Is Aneuploidy a Consistent Marker for Malignant Transformation Risk in Oral Lichen Planus?
Article in Head and neck pathology, 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
backgroundNumeric chromosomal imbalance, known as aneuploidy, is linked to both malignant and potentially malignant epithelial lesions. Aneuploidy has also been investigated in oral potentially malignant disorders (OPMDs) due to its high incidence in head and neck cancers, particularly in oral squamous cell carcinoma (OSCC). The study aimed to evaluate the potential of aneuploidy, a marker of chromosomal imbalance, as a prognostic tool for assessing malignant transformation risk in oral lichen planus (OLP) patients.
methodsFluorescent in situ hybridization (FISH) analysis targeting centromeric probes for chromosomes 2 and 8 was conducted on samples from 245 patients, with follow-up in 135 cases.
resultsAneuploid cells (ACs) were detected in 73 patients (29.8%); 24 (32.9%) exhibited non-diploid cells in a normal looking mucosa. Only 2 (0.8%) patients developed OSCC during the follow-up. Among the 135 followed, 11 (8.1%) were positive for Acs in both samples, 15 (11.1%) were were negative initially but positive later. In contrast, 3 patients (2.2%) were initially positive but later negative.
conclusionThese results indicate a low malignant transformation rate (< 1%), despite a high rate of aneuploidy. These also demonstrate variability in aneuploidy results over time. The dynamic nature of aneuploidy observed suggests that it may not be a reliable predictive tool for malignant transformation in OLP.
