Clinical study of bortezomib for treating multiple myeloma with renal impairment / 中国实验血液学杂志

ABSTRACT

This study was purposed to analyze the clinical characteristics of multiple myeloma (MM) patients with and without renal impairment (RI) and to investigate the effect of bortezomib (Bor) on MM with RI. Clinical data of 39 MM patients (15 cases with RI, 24 cases without RI) received treatment of Bor in department of hematology in our hospital from Jan 2007 to Aug 2011 were collect and analyzed in term of clinical characteristics, curative efficacy, outcome of renal impairment and toxic reaction associated to chemotherapy. The results showed that (1) the obvious difference of the disease type, the creatinine, uric acid, serum calcium and β2-microglobulin levels existed in patients with and without RI, while there were no significant difference in hemoglobin and globin levels; (2) there were no significant difference in overall reaction rate and overall survival rate between MM patients with and without RI, however the median survival time of patients without RI was longer than that of patients with RI; (3) the RI could be reversed after the treatment with Bor, and the effect was most obvious after the first cycle. 20% MM patients with RI had recovered from RI after the first cycle; and the recovery rate from RI got up to 38.4% after the second cycle. The decline of creatinine levels had no difference between MM patients with or without RI after the second cycle. (4) The adverse events included gastrointestinal symptoms, peripheral neuropathy, thrombocytopenia and infection. There was also no difference between the 2 groups. It is concluded that Bor-based regimens for the MM patients with RI are effective and safe, and the renal function would be reversed after 2 cycle of Bor-based regimen.
