Kidney Tumors

Pediatric kidney tumors fall into four primary categories: Wilms tumors (~85% of all cases), clear cell sarcomas of the kidney (~5%), congenital mesoblastic nephromas (~4%), and rhabdoid tumors of the kidney (~3%). The TARGET initiative is investigating three of these tumor types.



Kidney tumors are rare and generally curable in children. However, there are subsets of patients afflicted with these diseases that do not respond to treatment or eventually relapse. These patients usually have poor clinical outcomes as compared with the majority of children diagnosed with kidney tumors. All patients undergo therapy regimens that can be detrimental later in life. Through genome-wide characterization, TARGET investigators are identifying critical molecular alterations in these tumors, mostly from relapsed patients. Future research may identify treatments tailored to these alterations to improve outcomes for children afflicted with these kidney tumors.
