Circulating tumor cells as predictive biomarkers in the risk stratification of DCIS: Evidence of early dissemination.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Overtreatment of patients with ductal carcinoma in situ (DCIS) is driven by a lack of a reliable prognostic biomarker. Widespread mammographic screening has resulted in a substantial increase in women diagnosed with DCIS. To improve patient risk stratification, we investigate circulating tumor cells (CTCs) as a biomarker for DCIS patients' biological aggressiveness and as an indicator of early dissemination. We apply microfluidics to enrich CTCs from 34 patients with DCIS and find a significantly higher concentration of CTCs compared to in healthy controls. We profile CTCs and matched DCIS tissues using single-cell RNA sequencing. We find that CTCs express higher clonal aberrations when compared to white blood cells from the same samples, and clonal comparisons between matched tissue and CTC samples provide evidence for an evolutionary bottleneck model. mRNA expression in CTC reveals EMT/MET and immunoregulatory pathway regulation with a suggestion of racial differences. Last, we provide support for early dissemination in DCIS using a Mouse IntraDuctal model.
