Abstract:

Objective

To explore the effectiveness of a new mode of screening in colorectal ward in first-degree relatives of patients with colorectal neoplasms.

Methods

Colorectal cancer risk questionnaire, fecal immunochemical test (FIT) and multitarget stool DNA testing were used to detect first-degree relatives of colorectal cancer and advanced adenoma patients treated at the Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from October 2019 to July 2021. Based on the test results, screening risk stratification for first-degree relatives and recommended colonoscopy classification were performed, and their colonoscopy compliance rate and lesion detection rate were analyzed.

Results

A total of 250 subjects were included in this study. The colonoscopy compliance rate of the overall population was 38.0% (95/250), and the detection rate of colonoscopy lesions was 9.5% (9/95); the colonoscopy compliance rate of category A recommended population was 78.9% (15/19), the lesion detection rate was 26.7% (4/15); the colonoscopy compliance rate of category B recommended population was 61.2% (30/49), and the lesion detection rate was 16.7% (5/30); the colonoscopy compliance rate of the category C recommended population was 27.5% (50/182), and the lesion detection rate was 0 (0/50).

Conclusion

The combined use of the three screening methods can efficiently and accurately distinguish the screening risk of first-degree relatives. This program is an effective and feasible ward-based mode of opportunistic screening in first-degree relatives of patients with colorectal neoplasms.
