Separability of histopathology foundation model embeddings of stimulated Raman histology images for lung carcinoma subtyping.
Article in Journal of Cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Histopathology foundation models trained on hematoxylin and eosin (H&E) whole-slide images have recently emerged as versatile encoders for downstream diagnostic tasks, but their transferability to out-of-domain imaging modalities such as stimulated Raman histology (SRH) is unknown. Here, we retrospectively evaluated whether embeddings from histopathology foundation models enable intraoperative SRH-based classification of lung cancer patients into (i) non-small cell lung cancer (NSCLC) versus pulmonary metastasis (MET) and (ii) adenocarcinoma (AC) versus squamous cell carcinoma (SCC). For NSCLC versus MET, embeddings from histopathology foundation models showed separability in a range comparable to ResNet50. In contrast, for AC versus SCC, histopathology foundation models showed a tendency to outperform ResNet50, although without statistical significance. Overall performance remained too low to support clinical deployment. Nonetheless, our results indicate that histopathology foundation models could transfer discriminative representations to SRH images for specific intraoperative subtyping tasks.
