Common sites of neuroblastoma metastasis are which of the following?

b. Regional lymph nodes

c. Bone marrow

d. Cortical bone Liver

Neuroblastoma metastasizes to both regional lymph nodes and distant sites, most frequently bone marrow and/or cortical bone. The liver and lungs are rarely the site of metastatic spread. Cortical bone involvement as manifested by a positive bone scan is a particularly poor prognostic indicator. The majority of patients present with locally advanced disease at the time of diagnosis.
