The clinical characteristics of 43 patients (pts) and the biological features of their non-stage 4 neuroblastoma (11, 3, 15, 7 and 7 with stages 1, 2A, 2B, 3 and 4S, respectively) all managed initially without cytotoxic therapy at Memorial Sloan-Kettering Cancer Center are summarised. We staged patients by the International Neuroblastoma Staging System and measured their urine and serum tumour markers. Tumour MYCN copy number, chromosomal ploidy, chromosome 1p deletion, Shimada histopathology, trk-A and CD44 expression were analysed. Among patients with localised tumour (n = 36), 13 had residual disease after initial surgery, 19 had regional lymph node invasion and 6 had epidural involvement (2 of 6 being paraplegic). All 7 stage 4S patients had liver tumours, 3 had bone marrow involvement and 3 had lymph node involvement. The most common adverse biological markers were unfavourable histopathology (9/40 evaluable tumours) and diploidy (7/39 tumours tested). At a median follow-up of 50+ months, 42 patients are alive and well (5 with evidence of disease), and 1 patient in remission died of encephalopathy. Progressive/recurrent disease occurred in 12 patients, 1 stage 2A, 2 stage 2B, 4 stage 3 and 5 stage 4S. Chemotherapy was eventually used in 4 patients: a 3-year-old stage 2B patient who developed stage 4; a 2-year-old whose recurrent tumour had poor-risk biological markers; a 1-year-old whose recurrent stage 3 disease infiltrated a vertebral body and a stage 4S infant with respiratory impairment from progressive hepatomegaly. Three of the treated patients had diploid tumours. We conclude that non-stage 4 is of itself a strong predictor of a favourable outcome. Diploidy, unfavourable histopathology and unresectable tumours were associated with disease progression. However, evolution of local-regional tumour into distant metastatic stage 4 disease is not typical of neuroblastoma.

Stage 4S metastatic neuroblastoma (NB) has a favorable prognosis due to a high rate of spontaneous regression. Young infants risk lethal complications arising from hepatomegaly, which can develop rapidly despite treatment. MYCN oncogene amplification confers a significantly worse prognosis. We describe a 4-week-old neonate with MYCN-amplified stage 4S NB complicated by gross hepatomegaly causing rapidly progressive respiratory, hepatic, and renal failure. The child remains in remission 3 years after hepatic artery embolization, radiotherapy, standard, and high-dose chemotherapy. Embolization of the hepatic artery, with classical treatment, is feasible and safe at this age and may contribute substantially to the management of high-risk patients.
