  • Publication number: 20220211876
    Abstract: Provided is a method for detecting a lesion characterized by administering to an organ a cell staining agent that enables observation of biological tissue by laser irradiation, and then irradiating the organ with multiphoton laser or confocal laser to image the inside of lesion in the organ, and determining the interface between normal site and lesion site.

  • Publication number: 20220022851
    Abstract: The present invention provides a method for determining the likelihood of colorectal cancer development in a human ulcerative colitis patient, the method including: a measurement step of measuring methylation rates of one or more CpG sites present in specific differentially methylated regions in DNA recovered from a biological sample collected from the human ulcerative colitis patient; and a determination step of determining the likelihood of colorectal cancer development in the human ulcerative colitis patient based on average methylation rates of the differentially methylated regions which are calculated based on the methylation rates measured in the measurement step and a preset reference value or a preset multivariate discrimination expression, in which the reference value is a value for identifying a cancerous ulcerative colitis patient and a non-cancerous ulcerative colitis patient, which is set for the methylation rate of each differentially methylated region, and the multivariate discrimination expres

  • Patent number: 11140318
    Abstract: The present invention is provided with an imaging unit (10) that has an imaging head (11) to be inserted into the digestive tract (112) and images a living body by applying a laser to the digestive tract (112) via the imaging head (11); a control unit (50) for controlling the imaging head (11) to move inside the digestive tract (112); and an image processing unit (70) for processing an image captured by the imaging unit (10). The imaging unit (10) captures a plurality of imaging regions (P) to be imaged along with the movement of the imaging head (11) such that a portion of adjacent imaging regions (P1, P2) overlap, and the image processing unit (70) overlaps regions (Pa) in which the plurality of imaging regions (P1, P2) are overlapped to generate a composite image.

  • Publication number: 20190352721
    Abstract: The present invention provides a method for determining the likelihood of sporadic colorectal cancer development, the method including: a measurement step of measuring methylation rates of one or more CpG sites present in specific differentially methylated regions, in DNA recovered from a biological sample collected from a human subject; and a determination step of determining the likelihood of sporadic colorectal cancer development in the human subject, based on average methylation rates of the differentially methylated regions which are calculated based on the methylation rates measured and a preset reference value or a preset multivariate discrimination expression, in which the reference value is a value for identifying a sporadic colorectal cancer patient and a non-sporadic colorectal cancer patient, which is set for the average methylation rate of each differentially methylated region, and the multivariate discrimination expression includes, as variables, average methylation rates of one or more differen

  • Patent number: 9868992
    Abstract: Methods and compositions for the diagnosis, prognosis and classification of cancer, especially colorectal cancer, are provided. For example, in certain aspects methods for cancer prognosis using expression or methylation analysis of selected biomarkers are described. Particular aspects of the present invention may include methods and biomarkers for diagnosing or detecting colorectal cancer or metastasis in a subject by measuring a level of expression of biomarker miRNA such as miR-885-5p in the sample from the subject and evaluating the risk of developing cancer or metastasis in the subject.
