Current status of research on bone marrow necrosis syndrome / 中国组织工程研究

ABSTRACT

BACKGROUND: Bone marrow necrosis has unspecific clinical features, which is often misdiagnosed or missed due to a lack of the knowledge of the disease. OBJECTIVE: To improve the awareness and vigilance to bone marrow necrosis, and to further explore the clinical manifestations, hematological characteristics, pathogenesis and treatment of bone marrow necrosis. METHODS: The bone marrow necrosis, hematologic neoplasms, solid tumor, bone marrow puncture, bone marrow pathology in Chinese and English served as the search terms to search articles related to bone marrow necrosis in PubMed and Wanfang databases, published from 1941 to 2016. Totally 43 articles were selected for review. RESULTS AND CONCLUSION: Bone marrow necrosis is a rare complication caused by various diseases, clinically characterized by bone pain, fever, anemia, and nucleated red cells and immature neutrophilic leukocytes in the blood smear. Bone marrow aspiration and/or bone marrow biopsy show(s) necrotic features. Its pathogenesis is complex, and it is still poorly understood and needs further research. There is no good treatment for bone marrow necrosis, and the prognosis is poor. Early correct diagnosis and etiological treatment are crucial for the prognosis of bone marrow necrosis.With the improvement of disease awareness, bone marrow cytology, genetics, MRI and hematopoietic stem cell transplantation, bone marrow necrosis is expected to get a better prognosis.
