Mutations of the DICER1 gene among children and adolescents with thyroid cancer: a systematic review.
Synthesis in Pediatric research, 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
backgoundThe DICER1 gene located on chromosome 14q, essential for the maturation of miRNAs, is commonly associated with multinodular goiter and thyroid carcinomas. We aimed to systematically search the literature and identify mutations in the DICER1 gene associated with thyroid cancer in children and adolescents.
methodsThe study was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement through four databases (Pubmed, Web of Science/Scopus/Google Scholar). The quality of the studies was assessed using the ROBINS-1 tool.
resultsA total of 1672 articles were retrieved through databases. After applying the inclusion/exclusion criteria, 32 original studies were systematically reviewed. Genomic mutations in the DICER1 gene lead to DICER1 syndrome, which is more commonly associated with multinodular goiter than with thyroid carcinomas. The most common type of thyroid cancer in the setting of DICER1 gene mutations is papillary thyroid carcinoma, followed by follicular thyroid carcinoma and poorly differentiated thyroid cancer. Additionally, other rare histological types may occur. These mutations have been associated with capsular invasion and do not often metastasize to lymph nodes or distant organs.
conclusionMutations in the DICER1 gene appear to be more commonly associated with thyroid cancer in children than in adults, particularly with differentiated thyroid carcinoma. IMPACT: The impact of this study is to provide a systematic analysis of DICER1 mutations in pediatric and adolescent thyroid cancer, summarizing its prevalence, clinical significance and molecular mechanisms in this specific population group. By integrating current evidence, this study highlights the role of DICER1 gene in tumorigenesis and supports future research and clinical decision-making in thyroid cancer among children and adolescents.
