Eco-Evolutionary Guided Pathomic Analysis Detects Biomarkers to Predict Ductal Carcinoma In Situ Upstaging.
Article in Cancer research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Cancers evolve in a dynamic ecosystem. Thus, characterizing the ecological dynamics of cancer is crucial to understanding cancer evolution, which can lead to the discovery of biomarkers to predict disease progression. Ductal carcinoma in situ (DCIS) is an early-stage breast cancer characterized by abnormal epithelial cell growth confined within the milk ducts, and biomarkers are needed to predict which cases will progress to aggressive disease. In this study, we showed that ecological analysis of hypoxia and acidosis biomarkers can significantly improve prediction of DCIS upstaging. Quantitative analyses were performed on immunohistologic images from a retrospective cohort of DCIS specimens collected from biopsy samples. First, an eco-evolutionary designed approach was developed to define habitats in the tumor intraductal microenvironment based on oxygen diffusion distance. Then, cancer cells with metabolic phenotypes attributed to their habitats were identified, including a hypoxia-responding CA9+ phenotype and an acid-adapted LAMP2b+ phenotype. Whereas these markers have traditionally shown limited, if any, predictive capabilities for DCIS progression when analyzed from an ecological perspective, their power to differentiate between non-upstaged and upstaged DCIS increased significantly. Additionally, the distribution of distinct niches with specific spatial patterns of these biomarkers predicted patient upstaging. The niches were characterized by pattern analysis of both cellular and spatial features. A random forest classifier that was trained and underwent a five-fold validation on the biopsy cohort achieved an AUC of 0.74 for predicting clinical outcome. These results affirm the importance of tumor ecological features in eco-evolutionary-designed approaches for biomarker discovery. SIGNIFICANCE: Evolutionary dynamics of the various niches composing the tumor ecosystem can be harnessed for predicting cancer progression, demonstrating how eco-evolutionary-designed approaches can guide biomarkers discovery studies in the era of digital pathology. This article is part of a special series: Driving Cancer Discoveries with Computational Research, Data Science, and Machine Learning/AI.
