Filter by:The aim of this study is to gain a better understanding of the phenomenon of adherent perinephric fat (APF), which occurs in some patients undergoing partial nephrectomy (PN). This phenomenon, so-called "toxic fat", is a commonly recognized problem among urologists, but its significance has not yet been fully understood. The study aims to identify new clinical risk factors for APF occurrence and evaluate its impact on functional, perioperative, and oncological treatment outcomes. The study will be conducted on patients who are qualified for PN surgery. Prior to the surgical procedure, venous blood will be collected, which will be used for various measurements, such as blood morphology, kidney parameters, inflammation markers, liver function tests, glucose, and lipid profile. In addition, medical data will be collected concerning the patient's overall health, observed changes in the kidney, perioperative course, hospitalization, and histopathological characteristics of the tumor. After treatment, patients will be followed up for up to 60 months. The knowledge gained from this study can significantly assist in making decisions about surgical treatment and thus contribute to improving the treatment outcomes of patients with kidney tumors.
The study of the blood concentration of ITK what are pazopanib and cabozantinib at 1 month and 3 months from the start of treatment will allow to evaluate the impact of renal failure on their efficacy and toxicity in patients with metastatic kidney cancer.
The purpose of the open-label INDIGO-study is to examine whether a first line individualized treatment strategy based on DNA and RNA analyses from the patient's tumor is feasible. Moreover, to involve the patient further in their treatment via patient-reported outcomes (PRO) measurements in a value-based healthcare setup with simultaneous analyses of the financial costs of this strategy. The patients are assigned into 4 treatment arms according to the results of their DNA and RNA analyses. All patients receive electronic questionnaires regarding symptoms and side effects weekly and questionnaires regarding quality of life monthly. Based on each patient's answers of the questionnaires the patient receives advices in the app to reduce the symptoms and side effects or the patient is instructed to contact the hospital. The hypothesis: Basing the choice of first-line treatment for DNA mutations and RNA profiles in a heterogeneous patient population increases the overall response rate for the total population to 30% compared to 10% for historical cohorts.
The Investigators will use novel PDX (patient-derived xenograft) technology to form xenografts using material from metastatic solid tumor patients. Xenografts will be treated with a panel of drugs to determine which agent(s) yield the greatest anti-tumor effect on the xenograft.
This feasibility study will evaluate how well hyperpolarized 13C pyruvate magnetic resonance imaging (MRI) scan works in predicting tumor aggressiveness in participants with renal tumors. Hyperpolarized 13C pyruvate is a non-radioactive substance with potential usage in the diagnostic imaging of tumors. Hyperpolarized 13C pyruvate MRI may help doctors determine non-invasively whether a kidney tumor is a benign tumor or cancer, and if cancer, how aggressive it is. This may help doctors and participants with renal tumors in the future to make better treatment decisions.
This trial studies how well technetium Tc-99m sestamibi single-photon emission computed tomography/computed tomography (SPECT/CT) works on clinical decision making in patients with kidney tumors. Diagnostic procedures, such as technetium Tc-99m sestamibi SPECT/CT may be a less invasive way to check for kidney tumors.
Retrospective studies indicate that active surveillance for clinically localized, small renal masses (cT1a, <=4cm) is safe. It is our hypothesis that active surveillance is safe and efficacious when compared prospectively to patients undergoing immediate intervention for their small renal mass.
Approximately 30,000 new patients are introduced into dialysis and about 20,000 of them die every year in Japan. At present, about 300,000 patients are on dialysis and more than 10,000 patients are registered with the Japan Organ Transplant Network (JOTN) with the hope for a renal transplantation. If the renal function is restored by transplantation, the quality of life (QOL) improves and more than 90% are reportedly comeback to their normal life activities and get relieved from the burden of dialysis. Furthermore, it can reduce the dialysis related medical cost by as much as 50%. However, only about 1,000 renal transplantation cases are annually carried out in Japan. Among them, 80-85% are living renal transplantations offered by family members or relatives, and the rest are from deceased donors. Due to the fact that the number of deceased donors are scarce and only living renal transplantations between the family members or relatives are currently allowed in Japan, the approximate waiting time to receive a renal transplantation is 16 years. For that reason, many patients travel abroad to receive a renal transplantation. There are reports that total nephrectomies are performed as a treatment for small size (4 cm or less) renal tumors, renal stones, ureteral tumors and ureteral strictures in many cases and that many of these nephrectomized kidneys can be successfully transplanted after surgical restoration with satisfactory results. However, due to the lack of necessary evidence it is currently not allowed in Japan. Therefore, the investigators planned the present clinical study to evaluate the curative efficacy (renal function, QOL) and safety (side effects, complications or occurrence of renal cancer) of living renal transplantations between family members and relatives with restored donor kidneys after the surgical removal or repairment of a small size (4 cm or less) renal tumor or renal stone, ureteral tumor or ureteral stricture, in order to acquire necessary clinical data for potential enrichment of the renal donor pool in Japan as well as to develop useful medical care for our patients who are on dialysis for many years due to the renal failure.
This research trial studies kidney tumors in younger patients. Collecting and storing samples of tumor tissue, blood, and urine from patients with cancer to study in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.
