粪便脱落细胞学与粪隐血试验联合检测在结直肠癌诊断的临床意义

目的:通过分析粪便脱落细胞学与粪便隐血在结直肠癌发生、发展中的规律,进而评判粪便脱落细胞学与粪便隐血试验在结直肠癌诊断中的临床意义。方法:对243例患者粪便脱落细胞学与粪便隐血试验与癌胚抗原(CEA)的关系进行分析。结果:243例患者中,粪便隐血试验阳性率为79.5%;粪便脱落细胞学阳性率83.5%;CEA检出率为45.4%或52.9%。结论:粪便脱落细胞学与粪便隐血试验对结直肠癌的诊断有重要的临床意义,是结直肠癌筛检的重要手段,所以在临床应用中,采取两者互补的方法,可大大提高结直肠癌的检出率,且阳性率优于CEA。

The Clinical Significance of the Combined Test of Fecal Cytology and Fecal Occult Blood in the Colorectal Cancer Diagnosis

Objective:To evaluate the clinical significance of the combined test of fecal cytology and fecal occult blood in the colorectal cancer diagnosis through analysis to the law of the fecal cytology and fecal occult blood in the occurrence and development in colorectal cancer.Method:To analyze the relationship of fecal occult blood stool test and cytology and cancer embryonic antigen(CEA)through the study to 243cases of colorectal cancer patients.Results:The positive rate of fecal occult blood test was 79.5%,and the positive rate of fecal cytology was 83.5%,and the CEA positive rate was 45.4% or 52.9% in the 243patients.Conclusion:There is important clinical significance of fecal cytology and fecal occult blood test in the diagnosis of colorectal cancer and it is an important method of screening the colorectal cancer.So,the detection rate of colorectal cancer can be greatly improved by taking the complementary methods in clinical applications and the positive rate is better than CEA.
