粪便隐血试验

结论：粪便隐血试验对结直肠癌的诊断有重要的临床意义，仍然是结直肠癌筛检的重要手段，且阳性率优于CEA；

Conclusion : FOBT has important clinical significance in colorectal cancer diagnosis and is still an important method in colorectal tumor screening with a higher positive rate over CEA test .

方法：对382例结直肠癌患者粪便隐血试验与肉眼血便、癌胚抗原（CEA）、肿瘤部位、病理分型、肿瘤分期的关系进行分析。

Methods : The correlation of FOBT with gross blood stool , carcinoembryonic antigen ( CEA ), tumor site , histopathologic type and the stage of tumor was analyzed in 382 patients with colorectal cancer .

DukesA、B期患者的粪便隐血试验阳性率为78.5%，C、D期患者为81.9%（P>0.05），提示粪便隐血试验阳性率与大肠癌分期无关；

The positivity rate of fecal occult blood test ( FOBT ) in Dukes A + B cases was 78.5 % , and in Dukes C + D 81.9 % ( P > 0.05 ); There was no correlation between the positivity rate of FOBT and CRC stages ;

三种粪便隐血试验的比较研究

粪便隐血试验、乙状结肠镜、结肠镜和结肠气钡双重造影是筛查结直肠癌的主要手段。

这种依从性较低主要是由于传统粪便隐血试验需要饮食限制（使用愈创木脂法检测所必须的）以及收集粪便样本时候感官上不舒服。

This shortfall in compliance has been due mainly to dietary restrictions that are necessary with guaiac-based tests as well as for esthetic reasons associated with stool-specimen collection .

7603例受检者中试纸法粪便隐血试验的阳性率为12.9%（986例），应用我院自制的羊抗人血红蛋白抗体进行免疫法复检的阳性率仅为1.4%（108例）。

Of them 986 cases ( 12 . 9 % ) were positive for fecal occult blood by routine test and 108 ( 1.4 % ) were positive by immune reaction test ( with sheep anti-human hemoglobulin antibody developed in our hospital ) .

粪便DNA检测与粪便隐血试验用于普通风险人群结直肠癌筛检的比较

目的：通过分析粪便隐血在结直肠癌发生、发展中的规律，进而评判粪便隐血试验在结直肠癌诊断中的临床意义。

Objective : To investigate the clinical significance of fecal occult blood test ( FOBT ) in the diagnosis of colorectal cancer .
