作者分析了127例胸腺瘤切除病人的临床病理特点,合并症和治疗方法与肿瘤复发的相关因素。127例胸腺瘤病人中,75例伴有重症肌无力,52例没有重症肌无力。侵入性胸腺瘤临床分期标准为Ⅰ期:肉眼可见到胸腺瘤的包膜完整,镜下被膜未受侵犯;Ⅱ期:肉眼见胸腺瘤侵犯周围脂肪组织或纵隔胸膜,镜下见侵入被膜;Ⅲ期:肉眼见胸腺瘤侵入邻近结构(心包、大血管或肺);Ⅳ期 a:胸腺瘤扩散到胸膜或心包;Ⅳ期 b:胸腺瘤转移到淋巴结和经循环散布。胸腺瘤组织学分类按肿瘤的淋巴细胞和上皮细胞的比率分为淋巴型、淋巴上皮型和上皮型,依每个病灶上皮细胞
The author analyzed the clinicopathological features of 127 patients with thymectomy and related factors of comorbidities and treatment methods and tumor recurrence. Of the 127 patients with thymoma, 75 had MG and 52 had no myasthenia gravis. The clinical staging of invasive thymoma is stage I: the thymoma capsule is visible to the naked eye and the capsule is not invaded; phase II: the thymoma invades surrounding adipose tissue or the mediastinal pleura under the naked eye, and the invading capsule is seen under the microscope; III Period: thymoma invades adjacent structures (pericardium, large blood vessels, or lungs); Stage IVa: Thymomas spread to the pleura or pericardium; Stage IVb: Thymomas metastasize to lymph nodes and are disseminated by circulation. The histological classification of thymoma is divided into lymphoid type, lymphoepithelial type, and epithelial type according to the ratio of lymphocytes and epithelial cells of the tumor, according to the epithelial cells of each lesion.
