Immunohistochemical insights into the pathogenesis of colonic sessile serrated lesions.
Article in Archive of clinical cases, 2025. 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
backgroundSessile serrated lesions (SSLs) are recognized as precursor lesions in the pathogenesis of colorectal cancer, particularly in the context of microsatellite instability (MSI). This study evaluates the role of immunohistochemical (IHC) markers in understanding the molecular and immunologic characteristics of SSLs. MATERIALS AND
methodsA retrospective analysis was performed on 45 colonic neoplastic lesions diagnosed as SSLs. An IHC staining panel was conducted, including MLH1, p53, CD44, CD3, CD8, MUC2, MUC5AC, MUC6, chromogranin and Ki67 antibodies.
resultsMLH1 and p53 expressions showed correlations with dysplastic changes. Immunological markers CD3 and CD8 indicated a variable immune response, potentially reflecting the tumor's ability to evade immune surveillance in certain situations. CD44 was overexpressed in all SSLs. The number of neuroendocrine cells was overall reduced.
conclusionsSSLs are heterogeneous lesions, exhibiting a wide range of histological and molecular features. Using IHC might enhance diagnostic accuracy, particularly in lesions with ambiguous histological features, when dysplasia develops. Accurate identification of SSLs and understanding their molecular characteristics are crucial for assessing their malignant potential.
