(57) [Summary] [Problem] Perform biopsy or surgical resection, Histochemical examination is performed on the resected stomach cancer tissue, and the results are used to determine whether or not cancer metastasis will become evident within 2-3 years after the operation. To provide a new method for estimating. SOLUTION: With respect to a sliced sample of a stomach cancer tissue which has been excised, the total number of cancer cells and the number of cancer cells exhibiting the binding ability to the dog haem agglutinin-derived leukocyte agglutinin are allowed to act on the sample, and the number of cancer cells showing the binding ability to the dog haem agglutinin-derived hemagglutinin is counted. However, in cancer cells, the content ratio of cells showing the ability to bind to dog cane bean-derived hemagglutinin is used as an index, and when the content ratio exceeds 40%, the frequency of occurrence of cancer metastasis after surgery is high. judge. |
