Abstract
The present invention provides methods that are for acquiring various types of supplementary information used for diagnosis or treatment of prostate cancer, and that can be implemented in a less-invasive manner at a low cost. Provided are, by measuring the content of prostate specific antigen (PSA) having a β-N-acetylgalactosamine residue at a non-reducing terminal of a sugar chain in a specimen, and comparing the measured value with a threshold value, (1) a method for estimating whether a Gleason score (primary pattern and secondary pattern) is not less than or less than a prescribed value, (2) a method for estimating whether the pathological stage (pT) is not less than or less than a prescribed value, and (3) a method for acquiring information for assessment indicating diagnosis or treatment should be actively conducted because a GS at gross total removal is expected to be higher than a GS at biopsy.
