Circulating DNA is extracted from serum. PCR amplification of MYCN is performed and analyzed by agarose gel electrophoresis. Real-time quantitative PCR is also performed.

I. Perform in a blind study a multicentric study by analyzing serum from patients at diagnosis (with a known tumor v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog (MYCN) status determined in the Children's Oncology Group [COG] reference lab), in order to confirm our previous data and to define the most appropriate MYCN/control ratio cutoff capable of determining positive and negative cases.
II. Define the limits of the procedure in non-metastatic patients and in those with reduced tumor burden (International Neuroblastoma Staging System [INSS] stage 1 and 2).
Circulating DNA is extracted from serum. Polymerase chain reaction (PCR) amplification of MYCN is performed and analyzed by agarose gel electrophoresis. Real-time quantitative PCR is also performed.
