摘      要：AIM： To investigate the distribution and frequency of advanced polyps over eight years. METHODS：6424 colonoscopies were reviewea aunng the study period 1998 to 2005. The study period was subdivided into period I ： 1998 to 2001 and period 11： 2002-2005. RESULTS： 1856 polyps （33% advanced polyps） and 328 CRCs were detected. The mean ages of the patients with advanced polyps and cancer were 69.2 ± 12.0 and 71.6± 13.8 years, respectively. Advanced polyps were mainly lerc sided （59.5%）. Advanced polyps were found in patients ≤60 years from 17.7% in period Ⅰto 26.3% in period Ⅱ（P 〈 0.05）, especially in male subjects ≤60 years （21.6% vs 31.6%, P 〈 0.05）. Advanced tubuloviUous polyps rose from 21.5% in period I to 29.5% in period Ⅱ （P 〈 0.05）. Whereas cancers in male patients ≤ 60 years were similar in both periods： 23.2% vs 16.5% （P 〉 0.05）. CONCLUSION： Advanced polyps increased significantly in the younger male group in the most recent period and there seems to be a shiE towards a proximal location.
