Long-Term Retrospective Analysis of Prognostic Factors in Patients with Newly Diagnosed Multiple Myeloma without Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To retrospectively analyze the cases of multiple myeloma treated with chemotherapeatic regimens based on thalidomide, and to investigate the factors affecting MM patients treated using chemotherapeutic regimens with or without bortezomib.@*METHODS@#The clinical, laboratorial and survival data of 200 patients with newly diagnosed MM from October 2007 to December 2015 were collected, and the correlation of clinical and laboratorial indicators with the clinical characteristics and prognosis of MM patients was analyzed by using χ test, COX regression analysis, Kaplan-Meier method and Log-rank test.@*RESULTS@#Multivariable analysis showed that age (≥65 years old), ISS staging (Ⅲ), complex karyotypes and no-complete remission were the independent prognostic factors for OS in bortezomib-treated group, while the β-MG (≥8.95 mg/L), no-complete remission were the independent prognostic factros for OS in traditional therapy group. In addition, the MPI-1 myeloma prognostic index 1, consisted of age, complex karyotypes and complete remission in bortezomib-treated group, and MPI-2 consisted of β-MG (≥8.95 mg/L), complex karyotypes, complete remission in traditional therapy group were suitable for evaluating the pregnosis of MM patients treated with regimens contiaining bortezomib and traditional chemotherapentic regimans.@*CONCLUSION@#The differences of prognostic factors exist in MM patients treated with different chemotherapeutic regimens, moreover, the patients with comples karyotypes and no-complete remisson have poor prognosis. The MPI as more simple and easy clinical parameter, may be come an useful and complemental method for evaluation of prognosis except ISS and R-ISS.
