High-risk neuroblastoma in bone or bone marrow

High-risk neuroblastoma in bone or bone marrow refers to an aggressive, disseminated stage of neuroblastoma—an extracranial embryonal malignancy derived from primitive neural crest cells of the sympathetic nervous system Primarily affecting infants and young children, high-risk disease is typically defined by metastatic dissemination, advanced age at onset, or high-risk biological features such as *MYCN* gene amplification Clinically and pathophysiologically, osseous and marrow involvement refle...

High-risk neuroblastoma in bone or bone marrow refers to an aggressive, disseminated stage of neuroblastoma—an extracranial embryonal malignancy derived from primitive neural crest cells of the sympathetic nervous system Clinically and pathophysiologically, osseous and marrow involvement reflects advanced, hematogenous metastatic spread, which frequently manifests as persistent cytopenias, localized bone pain, pathological fractures, and refractory or relapsed clonal disease following intensive ...

High-risk neuroblastoma in bone or bone marrow refers to an aggressive, disseminated stage of neuroblastoma—an extracranial embryonal malignancy derived from primitive neural crest cells of the sympathetic nervous system—that has spread to or persisted within the skeletal system and hematopoietic compartment Clinically and pathophysiologically, osseous and marrow involvement reflects advanced, hematogenous metastatic spread, which frequently manifests as persistent cytopenias, localized bone pai...
