Heterogeneity of Disease Classified as Stage III in Wilms Tumor: A Report From the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP)

The worse outcome of the former may warrant a prospective study on the effects of intensified therapy. A subclassification of Stage III tumors is discussed.
