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.
