The molecular mechanisms of platelets in tumor invasion and metastasis: a controversial role.
Review in Cancer biology & therapy, 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
Platelets, traditionally recognized for their role in hemostasis, are now understood to actively contribute to tumor progression, angiogenesis, and metastasis. Through dynamic bidirectional interactions with cancer cells, platelets undergo measurable alterations in count, mean platelet volume, and molecular cargo, including proteins and mRNAs, supporting their potential utility as liquid biopsy biomarkers for early cancer detection. Within the tumor microenvironment, platelets contribute to immune evasion, support tumor cell intravasation and extravasation, enhance the survival of circulating tumor cells, and promote neovascularization. In addition, they can physically shield malignant cells from immune surveillance, thereby increasing metastatic potential. Although context-specific anti-tumor effects have been reported, the predominant evidence supports a largely pro-tumorigenic and pro-metastatic role for platelets. Elucidating the molecular mechanisms underlying platelet-tumor interactions is therefore essential for improving cancer risk stratification, prognostic evaluation, and therapeutic development. This review summarizes current advances in platelet-derived biomarkers and discusses emerging therapeutic strategies targeting platelet-mediated pathways to suppress metastasis and improve clinical outcomes in cancer patients.
