In total, 6040 cases for 4 years in Niigata city and 6412 cases for 3 years in Maki town were examined. As the result of these mass screening, multiple colorectal cancer and polyp were detected. The grand total with colorectal cancer was 7 cases (0.12%) in Niigata city and 17 cases (0.27%) in Maki town. In the fecal blood test, firstly Hemoccult slide was used in single day. But the false positive rate was high and 4 of false negative cases were encountered in this series. To avoid false positive and negative cases, we used immunological fecal blood test (Latex agglutination test and R-PHA test) with high sensitivity and specificity for human fecal occult blood from 1986. As the result, cases who must be received minute examination were decreased in rate below 5%. But we think that year after year examination should be necessary for unknown false negative rate.}, pages = {737--744}, title = {3) 早期発見のための大腸癌集団検診(シンポジウム 大腸癌をめぐる諸問題 : 早期発見と治療, 第429回新潟医学会)}, volume = {102}, year = {1988} }
