Topological analysis of the human lymph node reticular network predicts outcome in breast cancer.

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
Axillary LNs (ALNs) initiate immune responses in breast cancer (BC) but how and when ALNs become dysfunctional, facilitating metastasis, is unclear. The fibroblastic reticular cell (FRC) network within ALNs provides structural support and mediates immune homeostasis, but we have yet to elucidate whether this network changes during BC progression. An unbiased computational approach was used to quantify features of the immunolabelled FRC network in ALNs derived from patients with BC. Platelet-derived growth factor receptor β (PDGFRβ) was identified as a robust immunomarker for human FRC and used to quantify how FRC network topology changes during BC progression and after treatment. Formalin-fixed paraffin-embedded ALNs (n = 331) from 179 patients with BC and 23 benign reactive controls were assessed for FRC network metrics, including lacunarity and branchpoints, alongside de-identified clinico-pathological data. These data were then integrated using multivariate, principal component and survival analyses. In node-negative, post-neoadjuvant chemotherapy triple-negative BC, denser FRC networks in uninvolved nodes significantly improved survival (p = 0.0365). [Correction added on 09 May 2026, after first online publication: The word 'treatment-naïve' has been corrected to 'post-neoadjuvant chemotherapy' in the preceding sentence.] Conversely, similar changes seen in node-positive BC significantly worsened survival (p = 0.0407), regardless of BC subtype or treatment. In metastatic ALNs, FRC network disruption grew proportionately to axillary tumour burden, and this significantly correlated with poorer outcomes (p = 0.043). Interestingly, increased FRC alignment within these metastases significantly improved survival (p = 0.0205). This study showed that changes in human ALN FRC network topology predicts BC prognosis. This could improve how we risk stratify patients in future, and provide a new avenue for mechanistic, translational research. © 2026 The Author(s).
