Diagnostic methods for the detection of cancer of the colon and rectum were compared and the best way to find cancer of the colon and rectum in its early stage was investigated. On the other hand, the relative survival rate was calculated and the long term prognosis of cancer of the colon and rectum was examined. The results are summarized as follows:<BR>1)So-called early cancer of the colon and rectum, of which invasion was limited to the mucosa and submucosa, can be correctly diagnosed before surgery and/or polypectomy when its diagnosis is made by the combined application of both biopsy and cytological examination under direct vision.<BR>2)Cancer of the colon and rectum can be cured when it is detected and resected in the stage of Dukes A, in which growth is limited to the wall of the colon and rectum without any metastasis.
