Active clinical trials for "Carcinoma, Renal Cell"

The goal of this clinical trial is to better tell apart whether kidney tumors are benign (not cancer) or malignant (cancer) based on a biopsy or imaging tests and ask patients how they feel about decisions they make about treatment of their kidney tumor. The main objectives are: To estimate and compare the diagnostic accuracy of renal mass biopsy alone, PEER (with renal mass biopsy), and 99mTc-sestamibi SPECT/CT (with renal mass biopsy for hot tumors) to differentiate malignant and benign renal tumors. To estimate and compare the diagnostic accuracy of renal mass biopsy, PEER (with renal mass biopsy), and 99mTc-sestamibi SPECT/CT (with renal mass biopsy for hot tumors) to differentiate oncocytoma from chromophobe RCC. Participants will be asked to complete survey questions related to their health and kidney tumor at the start and end of the study. These can be done on paper, electronically, or by telephone.

The present study is a randomized clinical trial which investigates robot-assisted partial nephrectomy (RPN) compared to image-guided cryoablation (CA) in a number of functional, oncological and economic variables. Every year close to 1000 Danes are diagnosed with renal cell carcinoma. Approximately 25% of these newly diagnosed patients have a T1a tumour, thus being candidates to nephron-sparing surgery. Today most nephronsparing surgical procedures consists of RPN, often requiring temporary clamping of the renal artery rendering the kidney to a critical period of warm ischemia which is potentially harmful to the renal function. Image guided ablative modalities has emerged as a minimal-invasive alternative to partial nephrectomy. The level of evidence within this domain is considered to be low as the existing literature is highly influenced by selection bias, and as of yet no randomized trial has compared the two modalities. Especially with the increasing age of the patients, an approach suitable for local anaestesia is desirable. Patients from Central Denmark Region and Region of Southern Denmark who are diagnosed with a pT1a renal cell carcinoma that is found to be eligible for both modalities will be offered to enter into a randomized trial to be treated with either RPN og CA. The study's primary endpoint is loss of renal function 6 and 12 month after treatment. Secondary endpoint includes recurrence free survival 1, 3 and 5 years after treatment, readmission and complication rates as well as health economic evaluations. All patients will be pre- and postoperatively assessed with biochemistry, CT urography, CT thorax and glomerular filtration rate measurements.

Partial Nephrectomy has become the standard treatment in patients with tumours <7cm (T1). Even though this is a nephron sparing surgery, there is still potential for acute kidney injury, due to ischemia during the surgery. Remote Ischemia Preconditioning may prevent acute kidney injury and in turn chronic kidney disease. Remote Ischemia pre-conditioning involves applying a blood pressure cuff and inflating and deflating several times immediately prior to surgery.

Purpose: To evaluate the utility of simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) in characterizing the molecular subtypes of clear cell renal cell carcinomas (ccRCC) to potentially inform prognosis and treatment decisions. Participants: Seventeen subjects diagnosed with clear-cell renal cell carcinoma (ccRCC) will be imaged in a single session on PET-MRI. Procedures (methods): The investigators will image 17 ccRCC subjects on simultaneous PET-MRI and quantify the metabolically-active fraction of the tumor from images. Ten core samples will be taken from each tumor post-surgery and classified as ccA or ccB subtype using transcriptome analysis. The imaging-based measures will be correlated with the fraction of tumor cores classified as ccB.

The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.

Many patients who are candidates for nephron-sparing surgery, partial nephrectomy is now the standard treatment with a surgical, small, clinical T1 tumor (<7 cm). In many recent studies, partial nephrectomy provides equivalent oncologic, and superior functional, outcomes compared with the standard radical nephrectomy over the short and long term (2, 3). Partial nephrectomy techniques, whether open, laparoscopic or robotic, typically involve hilar clamping, which creates the desired bloodless operative field, allowing for more precise tumor excision and renal reconstruction. This hilar clamping eventually may lead to ischemic kidney injury which can compromise the functional outcomes of the remaining kidney.We are working now to develop a novel technique of Hypo-Perfusion by achieving partial renal arterial clamping, with the goal of completely eliminating surgical ischemia to the renal remnant.

