内容紹介
高濃度乳房に対するマンモグラフィ(MG)による乳癌検診には限界があり、診断に苦慮する可能性がある。加えて、高濃度乳房は乳癌発症の高リスク因子の一つであるともされており、追加検査の必要性が研究されている。正常の乳腺組織と腫瘤との分界に関するMGの弱点を克服すべく超音波検査(US)、トモシンセシス、magnetic resonance imaging(MR)などが候補に挙がっている。それぞれの長所短所を俯瞰し、J-STARTが明らかにした日本におけるMGにUSを併用した場合の成績が私たちに教えてくれたものをあじわい理解したい。
Increased breast density can obscure subtle signs of malignancy on a mammogram. It may lead to delaying diagnosis. Moreover some evidence showed that increased breast density is associated with increased risk of breast cancer. Supplemental modalities include anatomic-based modalities (whole breast screening ultrasound (WBUS), handheld US (HHUS), digital breast tomosynthesis and functional modalities (magnetic resonance imaging (MR)). It is important to understand differences in the characteristics of these modalities. Overviewing past researches helps us to realize the significant results of J-START.
