1 · What the graph read from 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.

2 · The registry

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

Tumor microenvironment-resident immunosuppressive cells-comprising myeloid-derived suppressor cells, regulatory T cells, and tumor-associated macrophages-constitute primary obstacles to effective cancer immunotherapy. Advances in single-cell and spatial multi-omics have uncovered their substantial functional heterogeneity, tissue-adaptive reprogramming, and organ-specific architectures distinguishing primary tumors from metastatic lesions. Beyond canonical immune checkpoint pathways, non-canonical regulatory layers--including metabolic-immune crosstalk, epigenetic regulation, microbiome-mediated distant signaling, and therapy-induced adaptive remodeling-further reinforce treatment resistance. Based on these mechanistic insights, systematic synergistic strategies have been developed, such as multi-pathway checkpoint blockade, ADC-immunotherapy combinations, temporally and spatially optimized conventional therapies, and targeted agents that deplete or reprogram suppressive populations. Emerging biomarkers, repurposed pharmaceuticals, and pan-cancer therapeutic principles are refining patient stratification and combination regimens. This review offers a comprehensive framework for understanding and surmounting immunosuppressive barriers in cancer therapy.
