Signatera™ MRD Test Predicted Overall Survival Benefit from Chemotherapy in Resected Metastatic Colorectal Cancer
Newly published study shows Signatera MRD-positive patients lived longer with adjuvant chemotherapy, while MRD-negative patients saw no significant benefit
First predictive data for overall survival from GALAXY trial in patients with oligo-metastatic CRC in the liver
Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, today announced the publication of new data in JAMA Oncology, evaluating the utility of Signatera, its personalized molecular residual disease (MRD) test, in patients with resected colorectal liver metastases (CRLM). The data was also presented as an oral presentation at the 2026 European Society for Medical Oncology Gastrointestinal (ESMO GI) Congress.
The liver is the most common site of distant metastasis in colorectal cancer, and CRLM is a major cause of cancer-related mortality.1,2 In patients where curative-intent surgery is possible, the benefit of adjuvant chemotherapy (ACT) has been a point of debate and uncertainty.3 MRD status has previously been shown to predict a disease free survival (DFS) benefit from ACT, but not an overall survival (OS) benefit. This is the first dataset in a large cohort to show MRD test prediction of OS from ACT in this population.
