It has an excellent [[prognosis]], with 90% of patients living for more than five years after being diagnosed. == Treatment == In general, Wilms' tumor is curable. If the tumor is only in the kidney, it can be removed along with the whole kidney. This procedure is called a [[nephrectomy]]. During the operation, the surgeon checks if the other kidney has a tumor. If there are tumors in both kidneys, a piece of the tumor will be removed. After the surgery, the child is given some chemotherapy drugs like [[Dactinomycin]]. This drug is also known by its [[trade name]] '''Cosmegen'''. Both operation and [[chemotherapy]] are sometimes used.<ref>{{cite journal |author=Metzger ML, Dome JS |title=Current therapy for Wilms' tumor |journal=Oncologist |volume=10 |issue=10 |pages=815–26 |year=2005 |pmid=16314292 |doi=10.1634/theoncologist.10-10-815 |url=http://theoncologist.alphamedpress.org/cgi/content/full/10/10/815?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=wilms&searchid=1&FIRSTINDEX=0&resourcetype=HWCIT |access-date=2012-06-20 |archive-date=2010-12-08 |archive-url=https://web.archive.org/web/20101208081556/http://theoncologist.alphamedpress.org/cgi/content/full/10/10/815?maxtoshow=&HITS=10&hits=10&RESULTFO
