背景与目的:肥胖被证实为增加结直肠癌的重要因素。有研究表明,无论对于男性还是女性,体质指数(body mass index,BMI)都与结肠癌的发病率有密切关系。因此,本研究探讨BMI与我国结肠癌发病的关系,为结肠癌的预防提供参考。方法:用病例-...背景与目的:肥胖被证实为增加结直肠癌的重要因素。有研究表明,无论对于男性还是女性,体质指数(body mass index,BMI)都与结肠癌的发病率有密切关系。因此,本研究探讨BMI与我国结肠癌发病的关系,为结肠癌的预防提供参考。方法:用病例-对照研究方法分析707例首次确诊的结肠癌患者和709名健康人的BMI情况,比较两组人群BMI的情况。结果:首次确诊的结肠癌患者平均BMI为(24.52±4.56)kg/m2,健康对照人群平均BMI为(23.75±3.14)kg/m2,结肠癌患者的BMI明显高于健康对照人群(t=-3.72,P<0.001)。根据性别和年龄的不同进行分组后,可以看出结肠癌患者的BMI比健康对照组高。logistic回归分析,BMI的升高是结肠癌发生的危险因素,OR值为1.059(95%CI,1.029～1.090)。结论:汉族人结肠癌的发生与BMI有关。展开更多

METHODS The reversed passive hemagglutination reaction fecal occult blood testing (RPHA FOBT) and colorectal cancer′s risk factor quantitative method as the preliminary screening, and 60 cm fiberoptic colonoscopy as the accurate screening were used to detect colorectal cancer in a natural community of 75813 subjects in this study. RESULTS As compared with the 60cm fiberoptic colonoscopy as a standard reference, FOBT has a sensitivity of 41 9%, specificity of 95 8%, Youden′s index 0 38, and positive predictive value of 0 68%, these results went up with age in the subjects from the first detection. A 3 year follow up in the target mass showed that all new cases were once FOBT negative. CONCLUSION Values in FOBT as an indicator of mass screening for colorectal cancer were limited.展开更多
