  • Patent number: 10656058
    Abstract: The present invention relates to a material for aggregating blood cells, used in the preparation of a paraffin block for diagnosing circulating tumor cells (CTCs), and a method for preparing a paraffin block using the same, and more specifically, to a method for detecting CTCs present in the blood through blood sample collection in the preparation of a paraffin block from CTCs, which are present in a very small amount in the blood. The present invention is non-invasive and simple, and thus is very useful for the diagnosis of cancer recurrence and metastatic cancer and for prognosis prediction, and can be a remarkable breakthrough in cancer treatment through the analysis of the onset, metastasis and recurrence mechanisms of cancer.
    Type: Grant

    Date of Patent: May 19, 2020
    Assignee: NATIONAL CANCER CENTER
    Inventors: Hee Jin Chang, Sun Young Kim, Ji Yeon Baek, Hyun Yang Yeo
  • Patent number: 9640375
    Abstract: The present invention provides a method for determining low mass ions for diagnosing colorectal cancer by using a MALDI-TOF mass spectrometer to biostatistically analyze low mass ions, which are extracted from a biological sample, and a method for providing information for diagnosing colorectal cancer using same. The present inventions can provide a diagnostic method, which requires low cost and a short time for analysis, can analyze large areas, and which can provide superior and credible discriminations.
