Filter by:This study will evaluate the effect of preoperative oral immunonutrition on postoperative complications in patients undergoing radical cystectomy for bladder cancer. Patients receiving preoperative immunonutrition will be compared to controls receiving a standard high-calorie, high-protein oral nutritional supplement.
The main objective of this study is to evaluate the induction of Th1 anti-TERT responses by treatments in patients with bladder tumor.
This Phase 3, single-arm, multicenter study will evaluate the efficacy and safety of UGN-103, a novel formulation of UGN-102, instilled in the urinary bladder of patients with low-grade non-muscle invasive bladder cancer (LG-NMIBC).
The purpose of this study is to determine the efficacy and safety of Hyperthermic Intravesical Chemotherapy (HIVEC) with Gemcitabine (GEM) after Transurethral Resection of Bladder Tumors (TURBT) in the treatment of medium or high-risk group Non-Muscle-Invasive Bladder Cancer (NMIBC).
Bladder cancer (BC) is the 10th most commonly diagnosed cancer worldwide and the second most common cancer among Egyptian males. The mainstay of treatment of muscle-invasive BC( MIBC) is neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) or bladder preservation(BP) using maximal transurethral resection of the bladder tumor followed by chemoradiation. The rationale to use NAC before RC or BP is to eradicate micro-metastasis and to downstage the primary tumor. The 5-year cancer-specific survival for responders to NAC is 90%, in contrast to 30-40% for those not obtaining an objective response. Drawbacks of NAC are disappointing delay of surgery in non-responders and the potential toxicity. So, predictors of response to NAC are necessary to identify patients who may achieve pathologic complete response and will benefit from BP, and the others who may not respond to NAC and spare them NAC toxicity and RC delay. Tumor microenvironment (TME), including neutrophil extracellular traps (NETs), and CD8+ T lymphocytes is a promising predictor of response to NAC in MIBC. NETs are reticulated DNA structures decorated with various protein substances (e.g., histones, myeloperoxidase, neutrophil elastase).NETs are involved in tumor growth, metastasis, and treatment resistance. Moreover, NETs can inhibit T cell responses, thereby promoting tumor growth. On the other hand, immune cells that are present in the TME play a major role in slowing down tumor progression. CD8+T lymphocytes play a central role in immune-mediated control of cancer . Also, they have been found to be a prognostic tool for advanced BC.
This trial plans to enroll 190 eligible patients and randomize them into two groups with a 1:1 ratio, with 95 patients in each group. The experimental group will receive immediate cryoablation therapy at the resection site after TUR, while the control group will only undergo TUR and receive conventional BCG instillation therapy postoperatively. Both groups of subjects will undergo Re-TURBT or cystoscopy 10-12 weeks after surgery to compare the tumor-free residual rates and adverse events between the two groups.
We aim to investigate a possible role for radiotherapy in good prognosis bladder cancer patients has been identified as a possible alternative to cystectomy, especially for patients non-eligible for surgery but has yet to be fully explored.
The goal of this clinical trial is to determine if a partial cystectomy with extended pelvic lymph node removal will be effective at treating Muscle-Invasive Bladder Cancer instead of a complete cystectomy with extended pelvic lymph node removal. This clinical trial aims to determine the safety and oncologic efficacy of the intervention, and to examine patient-reported quality of life outcomes in participants. Participants will receive the standard pre-surgery treatment for approximately 4 to 6 weeks. After the pre-surgery treatment is completed, participants will undergo a partial cystectomy with extended pelvic lymph node dissection. After surgery, participants will receive adjuvant systemic therapy.
This is a prospective, single-arm study to evaluate the feasibility and safety of performing transurethral en-bloc resection of bladder tumours using the Zenith robotic system.
This phase II trial tests how well the combination of futibatinib and durvalumab given before cystectomy works in treating patients with muscle-invasive bladder cancer (MIBC) who are ineligible for cisplatin-based therapy. Cisplatin-based therapy is the standard of care for patients with MIBC. However, many patients cannot receive standard therapy due to poor renal function, peripheral neuropathy, poor functional status, or clinically significant heart failure. Futibatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Radical cystectomy is a surgery to remove all of the bladder as well as nearby tissues and organs. Giving futibatinib in combination with durvalumab before surgery may be an effective treatment option for patients with MIBC who are ineligible for cisplatin-based therapy.
