Clinical Analysis of 25 Non-Transplanted Multiple Myeloma Patients Treated with Bortezomib Maintenance

Objective:To investigate the efficacy,survival and adverse effects of non-transplanted multiple myeloma(MM)patients treated with bortezomib maintenance.Methods:A total of 25 newly diagnosed/relapsed non-transplanted MM patients treated in West District of Beijing Chaoyang Hospital from June 2004 to November 2015 were analyzed retrospectively.All patients received PD regimen(bortezomib and dexamethasone),including bortezomib at a dose of 1.3 mg/m^2 and dexamethasone 20 mg on days 1,8,15,22 in a 3-month cycle.Results:Till November 1,2017,5 patients achieved stringent complete response(sCR),8 patients achieved complete response(CR),7 patients achieved very good partial response(VGPR),4 patients achieved partial reponse(PR),while 1 patient achieved stable disease(SD).After maintenance therapy,21 patients maintained the efficacy above PR,of which 1 patient was improved from CR to sCR;4 patients adjusted chemotherapy after disease progressed.Median maintenance therapy was 9 cycles(range from 6 to 31),and the median maintenance time was 27 months(range from 18 to 97).Median follow-up time was 73 months(range from 25 to 171).Median progress-free survival(PFS)time was 30 months(range from 9 to 105)and overall survival(OS)time was 57 months(range from 27 to 160).Till November 1,2019,3-year survival rate was 84%(21/25),and 5-year survival rate was 72%(13/18).The most common adverse events were transient leukopenia,thrombocytopenia and peripheral neuropathy,which the patients could tolerate after the prevention and treatment.Conclusion:Bortezomib-based maintenance therapy for non-transplanted MM patients can be an option in consideration of its safety and efficacy.
