The research team, led by Lee Min-young, senior researcher at the Advanced Bio and Healthcare Materials Research Division, and Park Sung-kyu, director of the Global Top Research Consortium, developed a new testing platform capable of detecting KRAS mutations, a key genetic driver of colorectal cancer, with very high sensitivity.

To test the technology, the researchers analyzed tumor tissue as well as matching blood and urine samples from patients with stage 0 and stage 1 colorectal cancer.

The results showed more than 90 percent agreement across the different sample types, suggesting that the method could serve as a reliable alternative to conventional tissue biopsies.
