Natera, Inc. announced today the publication of a new study in the Journal of Clinical Oncology Precision Oncology that validates the use of its Signatera™ molecular residual disease test for monitoring recurrence and treatment response in early‑stage uterine cancer. The real‑world, multi‑center retrospective study analyzed 233 plasma samples from 61 patients with stage I/II disease who had undergone surgical staging, and found that ctDNA positivity identified 100% of recurrences before they were detected by imaging.
The study’s findings demonstrate that ctDNA positivity is more prognostic of recurrence than any traditional risk‑stratification factor used in clinical practice, and that it can predict recurrences prior to clinical diagnosis. This capability offers a personalized surveillance tool that could reduce unnecessary and toxic treatment in high‑risk patients, thereby improving patient outcomes and potentially lowering downstream healthcare costs.
By expanding the clinical evidence base for Signatera in a new indication, the study supports future reimbursement discussions, enhances Natera’s competitive differentiation in the oncology diagnostics market, and may drive increased adoption of the test in gynecologic oncology settings. The 100% detection rate and strong prognostic value underscore the technology’s clinical impact and position Natera to capture additional market share in the uterine cancer surveillance space.
