 Colorectal cancer is the third greatest cause of cancer mortality, and the incidence of colorectal cancer in Japan is increasing gradually. To reduce colorectal cancer mortality, a higher compliance for colorectal cancer screening and follow-up programs is needed. Consequently, it is necessary to establish firm recommendations based on strong evidence from post-polypectomy colonoscopic surveillance. The Japan Polyp Study (JPS) began in 2000, and its objective is to evaluate follow-up surveillance strategies in patients who have undergone two complete colonoscopies for the control of colorectal cancer, with the removal of all detected polyps by high-resolution chromoendoscopy, including the removal of flat or superficial depressed (0-IIc) lesions. The JPS is scheduled to continue until the year 2010, and future data will help to develop recommendations for surveillance guidelines for such patients.
