tumor cells (e.g., syncytia or immunocytologically-positive clumps of cells) and increased levels of serum catecholamines or urinary catecholamine metabolites as described above. The prognosis for patients with neuroblastoma is related to their age at diagnosis, clinical stage of disease, and (in patients older than 1 year) regional lymph node involvement. Other conventional prognostic variables include the site of the primary tumor and tumor histology . Cellular ClassificationOne clinicopathologic staging system involves evaluation of tumor specimens for the amount of stromal development, the degree of neuroblastic maturation, and the mitosis-karyorrhexis index of the neuroblastic cells. Favorable and unfavorable prognoses are defined on the bases of these histologic parameters and on patient age. The prognostic significance of this classification system, and of
