【摘要】：目的:探討胸腺上皮性腫瘤(TET)簡化病理分型的CT表現(xiàn)特征及術(shù)前CT預(yù)測TET簡化病理分型的價值。方法:回顧性分析經(jīng)病理證實的68例TET的CT表現(xiàn),按照WHO組織學(xué)分型后簡化分為三組:低危組(A、AB、B1),高危組(B2、B3)和胸腺癌組;各組間比較采用卡方檢驗及單因素方差分析。結(jié)果:低危組11例,高危組42例,胸腺癌組15例。胸腺癌腫塊更大,呈灌注式生長,更加邊界不清、密度不均,并更多侵犯周圍組織、縱隔淋巴結(jié)腫大或轉(zhuǎn)移及胸膜轉(zhuǎn)移(P0.05)。重癥肌無力更多見于胸腺瘤(P0.05)�？缰芯�生長、邊緣不規(guī)則或分葉狀提示胸腺癌或高危胸腺瘤(P0.05),胸痛癥狀更常見于胸腺癌組(P0.05)。鈣化、平掃CT值、胸腔積液在各組間未見統(tǒng)計學(xué)差異。結(jié)論:TET簡化病理分型間的CT表現(xiàn)具有一定差異性,良好的術(shù)前CT增強檢查可較好預(yù)測其分型,幫助臨床制訂治療方案。
[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.
