Role of preoperative circulating tumor DNA in predicting occult metastases in resectable and borderline resectable pancreatic ductal adenocarcinoma.
Article in World journal of gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundSome patients with resectable or borderline resectable pancreatic ductal adenocarcinoma (PDAC) may have distant metastases, undetected on preoperative imaging or early recurrence, within 6 months after surgery. Occult metastases (OMs) must be accurately predicted to optimize multidisciplinary treatment.
aimTo investigate the efficacy of circulating tumor DNA (ctDNA) in predicting OM.
methodsTwo Japanese institutions prospectively collected preoperative plasma samples from PDAC patients between July 2019 and September 2021 and evaluated ctDNA using a targeted next-generation sequencing panel covering 52 cancer-related genes.
resultsAmong 135 PDAC patients, 38 had OM and 35 were positive for ctDNA. The ctDNA positivity rate was significantly higher in patients with OM than in patients without OM. ctDNA-positive patients had significantly shorter median recurrence-free survival than ctDNA-negative patients. Logistic multivariate regression revealed ctDNA positivity as an independent predictor of OM.
conclusionPreoperative ctDNA in resectable PDAC is an independent predictor of OM and indicates poor prognosis following pancreatectomy and may be a useful biomarker in determining multidisciplinary patient care.
