Antitumor CD4+ T Helper 1 Cells Target and Control the Outgrowth of Disseminated Cancer Cells.
Article in Cancer immunology research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Detection of disseminated cancer cells (DCC) in the bone marrow (BM) of patients with breast cancer is a critical predictor of late recurrence and distant metastasis. Conventional therapies often fail to completely eradicate DCCs in patients. In this study, we demonstrate that intratumoral priming of antitumor CD4+ T helper 1 (Th1) cells was able to eliminate the DCC burden in distant organs and prevent overt metastasis, independent of CD8+ T cells. Intratumoral priming of tumor antigen-specific CD4+ Th1 cells enhanced their migration to the BM and distant metastatic site to selectively target DCC burden. The majority of these intratumorally activated CD4+ T cells were CD4+PD1- T cells, supporting their nonexhaustion stage. Phenotypic characterization revealed enhanced infiltration of memory CD4+ T cells and effector CD4+ T cells in the primary tumor, tumor-draining lymph node, and DCC-driven metastasis site. A robust migration of CD4+CCR7+CXCR3+ Th1 cells and CD4+CCR7-CXCR3+ Th1 cells into distant organs further revealed their potential role in eradicating DCC-driven metastasis. The intratumoral priming of antitumor CD4+ Th1 cells failed to eradicate DCC-driven metastasis in CD4- or IFN-γ knockout mice. Moreover, antitumor CD4+ Th1 cells, by increasing IFN-γ production, inhibited various molecular aspects and increased classical and nonclassical MHC molecule expression in DCCs. This reduced stemness and self-renewal while increasing immune recognition in DCCs of patients with breast cancer. These results unveil an immune basis for antitumor CD4+ Th1 cells that modulate DCC tumorigenesis to prevent recurrence and metastasis in patients.
