Clinical staging distribution was as followings, stage 1 : 17 cases, stage 2 : 14 cases, stage 3 : 10 cases, stage 4 : 5 cases, stage 5 : 6 cases. Treatment protocol was decided by prescheduled regimens : regimen EE-4A ; 25 cases, DD-4A ; 9 cases, RTK ; 2 cases, CCSK ; 1 case. Pathological diagnosis was done owing to Japanese classification by Japanese association of Pathologists : nephroblastoma, 38 cases, MRTK ; 4 cases, CCSK 1 case.
