The hotspots and publication trends in photodynamic therapy/photothermal therapy for gastric cancer: a bibliometric analysis.
Article in Discover oncology, 2025. 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
backgroundGastric cancers (GC) place a heavy burden on patients, families, and society. Photodynamic therapy (PDT)/photothermal therapy (PTT) for GC has emerged as an important area of research. This study aimed to conduct a bibliometric analysis to examine the development trends, research hotspots, and future directions in this field.
methodsPublications from 1987 to 2024 were retrieved from the Web of Science Core Collection database. Bibliometric data were analyzed using the R package "Bibliometrix", VOSviewer, and CiteSpace.
resultsA total of 381 articles related to PDT/PTT for GC were covered in this study. Gastrointestinal Endoscopy was the most influential journal in its field with h-index of 11. China had the highest publication volume (138). Cui Daxiang was the key author with the most publications (12) and an h-index of 10. The Southern Medical University was the institution with the most publications (29). Keyword co-occurrence analysis showed five categories, including nanomaterials, mechanisms, combined therapy, technology, and photosensitizers. Keywords burst analysis showed emerging interests in "nanoparticles" and "release".
conclusionsThis bibliometric analysis provides a comprehensive overview of research on PDT/PTT for GC from 1987 to 2024, identifying key contributors, research hotspots, and emerging trends. Research hotspots reflected efforts to optimize diagnosis and therapies via photosensitizers for GC and to combine PDT/PTT with other therapies for GC. Future research should focus on the deep integration of nanomaterials as delivery system with PDT/PTT for GC and more sensitive PDT/PTT techniques for guiding surgery.
