A Review of Infants With Localized Neuroblastoma That Evolve to Stage 4s Disease.

The authors describe a newborn diagnosed with localized neuroblastoma that evolved to stage 4s at the age of 5 months. Peculiar features of the case included a bilateral adrenal primary, the skin as the only metastatic site, and the development of a muscular lesion late in the clinical course. The patient underwent left adrenalectomy and all other lesions regressed without further therapy. The case prompted a search for similar cases both in the Italian Neuroblastoma Registry and in the literature. All patients identified, although variously treated, survived with the exception of the 2 with MYCN gene amplification. We conclude that infants with neuroblastoma who undergo a transition from a localized to stage 4s disease could be less rare than expected. In the absence of unfavorable biology, a wait-and-see policy with strict follow-up could be adopted for these patients, avoiding potentially damaging systemic therapy.

Neuroblastoma in the adult: the Italian experience with 21 patients.

BACKGROUND: Neuroblastoma in the adult is rare. No established therapeutic guidelines exist for these patients and the literature on this issue is scant and contradictory. MATERIALS AND METHODS: Between 1986 and 2011, 21 adults (18 to 38 y; median, 23) diagnosed with neuroblastoma were referred to our hospital. Three of the 21 were classified as neuroblastoma, not otherwise specified, 13 as neuroblastoma, schwannian stroma-poor, and 5 as ganglioneuroblastoma, nodular. Nine patients had a resectable (stage 1/2) and 6 an unresectable primary tumor (stage 3); 6 had disseminated disease (stage 4). RESULTS: Of 9 stage 1/2 patients, 6 underwent surgery alone (2 survive, 4 died), 2 received adjuvant chemotherapy (both survive), and 1 received radiation therapy (alive). Four of the 6 stage 3 patients received chemotherapy and died, 1 underwent partial tumor resection only and died, and 1 received radiation therapy after partial tumor resection and is alive. The 6 stage 4 patients received chemotherapy with/without radiotherapy, and all died. Event-free survival at 10 years was 33.3% for stage 1/2, 16.7% for stage 3, and 0% for stage 4 patients. The 10-year overall and event-free survival rates were 39.8% and 19.1%, respectively. CONCLUSIONS: The outcome of neuroblastoma in adults is poorer than in younger patients at all stages. The clinical course seems modestly influenced by therapy.
