The frequency of kidney tumors found incidentally on imaging studies performed for unrelated reasons continues to increase leading to more surgeries and ablations for the treatment of renal masses thought to be cancer. However, about 20% of these masses are not cancerous and do not require treatment. Many cancerous kidney tumors are indolent and can be followed safely with imaging (i.e., particularly tumors <2 cm and in patients with limited life expectancy), while some tumors are both malignant and aggressive, with a higher potential to spread outside the kidney and require treatment. The purpose of this observational study is to assess the ability of Fludeoxyglucose (18F) (FDG) PET/MR to distinguish different types of kidney tumors. The investigators hypothesize that PET/MR will better show differences between aggressive and both indolent and benign kidney masses compared to the currently used radiologic scans. Participants will be selected from those who have been scheduled to receive a contrast-enhanced MRI for their regular care due to a suspicious kidney mass. Participants will have their MRI on a hybrid PET/MR scanner capable of obtaining both MRI and PET images. While they are receiving their standard of care MRI exam, patients will also receive a research FDG PET exam. Participants will have an IV placed for administration of the MRI contrast agent, just as they would if they were not taking part in the study. The same IV will be used to give the FDG radiopharmaceutical for the PET scan and furosemide (a diuretic), to help empty the bladder before the scan and help better see the kidneys on the scans. Both FDG and furosemide are FDA approved medications. Participants will have only one visit with the research team which will last ~2.5 hours and will include collection of the participant's regularly scheduled MRI. If participants undergo surgery to remove the tumor, the study will collect samples of the removed tissue for research. If participants receive a biopsy of the tumor, the study may collect an additional sample of the tumor for research. After the PET/MRI, participants will not have additional visits with the study team, but the study team may call every 6-12 months for up to 2 years to see how they are doing and ask about their health. The study team will review the medical record for any changes to their diagnosis, updates to their medical history, new scans ordered by their regular doctor, or recent lab or biopsy results.
The goal of this observational study is to learn about the value of 18F-FAPI-RGD PET/CT imaging in Renal Tumor. Participants will undergo clinical evaluation and 18F-FAPI-RGD PET/CT examination.
The purpose of this study is to determine if the novel TR approach is superior to the standard RP approach. The anticipated study outcome is a time saving of at least 30% from first skin incision to detection of the renal artery compared to the conventional RP approach, and also a better workspace perception by the operating surgeon.
To compare safety and efficacy between open and robotic partial nephrectomy in treatment of organ confined complex renal tumors (R.E.N.A.L score more than 7) as regarding surgical results, morbidity, clinical as well as oncological and functional outcomes.
The aim of our study is to assess the long-term oncological and functional outcomes of cryoablation for T1b renal tumors, as well as such important parameters as the patient's quality of life after treatment, and to compare the results with those after partial nephrectomy.
This is a pilot study to assess acute toxicity in patients receiving flank irradiation using proton therapy for renal tumors.
Renal Cell Carcinoma (RCC) is the most common type of kidney cancer. The usual treatment for this type of cancer is surgery. Considering the most common patients are an average age of 65 and some are not suitable candiates for surgery, there is great interest in non-surgical alternatives for kidney cancer treatments. This study will investigate the use of Stereotactic Ablative Radiosurgery (SABR) for renal tumors. SABR is a non-invasive alternative, which involves delivery of high doses of radiation to the target, while minimizing the risk of injury to the surrounding organs. Patients will be seen before and end of treatmetn and will be followed at 4 month intervals for up to 2 years. During the follow ups, patients will be asked to complete a quality of life questionnaire and will have standard of care imaging.
NiSAR is a Ph.D. study and consists of three substudies. Renal cancer is one of the most deadly urologic malignancies and accounts for 900 new cases and 300 deaths per year. An increase in the use of imaging diagnostics has yielded a rise in the incidental detection of small renal masses (SRM), meaning tumors <4cm (T1a). Kidney biopsies are the gold standard for diagnosing SRM but has an inherent risk of infections, retroperitoneal bleeding and in rare cases loss of kidney function. This is problematic since up to 30% of SRM are benign. This Ph.D. consists of three studies that all aim to develop new minimally invasive modalities for diagnosing SRM. Patients eligible for these studies are diagnosed with SRM at one of the departments of Urology in the southern region of Denmark. Studies 1 and 2 aims to find circulating biomarkers, in the form of DNA and messenger ribonucleic acid (mRNA) contained in micro vesicles secreted into blood by renal cell cancers and find changes in biomarkers levels after surgery. Study 3 aim to determine the potential of multiplanar MRI (mpMRI) to discriminate between benign and malign SRM. Potentially this can lead to a fundamental change of the way urologists diagnose and monitor SRM and renal cell cancer in general. The investigators will also build a research biobank for future research.
