摘要在欧洲,结直肠癌居最常见癌症的第2位,其死亡率也占第2位。结直肠癌筛查可以降低死亡率,几个欧洲国家都制定了全国的筛查计划。在部分国家,结直肠癌的筛查几乎完全依靠粪便化验,内镜作为辅助手段。CT结肠成像(CTC)是一种有潜力的筛查检测手段,对检测≥10mm的早期肿瘤的敏感度约为88%。最近的一项随机化研究表明,CTC和结肠镜检查对早期肿瘤有相似的筛查检出率,表明CTC是一种有潜力的结肠肿瘤初筛检测手段。 Abstract In Europe, the second most common cancer of colorectal cancer ranks second in mortality. Colorectal cancer screening can reduce mortality, several European countries have developed a national screening plan. In some countries, screening for colorectal cancer depends almost entirely on stool tests and endoscopy as an adjunct. CT colonography (CTC) is a potential screening test and has a sensitivity of about 88% for detecting early tumors> 10 mm. A recent randomized study showed that CTC and colonoscopy have similar detection rates of early tumors, indicating that CTC is a potential screening test for colon tumors.
