Active clinical trials for "Kidney Neoplasms"

The purpose of this study is to study the change of tumor size and serum cytokine in the patients who received cryotherapy for the renal tumors.

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 primary aim of this study is to establish if it is possible for patients who have undergone major body surgery to complete a home based exercise training program and complete the assessments required to measure physical and cognitive function. If the investigators can establish that it is feasible to complete the training and test's then further research can follow using these methods to determine whether it is possible to improve the physical function of older patients undergoing major abdominal surgery in the period following surgery by using a simple exercise regimen that can be carried out at home. By targeting physical function in this way the investigators hope to determine if it is a method for improving frailty and well being. In turn it may also have a positive impact on health service provision.

In this study, the researchers will examine the effects of post-mindfulness intervention email and text messages to promote maintenance of intervention effects over time in a uro-oncology sample (clinically localized prostate, kidney, and bladder cancer) of patients and spouses.

This randomized pilot clinical trial studies sildenafil citrate before surgery in improving kidney function in patients with kidney cancer. Sildenafil citrate may help protect the kidney from the side effects of surgery and improve kidney function after surgery.

This randomized pilot clinical trial studies body warming in improving blood flow and oxygen delivery to tumors in patients with cancer. Heating tumor cells to several degrees above normal body temperature may kill tumor cells.

Disease and Stage: Metastatic and locally advanced clear cell renal carcinoma An open-label, exploratory, single-arm, multicenter trial. Everolimus will be administered orally, once daily, for 6 weeks followed by a 1-week rest period prior to nephrectomy. Two to four weeks after surgery, everolimus will be reintroduced only for metastatic patients until disease progression, unacceptable toxicity, withdrawal of patient consent, or other stopping rules are met.

Objectives: The purpose of this study is to find out if a new program can help kidney cancer survivors (KCS) increase their physical activity (PA) and improve their quality of life (QoL). Methods: Fifty KCS will be recruited from a previous study using the Alberta Cancer Registry. Participants will undergo submaximal exercise testing, a physical function test and measures of height and weight, which will be completed at baseline and the end of the physical activity program (at 12 weeks). Participants will also complete questionnaires on PA and QoL at the baseline, after the supervised portion of the program (at 4 weeks), and at the end of the entire program (at 12 weeks). Following baseline assessments, participants will be randomly assigned to either: (1) supervised physical activity plus traditional exercise counseling or (2) supervised physical activity plus behavioural counseling. Participants will be asked to attend six individual supervised exercise and counseling sessions over a 4-week period with a PA specialist that eventually tapers to a home-based program by the end of the program. Implications: The investigators hope that this PA intervention for KCS is feasible and results in meaningful improvements in health outcomes that can be translated to public health practice.

RATIONALE: Glutamic acid may help lessen or prevent nerve damage caused by vincristine. It is not yet known whether glutamic acid is more effective than a placebo in preventing nerve damage in patients receiving vincristine for Wilms' tumor, rhabdomyosarcoma, acute lymphoblastic leukemia, or non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying glutamic acid to see how well it works compared to a placebo in reducing nerve damage caused by vincristine in young patients receiving vincristine for Wilms' tumor, rhabdomyosarcoma, acute lymphoblastic leukemia, or non-Hodgkin's lymphoma.

RATIONALE: Glutamine may help lessen neuropathy caused by chemotherapy. It is not yet known whether glutamine is more effective than a placebo in treating neuropathy caused by vincristine. PURPOSE: This randomized phase II trial is studying glutamine to see how well it works compared to a placebo in treating neuropathy caused by vincristine in young patients with lymphoma, leukemia, or solid tumors.
