Abstract.
Malignant tumours in the neonate are distinct pathologically, clinically, and therapeutically from those in older children or adults. Behaviour cannot be directly implied from the histological appearance, and risk stratification is therefore difficult and complex. We review 42 patients seen over a 20-year period. Neuroblastoma (NB) was the commonest tumour seen (11), but the soft-tissue sarcomas were the dominant group (14). The initial management was surgical when possible. Chemotherapy, despite appropriate dose reduction, had significant morbidity and mortality. Whilst the outcome for congenital fibrosarcoma was good (6/7, 86%), there were no survivors amongst 5 patients with rhabdomyosarcoma. In the absence of cytogenetic and biochemical markers, risk stratification amongst babies with NB was based upon INSS staging. Stage I disease was associated with a good prognosis, whilst stage IV disease was uniformly fatal. Stage IVs disease had only 50% early survival. Patients with renal tumours, whether nephroblastoma or mesoblastic nephroma, did well. Only patients with morphologically immature teratomas were included, amongst whom there are 2 of 7 (29%) known survivors, but 43% have been lost to follow-up and their status is unknown. These figures are consistent with other reports from Africa.
