@entity3969 occurs in 5-10 % of all cases of @entity3969 . The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous @entity5 appear within the first 5 years of the @entity5 . Associated @entity600 are more common in bilateral cases. @entity5 are a therapeutic challenge. We describe the case of an 11-year-old @entity1 with left @entity11122 . The diagnosis was metachronous relapse of @entity3969 7 years after the first diagnosis. The @entity1 received five courses of preoperative chemotherapy and tumorectomy was performed. Because of post-surgical complications, nephrectomy was performed on her only kidney. Since she is anephric, the @entity1 is in @entity177 and is dependent on dialysis. Treatment with @entity3003 and @entity2879 was continued after surgery and the @entity1 is currently in complete remission. The appearance of a @entity3969 5 years after that of the @entity5 is rare. When a @entity5 develops, chemotherapy must be given until the size of the @entity5 is reduced in order to preserve renal function and avoid dialysis. In @entity1 with @entity177 caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.
