The purpose of this study is to study the effect of variations in the arterial CO2 concentration during deep neuromuscular block on the surgical conditions as assessed by the surgical rating scale
The purpose of this study is to better understand how effective ablation is for destroying tumor cells in the kidney and whether quality of life is improved for patients. Participation in ARMOR may involve retrospective data collection only, combined retrospective and prospective data collection, or prospective data collection
The purpose of this research study is to compare the effects on kidney function after performing the removal of a kidney tumor with or without clamping the blood vessels during surgery.
will scientifically evaluate whether Low Dose Naltrexone (LDN) has activity in refractory solid tumors within the context of a phase II clinical study
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 purpose of this study is to determine if a medication called mannitol, can help the kidney maintain its function after kidney surgery. Mannitol is used to cause an increase in urine production (it is a diuretic). For many years, mannitol has been given to patients in the hope it would improve the kidney's circulation, and in doing so reduce the impact of the surgery on the kidney. Mannitol is given during the surgery before the blood supply to the kidney is stopped. The blood supply to the kidney is stopped in order to minimize any blood loss during the removal of the tumor, and also to assist the surgeons view of the kidney anatomy. Once the tumor is removed the blood supply to the kidney is resumed. Sometimes a side effect of this temporary reduction in blood supply to the kidney is the loss of some kidney function. This may happen either in the short term (right away) or long term (months or years later). In studies done on animals, mannitol was able to lessen this damage to kidney function. However, no human study has ever confirmed that mannitol has the same helpful effect in humans. There is some suggestion that it may have no effect. Because sufficient research has yet to be done on humans, many surgeons do not give mannitol. A recent study, conducted at Memorial Sloan Kettering which looked back at patients who had undergone partial nephrectomies, an operation where only the portion of the kidney that contains the tumor is removed and enables the normal, unaffected portion of the kidney to be preserved. The results of this study demonstrated no significant difference in kidney function when the investigators compared patients who were given mannitol to those who were not. The investigators hope that this study will help clarify the effectiveness or not of mannitol on kidney function. During the surgery to remove the kidney tumor, patients will receive either mannitol or a placebo. A placebo, is a harmless medication that has no effects. The impact of mannitol compared to the placebo will be assessed by routine blood tests and imaging (kidney scan) 6 months after your surgery.
Usually, doctors monitor kidney cancer with CT scans to measure the size of tumors. Sometimes, even when a drug is working, it can take several months before the effects are seen on a regular CT scan. The purpose of this study is to see if a new kind of scan, called 124I-cG250 PET/CT, can determine response to sunitinib or pazopanib earlier than a regular CT scan. Research has shown that certain proteins in the blood, called antibodies, can attach themselves to cancer cells without binding to normal cells. In this study, an antibody is used called chimeric G250 (cG250) that is attached to a radioactive isotope. The radioactive isotope in this study is Iodine-124 (124I). If cG250 has attached to tumors in the body, 124I shows up on the PET scan.
Vascular Targeted Photodynamic therapy (VTP) with the Vascular Occluding Agent (VOA) WST11, may offer an alternative, providing tumour destruction via a minimally invasive approach. In this investigation, the investigators plan to use the WST11 VTP procedure to treat a predetermined small renal tumour targets. Patients will be given a general anaesthetic, to ensure immobility, and prevent discomfort during treatment sessions. Treated patients will then undergo surgical resection of their tumours, and the accuracy and reliability of tissue death with VTP will be assessed histologically. The aim of this proof of concept study is to demonstrate whether this modality has potential for a clinical role in the treatment of oncological kidney disease, either as an alternative to surgery, or where surgery is not feasible.
This study tests a new medication for treatment of kidney cancer, called BEZ235. This medication works by blocking several mechanisms that the cancer needs to grow and survive. By blocking these mechanisms, the medication can thus suppress further growth of the cancer, possibly kill cancer cells. Older kidney cancer medications (such as temsirolimus [Torisel®] or everolimus [Afinitor®]) typically only block one mechanism in cancer cells, so the investigators think that BEZ235 may work even better against kidney cancer. The purpose of the first part of this study is to test the safety of giving BEZ235 at different doses. The investigators are trying to find a safe dose of BEZ235 and want to find out what effects, good and/or bad, it has on the patient and the cancer.
