Comparison of Safety and Efficacy of Detaenial Sigmoid Neobladder and Ileal Neobladder

Bladder cancer is a common malignant tumor of the urinary system, radical resection plus urinary diversion is the first choice of treatment for muscle invasive bladder cancer. Urinary diversion of surgical options related to patient' survival and quality of life. In 1988, Hautmann firstly reported an orthotopic urinary diversion method: Hautmann neobladder. As the urine can be controlled from the original urethra, the patient's quality of life has been greatly improved, so the new bladder surgery gradually accepted and welcomed by urologists and patients. However, in order to achieve low-pressure and large-volume storage capacity of the urine reservoir, the 40-70cm long interception of terminal ileum need to be detubularized. Only after split, folded, re-stitched and a series of treatment, the intestinal can be used. Such complicated procedures make so many urologists give it up. In addition, the interception of the long ileum may lead to reduced absorption of vitamin B12 which caused anemia, metabolic acidosis, intestinal dysfunction. Not only that, as time goes by, this kind of neobladder will be unlimited expansion and resulting in a serious increase in residual urine volume, hydronephrosis, or even the occurrence of neobladder spontaneous rupture. In 2000, professor Chunxiao Liu invented "detaenial sigmoid neobladder", this surgical method overset the traditional intestinal detubularization approach, which detached the serosal layer with smooth muscle from the bowel without split it. This kind of neobladder is easier to construct and have less impact on intestinal function. So far, it has been implemented for more than 600 cases in Zhujiang hospital, the age of patients range from 9 months (bladder rhabdomyosarcoma) to 84 years old. So far as now, no multicenter prospective clinical study on orthotopic urinary diversion has been performed worldwide, neither the head-to-head studies on detaenial sigmoid neobladder and ileal neobladder. Our project is going to perform a multicenter randomized controlled trial for these two neobladder methods and look forward to assess the safety and efficacy of these two procedures which provide an objective basis for the patients undergoing orthotopic urinary diversion in the future.

Bintrafusp Alfa (M7824) and NHS-IL12 (M9241) Alone and in Combination With Stereotactic Body Radiation Therapy (SBRT) in Adults With Metastatic Non-Prostate Genitourinary Malignancies

Background: Genitourinary cancers are some of the most common types of cancer. They are lethal when they spread. The drug M7824 blocks the paths that cancer cells use to stop the immune system from fighting cancer. The drug M9241 triggers the immune system to fight cancer. Researchers want to learn if these drugs can help fight these cancers when given with and without Stereotactic Body Radiation Therapy (SBRT) radiation. Objective: To learn if M7824 and M9241, with or without SBRT, can help the immune system to fight cancer better. Eligibility: People 18 and older with cancer that started in the bladder, kidneys, or other genitourinary organs (but not the prostate) and has spread to other parts of the body. Design: Participants will be screened with: medical history physical exam ability to do their normal activities blood tests urine tests electrocardiogram body scans. Participants will give a tumor sample or have a tumor biopsy. Screening tests will be repeated during the study. Participants will get M9241. It is injected under the skin every 4 weeks. They will also get M7824 through an intravenous (IV) infusion every 2 weeks. For this, a small plastic tube is put into a vein in the arm. They will get these drugs in 28-day cycles until they leave the study. They may have SBRT. Participants will give tissue and saliva samples. Participants will have a follow-up visit 30 days after treatment ends. Then they will get phone calls or emails every 12 weeks indefinitely.
