Utility of the multitarget stool DNA test for detection of colorectal neoplasia. (December 2017) - Sweetser, Seth
Colorectal cancer (CRC) is an ideal target for screening because it and its precursor lesions are prevalent and can be detected at curable stages among asymptomatic persons. Different screening strategies have been shown to reduce CRC incidence and mortality; therefore, CRC screening is widely recommended. However, despite these demonstrated benefits, a large percentage of the population remains unscreened and efforts are underway in multiple countries to improve screening participation. The multitarget stool DNA test (MT-sDNA) is a new noninvasive option for CRC screening that is a now recommended as a primary CRC screening strategy in the updated guidelines by the US Preventive Services Task Force, American Cancer Society and National Comprehensive Cancer Network. MT-sDNA has high accuracy for detection of both CRC and polyps at the greatest risk of progression, and has potential to improve screening uptake and effectiveness. This review provides a summary of MT-sDNA performance for detection of colorectal neoplasia and a perspective on the value it adds to our screening tool kit.
