Anatomical location defines distinct molecular subtypes of mucosal melanoma.
Article in ESMO open, 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
backgroundMucosal melanoma (MM) is a rare and aggressive melanoma subtype that is understudied. The relationships between anatomical location, genomic alterations, stage at presentation, and survival remain incompletely characterized.
methodsWe carried out a retrospective single tertiary center study of 105 patients with histologically confirmed MM diagnosed between 1996 and 2025. Clinical and genomic data were analyzed to evaluate associations between anatomical location, mutational profile, stage at presentation, and survival outcomes, including melanoma-specific mortality.
resultsLower-body tumors arising in the anus or genital areas were enriched for KIT and splicing factor 3 subunit B1 alterations, whereas NRAS mutations were distributed across anatomical regions. Among the two most common mutated genes, NRAS-mutant tumors were more likely than KIT-mutant tumors to present with metastatic disease [53% versus 19%; P = 0.046, odds ratio (OR) 4.7, 95% confidence interval (CI) 1.15-19.41]. Lower-body tumors were associated with worse overall survival (OS) than upper-body tumors (median 2.81 versus 8.40 years; OR = 0.05) and with higher melanoma-specific mortality. In multivariable analyses, upper-body location remained independently associated with improved OS (hazard ratio 0.14, 95% CI 0.05-0.36, P < 0.001).
conclusionsAnatomical location of MMs and genomic alterations define biologically and clinically distinct subtypes.
