Filter by:This study will test an experimental drug (enfortumab vedotin) alone and with different combinations of anticancer therapies. Pembrolizumab is an immune checkpoint inhibitor (CPI) that is used to treat patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra. Some parts of the study will look at locally advanced or metastatic urothelial cancer (la/mUC), which means the cancer has spread to nearby tissues or to other areas of the body. Other parts of the study will look at muscle-invasive bladder cancer (MIBC), which is cancer at an earlier stage that has spread into the muscle wall of the bladder. This study will look at the side effects of enfortumab vedotin alone and with other anticancer therapies. A side effect is a response to a drug that is not part of the treatment effect. This study will also test if the cancer shrinks with the different treatment combinations.
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 phase II trial studies the side effects of atezolizumab with or without eribulin mesylate and how well they work in treating patients with urothelial cancer that has come back (recurrent), spread to nearby tissues or lymph nodes (locally advanced), or spread from where it first started (primary site) to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as eribulin mesylate, 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. Giving atezolizumab and eribulin mesylate may work better at treating urothelial cancer compared to atezolizumab alone.
Cancer-related pain represents a major challenge for both clinicians and patients. This pain can be associated directly with the cancer or with certain treatments administered to the patient. 52.1% of cancer patients suffer from pain and that 62.6% are not satisfied with the current pain treatment. Pain prevalence is high in developing countries due to late diagnosis and major impediments to opioid access
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.
The present register has been designed to confirm the hypothesis that while using high quality Intensity Modulated Radiation Techniques (IMRT) and a reduced external beam stereotactic boost component it would be possible to maintain the late severe toxicity rates under the 5 % level in situations where brachytherapy could not be proposed as a boost.
The present single-center prospective exploratory study, conducted at Heidelberg University Hospital, assesses the feasibility of introducing a concept for additional patient care based on a mobile application for patients undergoing radiotherapy. Patients presenting themselves for the irradiation of thoracic or pelvic tumors will be surveyed regarding general performance, treatment-related Quality of Life (QoL) and symptoms and their need to personally consult a physician on a treatment-daily basis by means of a mobile application. The primary endpoint of feasibility will be reached when 80% of the patients have successfully answered 80% of their respective questions scheduled for each treatment day. Furthermore, treatment-related patient satisfaction and diagnosis-related QoL is assessed by PSQ-18 and EORTC questionnaires at the end of radiotherapy and at the first follow-up.
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 will help to elucidate the treatment sites in the extremities and pelvis for which MR-guided HIFU heating is feasible, which has the potential to be beneficial for patients with conditions at those sites (soft tissue sarcoma, cervical cancer, etc.). The investigators anticipate that successful completion of this study will lead to clinical trials in those feasible sites of interest to determine the safety and efficacy of administering therapeutic levels of heat for hyperthermia or other applications.
This pilot phase I trial studies the side effects of durvalumab and tremelimumab in treating patients with muscle-invasive, high-risk urothelial cancer that cannot be treated with cisplatin-based therapy before surgery. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread.
