Efficacy of 27 patients with multiple myeloma / 白血病·淋巴瘤

ABSTRACT

Objective To evaluate the efficacy and safety of bortezomib-based chemotherapy and MPT regimen in the MM patients who were newly diagnosed or relapsed/refractory. Methods Twenty-seven MM patients were treated with bortezomib-based chemotherapy, median cycles3 (range 1-5 cycles). Other 30patients received MPT chemotherapy. EBMT and WHO criteria were used to evaluate the therapeutic effects and the adverse effects, respectively. Results Bortezomib group 21 patients (77.8 %) showed effects after the first cycle chemotherapy and 24 patients (88.8 %) showed effects after the whole therapy. In wich, 15 patients(94.0 %) and 9 patients (82.0 %) were newly diagnosed and relapsed/refractory, respectively. MPT group 15patients (50.0 %) showed effects after the whole therapy. In wich, 12 patients (44.0 %) were newly diagnosed.And the other 3 were relapsed/refractory patients. The ORR in Bortezomib group was better than MPT group (P ＜0.05). The incidence of peripheral neuropathy, herpes and Ⅲ - Ⅳ grade thrombocytopenia in the bortezomib group was 10 patients (37.0 %), 7patients (26.0 %), 10 patients (37.0 %) respectively,and they were more common than MPT group, but the incidence of Ⅲ-Ⅳgrade anemia was 21 patients (70.0 %) and more comumom in the MPT group. The theraputic efficacy of bortezomib for renal insufficiency and normal renal function patients was similar, and no significant increase in all kinds of adverse effects. In MPT group,there were 4 patients with renal insufficiency, the serum level of creatinine in the 3 patients returned to normal after 5 cycles therapy. Conclusion Bortezomib-based chemotherapy is more effective than MPT regimen in the treatment of MM. The newly diagnosed, relapsed/ refractory and with renal insufficiency patients all can benefit from it. The adverse effects are mild and with better tolerance.
