    The COG study COG-AHEP0731 (Combination Chemotherapy in Treating Children With Newly Diagnosed Hepatoblastoma) incorporates the following risk groups:

    • Very low risk
      • Stage I tumor with pure fetal histology and an alpha-fetoprotein (AFP) level greater than 100 ng/ml.
    • Low risk
      • Stage I and II tumors and no small cell undifferentiated elements and an AFP level greater than 100 ng/ml.
    • Intermediate risk
      • Gross residual disease or unresectable disease.
      • Grossly resected disease with small cell undifferentiated elements.
      • No metastases.
      • AFP level must be greater than 100 ng/ml.
    • High risk
      • Any patient with metastases.
      • Any patient with initial AFP level less than 100 ng/ml, regardless of stage.
