What was measured

Endocrine dysfunction was assessed by growth hormone stimulation (GHS) tests. We report the percentage of patients with abnormal growth hormone stimulation tests.

Analysis population: Only eligible \& evaluable patients 3-7 years of age were included. Patients with anaplastic histology or disseminated/excess residual disease were not evaluable (NE). Availability of growth hormone stimulation test results were very limited. Only 3 out of 464 eligible and evaluable patients had this data available (2 PFRT patients and 1 IFRT).

Groups in this outcome

Involved Field Radiation (IFRT)

Includes eligible patients 3-21 years of age without anaplastic histology or evidence of disseminated or ERD based on central review and randomized to one of the IFRT arms (Treatment Arms I, III, V)

Posterior Fossa Radiation (PFRT)

Includes eligible patients 3-21 years of age without anaplastic histology or evidence of disseminated or ERD based on central review and randomized to one of the PFRT arms (Treatment Arms II, IV, VI)