One-arm clinical trial was adopted in this study. The surgeon performed remote urological surgery for patients through domestically produced "MicroHand" surgical robot system (Shandong Weigao Co., Ltd). The "MicroHand" surgical robot system consists of two physically separated subsystems named the "surgeon console" and "patient side cart". The surgeon console includes a stereo image viewer, two master manipulators, a control panel and several foot pedals. The patient side cart includes a passive arm that can slide in the up-down direction and be adjusted forward and backward, a swivel head that can rotate around the vertical axis, and three slave arms (one for the endoscopic camera and the other two for surgical instruments). The surgeon console (based in Qingdao) takes the surgeon's input and translates manipulation into a control signal. After network transmission, the patient side cart (based in other cities in Shandong Province) translates the control signal into actual instrument manipulation. The 3D images captured by the endoscopic camera were simultaneously sent back to the screen of the surgeon console as visual feedback. Data between the surgeon console and the patient side cart were transmitted through a 5G network. The safety and effectiveness of the robotic system in remote clinical diagnosis and treatment were verified by the main judgment criterion and secondary judgment criterion. Fifty patients with urinary diseases are planned to enroll in the clinical trial. Main judgment criterion: The robot-assisted telesurgery did not transfer to other types of surgery, such as open surgery or normal robot-assisted surgery. Secondary judgment criterion: operative time, blood loss, postoperative pain, preoperative adjusting time and hospitalization time. Patient enrollment: This trial aims to explore the safety and effectiveness of the domestically produced robotic system in remote clinical diagnosis and treatment through 5G network. Fifty patients with urinary diseases are planned to enroll in the clinical trial.

The number of people diagnosed with kidney cancer has doubled over the past 20 years, making it the eight most common cancer in the UK. Most tumours are less than 4cm in size, but over 80% of these are malignant (cancerous) and if left untreated, will slowly grow and spread. Current standard treatment for these small kidney cancers is to remove the diseased part of the kidney in an operation called a partial nephrectomy, but this can be quite a difficult operation. Because of the small tumour size and difficulties with the operation, other treatments have been developed to destroy the tumours. These treatments include radiofrequency ablation, which means that the tumour is destroyed by heat, and cryoablation, which means that the tumour is frozen and destroyed. Although removing the part of the diseased kidney in an operation is the tried and tested way to treat the kidney cancer, it does have risks and complications, such as bleeding. The other two treatments are less intrusive to the patient, and are less complicated as they do not require such a large operation as having part of the kidney removed, but it is not known if they are as good at destroying all of the tumour, and whether or not patients who have their tumour destroyed with these new methods require further treatment in future. In this study, the investigators are trying to determine if a large-scale study comparing these treatments is possible which is why this is called a feasibility study. The investigators are also looking at whether patients would be willing to be randomly assigned to a treatment group. The results of this study will then be compared to see how effective each of the treatments were and whether the number of patients who were happy to be randomly assigned to a treatment could be used to determine the number of patients required in a large-scale trial.

The purpose of this study is to investigate the use of a new anti-angiogenic drug called sorafenib, in combination with radiotherapy, for renal cell cancer that has spread to the bone and is causing significant pain. The study will find a safe dose of sorafenib for this combination study treatment, look at side effects, and test if the study treatment is effective in controlling the pain experienced from this type of renal cell cancer. . There will be two parts or phases to this study The purpose of the first phase is to find the highest dose of sorafenib that can be given safely to patients, when combined with radiotherapy. We will also see what kind of effects the study treatment has on you and your cancer. Participants in this phase will receive a dose of sorafenib that has shown to be well-tolerated in humans. If the side effects are tolerable for this dose of sorafenib when combined with radiotherapy, new patients will be asked to join the study and will receive a dose of sorafenib higher than the last study participant. In the second phase, new study participants will receive the dose of sorafenib that was determined to be safe in the first phase. Side effects will continue to be looked at and the effectiveness on controlling pain symptoms from this type of cancer, will also be looked at.
