【摘要】：目的分析肾透明细胞癌和非透明细胞恶性肿瘤CT表现特点的差异,探讨其在鉴别诊断中的价P$。材料与方法对61例患者共39例透明细胞癌和22例非透明细胞恶性肿瘤进行回顾性分析,评估指标包括:患者的年龄和性别、肿瘤大小、边缘和位置、是否存在出血、坏死或钙化、病变的增强程度、增强及有无转移等,探讨两类肾脏恶性肿瘤之间的差异。结果非透明细胞恶性肿瘤组(6/22)的钙化要多于透明细胞癌(3/39)(P=0.038);透明细胞癌多累及肾脏的一极,而多数非透明细胞恶性肿瘤累及2个以上的肾极,并具有统计学差异(P0.05)。19个非透明细胞恶性肿瘤强化不均,明显多于透明细胞癌(21/39)(P0.05)。另外,在肾皮质和髓质期,两组肿瘤的强化程度均具有显著性差异(P0.05)。乏血管透明细胞癌和非透明细胞恶性肿瘤的病变直径分别为3.9±1.9 cm和6.2±2.9cm,具有统计学差异(P = 0.023),非透明细胞恶性肿瘤内坏死数量多于乏血供透明细胞癌(P = 0.004)。19个非透明细胞恶性肿瘤为不均匀强化,而仅有2个乏血供透明细胞癌为不均匀强化(P = 0.003)。其余评价参数在两组之间未见统计学差异(P0.05)。结论肾脏透明细胞癌和非透明细胞恶性肿瘤的CT特点具有一定的差异,可为两者的鉴别诊断提供一定的信息。
[Abstract]:Objective to analyze the difference of CT features between renal clear cell carcinoma and non-transparent cell carcinoma. Materials and methods A retrospective analysis was performed on 39 cases of clear cell carcinoma and 22 cases of non-transparent cell carcinoma in 61 patients. The evaluation indexes included age and sex, tumor size, margin and location. Whether there is bleeding, necrosis or calcification, the degree of enhancement of the lesion, enhancement and metastasis, etc. To explore the difference between the two types of renal malignancies. Results the calcification rate of 6 / 22 in patients with non-transparent cell malignant tumor was more than that of transparent cell carcinoma, which was more than 3 / 39 / 10. 038%. The clear cell carcinoma involved one pole of the kidney, while most of the non-transparent cell malignant tumor involved more than 2 renal poles. There was statistical difference (P 0.05). The enhancement of 19 non-transparent cell malignant tumors was significantly higher than that of clear cell carcinoma. In addition, in the renal cortex and medulla, There was significant difference in the enhancement degree of tumor between the two groups (P < 0.05). The diameter of the lesions of clear cell carcinoma and non-transparent cell carcinoma were 3.9 卤1.9 cm and 6.2 卤2.9 cm, respectively. The difference was significant (P = 0.023 3). The number of clear cell carcinoma was more than that of haemorrhagic cell carcinoma (P = 0.004). 19 non-transparent cell malignant tumors were enhanced inhomogeneously. However, only 2 clear cell carcinoma with poor blood supply were heterogeneous enhancement (P = 0.003). There was no statistical difference in the other evaluation parameters between the two groups (P 0.05). Conclusion the CT features of renal clear cell carcinoma and non-transparent cell malignant tumor have some difference. It can provide some information for differential diagnosis of both.
