Active clinical trials for "Kidney Neoplasms"

Longitudinal study nonrandomized, multicenter observational descriptive monitoring patients treated with anti-angiogenic for metastatic kidney cancer

Background: - The experimental contrast agent [18]F-Fluciclatide is being tested for cancer treatment imaging studies. It is designed to show tumors in which new blood vessels are growing. Imaging studies with [18]F-Fluciclatide may help predict how well a tumor will respond to therapy that will prevent the growth of new blood vessels. Researchers will test [18]F-Fluciclatide before beginning treatment and after the first treatment cycle. Participants may also have a third scan with [18]F-Fluciclatide between 2 and 7 days after starting treatment to look for changes in blood vessel growth early after starting therapy. Objectives: - To test the safety and effectiveness of [18]F-Fluciclatide in predicting cancer treatment outcomes. Eligibility: - Individuals at least 18 years of age who will have kidney cancer treatment to stop tumor blood vessel growth. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Tumor imaging studies and biopsies will be performed before starting the study. Participants will have two positron emission tomography (PET) and computed tomography (CT) scans. [18]F-Fluciclatide will be used for each scan. One scan will happen before the start of cancer treatment, and the second will happen after the first treatment cycle. Participants may also have an optional third PET/CT scan with [18]F-Fluciclatide. This scan will take place 2 to 7 days after beginning therapy. Depending on the location of the tumor, some participants may have an optional magnetic resonance imaging scan to look for changes in tumor blood flow and size. These scans will be done within 3 weeks of each [18]F-Fluciclatide PET/CT scan. The scans will be monitored with regular blood tests and vital signs. Participants will be followed for up to 1 year after the study to look for overall disease response to therapy.

This randomized pilot early phase I trial studies the side effects and how well nivolumab alone works compared to nivolumab with bevacizumab or ipilimumab before surgery in treating patients with kidney cancer, also referred to as renal cell cancer, that has spread to another place in body and can be removed by surgery. Immunotherapy with monoclonal antibodies, such as nivolumab, bevacizumab, and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This is a prospective study lasting 36 months , where 1120 patients with surgical diseases in programming for the following operations will be studied : transthoracic esophagectomy ; subtotal gastrectomy with lymphadenectomy ; partial pancreatectomy ; resection of the rectum ; prostatectomy ; cystectomy ; partial nephrectomy ; hysterectomy with or without pelvic and paraaortic lymphadenectomy ; resection of malignant tumors of the mouth and orofaringolaringe and lung lobectomy . Patients will come from the outpatient services of the Institute of Cancer of São Paulo - ICESP

Patients with renal cancer are commonly treated by robot-assisted partial nephrectomy. Renal artery clamping is commonly required inducing kidney ischemia during surgery. It impacts parenchymal and renal function. This study aims to compare a new surgical procedure in order to reduce ischemia effect and preserve renal function after partial nephrectomy for renal tumour.

Irreversible Electroporation (IRE) is an emerging technique delivering electrical pulses to ablate tissue, with the theoretical advantage to overcome the main shortcomings of conventional thermal ablation. Recent short-term research showed that IRE for the ablation of renal masses is a safe and feasible treatment option. In an ablate and resect design, histopathological analysis 4 weeks after radical nephrectomy demonstrated that IRE targeted renal tumors were completely covered by ablation zone. In order to develop a validated long-term IRE follow-up study, it is essential to obtain clinical confirmation of the efficacy of this novel technology. Additionally, follow-up after IRE ablation obliges verification of a suitable imaging modality. The objectives of this study are the clinical efficacy and safety of IRE ablation of renal masses and to evaluate the use of cross-sectional imaging modalities in the follow-up after IRE in renal tumours. This is a prospective, human, in-vivo study among 20 patients presenting with solid enhancing SRM on cross sectional imaging suspect for renal cell carcinoma (RCC). Preoperatively, imaging is required through Magnetic Resonance Imaging (MRI), Contrast-enhanced ultrasound (CEUS) and contrast-enhanced Computed Tomography (CT). Furthermore, serum creatinine levels and VAS scores are obtained. A biopsy of the SRM will be performed in preoperative setting. IRE ablation will be performed using CT-guidance and ablation success will be measured directly after the ablation through contrast-enhanced CT. Device related adverse events (AE) will be registered using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 guideline. One week post ablation only CEUS and MRI will be performed to limit exposure to ionizing radiation. At 3 months, 6 months and 12 months post ablation CEUS, MRI and CT will be performed. Additionally, at these time points serum creatinine levels and VAS scores will be obtained, and quality of life will be assessed through SF-36 questionnaires. Residual and recurrent disease will be assessed through tissue enhancement on cross sectional imaging.

Surgery plays a central role in kidney cancer management being the only therapy that offers the possibility of healing the patients. Currently, the partial nephrectomy is a standard technique because it meets the principle of nephron sparing surgery. A partial nephrectomy requires a control of the renal blood flow using a clamp, which can be parenchymal or vascular (pedicular). In France, most of the centers use pedicular clamping. It is well established that this technique results in warm ischemia of the entire healthy parenchyma and can lead to permanent kidney damages. Currently, no study evaluated the impact of parenchymal clamping on the healthy parenchyma. The aim of the investigators study is to evaluate the nephrotoxicity of the healthy parenchyma due to parenchymal clamping during partial nephrectomy. This assessment will be done through a microdialysis technique. The microdialysis probe is directly implanted in the healthy unclamped parenchyma and will allow us to measure in real time, during the surgery, the biological changes related to anaerobic metabolism of renal interstitial space. All those measures will be completed by urinary and plasmatic assessments. Oxidative stress will be assessed using four markers of tubular viability : Interleukin 18 (IL18), Kidney Injury Molecule-1 (KIM-1), Neutrophil Gelatinase-Associated Lipocalin (NGAL) and cystatin C and four parameters of anaerobic metabolism : lactate, pyruvate, glycerol and glucose. This is a prospective pilot study limited to 10 patients included over 12 months. Depending on the results, it will be further developed by a second study comparing parenchymal with pedicle clamping.

RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying the side effects of giving sunitinib malate and to see how well it works in treating patients with locally recurrent, locally advanced, unresectable, or metastatic urinary tract cancer.

RATIONALE: Studying the genes and proteins expressed in tissue samples from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This laboratory study is evaluating gene and protein expression in normal tissue and tumor tissue from patients who have undergone surgery for kidney cancer.

RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sunitinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving it after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying how well sunitinib works when given before and after surgery in treating patients with stage IV kidney cancer.
