Bortezomib/Liposomal doxorubicin (V-DD) is preferred to bortezomib single agent in salvage therapy for Multiple Myeloma (MM).

The present study is designed to assessment the efficacy and safety study of Bortezomib in combination with Liposomal Doxorubicin and Dexamethasone in treatment of Plasma Cell Leukemia (PCL).

Primary study endpoint is the overall response rate (sCR+CR+VGPR+PR). Secondary endpoints is the rate of complete response (sCR+CR), partial remission rate (VGPR + PR), duration of response (DOR), overall survival (OS).

Patient with Plasma Cell Leukemia(PCL ) and multiple myeloma (MM); KPS ≥ 60scores

Inclusion Criteria:

• Patients confirmed relapsed or refractory PCL who previously untreated or never received treatment with Bortezomib

• Alanine aminotransferase (ALT) ≤ 2.5 × the upper limit of normal (ULN)
• Aspartate aminotransferase (AST) ≤ 2.5 × the upper limit of normal (ULN)
• Cardiac function > Ⅲ grade and ejection fraction > 45%
• Signed informed consent prior to initiation of any study-related procedures that are not considered standard of care
