In this study, we are trying to improve treatment of Favorable Histology Wilms Tumors (FHWT). Wilms Tumor is the most common type of kidney cancer in children, and FHWT is the most common subtype.
This study involves new treatments and some usual treatments for FHWT. We will use results of biology tests to make treatment decisions. We may also use the tumor’s early response to treatment to guide further therapy.
