英文摘要：

Thymomas (THs) are a unique group of heterogeneous tumors of the thymic epithelium. In particular, the subtypes B2 and B3 tend to be aggressive and metastatic. Radical tumor resection remains the only curative option for localized tumors, while more advanced THs require multimodal treatment. Deep sequencing analyses have failed to identify known oncogenic driver mutations in TH, with the notable exception of theGTF2Imutation, which occurs predominantly in type A and AB THs. However, there are multiple alternative non-mutational mechanisms (e.g., perturbed thymic developmental programs, metabolism, non-coding RNA networks) that control cellular behavior and tumorigenesis through the deregulation of critical molecular pathways. Here, we attempted to show how the results of studies investigating such alternative mechanisms could be integrated into a current model of TH biology. This model could be used to focus ongoing research and therapeutic strategies.

胸腺瘤是一组独特的异质性胸腺上皮肿瘤。其中，B2和B3亚型往往具有侵袭性和转移倾向。对于局限性肿瘤，根治性手术切除仍是唯一治愈手段，而更晚期的胸腺瘤则需要多模式综合治疗。深度测序分析未能发现胸腺瘤中存在已知的致癌驱动基因突变，但值得注意的是，GTF2I突变主要出现在A型和AB型胸腺瘤中。然而，存在多种非突变性替代机制（如胸腺发育程序紊乱、代谢异常、非编码RNA网络失调等），通过干扰关键分子通路来调控细胞行为与肿瘤发生。本文旨在探讨如何将这些替代机制的研究成果整合到当前胸腺瘤生物学模型中，该模型可为持续的研究和治疗策略提供方向性指导。
