Risk Stratification
- Neuroblastoma patients are risk stratified into a low risk group, an intermediate risk group, and a high risk group based on the tumor INSS stage, tumor grade the patient's age, and the molecular pathway involved.
- Low risk neuroblastoma groups include:
- Patients with stage 1 tumor irrespective of the age, grade, and molecular pathway.
- Patients with stage 2A/2B, irrespective of age, irrespective of grade, MYCN-NA molecular pathway
- Patients with Stage 4S, <365 days of age, favorable histology, DNA Index >1 , MYCN-NA molecular pathway
- Intermediate risk neuroblastoma groups include:
- Patients with stage 1 tumor irrespective of the age, grade, and molecular pathway.
