Active clinical trials for "Kidney Neoplasms"

Prospective, monocentric, single arm, observational PMCF - Study on the Performance and Safety of Double-Shank Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)

A non-interventional, medical record review of clinical data collected from Japanese participants with recurring kidney cancer

The Engagement of Patients with Advanced Cancer is an intervention that utilizes well-trained lay health coaches to engage patients and their families in goals of care and shared decision-making after a diagnosis of advanced cancer. Although lay health workers have never been tested in this role, we hypothesize that lay health workers can feasibly improve goals of care documentation and help to reduce unwanted healthcare utilization at the end of life for Veterans diagnosed with new advanced stages of cancer and those diagnosed with recurrent disease.

RATIONALE: Studying samples of blood, tissue, or bone marrow from patients with cancer in the laboratory may help doctors to learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research trial studies biomarkers in samples from younger patients with Wilms tumor.

To determine the feasibility of representative urologic procedures as measured by the rate of conversions

Background: In Central Europe, mortality rates for kidney cancers are higher and survival rates are lower than in the United States and Western Europe overall. The Central and Eastern European Renal Cancer Case-Control Study (CEERCC), completed in 2002, offers an opportunity to identify determinants that predict 5-year survival among kidney cancer patients. Objectives: To assess disease recurrence and progression among former participants in the CEERCC. To investigate the effect of genetics, lifestyle factors, medical conditions, occupation and diet on the outcome of kidney cancer patients in Europe. Eligibility: Former participants or next-of-kin of former participants in the CEERCC study. Design: Participants or their next-of-kin are interviewed for 60 minutes and are requested permission to collect relevant information from their or their family member s hospital and cancer registry records.

Circulating tumor cells (CTCs) have prognostic value in several tumor types, and increasing evidence suggests that molecular characterization of CTCs can serve as a "liquid biopsy" to understand and address treatment resistance. The goal of this proposal is to demonstrate that CTCs can be accurately enumerated and characterized in metastatic clear cell renal cancer (CCRC) and can serve as prognostic/predictive biomarkers to improve treatment. The challenge surrounding CTC analysis in CCRC is that most CTC technologies (including the clinical gold-standard CellSearch®) depend in epithelial markers such as EpCAM that are expressed at low or heterogeneous levels in CCRC. Members of the research team have developed a novel CTC microfluidic technology that can effectively detect CTCs that are completely undetectable by CellSearch® because of very low EpCAM expression, as well as allowing for CTC recovery for downstream molecular characterization. The goal of this proposal is therefore to test the hypotheses that (1) The microfluidics CTC technology will have better sensitivity/specificity relative to the CellSearch in metastatic CCRC; and (2) Enumeration of CTCs in metastatic CCRC patients (n=66) will have prognostic value, while molecular characterization of CTCs for expression of biomarkers (VHL, VEGF, mTOR, HIF1/HIF2, AKT) related to CCRC etiology will be predictive of response/resistance to targeted therapies. Although CCRC is relatively uncommon, the lack of established adjuvant treatments and high cost of targeted therapies in the palliative setting makes the search for new prognostic/predictive biomarkers an important clinical goal.

Background: High blood pressure is a common complication observed in cancer patients prescribed anti-VEGF drugs. Increased blood pressure increases the risk of heart attacks and strokes, thus adversely affecting survival and quality of life in this patient group. However, little is known about the mechanisms leading to high blood pressure with anti-VEGF drugs. As a result, the management of anti-VEGF drug-induced hypertension is largely empirical. A better knowledge of effects of specific blood pressure lowering drugs, i.e. antihypertensives, on anti-VEGF drug-induced hypertension would optimize therapeutic management and reduce the risk associated with hypertension and proteinuria in patients with cancer. Methods: Datasets of two completed GSK clinical trials using the anti-VEGF drug pazopanib, i.e. VEG108844 and VEG105192, will be accessed to 1) determine the way blood pressure changes over time after commencing anti-VEGF treatment; 2) identify whether there are any relationships between pre-study and baseline blood pressure values, treatment with specific antihypertensive drugs, and changes in blood pressure after commencing anti-VEGF treatment; and 3) identify whether specific antihypertensive drugs and drug combinations, prescribed either before or after commencing anti-VEGF treatment, lead to a better blood pressure control and prevent proteinuria during anti-VEGF treatment. Specific statistical analyses will be conducted to assess and identify associations and will account for other patient's characteristics and repeated observations over time. The investigators plan to conduct this study over 6 months. Studies VEG108844 and VEG105192 have been selected as they investigate the same anti-VEGF drug, pazopanib, in a homogeneous group, i.e. patients with renal cancer. At the same time, inclusion of a placebo arm as well as a treatment arm with a different anti-VEGF drug, sunitimib, will allow initial comparisons across different groups. The results deriving from this study will provide important knowledge on 1) patterns of blood pressure changes with anti-VEGF drugs and 2) whether specific antihypertensive drugs or drug classes might be better than others in preventing and managing anti-VEGF induced hypertension and proteinuria.

This is a non-interventional, multicenter study to evaluate efficacy and safety of intravenous bevacizumab (Avastin) in combination with interferon alpha-2a immunotherapy for first-line treatment in participants with advanced and/or metastatic renal cell cancer (mRCC) in daily routine.

RATIONALE: Studying samples of tissue from patients with rhabdoid tumors in the laboratory may help doctor learn more about changes that occur in DNA and identify genes related to cancer. PURPOSE: This research trial studies biomarkers in samples from young patients with rhabdoid tumors.
