Filter by:Kidney transplantation is now the treatment of choice for end-stage renal disease (ESRD). Between 2800 and 3000 kidney transplants are performed each year in France and more than 33 000 patients are living with a functioning graft. Preventing allograft rejection requires the use of immunosuppressive therapy, the intensity decreases as the distance from the day of transplantation. Unfortunately, treatment favors certain complications, including infectious and neoplastic. These represent a major cause of mortality in these patients. If the frequency of skin cancer is greatly increased in this population, that of solid tumors remains a concern. Approximately 20% of patients develop cancer after 10 years of graft , half non- skin cancers, the main risk factor is immunosuppressive therapy . The aim of the study is to evaluate, in a large population of patients treated in 4 regions ( the Nord-Pas de Calais, the Upper and Lower Normandy and Picardy) risk factors (in particular the nature of the immunosuppressive treatment) of developing a neoplastic complication, skin cancers and solid tumors, after renal transplantation.
Partial nephrectomy (kidney removal) is a standard therapy for clinical T1 renal (kidney) tumors. The goals of surgery are to accurately remove the tumor with no cancer cells at the edge of the remaining tissue, to limit blood loss, and preserve kidney function. The most common technique is to clamp the blood supply to the entire kidney during removal and to surgically repair the tumor bed with suture and agents to stop bleeding. This stops the blood supply to the entire kidney including the healthy tissue, which can cause damage to the remaining tissue due to a shortage of oxygen if left clamped too long. This study uses a microwave pre-coagulation technique using the Certus 140™ to facilitate a bloodless area near the tumor for accurate tumor removal and repair, while avoiding clamping the blood supply, but its effect on the function of kidney adjacent to tumor is unknown. If adequate stoppage of bleeding is achieved using the Certus 140™ with minimal heat spreading to the remaining tissue, clamping and a shortage of oxygen can be avoided. The hypothesis is that microwave pre-coagulation is a safe method for providing the stoppage of bleeding during partial kidney removal.
The purpose of this study is to see if an antibody (cG250) attached to a radioactive substance (Iodine-124) safely detects clear cell renal cancer in patients with kidney tumors scheduled for surgery.
