Molecular profiling of rare thymoma using next-generation sequencing: meta-analysis

Molecular profiling of rare thymoma using next-generation sequencing: meta-analysis AbstractBackgroundThymomas belong to rare tumors giving rise to thymic epithelial tissue. There is a classification of several forms of thymoma: A, AB, B1, B2, B3, thymic carcinoma (TC) and thymic neuroendocrine thymoma. In this meta-analysis study, we have focused on thymoma using articles based on the disease’s next-generation sequencing (NGS) genomic profiling.Materials and methodsWe conducted a systematic review and meta-analysis of the prevalence of studies that discovered the genes and variants occurring in the less aggressive forms of the thymic epithelial tumors. Studies published before 12th December 2022 were identified through PubMed, Web of Science (WoS), and SCOPUS databases. Two reviewers have searched for the bases and selected the articles for the final analysis, based on well-defined exclusion and inclusion criteria.ResultsFinally, 12 publications were included in the qualitative as well as quantitative analysis.

Abstract

AbstractBackgroundThymomas belong to rare tumors giving rise to thymic epithelial tissue. There is a classification of several forms of thymoma: A, AB, B1, B2, B3, thymic carcinoma (TC) and thymic neuroendocrine thymoma. In this meta-analysis study, we have focused on thymoma using articles based on the disease’s next-generation sequencing (NGS) genomic profiling.Materials and methodsWe conducted a systematic review and meta-analysis of the prevalence of studies that discovered the genes and variants occurring in the less aggressive forms of the thymic epithelial tumors. Studies published before 12th December 2022 were identified through PubMed, Web of Science (WoS), and SCOPUS databases. Two reviewers have searched for the bases and selected the articles for the final analysis, based on well-defined exclusion and inclusion criteria.ResultsFinally, 12 publications were included in the qualitative as well as quantitative analysis. The three genes, GTF2I, TP53, and HRAS, emerged as disease-significant in the observed studies. The Odds Ratio for all three extracted genes GTF2I (OR = 1.58, CI [1.51, 1.66] p < 0.00001), TP53 (OR = 1.36, CI [1.12, 1.65], p < 0.002), and HRAS (OR = 1.02, CI [1.00, 1.04], p < 0.001).ConclusionsAccording to obtained data, we noticed that the GTF2I gene exhibits a significant prevalence in the cohort of observed thymoma patients. Moreover, analyzing published articles NGS has suggested GTF2I, TP53, and HRAS genes as the most frequently mutated genes in thymoma that have pathogenic single nucleotide variants (SNV) and Insertion/Deletion (InDel), which contribute to disease development and progression. These variants could be valuable biomarkers and target points specific to thymoma.
