Title: A Randomised Phase III Trial to Determine the Role of FDG-PET Imaging in Clinical Stages IA/IIA Hodgkin's Disease
Brief Summary: RATIONALE: A PET scan may help doctors learn how the cancer responded to combination chemotherapy and whether radiation therapy is also required.

PURPOSE: This randomized phase III trial is studying giving a PET scan to see how well it works in deciding whether patients who have received combination chemotherapy for stage IA or stage IIA Hodgkin lymphoma also need radiation therapy.
