摘要
目的探讨继发性骨髓纤维化(SMF)患者的临床及骨髓病理学特征。方法对69例SMF患者的临床表现、外周血涂片、骨髓涂片及骨髓活检情况进行回顾性分析,对不同疾病骨髓纤维化程度与巨核细胞数目进行相关性分析。结果69例SMF患者原发病分别为慢性粒细胞白血病(CML)20例(29.0%),淋巴瘤14例(203%),急性髓系白血病(AML)、骨髓增生异常综合征(MDS)各10例(14.5%),急性淋巴细胞白血病(ALL)6例(8.7%),多发性骨髓瘤(MM)4例(5.8%),骨髓增殖性肿瘤(MPN)3例(4.3%),慢性淋巴细胞白血病(CLL)2例(2.9%)。病理骨髓纤维化程度与巨核细胞数之间无相关性(r=0.024,P=0.848)。结论临床上多种血液系统疾病可以引起SMF。初诊的造血系统恶性疾病患者应同时行骨髓活检,特别是脾大、骨髓“干抽”的患者要考虑SMF的可能,骨髓病理学检查对临床诊断和鉴别诊断具有重要意义。
Objective To study the clinical features bone marrow biopsy of secondary myelofibrosis(SMF). Methods 69 patients with secondary myelofibrosis were analyzed retrospectively, and the relationship between myelofibrosis degree and megakaryocyte count was analyzed. Results Analysis of 69 cases of patients with SMF, the original incidence included 20 cases (29.0 %)of chronic myeloid leukemia (CML) , 14 (20.3 %) cases of lymphoma , 10 (14.5 %) cases of acute myeloid leukemia (AML), 10 (14.5 %) cases of myelodysplastic syndrome (MDS), 6 eases(8.7 %)of acute lymphoblastic leukemia (ALL) , 4 cases of multiple myeloma (MM) , 3 cases of myeloproliferative neoplasms (MPN) , 2 cases of chronic lymphocytic leukemia (CLL) . There was no significant difference of the mygakaryocytes" count and association of myelofibrosis with it was found (r=0.024,P=0.848). Conclusion Various clinical diseases of blood system may associated with secondary myelofibrosis. Bone marrow biopsy can be used to initial diagnostics of malignant disease of hematological system patients.When cellular examination of bone marrow is dry tap or dilution, which means higher incidence of SMF. Bone marrow biopsy plays an important role in diagnosis of SMF.
