OBJECTIVES:
* To determine if a fluorine 18-fludeoxyglucose positron emission tomography scan, performed as early as day 30 after high-dose chemotherapy and autologous stem cell transplantation, may be useful in identifying patients with non-Hodgkin lymphoma who may benefit from early interventions, including reduced intensity stem cell transplantation or additional therapy, to preempt disease relapse and improve overall survival.
OUTLINE: Conventional imaging, biopsy, and clinical examination findings are reviewed to determine patient clinical outcome (e.g., complete remission, disease progression/relapse, or death related to the primary disease).
