Abstract
One hundred and eighty cases of neuro-blastomas from the four child oncology clinics are reviewed. The overall cure rate was 24%. During the 38-year period, there was a significant increase in survival from 0% during the period of 1943–1950 to 32% during the period of 1971–1980. This improved survival rate is most likely a result of adjuvant chemotherapy. Forty percent of the patients appear chronically ill, which reflects the fact that nearly 60% have metastases when they are first seen. In localized disease (stages I–II), the prognosis was favourable (cure rate 69%), while the prognosis for disseminated disease (stage III–IV) was poor (cure rate 5%). A favourable outcome was seen in patients under 1 year (survival rate 46%), and in patients with primary tumours located in the neck or mediastinum (survival rate 48%). When related to stage, however, the survival rates for the former tumours were not significantly better in patients below 1 year or in patients with cervical or thoracic tumours. As is the case in other studies, we found that survival is significantly poorer in males.
