【摘要】：目的:探讨胸腺上皮性肿瘤(TET)简化病理分型的CT表现特征及术前CT预测TET简化病理分型的价值。方法:回顾性分析经病理证实的68例TET的CT表现,按照WHO组织学分型后简化分为三组:低危组(A、AB、B1),高危组(B2、B3)和胸腺癌组;各组间比较采用卡方检验及单因素方差分析。结果:低危组11例,高危组42例,胸腺癌组15例。胸腺癌肿块更大,呈灌注式生长,更加边界不清、密度不均,并更多侵犯周围组织、纵隔淋巴结肿大或转移及胸膜转移(P0.05)。重症肌无力更多见于胸腺瘤(P0.05)。跨中线生长、边缘不规则或分叶状提示胸腺癌或高危胸腺瘤(P0.05),胸痛症状更常见于胸腺癌组(P0.05)。钙化、平扫CT值、胸腔积液在各组间未见统计学差异。结论:TET简化病理分型间的CT表现具有一定差异性,良好的术前CT增强检查可较好预测其分型,帮助临床制订治疗方案。
[Abstract]:Objective: to investigate the CT features of simplified pathological classification of thymic epithelial tumor (Tet) and the value of preoperative CT in predicting simplified pathological classification by TET. Methods: Ct findings of 68 cases of TET confirmed by pathology were retrospectively analyzed and divided into three groups according to the histological classification of WHO: low risk group, high risk group, high risk group and thymic carcinoma group, chi-square test and univariate analysis of variance were used. Results: low risk group (n = 11), high risk group (n = 42) and thymic carcinoma group (n = 15). The tumor of thymic carcinoma is larger, more perfusion growth, more unclear boundary, uneven density, and more invasion of surrounding tissue, mediastinal lymph node enlargement or metastasis, and pleural metastasis P0.05. Myasthenia gravis was more common in thymoma (P 0.05). Growth across the midline, irregular or lobular margin suggested that thymic carcinoma or high risk thymoma P0.05, chest pain symptoms are more common in the thymic carcinoma group P0.05. There was no significant difference in calcification, CT value and pleural effusion. Conclusion the CT findings among the simplified pathological types of Tet have some differences. Good CT enhanced examination before operation can predict the classification of CT and help to make the treatment plan.
