Staging classification is essential in cancer management and is based on three components: tumor extent (T), lymph node involvement (N), and distant metastatic disease (M). For thymic epithelial malignancies, clinical Tumour, Node, Metastasis (cTNM) staging is primarily determined by imaging, making radiologists integral to clinical practice, treatment decisions, and maintaining the quality of staging databases. The ninth edition of the TNM classification for thymic epithelial tumors will be implemented in January 2025. This review outlines the definitions for the TNM categories in the updated edition, provides examples, and elaborates on the radiologist's role and imaging considerations.
分期分类在癌症管理中至关重要，它基于三个要素：肿瘤范围（T）、淋巴结受累情况（N）和远处转移疾病（M）。对于胸腺上皮性恶性肿瘤，临床肿瘤、淋巴结、转移（cTNM）分期主要通过影像学确定，这使得放射科医生成为临床实践、治疗决策以及维持分期数据库质量不可或缺的一部分。胸腺上皮肿瘤TNM分类的第九版将于2025年1月实施。本综述概述了更新版中TNM类别的定义，提供了示例，并阐述了放射科医生的作用及影像学考量。
