Outline of Annual Research Achievements |
前立腺特異抗原(prostate specific antigen:以下「PSA」と略記する。)は、分子量3万の糖タンパク質でアスパラギン結合型(N型)糖鎖を有することが知られている。我々は、独自のアプローチによって、PSAの糖鎖が癌性変異する(S2,3-PSA)ことを発見した。さらに、S2,3-PSAの遊離型PSAに占める割合を測定することにより、PSAの問題であった特異性(前立腺肥大症と前立腺癌の切り分け)が可能と考え、検討を行い、現行の前立腺癌のスクリーニング方法であるPSA値やF/T(%)PSA(フリーPSA(%))を指標とした診断法を遥かに凌ぐAUC = 0.8580というデータを得るに至った。同時に、表面プラズモン共鳴励起増強蛍光分光 (Surface Plasmon Field-Enhanced Fluorescence Spectroscopy, SPFS) 自動免疫測定装置を用いたレクチン-抗PSA抗体サンドイッチイムノアッセイ法により血清PSA分子上の糖鎖構造変異を定量分析するPSA-Gi検査法を開発してきた。1次スクリーニング対象血清検体718例の多施設(弘前大学、東北大学、McMaster大学(カナダ))後ろ向き検討でPSA-Gi検査の臨床的に重要な前立腺癌検出に関するAUCは、0.827であり、既存のPSA検査(AUC 0.712)、F/T PSA検査(AUC 0.661)よりも優位に癌特異性を改善し、前立腺針生検を約48%回避可能であることを示した。
