Filter by:Extended pelvic lymph node dissection in bladder carcinoma provides staging and, in selected patients, a survival benefit. Recent studies showed the therapeutic benefit of retroperitoneal lymph node dissection (RPLND) in advanced stage of upper tract urothelial carcinoma (UTUC). Also laparoscopic extended RPLND is still a technical challenge in urology, considering the high rate of severe complications and difficulties in manipulation. In Renji Hospital, laparoscopic extended RPLND at time of nephroureterectomy was performed via an extraperitoneal approach, avoiding interference with abdominal organs and achieving better exposure.The aim of the present study was to determine the safety and feasibility of performing an extraperitoneal laparoscopic extended RPLND at the time of radical nephroureterectomy (RNU) for UTUC in a prospectively collected cohort of patients.
Upon successful screening and registration, enrollment to durvalumab monotherapy (cohort 1) will begin. If DLT criteria outlined in the protocol are exceeded with durvalumab monotherapy (cohort 1), the study will close. Provided the safety of durvalumab monotherapy is established, enrollment to combination regimen cohorts will proceed. Cohorts will simultaneously enroll in parallel to each other with patients assigned to cohorts based on patient slot availability and study site choice of radiation arm participation. Patient assignment to future phase 1 arms would proceed similarly. Within BCG-containing cohorts, treatment will begin at full-dose BCG. If DLT criteria outlined in Section 5.1.4 are exceeded with full-dose BCG, a one level dose reduction of BCG will be implemented. If DLT criteria outlined in Section 5.1.4 are exceeded with reduced-dose BCG, the BCG-containing cohort will not proceed to Phase 2 of the study. Similarly, if DLT criteria outlined in Section 5.1.4 are exceeded within non-BCG containing cohorts, the non-BCG containing cohort will not proceed to phase 2 of the study. Due to the prolonged half-life of antibody therapies, no dose adjustments are planned for durvalumab in any of the cohorts.
The objective is to show non-inferiority of overall survival between four cycles and six cycles of first-line cisplatin based chemotherapy to determine the optimal duration of chemotherapy in patients with advanced urothelial carcinoma.
This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.
Continous evaluation of clinical and oncologic outcome of robot-assisted cystectomy with intracorporeal reconstruction of urinary diversion. Patient Data is entered in an anonymized registry for analyzation.
This clinical trial is designed to evaluate the role of lymph node dissection in the prevention of recurrence and metastasis after radical nephroureterectomy for high-risk primary upper tract urothelial carcinoma (UTUC) patients.
The investigators evaluated the efficacy of a single early intravesical instillation of doxetaxel in the prevention of bladder recurrence after nephroureterectomy or distal ureterectomy for upper urinary tract urothelial carcinoma (UUT-UC).
This study aims to verify superiority of pemetrexed maintenance to observation for patient without disease progression after 1 st line cisplatin-based chemotherapy.
This is a Phase I/II and multicenter study designed to evaluate the efficacy and safety of 4SCAR-T cells in participants with locally advanced or metastatic urothelial bladder cancer (UBC) who have no further treatment available.
This is a multi-center, open-label, phase 2 study evaluating the humanized anti-PD-1 antibody JS001, as a monotherapy in patients with locally advanced or metastatic bladder urothelial carcinoma who have failed in routine systemic treatment.
