Research trends of tumor-associated macrophages in colorectal cancer: a bibliometric analysis.
Article in International journal of surgery (London, England), 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
backgroundColorectal cancer (CRC) represents the third most prevalent malignancy worldwide and accounts for the second-highest cancer-related mortality rate. Accumulating evidence over the past decade has established the pivotal role of tumor-associated macrophages (TAMs) in CRC tumorigenesis and disease progression. This study employs bibliometric analysis to delineate the research landscape and emerging frontiers in CRC TAMs investigation.
methodsWe systematically retrieved publications indexed in the Web of Science Core Collection from database inception through 14 April 2025, applying predefined inclusion and exclusion criteria. Using VOSviewer and CiteSpace, we conducted comprehensive visual analyses of the CRC TAMs research domain, including country contributions, institutional productivity, annual publication trends, and journal distributions.
resultsOur bibliometric analysis identified 2861 publications on CRC TAMs worldwide, with a consistent upward publication trend since 2018. Geospatial analysis revealed that China and the United States are the predominant contributing nations, with Sun Yat-sen University being the most productive institution. Keyword co-occurrence mapping identified five predominant research clusters: CRC biology, TAMs characterization, patient survival outcomes, disease progression mechanisms, and metastatic processes. Four key research directions emerged: (1) single-cell RNA sequencing for TAMs heterogeneity analysis, (2) PD-1/PD-L1 checkpoint interactions with TAMs, (3) molecular mechanisms underlying macrophage polarization, and (4) chemotherapeutic modulation of TAMs functionality (particularly irinotecan). These advances provide mechanistic insights into CRC TAMs biology and may facilitate (1) the discovery of novel diagnostic biomarkers, (2) precision therapeutic strategies, and (3) personalized prognostic frameworks.
conclusionBibliometric analysis has highlighted the global landscape of research on CRC TAMs. Future research directions in CRC TAMs are likely to center on the integration of multi-omics, in-depth investigation of the tumor microenvironment, targeting TAMs, application of machine learning and artificial intelligence, and the development of personalized treatment strategies for CRC.
