Active clinical trials for "Carcinoma, Renal Cell"

We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

The purpose of this study is to assess the influence of Sunitinib and Sorafenib on fatigue, quality of life and depression in patients with metastatic renal cell or colorectal cancer or GIST. In order to get more insight in the mechanism of vascular endothelial growth factor (VEGF) related fatigue and if possible to come to a resolution for this side effect.

The primary objective of this observational study is to retrospectively collect current survival data for patients originally included in axitinib A4061012 [NCT00076011] study to estimate the 5-year survival rate in subjects with metastatic renal cancer cell treated with axitinib.

The primary objective of the study is to evaluate the feasibility of 89Zr-bevacizumab PET imaging as a biomarker before and during treatment with sunitinib or bevacizumab plus interferon in patients with RCC. 89Zr-bevacizumab PET imaging will be regarded a promising biomarker if the target for treatment (VEGF) can be visualised and if uptake changes after institution of treatment.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at biomarkers that predict response to high-dose aldesleukin in patients with metastatic kidney cancer or metastatic melanoma.

The purpose of the study is to assess the effect of Sunitinib on tumor vascularization and necrosis in patients with metastatic renal cell cancer.

Retrospective study to collect data from Patients with advanced/metastatic renal cell carcinoma previously treated with Axitinib under standard clinical practice, to describe the clinical profile of the patients with a long response to Axitinib and to try to identify clinical factors which could be related with the long response to Axitinib, through the comparison between long responder patients and a group of refractory patients

This is a retrospective cohort study aiming to collect data on patients' characteristics, resource utilization, adverse events management and calculate costs attributed to current treatments of advance RCC patients who have received at least one prior VEGF-targeted therapy in Taiwan from National Health Insurance (NHI) perspective.

This is a pilot study to assess feasibility of dried blood spot (DBS) samples for pharmacokinetic measurements of targeted anti-cancer drugs in oncology patients such as patients with BRAF-mutant melanoma receiving targeted treatment with BRAF and MEK inhibitors.

Introduction The current limitations of renal cell carcinoma (RCC) imaging form a major deficit in the diagnostic pathway. Contrast Enhanced UltraSound (CEUS) has the potential to improve RCC detection and localization significantly. CEUS image interpretation is however difficult and subjective. To overcome these difficulties a CEUS quantification technique, Contrast-enhanced Ultrasound Dispersion Imaging (CUDI), has been developed in cooperation with the Eindhoven University of Technology (TU/e). Study objective Primary objective: To assess the sensitivity and specificity of CUDI for recognizing malignant tissue in vivo. Study population All patients scheduled for a partial or radial nephrectomy in the Amsterdam UMC (Amsterdam Universitair Medische Centra) Study Procedure This study is a prospective in-vivo study in patients scheduled for a partial or radical nephrectomy for a suspicious RCC in which we will perform CEUS imaging. The (partial) nephrectomy is part of standard care for patients with a suspicious lesion in the kidney. The additional ultrasound with infusion of an ultrasound contrast agent during ultrasound scanning is performed for the purpose of the study. CEUS imaging will be performed right before (partial) nephrectomy, with the patient being under general anesthesia. The CEUS and CUDI parametric maps will be interpreted by Investigator A in a blinded fashion with suspicious lesions each delineated. The (partial) nephrectomy will be performed by a qualified urologist, and the analysis of the histological specimens will be performed by a qualified pathologist. Sensitivity and specificity for CUDI will be calculated for all patients receiving a (partial) nephrectomy in which the tissue is sent for pathology. Benefits Currently, most renal tumors are diagnosed by abdominal US, CT or MRI. Renal tumors are classified as cystic or solid lesions on imaging. The most important criteria for differentiating malignant lesions is the presence of enhancement after administration of contrast for CT or MRI in several different phases (4 phases CT-scan). Enhancement in renal masses is determined by comparing Hounsfield units before and after administration of contrast. A change of 15 or more Hounsfield units demonstrates enhancement. Specificity and sensitivity for detecting RCC are around 75% and 88% for CT, and around 89% and 87.5% for MRI, respectively. Both CT and MRI can objectify a contrast-enhancing mass, suspicious for RCC, however, they cannot reliably distinguish a benign lesion (such as an oncocytoma or angiomyolipoma) from a malignant renal neoplasm. For that reason, patients are currently undergoing an RTB (renal tumor biopsy) to objectify pathology for deciding if treatment is necessary or not. Recent literature suggests up to 30% benign pathology after partial nephrectomy implicating overtreatment. RTB has been gradually introduced and increasingly used, however, an RTB is not without risks. Bleeding is the most documented complication. Recently even tumor tract seeding has been under discussion. Improving imaging by using CUDI for differentiating benign from malignant lesions instead of performing an RTB could prevent those risks for patients. Risk assessment There is a small risk of contrast-related adverse events (AE) for participants. After use in millions of patients, AE to the ultrasound contrast agent appear to be transient, mild and rare, and mostly consist of transient alteration of taste, local pain at the injection site and facial or general flush. In some cases, a mild allergic reaction is described. Patients will be informed of the risk during contrast exposure, and it will be described in the patient information file.
