Filter by: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.
In this prospective randomized controlled study, the effects of obturator nerve block (ONB) on obturator reflex, incomplete resection, perforation, tumor recurrence and progression, presence of muscle tissue in the specimen, need for second transurethral resection of bladder tumours (TURBT) and postoperative complications were investigated in patients who underwent TURBT for intermediate and high risk lateral wall non-muscle invasive bladder tumours (NMIBC).
This study is a prospective randomised controlled study of urinary bladder cancer patients presented to urology unit at National Cancer Institute; Cairo University.
Phase I exploratory, open-label, single arm, multicenter study to assess safety, tolerability and antitumor activity of ONCOFID-P-B™ therapy in adult patients with histologically confirmed diagnosis of bladder carcinoma in situ (CIS), who were unresponsive or intolerant to Bacillus Calmette-Guérin (BCG)-therapy. Patients are initially treated with 12 weekly intravesical instillations of ONCOFID-P-B™ (intensive treatment phase). Patients who achieve a complete response (CR) after the 12 weekly instillations entered the maintenance phase of the study, during which ONCOFID-P-B™ is furtherly administered once a month for 12 months.
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.
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.
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.
The aim of the study is to investigate the oncological outcomes of obturator nerve blockade in patients with lateral wall localized non-muscle invasive bladder cancer
The purpose of the study is to assess, at control visit (V8), the ablative activity of intravesical administration of Oncofid-P-B on a papillary marker tumor on patients suffering from multiple primary and recurrent Ta G1-G2 papillary cancer of the bladder after 6 weeks of weekly study drug administration, through number and percentage of patients with Complete Response.
Non-muscle invasive bladder tumor is a condition that can recur with a risk of progression to an infiltrating tumor of the muscle. Regular follow-up is therefore essential to detect any recurrence or progression of the disease as early as possible. Currently, the monitoring of this type of tumor is done by cystoscopy (examination that allows visualization of the bladder wall) associated with urinary cytology (analysis of urine to detect an abnormality). These examinations have their limits, they may not detect certain types of tumors or may be painful. To reduce the number of cystoscopies and replace urinary cytology, several urinary markers have been developed in recent years. This is the case of the Xpert® Bladder Cancer Monitor test, which is a non-invasive, in vitro diagnostic urine test dedicated to the monitoring of patients with bladder cancer. The purpose of this study is to evaluate the diagnostic performance of the Xpert® Bladder Cancer Monitor test for the detection of bladder tumor recurrence, compared to reference tests.
