1 · What the graph read from it

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.

2 · The registry

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

The high-and in most countries steadily increasing-incidence of cutaneous squamous cell carcinoma (cSCC) represents a growing public health challenge. As the majority of cSCCs arise from pre-existing actinic keratosis (AKs), these lesions are recognized as the principal precursors of invasive disease. A comprehensive understanding of the molecular mechanisms driving the progression from AK to cSCC is essential for advancing prevention, facilitating early diagnosis, and enabling targeted therapies. Moreover, this knowledge provides a basis for identifying biomarkers that can predict the risk of malignant transformation. The progression from AK to cSCC is a complex, multistep process driven by the gradual accumulation of genetic, epigenetic, and microenvironmental alterations. Over the past decades, numerous molecular changes associated with this transition have been identified. However, no single biomarker has demonstrated sufficient predictive accuracy for clinical use. This reflects the pronounced molecular heterogeneity of AKs as no individual alteration is uniformly present in all lesions that undergo malignant progression. In addition, numerous proposed biomarkers are also detected in non-progressive AKs and even in non-neoplastic skin, which compromises their sensitivity and specificity for predicting progression to cSCC. Current evidence, therefore, suggests that the most promising strategy for identifying AKs at greatest risk of malignant transformation is the development of a multi-marker panel. This panel, ideally, should integrate molecular signatures encompassing genetic, epigenetic, proliferative, inflammatory, and microenvironmental markers. This review summarizes the molecular factors that currently represent the most promising candidates for inclusion in such a multi-marker panel and discusses their potential clinical utility, while emphasizing the need for validation in well-designed prospective longitudinal studies.
