Management and outcome of stage 3 neuroblastoma.

ABSTRACT:

Purpose

The management of patients with International Neuroblastoma Staging System (INSS) stage 3 neuroblastoma (NB) is not consistent worldwide. We describe a single centre approach at Memorial Sloan-Kettering Cancer Centre (MSKCC) from 1991 to 2007 that minimises therapy except for those patients with MYCN-amplified NB.

Methods

In this retrospective analysis of 69 patients, tumour MYCN was not amplified in 53 and amplified in 16. Event-free survival (EFS) and overall survival (OS) were determined by Kaplan-Meier analysis.

Results

Fourteen patients with non-MYCN-amplified tumours were treated with surgery alone (group A) and the remaining 39 (group B) with surgery following chemotherapy that was initiated and administered at non-MSKCC institutions. Chemotherapy was discontinued after surgery in 38/39 of the latter. The 10-year EFS and OS for all patients with MYCN-non-amplified NB were 74.9+/-16.9% and 92.6+/-5.5%, respectively. There was no difference in OS between groups A and B (p=0.2; 10-year OS for groups A and B was 84.6+/-14% and 97.1+/-2.9%, respectively). Patients with MYCN-amplified disease (group C) underwent dose-intensive induction, tumour resection and local radiotherapy: 13 achieved complete or very good partial remission, and 10 received myeloablative chemotherapy. 11/16 patients also received 3F8-based immunotherapy: 10 remain free of disease. The 10-year EFS and OS for patients with MYCN-amplified neuroblastoma treated with immunotherapy were both 90.9+/-8.7%.

Conclusion

Patients with MYCN-non-amplified stage 3 NB can be successfully treated with surgery without the need for radiotherapy or continuation of chemotherapy. Combination of dose-intensive chemotherapy, surgery, radiotherapy and immunotherapy was associated with a favourable outcome for most patients with MYCN-amplified stage 3 NB.

Project description:BackgroundThe survival rate among patients with intermediate-risk neuroblastoma who receive dose-intensive chemotherapy is excellent, but the survival rate among patients who receive reduced doses of chemotherapy for shorter periods of time is not known.MethodsWe conducted a prospective, phase 3, nonrandomized trial to determine whether a 3-year estimated overall survival of more than 90% could be maintained with reductions in the duration of therapy and drug doses, using a tumor biology-based therapy assignment. Eligible patients had newly diagnosed, intermediate-risk neuroblastoma without MYCN amplification; these patients included infants (<365 days of age) who had stage 3 or 4 disease, children (≥365 days of age) who had stage 3 tumors with favorable histopathological features, and infants who had stage 4S disease with a diploid DNA index or unfavorable histopathological features. Patients who had disease with favorable histopathological features and hyperdiploidy were assigned to four cycles of chemotherapy, and those with an incomplete response or either unfavorable feature were assigned to eight cycles.ResultsBetween 1997 and 2005, a total of 479 eligible patients were enrolled in this trial (270 patients with stage 3 disease, 178 with stage 4 disease, and 31 with stage 4S disease). A total of 323 patients had tumors with favorable biologic features, and 141 had tumors with unfavorable biologic features. Ploidy, but not histopathological features, was significantly predictive of the outcome. Severe adverse events without disease progression occurred in 10 patients (2.1%), including secondary leukemia (in 3 patients), death from infection (in 3 patients), and death at surgery (in 4 patients). The 3-year estimate (±SE) of overall survival for the entire group was 96±1%, with an overall survival rate of 98±1% among patients who had tumors with favorable biologic features and 93±2% among patients who had tumors with unfavorable biologic features.ConclusionsA very high rate of survival among patients with intermediate-risk neuroblastoma was achieved with a biologically based treatment assignment involving a substantially reduced duration of chemotherapy and reduced doses of chemotherapeutic agents as compared with the regimens used in earlier trials. These data provide support for further reduction in chemotherapy with more refined risk stratification. (Funded by the National Cancer Institute; ClinicalTrials.gov number, NCT00003093.)
