Filter by:Brain metastases are the most common intracranial malignancy occurring in 20-40% of all cancers, and the presence of CNS metastases is associated with a poor prognosis. As such, the median overall survival of patients with symptomatic brain lesions is a dismal 2-3 months regardless of tumor type. Because standard chemotherapy largely does not cross the blood brain barrier at a meaningful concentration, standard treatment is limited and usually involves surgical resection and/or stereotactic radiosurgery for isolated lesions and whole brain radiation for multiple lesions. Unfortunately, the median overall survival is only improved by about 6 months with this multimodality approach2, and there is a paucity of second-line therapies to treat recurrence. Furthermore, re-resection and re-radiation are often not feasible options due to concern for increasing complications or neurotoxicity, respectively. Thus, there is a dire clinical need for additional treatment options for this patient population. Checkpoint blockade therapy, in particular PD-1 and PD-L1 inhibition, has recently shown clinical efficacy in multiple types of solid tumors. The investigators propose to study the efficacy of checkpoint blockade therapy in patients with solid tumors and refractory/recurrent brain metastases. The investigators will assess the efficacy of MEDI4736, a novel PD-L1 inhibitory monoclonal antibody, in this study.
Surgery plays a central role in kidney cancer management being the only therapy that offers the possibility of healing the patients. Currently, the partial nephrectomy is a standard technique because it meets the principle of nephron sparing surgery. A partial nephrectomy requires a control of the renal blood flow using a clamp, which can be parenchymal or vascular (pedicular). In France, most of the centers use pedicular clamping. It is well established that this technique results in warm ischemia of the entire healthy parenchyma and can lead to permanent kidney damages. Currently, no study evaluated the impact of parenchymal clamping on the healthy parenchyma. The aim of the investigators study is to evaluate the nephrotoxicity of the healthy parenchyma due to parenchymal clamping during partial nephrectomy. This assessment will be done through a microdialysis technique. The microdialysis probe is directly implanted in the healthy unclamped parenchyma and will allow us to measure in real time, during the surgery, the biological changes related to anaerobic metabolism of renal interstitial space. All those measures will be completed by urinary and plasmatic assessments. Oxidative stress will be assessed using four markers of tubular viability : Interleukin 18 (IL18), Kidney Injury Molecule-1 (KIM-1), Neutrophil Gelatinase-Associated Lipocalin (NGAL) and cystatin C and four parameters of anaerobic metabolism : lactate, pyruvate, glycerol and glucose. This is a prospective pilot study limited to 10 patients included over 12 months. Depending on the results, it will be further developed by a second study comparing parenchymal with pedicle clamping.
This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.
Advanced renal cell carcinoma is invariably fatal, with a life expectancy of 2-3 years since diagnosis. Sunitinib is the standard first-line treatment for this condition, but it is associated to multiple side effects, with fatigue being reported in 51-63% of patients. As sunitinib-induced fatigue is likely to be mediated by inhibition of AMPk function, the investigators hypothesize that isoquercetin, which is hydrolyzed in vivo to quercetin, a known AMPk activator, is able to reduce fatigue in kidney cancer patients taking sunitinib.
This is a prospective, single-center randomized trial with three arms, and an allocation ratio of 1:1:1. The study design is an efficacy study to evaluate the effect of metformin and coach-directed behavioral weight loss versus self-directed weight loss on insulin-like growth factor (IGF)-1 and IGF-1 to THE IGFBP-III ratio blood levels after 6 and 12 months of intervention. The coach-directed Behavioral Weight Loss arm is a web-based remote delivery and communication system that promotes healthy behavioral changes. The Metformin arm is a pharmaceutical intervention of oral metformin. This is a secondary prevention study for men and women who have survived solid malignant tumors
The investigators will determine the cancer risk in organ transplant recipients compared to the general population with the help of statistical analysis. Secondly the investigators will try to characterize the different cancer types.
Background: Electroporation or electropermeabilisation is a novel technique with the potential to overcome the main disadvantages of thermal ablation. It utilizes electric pulses, traveling between two or more electrodes, to create 'nanopores' in the cell membrane. If the applied current reaches a certain threshold these 'nanopores' become permanent resulting in cell death. The use of electric current means that IRE is not susceptible to 'thermal sink' leading to consistent ablation results. IRE ablation targets the cell membrane, sparing tissue architecture and minimizing damage to blood vessels, nerves and the renal collecting system. The first in human studies have proven the safety of IRE for the ablation of small renal masses. However the efficacy of IRE through histopathological examination of an ablated renal tumour has not yet been studied, compromising the correct and scientific evaluation of this new technology. Primary Objectives: - To determine the efficacy of IRE ablation of renal masses , measured by histopathologic examination of the targeted tumour. - To determine the safety of IRE ablation of renal masses, by evaluating device and procedural adverse events. Secondary Objectives: - To evaluate the efficacy of MRI in the imaging of ablation success, extend of the ablation zone, one and four weeks post IRE ablation. - To evaluate the efficacy of CEUS in the imaging of ablation success, extend of the ablation zone, one and four weeks post IRE ablation. Population: 10 patients, age ≥ 18 years, presenting with a solid enhancing mass, who are candidates for radical nephrectomy. Intervention: Eligible patients will receive IRE ablation of their renal mass 4 weeks prior to radical nephrectomy. Follow-up at one and four weeks post IRE will be performed using MRI and CEUS imaging. After radical nephrectomy histopathological examination will be performed to evaluate IRE ablation success.
PART 1: The primary objective of this study is to identify the maximum tolerated dose (MTD) of MK-3795, formerly called PT2385 and/or the recommended Phase 2 dose (RP2D) of MK-3795 in patients with advanced clear cell renal cell carcinoma (ccRCC). PART 2: The primary objective of this study is to identify the MTD of MK-3795 up to the RP2D, in combination with nivolumab, in patients with advanced ccRCC.As of Amendment 09 (29 Mar 2024), participants with advanced ccRCC will transition from MK-3795 to belzutifan (MK-6482) in combination with nivolumab or belzutifan alone. PART 3: The primary objective of this study is to identify the MTD of MK-3795 up to the RP2D, in combination with cabozantinib tablets, in patients with advanced ccRCC.
Identifying clinical factors such as medication, background diseases and blood tests that effect the course of disease in cancer patients can help physicians to better decide on the patient's treatment plan. The study seeks to identify and analyze relevant clinical factors that effect the course of the disease and the results of treatment in patients with cancers of the prostate, bladder and kidney.
Standard treatment for kidney cancer is to remove the tumors from the body with surgery. The purpose of this clinical trial is to collect, preserve, and store excess kidney cancer tumor specimens that would normally be discarded after surgery.
