We performed this study to evaluate the efficacy and liposomal doxorubicin （PLD, Ca of pegylated , vincristine, and reduced-dose dexamethasone combination therapy in newly diagnosed multiple myeloma （MM） patients in a Chinese population. METHODS This was an open-label, single-arm study in which newly diagnosed patients with MM received PLD 40 mg/m2 intravenously on Day 1, vincristine 1.4 mg/m2 intravenously （maximum 2 rag） on Day 1, and 40 mg of dexamethasone （intravenously or orally） from Day 1 to Day 4. Treatment was repeated every 28 days for at least 4 cycles. RESULTS In the intent-to-treat （ITT） analysis, the overall response rate was 68.29%, and the complete remission rate was 10.98%. The incidence of all adverse events was 46.34%. The most common non-hematologic toxicities were palmar-plantar erythrodysesthesia （13.4%） and stomatitis （6.1%）. CONCLUSION PLD, vincristine, and a reduceddose dexamethasone combination （DVd） is an effective and safe regimen in newly diagnosed MM patients in a Chinese population.展开更多
