According to the conventional International<unk>  System (INSS), there are 6 stages of neuroblastoma based on the tumor size, lymph node involvement, and presence of metastasis. However, according to a newly proposed International Neuroblastoma Risk Group Staging System (INRGSS), there are four stages of neuroblastoma based on the extent of dissemination and image findings. Neuroblastoma patients are risk stratified according to the Children Oncology Group (COG) risk stratification system into a low risk group, an intermediate risk group, and a high risk group based on the tumor INSS stage, the patient's age, tumor grade, and the amplification of MYCN gene.
