 目的　通过总结分析骨孤立性浆细胞瘤（SBP）的临床特点及治疗方法来提高其诊治水平。方法　回顾分析5家医院1999年至2009年收治的18例SBP的临床资料，对其临床特点及治疗疗效进行总结。结果　18例SBP患者年龄35～78岁，平均年龄54.2岁，男女比2.6∶1。通过随访治疗1～10年，采用化放疗治疗的10例患者有8例生存，2例死于进展为多发性骨髓瘤（MM），单纯化疗或单纯放疗的8例患者中有1例因化疗相关并发症死亡，2例死于进展为MM。全部患者目前共有11例处于持续缓解状态（CCS），2例因进展为MM在积极治疗中，平均CCS时间为47.3个月。结论　SBP是低度恶性肿瘤，化疗和放疗是其治疗的主要手段，化放疗相结合预后满意，部分患者可转化为MM。
