Abstract: A cancer screening processor includes a database which stores a sample information database storing information on a number of dispensed samples of urine sent from subjects; the sample dispensed for a cancer type which the subject desire a screening, a center selection unit which selects an analysis center C2 for each of cancer type to be analyzed by using a urinary tumor marker; the analysis center C2 receiving a sample container including dispensed sample on the basis of the cancer type and information from analysis centers, and a processing unit which counts a number of the sample containers on the basis of the sample information database, and performs a process step of sending the sample container to the analysis center when the number of the sample containers becomes equal to a number in the information from the analysis center.

Abstract: A cancer screening device includes a cancer screening model generation unit configured to construct, as a cancer screening model, clinical data that is results of cancer screening for a plurality of subjects including cancer patients and healthy subjects, and metabolite exhaustive data that is a result of LC/MS analysis of first urine specimens collected from these subjects and is information related to amounts of a plurality of metabolites in the first urine specimens, a second acquisition unit configured to acquire sample data that is a result of LC/MS analysis of a second urine specimen collected from a second subject who is different from the first subjects, and a screening processing unit configured to estimate the cancer state of the second subject by applying an amount of metabolite in the sample data to the cancer screening model, and an output processing unit configured to output the estimated state of the cancer.

Abstract: A cancer analysis system includes, so as to perform an efficient image analysis in a cancer screening test using nematodes: a light source unit that irradiates a plate on which nematodes and a urine sample are plotted, from below; a photographing unit that takes an image of the plate irradiated by the light source unit; and an analyzer that analyzes the image taken by the photographing unit. The analyzer: couples a prescribed number of pixels in the image into a larger number of pixels thereof; and performs a chemotaxis assay of the nematodes based on a time variation of information on a luminous center of gravity of the image.

Abstract: In order to determine, in a cancer test using nematodes, whether or not the nematodes used in the cancer test are adequate, the present invention is characterized in that after a plate on which a urine from a subject and the nematode are set is placed, a cancer test apparatus performs imaging for quality assay of the nematode during the initial two minutes; an analysis apparatus determines a quality of the nematode using the imaging result; after taxis of the nematode is completed, the cancer test apparatus performs imaging for cancer test assay by the nematode; and the analysis apparatus determines the presence or absence of a cancer in the subject using the imaging result.
