  • Patent number: 11435354
    Abstract: There is provided a simple and minimally invasive adenocarcinoma detection method. The adenocarcinoma detection method of the present invention includes a step of detecting in vitro a presence or absence of an abnormal cleavage in a specific protein in a test subject-derived sample.
