ABSTRACT
Objective:To observe the efficacy of the serial treatment with autologous hematopoietic stem cell transplantation after bortezomib and dexamethasone-based triple chemotherapy regimen and followed by lenalidomide and intermittent intensive therapy in primary plasma cell leukemia.Methods:A retrospective analysis was made on the clinical data of one patient who was diagnosed as primary plasma cell leukemia with complex karyotype in April 2018 in Henan Cancer Hospital, and the relevant literature was reviewed.Results:The patient received multiple cycles of bortezomib and dexamethasone-based triple chemotherapy regimen, then received autologous hematopoietic stem cell transplantation, lenalidomide and intermittent intensive therapy. The patient eventually achieved complete remission and the progression-free survival time was 18 months until the day before the deadline for this article.Conclusion:The treatment with autologous hematopoietic stem cell transplantation after bortezomib and dexamethasone-based triple chemotherapy regimen and followed by lenalidomide and intermittent intensive therapy may improve the prognosis of patients with primary plasma cell leukemia and prolong the survival time.
ABSTRACT
The drugs used in myelodysplastic syndrome(MDS) are quite limited,and the prognosis of some types of MDS is worse.Recently,lenalidomide has gotten people' s attentions.Lenalidomide has been approved for the treatment of International Prognostic Scoring System (IPSS)-classified low-or intermediate-1-risk MDS associated with chromosome 5q31 deletion,with or without additional cytogenetic abnormalities.However,the mechanism of action of lenalidomide is still unclear.There are some research findings indicated that lenalidomide also has effect on others types of MDS,suggesting that it can be used more widely.The latest studies about efficacies of lenalidomide on MDS are reviewed in this article.
