摘要
The role of autologous hematopoietic stem cell transplantation(auto-HSCT)following high-dose chemotherapy has been validated and accepted as a standard treatment for patients with relapsed diffuse large B-cell lymphoma(DLBCL).However,its clinical efficacy as frontline therapy remains to be elucidated.This study aimed to examine the feasibility of frontline auto-HSCT for newly diagnosed intermediate/high-risk DLBCL patients.We retrospectively reviewed the data of 223 patients treated with frontline auto-HSCT or chemotherapy alone(year 2008-2014)from four hospitals.The median follow-up time was 29.4 months.Between the two treatment arms among the intermediate/high-risk DLBCL patients,the 3-year overall survival(OS)and progression-free survival(PFS)rates of patients given frontline auto-HSCT were 87.6%and 81.9%,respectively,and the chemotherapy-alone group showed 3-year OS and PFS rates of 64.9%and 59.59%,respectively.Compared with the chemotherapy-alone group,the frontline auto-HSCT could eliminate the adverse impact of non-germinal center B-cell(GCB)type.In addition,in the frontline auto-HSCT group,patients who achieved complete response(CR)at auto-HSCT had a longer survival time than those who did not achieve CR.Our results suggested that frontline auto-HSCT could improve the prognosis of intennediate/high-risk DLBCL patients.
