Abstract:
Background and purpose:Solitary plasmacytoma of bone(SBP) is a rare disease,reports releveant to this disease are rarely seen. The purpose of this study was to investigate the relation between the clinical features and the prognosis of solitary plasmacytoma of bone. Methods:We reviewed the data of 12 patients diagnosed with solitary plasmacytoma of bone from 1998 to 2007 in Peking University third hospital,the clinical features,treatment and prognosis of the patients were analyzed retrospectively. Results:The age ranged from 37-71 years(mean 49.6 years) ,the male/female ratio was 3 to 1. Immunophenotype analysis showed that 11(91.6%) cases were positive for CD79a,10(83.3%) positive forVS38C,and all negative for CD20. With 12 to 87 months follow-up(average 40?22 months) ,three cases(33%) developed to multiple myeloma,two of them died from infection,the median survival time was 73 months,the 3 year and 5 year survival rate were 90 percent and 75 percent respectively. Conclusion:Middle and old male are more likely to develop SP. The prognosis is good,but some of them can progress to multiple myeloma.
