Mesothelin (MSLN) is Highly Expressed in Triple Negative Breast Cancer and is Associated with Enhanced Cell Proliferation and Proinflammatory Tumor Microenvironment.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundMesothelin (MSLN), a cell surface glycoprotein, is commonly expressed in several cancers, including 40% of triple negative breast cancer (TNBC) cases. Although its cellular or physiologic functions remain unclear, MSLN has been leveraged as a target for molecular therapies. This study investigates MSLN's potential role in TNBC, the breast cancer (BC) subtype with poorest outcomes. PATIENTS AND
methodsThe breast cancer (BC) cohorts from the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC, n = 313), The Cancer Genome Atlas (TCGA, n = 160), and SCAN-B (n = 155) were used to obtain biological variables and gene expression data.
resultsHigh MSLN expression was primarily observed in epithelial cells, and its expression was associated with reduced stromal adipocytes in the tumor microenvironment (TME), supporting its role as a TNBC surface marker. MSLN expression was also associated with the TNBC subtype and advanced N stages in BC. However, MSLN expression did not correlate with long-term survival outcomes, including overall survival (OS), disease-specific survival (DSS), or disease-free survival (DFS); nevertheless, it was still associated with favorable response to neoadjuvant chemotherapy (NAC). Indeed, MSLN-high tumors exhibited a proinflammatory microenvironment, higher cancer-testis antigen (CTA) scores, and increased immune cell activity, notably immature dendritic cells (iDCs) and M1 macrophages. Biologically, MSLN expression was linked to increased cellular proliferation, with gene set enrichment analysis (GSEA) showing enrichment in pathways related to rapid proliferation, such as G2M checkpoint and E2F targets.
conclusionsMSLN-high TNBC is characterized by increased tumor grade, enhanced cell proliferation, and a proinflammatory microenvironment, showing better response to neoadjuvant chemotherapy without significant impact on long-term survival outcomes.
