摘要 【目的】探讨粪便隐血试验、血清癌胚抗原与粪便SDC2基因甲基化检测在早期结直肠癌(CRC)筛查中的应用价值。【方法】选择2019年10月至2023年11月在本院进行健康体检的1936例志愿者作为研究对象,根据随机数字表法将其分为血清癌胚抗原检测组(n=624)、粪便隐血试验检测组(n=655)、粪便SDC2检测组(n=657)。其中任一项检查结果阳性建议患者接受电子结肠镜检查,以结肠镜+病理结果为金标准判定筛查结果。分别评估血清癌胚抗原、粪便隐血试验和粪便SDC2基因甲基化检测技术对CRC的筛查价值。【结果】1936例研究对象中有166例(8.57%)初筛阳性,其中血清癌胚抗原检测组49例(7.85%)初筛阳性,粪便隐血试验检测组60例(9.16%)初筛阳性,粪便SDC2检测组57例(8.68%)初筛阳性。血清癌胚抗原检测肠道病变的阳性预测值随着年龄的增加而升高,差异有统计学意义(P=0.033)。不同年龄及性别的粪便隐血试验检测肠道病变的阳性预测值、CRC阳性预测值和CRC及癌前病变阳性预测值比较,差异无统计学意义(P>0.05)。粪便SDC2检测CRC、CRC及癌前病变的阳性预测值随着年龄的增加而升高,差异有统计学意义(P=0.014、0.038)。【结论】粪便SDC2基因甲基化检测对所有肠道病变检出率和CRC检出率高于粪便隐血试验、血清癌胚抗原检测,粪便SDC2基因甲基化检测结合结肠镜检测可作为提高肠道病变检出率和CRC早期筛查的首选策略。

Abstract:【Objective】To explore the application value of fecal occult blood test, serum carcinoembryonic antigen, and fecal SDC2 gene methylation detection in early screening of colorectal cancer (CRC). 【Methods】A total of 1936 individuals who underwent health examinations in our hospital from October 2019 to November 2023 were selected as the research subjects. They were randomly divided into a serum carcinoembryonic antigen detection group (n=624), a fecal occult blood test detection group (n=655), and a fecal SDC2 detection group (n=657) using a random number table method. If any of the test results are positive, it is recommended that the patient undergo electronic colonoscopy examination, and the screening results will be judged based on the gold standard of colonoscopy and pathological results. The screening value of serum carcinoembryonic antigen, fecal occult blood test, and fecal SDC2 gene methylation detection technology for CRC was evaluated separately. 【Results】Among the 1936 study subjects, 166 cases (8.57%) were initially screened positive, including 49 cases (7.85%) in the serum carcinoembryonic antigen detection group, 60 cases (9.16%) in the fecal occult blood test group, and 57 cases (8.68%) in the fecal SDC2 detection group. The positive predictive value of serum carcinoembryonic antigen detection for intestinal lesions increases with age, and the difference is statistically significant (P=0.033). There was no statistically significant difference (P>0.05) in the positive predictive values of fecal occult blood tests for detecting intestinal lesions, CRC positive predictive values, and CRC and precancerous lesions among individuals of different ages and genders. The positive predictive values of fecal SDC2 detection for CRC, CRC, and precancerous lesions increased with age, and the differences were statistically significant (P=0.014, 0.038). 【Conclusion】Fecal SDC2 gene methylation detection has a higher detection rate and CRC detection rate for all intestinal lesions than fecal occult blood test and serum carcinoembryonic antigen detection. Fecal SDC2 gene methylation detection combined with colonoscopy detection can be the preferred strategy to improve the detection rate of intestinal lesions and early CRC screening.
