Perioperative ctDNA as a prognostic biomarker in endometrial cancer - the CODEC study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeBiomarkers to predict relapse and guide adjuvant therapy selection are needed in endometrial cancer (EC), one of the few cancers increasing in incidence and mortality. Assessment of circulating tumour DNA (ctDNA) at multiple perioperative time points has not been explored in EC. This study aimed to evaluate the prognostic utility of ctDNA across four perioperative time points, explore ctDNA dynamics, and compare ctDNA-derived tumour burden with 18F-fluorodeoxyglucose (FDG)-PET/CT and MRI. PATIENTS AND
methodsParticipants with Type 2 EC planned for surgery and consenting to the collection of biospecimens were enrolled prior to surgery and followed prospectively. Participants had preoperative imaging, and tumour sequencing was performed using hybrid capture, which guided the design of droplet digital PCR (ddPCR) assays for ctDNA analysis. The primary study endpoint was relapse free survival.
resultsFifty participants were enrolled in the CODEC study. Genomic findings were consistent with the established molecular landscape of EC. Detection of ctDNA postoperatively at 24 h (Time Point 2B) and at 2-6 weeks (Time Point 3) was associated with poorer relapse-free survival. No significant association with outcome was observed for preoperative (Time Point 1) or intraoperative (Time Point 2A) ctDNA. Preoperative ctDNA correlated with FDG-PET- and MRI-defined tumour volume.
conclusionThese findings are hypothesis-generating and support the prognostic relevance of postoperative ctDNA assessment in EC with the 2-6 week postoperative window the most clinically informative time point for detecting minimal residual disease. Further studies are required to validate these findings and determine whether ctDNA can guide adjuvant therapy selection.
