Notizen:
To elucidate the development of bone metastasis in human neuroblastoma, bone marrow and bone metastases were analysed histologically in a hematogeneous metastasis model of murine neuroblastoma. The bone marrow metastasis occurred initially in the bone marrow sinusoid where tumor cells adhered and extravasated to bone marrow parenchyma, resulting in the formation of nodular lesions in the medullary cavity. The nodular lesions eventually progressed to diffuse lesions segmentally occupying the medullary cavity. During the establishment of the diffuse lesions, tumor cells invaded cancellous bone and/or bone cortex, resulting in bone metastasis. Such nodular or diffuse bone marrow metastatic lesions occurred sporadically in a variety of bones. To improve the results of treatment for neuroblastoma, the characteristics of the bone marrow and the bone metastases demonstrated in this study should be considered in the diagnosis and treatment of this disease.
