| [ Summary ] | Recently the numbers of colorectal cancer cases has been increasing in Japan. Immunological fecal occult blood tests (IFOBT) are useful for detecting colorectal cancer with mass screening. In our hospital, we have performed total colonoscopy (TCS) as a means of secondary examination for the IFOBT positive (FOBT group). Colorectal cancers in the FOBT group are detected earlier than those in patients with abdominal symptoms (the Sympton group). Advanced cancers in the IFOBT group were in the earlier stage, using the Dukes classification compared to those in the Symptom group. These data are compatible with several previous epidemiologic reports that mass screening, using FOBT, reduces mortality from colorectal cancer. In the present condition, the number of examinees checked with screening tests and secondary examinations is still low in the general population. In order to improve the efficacy of mass screening, it is important to increase the number of examinees. For that purpose it is nessesary to explain to the general population facts about colorectal cancer and the significance of screening examinations. Moreover, it is nessesary that we make an effort to refine techniques for and capacity of colonoscopic examinations. |
