目的分析免疫法粪便隐血试验(IFOBT)及化学法粪便隐血试验(CFOBT)对上下消化道癌的检出率。方法对20例上消化道癌和30例下消化道癌粪便标本进行两种方法的检测,以“+”、“-”报告结果。用SPSS 11.5统计软件进行分析,以P<0.05为差异有统计学意义。结果上消化道癌IFOBT和CFOBT的阳性检出率分别为25%,60%;P<0.05。CFOBT优于IFOBT。下消化道癌IFOBT和CFOBT的阳性检出率分别为83.33%,53.33%;P<0.05。IFOBT优于CFOBT。结论上消化道癌的筛检应首选CFOBT,而下消化道癌筛检应采用IFOBT。
Objective To analyze the detection rate of upper and lower gastrointestinal carcinomas by immune feces occult blood test (IFOBT) and chemical fecal occult blood test (CFOBT). Methods Twenty cases of upper digestive tract cancer and 30 cases of lower digestive tract cancer stool specimens were tested by two methods, and the results were reported as “+ ” and “- ”. SPSS 11.5 statistical software for analysis, P <0.05 was considered statistically significant. Results The positive rates of IFOBT and CFOBT in upper gastrointestinal cancer were 25% and 60%, respectively; P <0.05. CFOBT is better than IFOBT. The positive rates of IFOBT and CFOBT in lower gastrointestinal cancer were 83.33% and 53.33%, respectively; P <0.05. IFOBT is better than CFOBT. Conclusion Upper gastrointestinal cancer screening should be CFOBT preferred, while lower gastrointestinal cancer screening should be IFOBT.
