简要总结
RATIONALE: Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, etoposide, and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Isotretinoin may help neuroblastoma cells become more like normal cells, and grow and spread more slowly. Giving combination chemotherapy before surgery may make the tumor smaller and make it more likely that the tumor can be surgically removed. It is not yet known what is the minimal amount of chemotherapy needed to achieve sufficient tumor shrinkage to control intermediate risk neuroblastoma and prevent tumor recurrence or metastases.
PURPOSE: This phase III trial is designed to reduce therapy for patients with favorable biology intermediate risk neuroblastoma by decreasing the number of chemotherapy cycles administered and by allowing for up to 50% residual tumor volume for patients with localized disease.
详细描述
OBJECTIVES:
Primary
- Reduce therapy for patients with intermediate-risk neuroblastoma while maintaining a 3-year overall survival (OS) rate of ≥ 95% by using a response-based duration of therapy algorithm.
- Maintain an overall 3-year OS rate of ≥ 90% for patients within each group.
- Utilize loss of heterozygosity, prospectively, at 1p36 and 11q23 to refine risk-stratification and treatment assignment, allowing patients whose tumors lack these chromosomal abnormalities to receive a reduction in therapy, and compare the outcome with patients treated on COG-A3961.
- Reduce intensity of therapy for patients 365 to < 547 days (12-18 months) of age with stage 4 neuroblastoma and favorable biological features and maintain a 3-year event-free survival (EFS) rate consistent with that for patients < 1 year of age with stage 4 neuroblastoma treated on COG-A3961.
- Reduce intensity of therapy for patients 365 to < 547 days (12-18 months) of age with stage 3 MYCN-nonamplified but unfavorable histology neuroblastoma and maintain a 3-year EFS rate consistent with that for patients < 1 year of age with stage 3, MYCN-nonamplified, unfavorable histology neuroblastoma treated on COG-A3961.
- Reduce surgical morbidity for patients with stage 4S neuroblastoma by allowing for biopsy only, rather than complete surgical resection, of the primary tumor.
- Systematically study the outcome of patients with stage 4S neuroblastoma who are unable to undergo biopsy for biology-based risk assignment.
- Determine if the extent of surgical resection correlates with the maintenance of local control, EFS and/or OS rates, and surgical complication rate.
Secondary
- Determine the results of a standard retrieval approach for patients with residual disease after 8 courses of initial therapy.
- Determine the results of a standard retrieval approach for patients with progressive, nonmetastatic disease.
- Identify additional biological surrogate markers for disease relapse and/or metastatic progression.
- Describe the neurologic outcome of patients with paraspinal neuroblastoma primary tumors.
- Correlate surgical biopsy technique with adequacy of tissue acquisition for biologic studies and with complications associated with the biopsy procedure.
- Prospectively validate the prognostic ability of the International Neuroblastoma Risk Group image-defined risk factor system, and compare the institutional assessment of image-defined risk factors with that of central review.

研究组 & 干预措施
Non-intermediate risk enrolled on intermediate risk trial
The no treatment group assignment patients may have received some treatment on ANBL0531 but they were not evaluable on this study due to being non-intermediate risk and hence did not receive a treatment assignment on ANBL0531.
