CD155 as a prognostic and predictive biomarker in acute myeloid leukemia.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAcute myeloid leukemia (AML) is a heterogeneous hematological malignancy with different molecular and genetic alterations. CD155 is expressed on myeloid cells and serves as a recognition molecule for natural killer (NK) cells to induce cytotoxicity. This study aimed to assess the prognostic and predictive value of CD155 in patients with AML.
methodsWe studied the expression of CD155 via flow cytometry in 93 AML patients at initial diagnosis at the Medical Oncology Department, South Egypt Cancer Institute (SECI), Egypt.
resultsFlow cytometry revealed that a mean fluorescence intensity ratio (MFIR) ≥2.68 was associated with high CD155 expression. This criterion was met in 62 patients (66.7%). High expression was associated with a worse composite complete remission (CRc) rate than low expression (29.0 vs. 54.8%; P = 0.015). High CD155 expression had significantly shorter relapse-free survival (RFS), with a median of 1.68 (95% CI 0.92-2.43) months (P = 0.015), and overall survival (OS), with a median of 1.68 (95% CI 0.74-2.88) months (P = 0.041).
conclusionsHigh expression of CD155 in adult patients with AML is associated with a lower CRc, shorter RFS, and OS. It could be included within the predictive and prognostic panels.
