Therapy for Pediatric Hodgkin Lymphoma

This study will evaluate the following objectives: Primary Objectives: 1. To evaluate the efficacy of 4 cycles of VAMP chemotherapy alone in patients with favorable risk Hodgkin's disease who achieve a complete response after 2 cycles of VAMP chemotherapy. 2. To evaluate the efficacy of 4 cycles VAMP chemotherapy plus low dose RT in patients with favorable risk Hodgkin's disease who achieve a partial response after 2 cycles of VAMP chemotherapy. 3. To evaluate the efficacy of 2 alternating cycles of VAMP/COP chemotherapy (total 4 cycles of chemotherapy) plus low-dose, involved-field RT in children with intermediate risk Hodgkin's disease. 4. To evaluate the efficacy of 12 weeks of Stanford V chemotherapy plus low-dose, involved-field RT in children with unfavorable risk Hodgkin's disease. Secondary Objectives: 1. To evaluate patient quality of life during and after treatment from the patient and parent perspective. 2. To compare patient and parental ratings of treatment-related symptoms and patient physical, psychological, social and cognitive functioning before the first treatment (T1 - baseline); after Cycle 2 or after 8 weeks of Stanford V (T2 - Evaluate Response); after cycle 4 or after 12 weeks of Stanford V and before or on the first day of radiation (as applicable) (T3); at the conclusion of radiation or within a few days following the end of radiation (as applicable) (T4); and at 3 to 6 months after completion of therapy follow-up evaluation (T5).
