Abstract:
Objective:To investigate the safety,efficacy,and prognosis of high-dose melphalan in combination with autologous hematopoietic stem cell transplantation (ASCT) for the treatment of multiple myeloma (MM). Methods:The clinical data of 17 patients with newly diagnosed MM who underwent ASCT as first-line consolidation therapy at the Yijishan Hospital of Wannan Medical College from March 2020 to October 2022 were retrospectively analyzed. The safety,efficacy,and prognosis of this treatment approach were evaluated. Results:Of the 17 patients,10 were male and 7 were female,with a median age of 56 (45-64) years. The stem cell engraftment rate was 100％,with a median neutrophil engraftment time of+10 (9-12) days and a median platelet engraftment time of+12 (10-21) days. The incidence of oral mucositis and intestinal infection after transplantation was 100％,with 2 cases of pulmonary infection,1 case of urinary tract infection,1 case of skin infection,and 11 cases of transient elevation of serum amylase. After transplantation,13 patients achieved a complete response (CR) or better,and the CR rate showed an increasing trend compared to before transplantation (13/17 vs 8/17;P=0.078). The median follow-up time was 18 (6-36) months,and 15 patients survived without progression,1 patient experienced disease progression,and 1 patient died due to clinical relapse and abandonment of treatment. The 2-year overall survival (OS) rate and progression-free survival (PFS) rate were approximately 90.0％ and 83.9％,respectively. Conclusion:High-dose melphalan in combination with ASCT as first-line consolidation therapy for MM can enhance the depth of patient response,further improve therapeutic efficacy,and the transplant-related complications are controllable,making it a viable option worth promoting in clinical practice.
