概括
便免疫化学测试 (FIT) 显示了更多的查检测的结直肠癌 (CRCs),而不是瓜亚便隐性血液测试 (gFOBT). 降低便血红蛋白 (f-Hb) 值可以减少间隔癌症 (ICs),特别是在女性中.
科学领域:
- 胃肠病学 胃肠病学
- 公共卫生 公共卫生
- 癌症查 癌症查
背景情况:
- 苏格兰肠道查计划 (SBoSP) 从瓜亚便隐性血液测试 (gFOBT) 过渡到便免疫化学测试 (FIT).
- 间隔癌症 (ICs) 代表了在查插曲之间诊断的癌症,是查计划有效性的关键指标.
研究的目的:
- 为了比较基于FIT和gFOBT的SBoSP之间的间隔癌症比例 (ICP).
- 调查ICs与便血红蛋白 (f-Hb) 值,性别,年龄,剥夺,地点和阶段之间的关联.
主要方法:
- 一项前性队列研究,比较了基于FIT的SBoSP第一年的ICP数据和基于gFOBT的SBoSP第二年.
- 对查检测癌症 (SDCs),ICs,遗漏癌症和在不完全查后诊断的癌症的分析.
主要成果:
- 与IC相比,FIT显示SDC的比例明显高于gFOBT. 与IC相比,SDC的比例明显高于gFOBT.
- 在这两项测试中,女性的ICP显著高于男性.
- 提高f-Hb值增加了ICP;女性与男性相比,可比性ICP需要较低的值.
- 在基于FIT的SBoSP中,第一阶段的SDC数量超过了IC,而第四阶段的CRC更频繁的是IC而不是SDC.
结论:
- 降低f-Hb值对于减少间隔癌症至关重要.
- 实施性别特定的f-Hb值可以解决ICP的性别差异,但可能需要额外的结肠镜检查.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
