Prognostic and histologic significances of the expression profile of membrane tissue factor for aggressive endometrial carcinomas.
Article in The oncologist, 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
backgroundTissue factor (TF) is involved in tumor-induced coagulation cascade, which plays crucial roles in the tumor microenvironment, and is being clinically explored as a therapeutic target. However, the prognostic role of TF and the related proteins in endometrial cancer is yet to be clarified and was systematically investigated in this study. MATERIALS AND
methodsThe expression profiles of membrane/cytoplasmic TF, nuclear/cytoplasmic phospho-TF (p-TF), PAR-1, PAR-2, VEGF as well as CD8, a marker for cytotoxic T cells, in tumors from 229 patients with endometrial carcinoma were immunohistochemically evaluated and correlated with clinicopathologic parameters and patient survival. Bioinformatics analyses were further conducted to strengthen the observations.
resultsHigh membrane TF (mTF) expression correlated with worse overall survival (OS), and was found to be an independent prognostic factor for unfavorable OS by the univariate and multivariate analyses (P = .028 and .0087). High mTF expression correlated with aggressive histology, and remained independent for unfavorable OS even in the aggressive histological subset (P = .037 and .0064). Moreover, mTF expression inversely correlated with CD8+ tumor-infiltrating immune cell count, and TF expression positively correlated with the infiltration of Treg cells, known to suppress CD8+ T cells, by the The Cancer Genome Atlas (TCGA) data analysis (P = .037 and .0015), suggesting that the detrimental prognostic role of mTF involves immune evasion.
conclusionsTaken together, mTF serves as a potential biomarker for patient prognosis and therapeutic target for the aggressive histological type of tumor, providing significant rationales for incorporating TF-directed drugs into the novel strategy for refractory endometrial carcinomas.
