Mast Cells Accumulate in the Stroma of Breast Adenocarcinoma and Secrete Pro-Inflammatory Cytokines and Tumor-Damaging Mediators: Could IL-37 and IL-38 Play an Anti-Tumor Role?
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Tumor tissue is surrounded by mast cells (MCs), which participate in the inflammatory immune response by producing cytokines, proteases, and other molecules. MCs are involved in both innate and acquired immunity and are associated with the IgE response through the FcεRI receptor. MCs mediate inflammation in several immune reactions, including acute hyperreactivity, leukocyte recruitment, acute tissue swelling, anaphylaxis, and pro-inflammatory cytokine production. They not only function as pro-inflammatory effector cells but may also contribute to the regulation of the acquired immune response in tumor tissue. Therefore, MCs may mediate immunity in breast cancer by promoting remodelling and counteracting cancer growth. They also produce anti-inflammatory substances, such as histamine, transforming growth factor-β (TGF-β)1, IL-10, and IL-4, which inhibit the acquired immune response and reduce the inflammatory state. IL-37 and IL-38 are novel natural regulators of inflammation and are anti-inflammatory members of the IL-1 family. IL-1, generated by immune cells such as macrophages and lymphocytes, is released downstream of oncogenes in breast cancer, triggering an inflammatory response by stimulating other pro-inflammatory cytokines such as IL-6, tumor necrosis factor (TNF), and IL-33 (an early warning cytokine). Therefore, blocking IL-1 with IL-37 or IL-38 could represent a novel therapeutic strategy that, when combined with other treatments, could be beneficial in breast cancer. This review focuses on the new discoveries and insights into the role of MCs in breast cancer. We also analyzed molecules that can promote tumor growth and those that can inhibit cancer development and metastasis. This review aims to study the role of MCs accumulated in the stroma of breast adenocarcinoma in relation to secreted anti-inflammatory cytokines, such as IL-37 and IL-38.
