 note = {Fecal occult blood testing has been performed for mass screening of colorectal cancer, in combination with gastric mass screening, in 3,730 persons in Niigata City for three years. The guaiac test (Hemoccult and Shionogi'B slide) was used in 1984 and 1985 and the immunological test (FECA-EIA) was used in 1986. 208 persons (5.6% in total subjects) were referred for barium enema or colonoscopy. These studies identified 4 cases (0.11%) with early colorectal cancer. In the Nishikanbara area, a total of 3,556 persons were screened for two years by using the guaiac test (Hemoccult slide) in 1985 and the immunological R-PHA test (Immedia-Hem Sp) in 1986. Colorectal cancers were detected in 7 cases (0.20%), three of these cancers being in an early stage. Thus this screening method is reliable for the detection of colorectal cancer in its curable stage.},
