Detaljeret beskrivelse
OBJECTIVES:
I. Determine the impact on overall survival of patients with non-MYCN neuroblastoma below 18 months of age as compared to neuroblastoma patients above 18 months of age.
OUTLINE:
Archived DNA samples are analyzed for segmental chromosome aberrations by multiplex ligation-dependent probe amplification (MLPA), a polymerase chain reaction (PCR)-based technique. The following genomic regions are being studied: 1p, 1q, 3p, 4p, 7q, 9p, 11q, and 17q, as are the copy numbers of MYCN, NAG, DDX1, and ALK genes.

Beskrivelse
Inclusion Criteria:
Samples from neuroblastoma patients who, according to risk stratification, did not receive cytotoxic treatment and did never receive chemotherapy and are in complete response (CR) OR patients who, according to risk stratification, did not receive cytotoxic treatment initially, but had a localized or a systemic (stage Ms or M) relapse with or without following chemotherapy
- Low-risk Children Oncology Group (COG) designation: no initial cytotoxic treatment, any stage, any age, any outcome
- DNA from untreated neuroblastoma tumor samples (from patients in the age group below and from patients in the age group above 1.5 years of age) available from the COG, Europe, Israel, and Japan
- No MYCN amplification
- No Schwann cell stroma-rich tumors
- No tumor cell content below 60%
- No DOT
- No patients diagnosed before 1997 and after 2005
- No lack of follow-up data
- See Disease Characteristics
- No initial cytotoxic treatment
