Slight female predominance in unilateral cases; males are more frequently affected in bilateral cases.
Standard agents include Vincristine , Dactinomycin , and sometimes Doxorubicin . High-risk cases may require Cyclophosphamide or Etoposide.
The classic presentation of Wilms tumor is a in a young child aged <5 years. In one large cohort, an abdominal mass was the most common presenting feature (93% of patients).
