Carcinoembryonic antigen (C.E.A.) was detected in the faeces of 5 out of 10 healthy volunteers, 12 out of 18 patients suffering from gastrointestinal cancer (including 10 out of 11 cases of colonic cancer), and 3 out of 13 patients suffering from non-neoplastic disease. It is suggested that C.E.A. may be present in small amounts in normal faeces but that in malignant conditions of the bowel the amount increases.
在10名健康志愿者中，有5人的粪便中检测到癌胚抗原（C.E.A.）；18名胃肠道癌症患者（包括11例结肠癌患者中的10例）中，有12人检测到；13名非肿瘤性疾病患者中，有3人检测到。这表明正常粪便中可能存在少量癌胚抗原，但在肠道恶性病变时其含量会增加。
