Active clinical trials for "Kidney Neoplasms"

The aim of this study was to show additional diagnostic criteria of computed tomography (CT) scan to diagnose and predict the detection and recurrence of cystic renal cell carcinoma in the patients with complicated renal cysts. Furthermore, we would demonstrate the relationship between complicated renal cysts diagnosed by Bosniak system and some parameters of pathological results. The analysis about detection time of renal malignancy would help determine the practical guidelines of follow-up plan for complicated renal cysts.

This clinical trial studies gene analysis in studying susceptibility to Wilms tumor. Finding genetic markers for Wilms tumor may help identify patients who are at risk of relapse.

Active surveillance in kidney cancer involves closely observing the tumor with periodic imaging studies rather than immediately proceeding to an invasive treatment. This does not mean that the tumor is ignored or that future treatment is not necessary, rather it means the tumor does not require treatment at this time. On active surveillance, a tumor is closely monitored without treatment, however if the tumor changes and reaches a predefined threshold that your physician no longer considers safe, your physician will strongly encourage treatment.

This research study is studying biomarkers in tissue samples from younger patients with Wilms tumor. Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict how patients respond to treatment

Investigators will conduct a randomized trial to determine if providing patient-specific life expectancy estimates during treatment counseling via a targeted, patient-centered communication approach improves shared decision making and reduces rates of overtreatment of genitourinary malignancies.

Data from the American Cancer Society shows a 70% increase in incidence of kidney and renal pelvis cancer between 2000 and 2010. This increase is attributed to small renal masses (SRM) that are incidentally discovered by abdominal radiological imaging. However, 30% of resected SRMs appear benign on histological examination. Conventional biopsy is currently used to provide pathological information prior to resection. However, its non-diagnostic value is high, up to 33% in SRMs, showing the need for diagnostic improvement. The investigators have shown that optical biopsy (OB) can differentiate malignant from benign tissue and tumor subtypes. However, translation to the clinic requires a phase 2 clinical study. The investigators will use an OB probe that can be combined with a needle puncture during classical biopsy procedures, additionally providing real time micro-scale images containing quantitative information about tissue properties. The investigators are convinced that OB will greatly improve the diagnosis of renal tumor pathology.

The main objective of study is to describe the priorities of elderly patients (70 years and over) undergoing a first medical treatment for cancer, at initiation of treatment and after 3 months of treatment. The main criterion is a prioritization of 4 items per patient from a list of 8 expectations regarding the objectives of their treatment: treatment efficacy, life expectancy, autonomy, daily activities, social activities, heaviness of treatment, toxicity, economics.

The purpose of this project is to analyze tumour tissue from a group of subjects with renal cell carcinoma, who have been treated at the Royal Marsden Hospital.

Often kidney cancer is diagnosed when the tumour is small and hasn't spread. Rather than major surgery to remove the whole kidney, image-guided ablation involving heat (microwave or radiofrequency) or freezing (cryotherapy) is often used to destroy the tumour using minimal invasive technique with much less risk and discomfort. Limited evidence suggests that ablation also activates the immune system which may help in fighting the cancer. We will investigate the immune and other changes by analysing blood samples from patients before and after ablation. Understanding this will help in designing more effective new treatments combining ablation with biological therapies.

Generally, in the trials, an observant patient is described as correctly taking 90 to 100% of the prescribed doses. Here, the 80% compliance rate will be the cut-off between observant and non-observant patients. The evaluation methodology is based primarily on a survey of patients with metastatic or locally advanced kidney cancer who have just began an oral treatment protocol. The constitution of this cohort will be made from newly treated patients included by oncologists. The survey consists of implementing a series of questionnaires with each patient of the sample throughout the course of oral cancer care. This series of questionnaires will aim to identify: the gradient of compliance of the patient with his treatment, all the factors likely to influence positively or negatively the latter, whether medical, material or socio-economic, the evolution of patient compliance during their treatment course, a patient's quality of life index through the standardized quality of life survey form (EORTC - Quality of Life Questionnaire QLQ C30 version 3). These questionnaires will be supplemented by the medical record data (including information on tolerance and possible drug interactions). The representativeness of the patients surveyed will be established by comparing the statistical characteristics of the surveyed population with those of the aggregate anonymous global data obtained by the two Medical Department of the French Regional Health Insurance of the two regions. From the data compiled by this study, different econometric models of patient behavior will seek to establish, in particular, a relationship between the probability that a given patient will be either non or poorly observant and the various variables proved to be statistically significant.
