This phase II trial studies the side effects of avelumab and how well it works in combination with fluorouracil and mitomycin or cisplatin and radiation therapy in treating participants with muscle-invasive bladder cancer. Monoclonal antibodies, such as avelumab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as fluorouracil, mitomycin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. Giving avelumab with chemotherapy and radiotherapy may work better in treating participants with muscle-invasive bladder cancer.

Objectives The primary objective is to demonstrate that in patients undergoing major urologic surgery, Patient Controlled Analgesia (PCA) opioid consumption in the first 24 hours after surgery will be significantly less in patients who have had a single shot rectus sheath block pre-operatively in addition to a post-operative rectus sheath continuous block via surgically placed catheter versus those who only have post-operative rectus sheath continuous block. Secondary outcomes will be opioid requirement intra-operatively, Numerical Rating Scale (NRS) pain scores including maximum pain score in Post Anesthesia Care Unit (PACU) and score at 24 and 48 hours, incidence and severity of nausea, number of vomiting episodes, sedation score, time to first bowel movement, time to first mobilization and duration of hospital stay.
The investigators hypothesize that two pelvic relaxation exercises will be feasible and safe to perform by subjects daily before radiation during the participant's treatment and will decrease variability of sacral slope measurements on daily port films. The investigators will observe trends in the daily variability and change in the sacral slope in each participant to determine if this could decrease variability. The investigators will compare these measurements to a retrospective cohort that did not have the exercises, but did demonstrate variability. Reducing set-up variability (which inadvertently occurs during radiation) is important to improve radiation targets and diminish potential adverse effects. The investigators will query participants for objective and subjective feedback on the exercises and record frequency and duration of the two exercises.
This is a study that will test how an experimental drug (enfortumab vedotin) affects patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra that has spread to nearby tissues or to other areas of the body. This clinical trial will enroll patients who were previously treated with a kind of anticancer drug called an immune checkpoint inhibitor (CPI). Some CPIs have been approved for the treatment of urothelial cancer. This study will test if the cancer shrinks with treatment. This study will also look at the side effects of the drug. A side effect is a response to a drug that is not part of the treatment effect. Patients who sign up for this trial must also fall into one of these categories: - Patients have already received treatment with platinum-containing chemotherapy - Patients have never received platinum-containing treatment and are not eligible for treatment with cisplatin.
Radiotherapy (combined with chemotherapy) is commonly used in the curative treatment of pelvic tumours, such as in cervical, vulvar and anal cancer. In these patients, cure rates are high but may be associated with significant treatment-related toxicities, especially dermatologic, gastrointestinal, genitourinary and hematologic toxicity. Accurate treatment planning and dose delivery is essential for radiotherapy in order to be effective in terms of local tumour control and to reduce radiation-induced side effects. However, accuracy is challenged by tumour and organ motion from fraction to fraction (interfraction movements). At present, radiotherapy treatment planning is typically performed on one planning-CT scan which is performed before the start of the treatment. However, interfraction set up variations and organ motions can lead to differences between the calculated dose distribution on the planning-CT and the radiation dose actually received by the tumour and normal organs (actual given dose). Current photon radiotherapy of the pelvic area is relatively insensitive to these changes and margins from CTV to PTV ensures an adequate dose coverage of the tumour area. Despite newer techniques in photon therapy, like intensity modulated radiotherapy (IMRT), critical organs still receive a substantial amount of dose leading to clinically relevant acute and late side effects. With proton beam therapy, the amount of radiation dose to the organs at risk can be significantly reduced. For proton beam therapy (PBT) however, knowledge of tumour and organ motion will be more important. The major potential advantages of PBT for tumours in the pelvic area in terms of prevention of radiation-induced side effects are challenged by differences in bladder volume, rectal filling and air gaps especially in the small bowel, sigmoid and rectum. Setup errors and organ motion cause geometric displacement of the tumours and normal tissues, which deteriorates the dose gradients from target volume to normal tissue. Furthermore, it can result in changes in tissue densities in the beam path, which can alter the position of the Bragg peaks, in turn leading to distorted dose distributions, usually manifesting as significant local under and/or over dosage. In this study, the investigators want to evaluate the impact of inter and intrafractional tumour and organ motion on photon and proton radiotherapy treatment planning in order to create robust intensity modulated photon- and/or proton treatment plans (IMRT, IMPT) with the final aim to lower treatment related toxicity. Objective: To explore the extent of inter- and intrafraction anatomical changes of the tumour and surrounding normal tissues, throughout the full course of treatment, and to subsequently assess the impact of these changes on the nominal planned dose. This information is required to design robust treatment plans (photon and/or proton) that will ensure optimal local tumour control while reducing toxicity. Study design: Pilot-study (40 patients). Study population: Patients with cervical, vulvar or anal cancer, who are planned for radiotherapy (with or without chemotherapy) with curative intent. Intervention (if applicable): Not applicable. Main study parameters/endpoints: Robustness parameters (homogeneity index; coverage of clinical target volume), dose to organs at risk (OARs), such as the small bowel, rectum, bladder and bone marrow. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: During the radiotherapy treatment course, patients will undergo weekly repeat planning CT scans without contrast agents in order to evaluate the impact of intra and inter-fraction tumour and organ motion. The additional radiation dose of these 5 extra CT's is relatively low (5 x 8 mSv, plus 1 x 22 mSv for the 4D CT scan) in relation to the therapeutic radiation dose (50.4-85 Gy). The risks are therefore negligible and the burden is low.
This study aim to compare the efficacy, safety and quality of life of vinflunine/gemcitabine and carboplatin/gemcitabine in patients with metastatic urothelial cancer and impaired renal function.
This study will test how well Regorafenib controls disease progression in urothelial cancer (cancer occurring in the urinary bladder, ureters, or renal pelvis) following previous therapy with chemotherapy.
The main purpose of this study is to find out the dose of enzalutamide that can be safely given with gemcitabine and cisplatin in patients with advanced bladder cancer. Researchers also want to find out the side effects of these drugs when given together. This study will also help in finding out the effect on tumor of the combination of enzalutamide, gemcitabine and cisplatin.
