This study analysed trends in polypoid colorectal cancer (PCRC) diagnosed by colonoscopy during the period 1995-2008 and compared the patterns observed in the years 2005-2008 with 1995-1998.
In the period 1995-2008, 24,245 colonoscopies were performed and 1041 patients with PCRC were diagnosed: pediculated (n = 220) or sessile (n = 821).
The mean age at diagnosis was 68.3 ± 11.6 years. Males were more likely to have PCRC (males 62.6%vs females 37.4%; P < 0.0001). Significantly more pediculated PCRCs were located in the distal colon (P < 0.001). In the 2005-2008 period the prevalence of PCRC among patients undergoing colonoscopy decreased, the number of polypectomies increased significantly (P < 0.0001) and the pediculated PCRC location changed, with a significant increase in right-sided lesions.
The prevalence of PCRC in patients undergoing colonoscopy decreased, with a significant increase in the number of polypectomies in the last decade. Pediculated PCRCs were more often located in the left colon and sessile PCRCs in the right colon. From the period 1995-1998 to 2005-2008 the location of pediculated PCRCs changed, with an increase in right-sided lesions.
本研究分析了 1995-2008 年结肠镜检查诊断的息肉状结直肠癌（PCRC）的趋势，并将 2005-2008 年观察到的模式与 1995-1998 年进行了比较。
在 1995-2008 年期间，进行了 24245 次结肠镜检查，诊断出 1041 例 PCRC 患者：有蒂（n=220）或无蒂（n=821）。
诊断时的平均年龄为 68.3±11.6 岁。男性更易患有 PCRC（男性 62.6%vs 女性 37.4%；P<0.0001）。有蒂 PCRC 更常位于远端结肠（P<0.001）。在 2005-2008 年期间，接受结肠镜检查的患者中 PCRC 的患病率下降，息肉切除术的数量显著增加（P<0.0001），有蒂 PCRC 的位置发生变化，右侧病变显著增加。
在过去十年中，接受结肠镜检查的患者中 PCRC 的患病率下降，息肉切除术的数量显著增加。有蒂 PCRC 更常位于左半结肠，而无蒂 PCRC 更常位于右半结肠。从 1995-1998 年到 2005-2008 年，有蒂 PCRC 的位置发生变化，右侧病变增加。
