ABSTRACT
BACKGROUND: Over the past years, ixazomib has been increasingly explored for the treatment of relapsed/refractory multiple myeloma (RRMM). However, its results are still contradictory. This study will explore the efficacy and safety of ixazomib for patients with RRMM. METHODS: A systematic records search of Cochrane Library, PUBMED, EMBASE, CINAHL, ACMD, PsycINFO, WANGFANG, and China National Knowledge Infrastructure will be carried out from their origin to March 31, 2020 with no limitations of language and publication status. Trials will be selected by titles/abstracts, and full manuscripts by 2 independent authors. Data collection will be carried out from eligible trials based on the previous designed criteria. Study quality will be checked using Cochrane risk of bias, and statistical analysis will be administered by RevMan 5.3 software. RESULTS: This study will summarize the current high-quality trials investigating the efficacy and safety of ixazomib for the treatment of patients with RRMM. CONCLUSION: The results of this study may provide convinced evidence on the evidence-based medicine level, and guidance for clinical practice and future studies. INPLASY REGISTRATION NUMBER: INPLASY202040027.

An analysis is carried out to evaluate the suitability of compounds for boron neutron capture therapy (BNCT). Suitable boron compounds are not necessarily those that show a high uptake ratio between tumor and healthy tissue. Compounds with lower uptake ratios, but higher concentrations in both healthy tissue and tumor, can be as effective in increasing the dose to the tumor over that of healthy tissue. In compound synthesis and evaluation, the parameters for optimization should therefore not be limited to the uptake ratio. A final assessment of the question whether and how well a given compound is suitable for BNCT can only be made after a study of its radiobiological effects on tissue. The analysis also illustrates the importance of beam quality in thermal and epithermal BNCT. An increase of adventitious radiation must be compensated by higher absolute tissue levels of a given boron compound and/or a higher uptake ratio, in order to arrive at the same dose differential between tumor and healthy tissue.
