Circulating Tumor DNA in Breast Cancer: Diagnostic Insights From a Case Series.
Article in Cureus, 2026. 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
Circulating tumor DNA (ctDNA), the tumor-derived fraction of cell-free DNA, has emerged as a valuable biomarker for monitoring treatment response, detecting minimal residual disease (MRD), and identifying early cancer recurrence. While histologic tissue diagnosis remains the gold standard for confirming malignancy, guidelines from organizations such as the National Comprehensive Cancer Network (NCCN) and the European Society for Medical Oncology (ESMO) acknowledge that ctDNA may serve as a supplemental tool in rare instances where tissue is unobtainable. In such cases, results should be interpreted alongside clinical and radiologic findings, with tissue confirmation pursued whenever possible. This case series presents three distinct breast cancer cases in which ctDNA-based MRD detection was instrumental in identifying recurrence and guiding precision therapy based on actionable genomic alterations when biopsy was not feasible or inconclusive.
