目的:分析多层螺旋CT(MSCT)表现评估胸腺上皮肿瘤(TET)术后预后的应用价值。方法:回顾性分析手术及病理证实的64例TET患者MSCT表现和随访资料。记录瘤体大小、形状、边缘、密度、强化程度、有无纵隔淋巴结肿大、有无附近组织侵犯以及远处转移。根据患者存活时间,将患者分为存活时间>5年组和存活时间<5年组,比较两组患者相关参数差异。结果:与存活时间<5年组相比,存活时间>5年组患者年龄和瘤体大小较小,肿瘤边缘光滑和密度均匀比率较高,淋巴结肿大、周围组织侵犯和转移比率较低,差异有统计学意义(P<0.05)。患者性别、肿瘤形状及肿瘤强化程度两组之间差异无统计学意义(P>0.05)。结论:MSCT表现对TET患者预后评价具有重要作用,是术前评估患者预后较理想的选择。
Objective: To evaluate the value of multi-slice spiral computed tomography (MSCT) in evaluating postoperative prognosis of thymus tumor (TET). Methods: MSCT findings and follow-up data of 64 TET patients confirmed by surgery and pathology were retrospectively analyzed. Record tumor size, shape, edge, density, degree of enhancement, with or without mediastinal lymph nodes, with or without nearby tissue invasion and distant metastasis. According to the survival time of patients, the patients were divided into 5-year survival group and 5-year survival group, and the differences between the two groups were compared. Results: Compared with survival time less than 5 years, patients with survival time> 5 years had a smaller age and tumor size, a smoother edge and a higher density, lymphadenopathy, a lower rate of surrounding tissue invasion and metastasis, The difference was statistically significant (P <0.05). There was no significant difference between the two groups in gender, tumor shape and tumor enhancement (P> 0.05). Conclusion: The performance of MSCT plays an important role in the prognosis evaluation of patients with TET. It is an ideal choice to evaluate the prognosis of patients with TET.
