Several studies document the importance of immunity in the host-tumor relationship in neuroblastoma patients, evidentiacing a correlation between clinical comprome and immune impairment. In this study we evaluated some aspects of cellular and humoral immune capacity in 50 neuroblastoma patients at onset. The aim of this investigation was to define, if any, the common immune pattern of these patients, and to evidence a possible correlation with prognosis. Immune tests performed were serum immunoglobulin quantitation, absolute value of total T and B lymphocytes, and lymphocyte reactivity to phytohemagglutinin (PHA), Concanavalin A (ConA), and Pokeweed mitogen (PWM). In patients with localized or regional disease, diminsihed values of lymphocytes were observed in 4/16 cases, a datum highly correlated to a poor final outcome (P <0.01). Mitogen response and serum immunoglobulin levels were frequently altered, but no prognostic value was evidenced. Thirty-one children with disseminated disease presented more frequent and extended abnormalities: No parameter was found to correlate with prognosis, except for an impaired PHA response that paradoxically assumed a favourable prognostic meaning. Our results suggest that only the total lymphocyte number can contribute to predict the survival ratio in patients with regional disease.
