Clonal tracing of rare anal metastasis in esophageal squamous cell carcinoma: a case report with whole-exome sequencing and multimodal therapy.
Article in Frontiers in immunology, 2026. 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
Esophageal squamous cell carcinoma (ESCC) shows considerable variation in incidence across different regions and is affected by various risk factors, including smoking and HPV infection. This article presents a rare case of ESCC that metastasized to the anal region, illustrating the effectiveness of whole-exome sequencing and clonal evolution analysis in identifying the origins of the metastasis. The findings reveal distinct clonal characteristics between the primary tumor and the metastatic site. This underscores the importance of molecular profiling for developing effective treatment strategies.
