ABSTRACT
<p><b>OBJECTIVE</b>To explore the efficacy and prognostic factors of induction therapy combined with autogenetic peripheral blood stem cells transplantation (APBSCT)in patients with multiple myeloma (MM).</p><p><b>METHODS</b>From January 1998 to May 2015, 201 patients with MM were enrolled. All patients received APBSCT after induction therapy. With the follow up to 20 June 2015, the overall survival (OS), progression free survival (PFS)and prognostic factor were analyzed.</p><p><b>RESULTS</b>① With a media follow up of 36.67 months, the median PFS and OS were 22.87 (17.48- 28.26)and 69.63 (63.57- 75.69)months, 5-year PFS and OS were 17% and 49%, respectively. ②After APBSCT, when the subgroup (n= 112) achieved complete response (CR)compared with the subgroup (n=89) not achieved CR, the median PFS were 32.93 (21.03-44.83) and 18.13 (14.46-21.80) months (P<0.001), respectively; And the media OS were 96.77 (71.79- 121.75)and 54.70 (49.53- 59.87) months (P=0.004), respectively. The risks for disease progression and death declined in CR subgroup. ③ Two subgroups included or not included bortezomib/thalidomide at induction therapy (123 patientsvs 21 patients), the media PFS were 31.67 (24.36- 38.98)and 15.20 (10.11- 20.29) months (P=0.013), respectively; And the media OS were 76.30 (55.44- 97.15)and 52.03 (33.76- 70.30) months (P=0.014), respectively. ④According to the ISS stage, the media OS of stageⅠ, Ⅱ, Ⅲ were 99.47 (59.58-139.36), 66.77 (52.17-81.37), 53.97 (28.71-79.23) (P< 0.001), respectively. The risk for death of stage Ⅱ, Ⅲ were 2.16 and 3.04 times higher than stage Ⅰ, with no difference in terms of PFS. ⑤ The media PFS in IgD (n=22) and IgG (n=101) type MM were 11.17 (10.27- 13.13)and 35.43 (22.69- 48.17)months (P=0.007) , respectively; The media OS were 30.83 (0.24-61.42)and 70.70 (53.52-87.88) months (P=0.039), respectively. The risk for disease progression of IgD type was 2.47 times higher than IgG type. ⑥ Patients received 1 line induction therapy (n=132) compared with more than 1 line (n=69), the media PFS were 25.43 (16.09- 34.77)and 20.27 (15.04- 25.50) months (P=0.042). ⑦Cox analysis showed that CR after APBSCT and ISS stage were independent prognostic factors for OS. IgD type MM and CR after APBSCT were independent prognosis factor for PFS.</p><p><b>CONCLUSION</b>CR after APBSCT and ISS stage were independent prognostic factors for OS in MM. CR after APBSCT was independent prognostic factor for PFS in MM. However, disease progression more likely occurred in IgD type MM, which was independent negative prognostic factor for PFS in MM.</p>

Autologous stem cell transplantation (ASCT) is the standard frontline therapy for newly diagnosed multiple myeloma (MM) in patients younger than 65 years in the era of conventional chemotherapy. The use of novel drug-based chemotherapy in the in-duction, consolidation, and maintenance phases of chemotherapy has significantly improved the response rates of patients. Thus, wheth-er or not ASCT is still necessary in the era of new drugs has become controversial. Currently available data supported that ASCT should be the frontline therapy for qualified newly diagnosed MM patients and that new drugs may be applied before and after ASCT to further improve the response rate and prolong the progression-free survival of patients. Further prospective clinical trials should be conducted to clarify the role of ASCT in MM and optimize the treatment strategies involving ASCT in the era of new drugsto cure myeiona.

ABSTRACT
According to the latest classification of International Myeloma Working Group(IMWG),multiple myeloma(MM)is roughly classified into two groups,asymptomatic myeloma(smoldering myeloma)and symptomatic myeloma.The former is equal to the stage Ⅰ of Durie-Salmon(DS),and patients of this type only wait and see,and do not need any therapy.The later is equal to stage Ⅱ and Ⅲ of DS,and patients of this type need therapy immediately.Autologous stem cell transplantation(ASCT)is recommended by National Comprehensive Cancer Network(NCCN)for patients with stage Ⅱ or Ⅲ myeloma with good performance status in 2007.Different therapeutic regiwen should he selected for newly diagnosed MM patients according to whether ASCT is suitable or not.
