Outline of Research at the Start

がんのリンパ行性転移が初発するセンチネルリンパ節(SN)の転移状態を、SN内部の非がん組織の免疫反応を可視化することにより、間接的に診断するsurrogate imaging技術を開発し、SN生検をも省略する低侵襲がん治療の確立を目指す。具体的には、核医学検査や高磁場MRI検査を活用して、がんに対する免疫反応により増加したBリンパ球からなるリンパ濾胞の増大や胚中心の形成をインビボで可視化する方法を検討する。

Outline of Final Research Achievements

In this study, we aimed to establish in vivo imaging methods to diagnose the metastatic status of sentinel lymph nodes and to predict the prognosis of patients, based on the findings of non- tumor areas inside sentinel lymph nodes. In non-clinical studies, we used mouse model with sentinel lymph nodes in their popliteal regions. In mice with positive sentinel lymph nodes, lymph follicles appeared in non-tumor areas of sentinel lymph nodes at early stages and these follicles were suspected by ex vivo high magnetic-field magnetic resonance imaging tests. However, they were not detected by in vivo MRI tests. In clinical studies, we investigated the appearance patterns of lymph follicles in sentinel lymph nodes and their clinical outcomes. However, no clear correlations were shown.

Academic Significance and Societal Importance of the Research Achievements

本研究課題では、センチネルリンパ節内の主として非癌部所見からセンチネルリンパ節の転移状態およびがん患者の予後を予測するためのin vivo画像診断技術の確立を目指し、非臨床的および臨床的な検討を進めたが、現状では、センチネルリンパ節内の転移診断に主眼を置いた場合には、in vivoイメージング検査では、センチネルリンパ節の転移状態の診断を確実に行うことは難しく、当面はセンチネルリンパ節生検の省略は難しいと考えられた。
