Abstract
[Problem] To provide a method for detecting high-risk prostate cancer, for the purpose of providing useful information, such as necessity of biopsy, to a test-positive patient in a PSA test. [Solution] The method for detecting high-risk prostate cancer according to the present invention comprises reacting a PSA contained in a sample composed of urine collected from a human body which is suspected to be suffering from prostate cancer with (1) a fucose α1→6 affinitive lectin which has a characteristic property that the lectin has affinity expressed by a binding constant of 1.0×10Mor more (at 25° C.) for an α1→6 fucose sugar chain No. 405. The fucose α1→6 affinitive lectin is preferably (2) a fucose α1→6 specific lectin which has a characteristic property that the lectin has a binding constant of 1.0×10Mor less (at 25° C.) for a sugar chain No. 003 that does not contain α1→6 fucose and a glycolipid-type sugar chain No. 909 that does not contain α1→6 fucose.
