Immune Activation Signatures Associated with Fatigue in Cancer Patients Undergoing Immune Checkpoint Inhibitor Therapy.
Article in Cancer research communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
Fatigue is a common and often debilitating adverse event among patients receiving immune checkpoint inhibitor (ICI) therapy, yet its underlying immunologic mechanisms remain poorly defined. We prospectively collected clinical data and blood samples from patients with solid tumors receiving ICI therapy. Patients were prospectively surveyed at month 2, 4, or 6 on treatment to assess for the presence and severity of fatigue as compared with treatment baseline. We analyzed peripheral lymphocyte populations by cytometry by time of flight and peripheral levels of 39 cytokines with a Luminex multiplex assay to identify dynamic immune changes associated with ICI-related fatigue. Of 53 patients enrolled, 31 (58.5%) reported worsening fatigue during ICI therapy. Patients reporting fatigue exhibited broad early-treatment elevations in circulating cytokines, with the most prominent increases observed in the Th1-associated cytokine cluster, including IFN-γ, IL-2, and IL-12. In parallel, several clusters of cytotoxic effector CD8+ T cells expanded significantly from baseline in the fatigued group. Fatigue was not associated with objective tumor response or with the development of other clinically meaningful immune-related adverse events. In a pan-tumor cohort treated with ICIs, increases in clusters of cytotoxic effector CD8+ T cells in parallel with related Th1-associated cytokines were associated with ICI-related fatigue, implicating fatigue as a potential marker of immune activation in this population. SIGNIFICANCE: This study illuminates dynamic changes in peripheral cytokines and immune cell clusters that are associated with ICI-related fatigue. Namely, this study implicates the Th1 pathway as a novel contributor to ICI-related fatigue and identifies ICI-related fatigue as a clinical surrogate for immune activation in patients receiving ICI therapy. Recognizing that fatigue may be a biomarker of heightened immune activity influences monitoring strategies and informs supportive care interventions during immunotherapy.
