Of the colon rectum cancer the screening test for early detection

摘要

(57) Abstract The long-chain aliphatic aldehyde which 12 - 20 contains thing, and the carbon atom which obtain the mucus sample of the colon rectum from the rectum of the patient, the fact that existence of the marker which is chosen from the group which consists of especially CH₃ (CH₂) ₁₄ CHO and CH₃ (CH₂) ₁₆ CHO, and its Plasma low gene join precursive material is detected is included, method of detection of tumor forming or the cancer the colon or the rectum. Desirably this manner, the thing which finds the tumor formation or the cancer of the colon or the rectum due to especially, and the treatment which treat the sample with the Schiff reagent in the sample approximately it occurs with 550 - 590nm on the basis of the coloration which is included. This manner, two sugar markers DGal (1 - 3) DGalNAc (1Thr/Ser) and the D galactose or/or does not need the step which adds the enzyme in order to detect the saccharide marker which contains the 2 acetamide 2 deoxy D galactose.
