The authors have analysed 94 consecutive previously untreated children affected by NB diagnosed at the Giannina Gaslini Children's Hospital in the period January 1972 - December 1981. Age at diagnosis ranged between 1 month - 16 years (median 2 years). Diagnosis was made on histological grounds in 82 cases, on clinical, instrumental and laboratory data in the remaining 12 cases. Evans' staging system was adopted for classifying the disease extent. Patient recruitment was 9.4 cases for year. Female sex slightly prevailed in our series. 17 patients had localized disease (stage I and II), all surviving since 27 - 90 months. 28 children had regional disease (stage III) half of whom are presently alive. Five of the 47 cases with disseminated disease are alive at the time of this study; only one of these 5 can be considered cured, having been followed since more than 4 years. One of the two IV-s stage children survives disease-free at 89 months. 49% of patients were 2-year old or less at diagnosis while only 2 patients were older than 10. Survival was best in children diagnosed under one year of age, lowest in the 2 - 6 year age group. 74% of patients had their primary located in the abdomen (36 in the adrenal, 16 in sympathetic ganglia, 18 in un unidentifable site). Prognosis was worse in these patients compared with those with primary in the thorax, neck and pelvis. The clinical presentation of the disease has been extremely various: most patients had a diagnosis different from the definitive one, and were accordingly treated usually for several weeks or even months. Among laboratory data, urinary catecholamine metabolites, serum LDH and serum ferritin represented the most suitable indices of disease activity. Among immunological studies, none has shown a good correlation with the extent of the disease, nor with the clinical course. Stage I children had only surgery as treatment, while in stage II surgical ablation was followed by short-lasting chemotherapy and radiotherapy in few cases. In stage III and IV more complex multidisciplinary approach was utilized in the attempt to achieve a complete tumor regression. While about a half stage III cases appears curable by these treatment modalities, little impact has been demonstrated by this therapy in widespread disease, although the use of well-designed protocols seems have improved the complete remission rate and the median length of survival.
