Abstract
The presence of circulating immune complexes (ICS) in freshly drawn sera of 67 children with neuroblastoma was studied by the Raji cell radioimmunoassay of Theofilopoulos et al. (J. Clin. Invest. 57: 169--182), with particular emphasis on the correlation of levels of ICS with stage of disease and changes attributable to treatment. There was a close correlation between amount of complexes and stage of disease and treatment. Levels of ICS increased as the stage of the disease advanced, and were significantly higher (P less than 0.005) in stage IV than in all other stages combined. When patients with stage IV disease were subdivided into "before," "during," and "after" treatment groups, there was a significant decrease in ICS levels as treatment progressed. Studies of complement and complement components did not give such a clear relationship. A significant decrease of hemolytic C1 values was found in patients with "active disease" compared to normal age-matched controls. Some high C3 levels, determined immunochemically, were associated with low hemolytic levels of C3, which were attributed to C3 cleavage detected by immunoelectrophoresis. Based on our survival data, ICS, which were significantly different in 20 patients now decreased when compared to those of other patients, are very valuable in the prognosis of neuroblastoma.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
