Once- versus twice-weekly Bortezomib induction therapy with dexamethasone in newly diagnosed multiple myeloma / 华中科技大学学报（医学）（英德文版）

In this study, we administered a modified schedule of weekly intravenous Bortezomib at 1.6 mg/m(2) with dexamethasone (BD) and compared it to the standard 1.3 mg/m(2) twice-weekly BD regimen in Chinese patients with newly diagnosed multiple myeloma (MM). We assessed the difference in efficacy, safety profile and survival between the once-weekly and twice-weekly cohorts (13 vs. 24 patients). The over response rate was similar with both arms of the study, being 77% in the once-weekly schedule and 74.9% in the twice-weekly schedule (P=0.690). The median overall survival was not reached in either schedule. Also, the median progression-free survival and duration of response of the once-weekly schedule did not significantly differ from those of the twice-weekly schedule (8 months vs.10 months, P=0.545 and 6 months vs.7 months, P=0.467 respectively). Peripheral sensory neuropathy and grade 3/4 hematologic toxic effects were more frequently reported in the twice-weekly schedule than the once-weekly schedule, but there was no statistically significant difference. This preliminary experience in Chinese patients with newly diagnosed MM indicated that once-weekly infusion of Bortezomib plus dexamethasone may improve safety without affecting outcome.

Hepatitis B virus reactivation in a chronic myeloid leukemia patient treated with imatinib mesylate / 中华医学杂志(英文版)

Imatinib mesylate is a molecular targeted agent for treating chronic myeloid leukemia (CML) and gastrointestinal stromal tumor. Although imatinib mesylate is not regarded as an immunosuppressive agent, few studies have also shown that it may impair immune response. In this report, we present a case of transient hepatitis B virus (HBV) reactivation during imatinib mesylate treatment for CML.
