Abstract:

Objective

To explore the use of innovative non-invasive screening methods for colorectal cancer to improve the efficiency of colorectal cancer screening, and lay the foundation for early screening projects of colorectal cancer in China in future.

Methods

In the physical examination population of Harbin Medical University Cancer Hospital from 2016 to 2017, early screening of colorectal cancer based on multi-target fecal FIT-DNA combined detection technology was carried out, and the screening process and results are analyzed and summarized.

Results

A total of 594 subjects were performed with multi-target fecal FIT-DNA combined detection technique, of which 61 subjects were positive, with an overall positive rate of 10.27% (61/594). Among them, thirty-two subjects underwent colonoscopy, twenty-one subjects had abnormal colonoscopy results, ten subjects had no abnormalities in colonoscopy, and 1 subject had unknown colonoscopy results. The rate of colonoscopy abnormalities in males and females was 68.75% (18/29) and 100% (3/3). In addition, the sensitivity was 88.9% (24/27) and 42.8% (12/28) for confirmed colorectal cancer and adenoma, respectively.

Conclusion

Screening for colorectal cancer with multi-target fecal FIT-DNA combined detection technique in the physical examination population is economical and effective. In particular, non-invasive and convenient screening techniques can be used to improve colonoscopy compliance and detection rate.
