The present invention is directed to a method for diagnosing large intestinal cancer and/or polyp and a method for observing postoperative course or monitoring recurrence thereof, wherein each method includes detecting cystatin SN protein by use of an anti-cystatin SN antibody. The present invention is able to provide a kit for assaying cystatin SN, which can be used, in a simple manner, in a diagnosis performed prior to conventional barium enema examination and endoscopic examination which impose burdens on patients; as an indicator of metastasis and recurrence; and in the evaluation of therapeutic effects. The present invention provides a method for diagnosing or monitoring large intestinal cancer and/or polyp which can be performed in a simple manner, and thus can allow to design a new regimen rapidly. |
