KeywordsMultiple myeloma / lenalidomide / lipidomics / cfDNA
Outline of Final Research Achievements

This study aimed to elucidate factors related to sensitivity or resistance of lenalidomide and progression of multiple myeloma (MM) from the analysis of clinical samples, including bone marrow and peripheral blood. As a result, several gene mutations relevant to efficacy of lenalidomide treatment, other than CRBN, were identified from the analysis of circulating cfDNA. In addition, from the lipidomic analysis of serum, several metabolites were also identified. Further study is warranted to identify clinically available factors related to lenalidomide resistance and sensitivity of MM patients from the analysis of cfDNA and serum.

Academic Significance and Societal Importance of the Research Achievements

本研究により、末梢血cfDNAにおいて、骨髄中の腫瘍細胞の解析から同定しえなかった遺伝子変異を抽出でき、レナリドミド治療感受性との関連を同定しえたことは、今後の研究発展に大いに寄与する。また、本研究で行った末梢血血清の脂質メタボローム解析は、わが国が先行している斬新な研究手法であり、これまでのセレブロンおよびその関連因子とは違った新たな因子の関与を発見できるものと見込んでおり、実際に、複数個の脂肪酸およびリン脂質群が治療効果と相関があることを見出し、特定の脂肪酸とビタミン様作用物質が、免疫調節薬の効果に関わることを見出している。
