  • Method for screening colon cancer cells and gene set used for examination of colon cancer
    Publication number: 20090011413
    Abstract: Colon cancer cells in a sample are screened by analyzing the amount of expression of at least 2 or more genes or products thereof selected from the group of genes listed in Tables 1 and 30. As compared to conventional method, patients having colon cancer can be detected with higher accuracy. Colon cancer cells in stool are also screened by analyzing expression of genes selected from the group of genes listed in Table 37.

  • METHOD AND APPARATUS FOR CELL RECOVERY
    Publication number: 20080145932
    Abstract: A method and apparatus for recovering cells from stool are provided for diagnosing colorectal cancer from stool naturally voided by multiple specimens. The method includes the steps of preparing a sample of naturally voided and collected stool, to which sample a buffer solution is added, causing cancer cells in the sample from which the impurities have been removed to be adsorbed on a solid carrier, and recovering the cancer cells thus adsorbed.

  • Container for suspension and filtration of stool
    Publication number: 20060122534
    Abstract: A container for the suspension and filtration of stool enables quick, simple, and safe collection of cancer cells separated in stool. The container comprises (a) a stool collection container 1, (c) a stool processing container main body 20, and (d) a pushing member 30. The stool collection container 1 comprises a syringe 2 capable of collecting 0.5 g or more of stool by being thrust into stool, a stool collecting opening, a handle 3 provided on the periphery of the syringe at the opposite end to the stool collecting opening, and a cap member 4 provided at the opposite end to the stool collecting opening.
