1 · What the graph read from 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.

2 · The registry

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

backgroundEndocrine resistance is a major clinical challenge in luminal breast cancer. Nuclear fibroblast growth factor 2 (FGF2) and altered progesterone receptor (PR) isoform ratios have been identified as markers of antiprogestin resistance. We investigated pathways associated with FGF2 upregulation to identify new targets for antiprogestin-resistant tumours.

methodsPR

resultsRNA-seq showed that FGF2 overexpression dysregulated Wnt signalling, downregulated oestrogen receptor (ER) and PR, and upregulated AR expression. PR isoform B (PRB) predominated, consistent with an antiprogestin-resistant phenotype. FGF2-overexpressing xenografts showed antiprogestin resistance, increased proliferation, and lung metastasis. AR and Wnt pathway blockade impaired tumour growth, and combined treatment further reduced tumour and metastatic burden. In clinical samples, nuclear FGF2 correlated with elevated AR levels in ER

conclusionWe identified a subset of luminal breast cancers characterised by nuclear FGF2, AR upregulation, and PR isoform imbalance. Dual AR and Wnt pathway targeting may offer a promising strategy for antiprogestin-resistant disease.
