Outline of Final Research Achievements

In this study, we attempted to establish MRI-based molecular imaging methods for the diagnosis of high-grade serous carcinoma of the ovary for the appropriate treatment strategy.
In early-stage cases, we developed a high-resolution molecular imaging method using diffusion-weighted images with spatially selective excitation to verify whether it is possible to detect very small lesions, which are difficult to be depicted by conventional morphological diagnosis. In advanced cases, we evaluated the effectiveness of comprehensive molecular imaging by various parameter analysis, and examined its usefulness for personalized treatment strategies.

Academic Significance and Societal Importance of the Research Achievements

高異型度漿液性癌は最も多い卵巣癌の組織亜型であり、卵管に限局する微小な上皮内癌から腹腔内に多数の播種巣を伴う進行症例まで様々な病態を呈し、遺伝子変異の発現の有無や、原発巣と転移・播種巣で治療に対する異なる反応性を示すことも知られており、疾患単位・病変単位での個別化治療戦略に向けて、分子イメージングによる検討に適する疾患と考えられる。
今回の研究成果は、予後に直結する早期発見の可能性を高めるとともに、進行症例においてはパラメータをRadiogenomicsの手法による解析に応用することで、将来的にはテーラーメイドな治療戦略をたてうる可能性が示唆された。
