Response and Biology-Based Risk Factor-Guided Therapy in Treating Younger Patients with Non-high Risk Neuroblastoma

This phase III trial studies how well response and biology-based risk factor-guided therapy works in treating younger patients with non-high risk neuroblastoma. Sometimes a tumor may not need treatment until it progresses. In this case, observation may be sufficient. Measuring biomarkers in tumor cells may help plan when effective treatment is necessary and what the best treatment is. Response and biology-based risk factor-guided therapy may be effective in treating patients with non-high risk neuroblastoma and may help to avoid some of the risks and side effects related to standard treatment.

• Group A: patients < 12 months (< 365 days) of age with newly diagnosed INRG stage L1 neuroblastoma/ganglioneuroblastoma who meet the following criteria: * Greatest tumor diameter < 5 cm of adrenal or non-adrenal origin * Patients with non-adrenal primaries are eligible, but must have positive uptake on metaiodobenzylguanidine (MIBG) scan or elevated catecholamine metabolites (urine or serum) to support the diagnosis of neuroblastoma * No prior tumor resection or biopsy
• Group A will be further split into two subsets, which are mutually exclusive, for statistical purposes * Group A1: ** > 6 months and < 12 months of age with an adrenal primary tumor < 5 cm in greatest diameter OR ** Patients less than 6 months of age with an adrenal primary tumor > 3.1 and < 5 cm in greatest diameter OR ** < 12 months of age with a non-adrenal primary site < 5 cm in greatest diameter * Group A2: =< 6 months of age with an adrenal primary site and tumor =< 3.1 cm in greatest diameter.
• Group B: patients < 18 months (< 547 days) of age with newly diagnosed INRG stage L2 neuroblastoma/ganglioneuroblastoma who meet the following criteria: * No life threatening symptoms or no impending neurologic or other organ function compromise (e.g. epidural or intraspinal tumors with existing or impending neurologic impairment, periorbital or calvarial-based lesions with existing or impending cranial nerve impairment, anatomic or mechanical compromise of critical organ function by tumor [abdominal compartment syndrome, urinary obstruction, etc.]); horner syndrome is not considered neurologic compromise * No prior tumor resection, tumor biopsy ONLY * Only patients with both favorable histology and favorable genomic features will remain on study as part of Group B; the institution will be notified of histologic and genomic results within 3 weeks of specimen submission on ANBL00B1 or APEC14B1
• Group C: patients < 18 months (< 547 days) of age with newly diagnosed INRG stage Ms neuroblastoma/ganglioneuroblastoma
• No prior radiotherapy or chemotherapy, with the exception of dexamethasone, which is allowed
• All patients and/or their parents or legal guardians must sign a written informed consent
• All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met

Exclusion Criteria

• Patients with MYCN amplified tumors are not eligible
• Group B and C patients who do not enroll on ANBL1232 within 4 weeks of definitive diagnostic procedure
• Group A and C patients, not required to undergo tumor biopsy, who do not enroll on ANBL1232 within 4 weeks of confirmatory imaging study

PRIMARY OBJECTIVES:

I. To eliminate therapy as the initial approach for infants < 12 months of age with small International Neuroblastoma Risk Group (INRG) stage L1 neuroblastoma while maintaining an overall survival (OS) of 99%.

II. To eliminate therapy as the initial approach for non-high-risk patients < 18 months of age with localized neuroblastoma and favorable biology (histologic and genomic features) while maintaining an OS of 99%.

III. To achieve a 3-year OS of > 81% for infants < 18 months of age with INRG stage Ms neuroblastoma using objective criteria for early initiation of a response-based treatment algorithm.

EXPLORATORY OBJECTIVES:

I. To describe the time to intervention or tumor progression, type of intervention and site of progression for patients with localized neuroblastoma who experience progression after an initial period of observation.

II. To characterize the pharmacokinetic profile of the chemotherapeutic agents carboplatin and etoposide in patients with stage Ms disease.

III. To define the genomic profile of tumors from patients with non-high-risk neuroblastoma both at initial biopsy and at the time of subsequent biopsy or surgical resection.

IV. To describe the histology of tumor specimens obtained at the time of subsequent biopsy or surgical resection.

V. To determine the salvage rate (OS) of patients with tumor relapse or disease progression.

VI. To determine the procedural complication rate (initial biopsy, resection [intraoperative and postoperative], subsequent biopsy) and correlate with the degree of surgical resection.

VII. To determine the rate of reduction in image defined risk factors (IDRF) in L2 tumors following observation or chemotherapy.

OUTLINE: Patients are assigned to 1 of 3 treatment groups.

GROUP A: Patients undergo clinical observation for 96 weeks in the absence disease progression.

GROUP B: Patients undergo clinical observation for 3 years in the absence of disease progression. Upon disease progression, patients undergo surgery or receive first-line chemotherapy comprising carboplatin intravenously (IV) over 1 hour on day 1 (courses 1, 2, 4, 6, and 7), etoposide IV over 1 hour on days 1-3 (courses 1, 3, 4, 5, and 7), cyclophosphamide IV over 1 hour on day 1 (courses 2, 3, 5, 6, and 8), and doxorubicin hydrochloride IV over 15 minutes on day 1 (courses 2, 4, 6 and 8). Treatment with chemotherapy repeats every 21 days for 2-8 courses in the absence of disease progression or unacceptable toxicity. Once a partial response (PR) or better is achieved, patients undergo clinical observation for 3 years.

GROUP C: Patients at high risk for deterioration and a poor outcome immediately receive first-line chemotherapy as in Group B. All other patients undergo clinical observation for 3 years in the absence of disease progression. Upon disease progression, patients receive first-line chemotherapy as in Group B. Once a PR or better is achieved, patients undergo clinical observation for 3 years.

After completion of study treatment, patients are followed up annually for up to 10 years post-enrollment.
