A single, upfront genomic test is more effective for detecting Lynch syndrome in colorectal cancer (CRC) patients than the traditional multiple, sequential testing approach, according to new clinical data reported by The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
Researchers say offering this type of advanced genetic testing at the time of diagnosis could help guide and expedite treatment decisions for many patients who have CRC while simultaneously identifying the patients who are likely to have Lynch syndrome. This cancer-causing condition occurs when a person inherits a mutation in one of the DNA repair genes. Individuals with Lynch syndrome are much more likely to develop CRC, uterine, ovarian, stomach or other cancers than the general population.
For this study, researchers wanted to know if an upfront tumor-sequencing approach using a single test that screens for multiple mutations could replace the current multi-test screening approach commonly used to determine if a patient has Lynch syndrome.
To do this, researchers analyzed tumor samples from 419 CRC patients who participated in the
