The clinical value of HSP27 expression of bone marrow mononuclear cells in multiple myeloma / 重庆医学

ABSTRACT

Objective To investigate the relationship of HSP27 expression with treatment response ,remission rate ,prognosis in multiple myeloma(MM) patients .Methods Eighty‐six patients with MM first diagnosis and 27 relapse cases were collected re‐spectively .Control was defined as non‐hematological malignance .The MM patients divided into first diagnosis ,relapse conventional chemotherapy group and bortezomib group .HSP27 expression and protein level were measured on pre‐and post 1 ,2 and 3 treatment circles .Results The tendency of HSP expression and protein levelrelapse‐MM patients> first‐diagnosis MM patients> control . HSP27 expression and level in Ⅲ phase was higher than those in Ⅱ phase for first‐diagnosis MM patients .Bortizomib‐containing chemotherapy protocol showed more effectively decrease on HSP27 than chemotherapy treatment only .At post‐1 treatment circle , HSP271 and delayed the relapse time .Conclusion BMMNC‐HSP27 expression and protein level is associated with staging ,treatment response and prognosis in MM patients .
