), included in the non-muscle invasive bladder tumor protocols of the Puigvert Foundation.
