Pediatric Hodgkin's and non-Hodgkin's lymphomas: a retrospective analysis at the Children's Hospital of New Orleans

Abstract

Lymphomas constitute 10-12% of childhood cancers and are the third most common childhood malignancy. A retrospective analysis of thirty-six patients from the tumor registry of Children's Hospital of New Orleans was conducted during the period from 1995-2000. Patients were divided based on patient and tumor characteristics with recurrence and survival data compared to the Surveillance, Epidemiology and End Results (SEER) data of the National Cancer Institute. There were 18 patients (51%) with Non-Hodgkin's Lymphoma (NHL) and 17 (49%) with Hodgkin's disease (HD). Our sample had a similar distribution compared to the national population cohort except for different gender distribution in our HD patients. Also, most of our patients (63%) presented with advanced disease (Stages III and IV). Seventeen percent had recurrence of disease and 80% achieved remission, of which two patients developed secondary leukemia. Overall mortality was 17%. The survival in patients with HD was 94% which is comparable if not slightly superior to the national data. In patients with NHL, survival was 72% which was marginally lower than the national results (80%), most likely due to more advanced disease. Increased awareness in the pediatric community of the signs and symptoms of childhood lymphoma should result in earlier diagnosis and improved survival.
