[Evaluation and Comparison of Thromboelastography and Conventional Coagulation Tests for Blood Coagulation Function in Children with Henoch-Schönlein Purpura].

OBJECTIVE

To investigate the efficacy of disease control, survival time and safely in treatment of newly diagnosed multiple mycloma patients with different dose of tenalidomide regimens.

METHODS

The clinical data of 116 patients with multiple myeloma from June 2011 to June 2015 were collected and analyzed retrospectively. According to doses of used lenalidomide based on dexamethasone plus lenalidomide regimen 116 patients were divided into 2 groups: conventional dose group (58 cases) and low dose group (58 cases). The ORR, PFS rate and OS rate during followed-up for 3 years, KPS score, RNS score and immunophenotypic index before and after treatment and drug toxicity incidence were compared between 2 groups.

RESULTS

The ORR for 2 treatment courses of low dose group was significantly lower than that in conventienal dose group (P＜0.05). The ORR for 4 and 6 treatment courses was not significantly different between 2 groups (P＞0.05). The PFS rate and OS rate during followed-up for 3 years was no significantly different between 2 groups (P＞0.05). The KPS score and RNS score after treatment of low dose group were significantly better than those in conventional dose group and before treatment (P＜0.05). The levels of immunophenotypic index after treatment of both groups were significantly better than those before treatment (P＜0.05). The incidence of III-IV grade hematological toxicity, pulmonary infection and herpes were not significantly different between 2 groups (P＞0.05). The incidence of peripheral neuropathy and gastrointestinal reactions in the low dose group were significantly lower than that in conventional dose group (P＜0.05).

CONCLUSION

Conventional and low doses of lenalidomide possess the same control effects and survival time for treatment of newly dingnosed patients with multiple myeloma; Despite, the initiation of effects from the low dose lenalidomide is relatively slower, it contributes to raise the overall quality of life and reduce the risk of drug toxicity.
