To investigate the clinical manifestations pathologic features, treatment options and prognosis of patients with bone lymphoma.The clinical characteristics, pathologic features, treatment and prognosis of 34 BL patients diagnosed by histopathologic method or/and PET-CT and treated in first hospital of peking university from January 2004 to April 2018 were analyzed retrospectively.The median age of 34 BL patients was 56 years old, the male and female ratio was 1.43∶1 (24 /10). Among 34 patients, the patients with primary bone lymphoma(PBL) were 8 cases, the patients with secondary bone lymphoma(SBL) was 26 cases, the PBL and SBL ratio was 0.31∶1. Bone lymphoma lacks typical systemic symptoms, and its onset began mostly from bone pain and pathologic bone fracture. The most frequent pathological type of bone lymphoma in our study was diffuse large B-cell lymphoma (DLBCL), accounting for 55.88%. At present, the conventional treatment for bone lymphoma includes chemotherapy, or chemotherapy combined with radiotherapy and surgery, as well as hematopoietic stem cell transplantation. The average and median OS time of BL patients were 349 years and 3 years respectively, meanwhile the OS rate for three years and two years were 56.25% and 78.16%, respectively. Factors that affect survival of BL patients were PBL and SBL classification, pathological type, blood LDH level, and treatment methods.Bone lymphoma is usually concealed onset,an adequate and adequate combination therapy can improve the survival rate and transplantation therapy plays an important role. Primary bone lymphoma is rare, the prognosis of patients with primary bone lymphoma is good, whereas the prognosis of patients with secondary bone lymphoma is poor.真实世界骨淋巴瘤的病理特征、治疗选择与患者预后评估.探讨骨淋巴瘤的临床特点、病理特征、治疗方法和患者预后.回顾性分析北京大学第一医院2004年1月至2018年4月收治的34例骨淋巴瘤患者的临床特征、病理特点、治疗及预后.34例骨淋巴瘤患者的中位年龄为56 岁,男、女性别比例为1.43∶1。原发性骨髓瘤(PBL) 8例,继发性骨髓瘤(SBL) 26例,PBL与SBL之比为0.31∶1。PBL患者常无明显的全身症状,多因骨痛或病理性骨折起病。病理类型以DLBCL最多,占55.88%。目前骨淋巴瘤的治疗方法为化疗,或化疗辅以放疗或手术,有条件者行造血干细胞移植治疗。本研究中骨淋巴瘤患者平均生存期为3.49年,中位生存期为3年, 3年生存率为82.14%。影响生存期的因素有PBL和SBL分类、病理类型、血LDH水平和治疗方法.骨淋巴瘤起病隐匿,选择足量、充分的联合治疗手段可提高患者的生存率,原发性骨淋巴瘤少见且预后较好,继发性骨淋巴瘤预后差.
