摘要
目的探讨肾透明细胞癌(ccRCC)CT征象与病理特征的关系。方法回顾性分析2017年6月至2018年6月我院收治的100例ccRCC患者的临床资料,均行CT检查,测量肿块平扫CT值和增强扫描三期(皮髓期、实质期及排泄期)最大CT值,计算皮髓期与实质期(△P1)、皮髓期与排泄期(△P2)、实质期与排泄期(△P3)的CT值差值及皮髓期/平扫CT值(△R1)、实质期/平扫CT值(△R2)、排泄期/平扫CT值(△R3),观察肿瘤假包膜、环形强化的有无,并与Fuhrman分级进行分析。结果低级别组与高级别组平扫CT值及增强扫描实质期、排泄期最大CT值比较,差异无统计学意义(P>0.05);低级别组皮髓期最大CT值高于高级别组(P<0.05);低级别组与高级别组△P1、△P3、△R3比较,差异无统计学意义(P>0.05);低级别组△P2、△R1、△R2均高于高级别组(P<0.05);低级别组与高级别组坏死、钙化比较,差异无统计学意义(P>0.05);低级别组与高级别组假包膜和环形强化的比例比较,差异有统计学意义(P<0.05);低级别组肿瘤直径小于高级别组(P<0.05)。结论ccRCC的CT征象与病理特征有关,CT征象有助于鉴别低、高级别ccRCC。
Objective To explore the relationship between CT signs and pathological features of clear cell renal cell carcinoma(ccRCC).Methods The clinical data of 100 patients with ccRCC admitted to our hospital from June 2017 to June 2018 were retrospectively analyzed.CT examination was performed,and the CT value of mass plain scan and maximum CT values in three phases of enhanced scan(corticomedullary phase,parenchymal phase and excretory phase)were measured,the CT value differences of corticomedullary phase and parenchymal phase(△P1),corticomedullary phase and excretory phase(△P2),parenchymal phase and excretory phase(△P3),and the corticomedullary phase/plain scan CT value(△R1),parenchymal phase/plain CT value(△R2)and excretory phase/plain CT value(△R3)were calculated,and the tumor pseudocapsule and presence or absence of enhancing rim were observed,and Fuhrman classification was used for analysis.Results There were no significant differences between low-grade group and high-grade group in the plain scan CT value and the enhanced scan maximum CT values in parenchymal phase and excretory phase(P>0.05).The maximum CT value in corticomedullary phase in low-grade group was higher than that in highgrade group(P<0.05).There were no significant differences between low-grade group and highgrade group in the△P1,△P3 and△R3(P>0.05).The△P2,△R1 and△R2 in low-grade group were higher than those in high-grade group(P<0.05).There were no significant differences between lowgrade group and high-grade group in the necrosis and calcification(P>0.05).There were statistically significant differences between low-grade group and high-grade group in the composition ratios of pseudocapsule and enhancing rim(P<0.05).The tumor diameter in low-grade group was lower than that in high-grade group(P<0.05).Conclusion CT signs of ccRCC are associated with pathological features,and CT signs are helpful in identifying low-grade and high-grade ccRCC.
