摘要
目的:研究膀胱内翻性乳头状瘤与膀胱移行细胞癌的超声特征及诊断价值。方法:选取在医院治疗的65例膀胱内翻性乳头状瘤患者纳入乳头状瘤组;另选取80例膀胱移行细胞癌患者纳入细胞癌组,比较两组超声特征差异,分析超声检查在病灶最大径、基底宽径与最大横径比值(B/T)以及病灶纵径与最大横径比值(L/T)定量参数的诊断价值。结果:乳头状瘤组患者的病灶最大径和B/T分别为(1.35±0.44)cm和0.83±0.19,明显低于细胞癌组,差异有统计学意义(t=-13.355,t=-5.104;P<0.05),而L/T为1.21±0.42,明显高于细胞癌组,差异有统计学意义(t=8.780,P<0.05)。乳头状瘤组患者的病灶位于侧壁比例、强回声、镶边征和血流丰富比例明显少于细胞癌组,差异有统计学意义(x^(2)=14.764,x^(2)=40.646,x^(2)=39.972,x^(2)=27.316;P<0.05),而钟摆征比例明显多于细胞癌组,差异有统计学意义(x^(2)=14.320,P<0.05)。病灶最大径、L/T和B/T诊断膀胱移行细胞癌的受试者工作特征(ROC)曲线下面积(AUC)分别为0.906、0.872和0.606,截断值分别为2.20 cm、0.85 cm和0.90 cm,灵敏度分别为83.00%、79.00%和66.00%,特异度分别为80.00%、75.50%和60.00%。Logistic回归分析中病灶最大径、L/T、病灶位于侧壁及血流丰富是发生膀胱移行细胞癌的影响因素(OR=1.744,OR=1.380,OR=1.992,OR=2.250;P<0.05)。结论:膀胱内翻性乳头状瘤与膀胱移行细胞癌超声特征有所差异,在鉴别诊断中有一定应用价值。
Objective:To investigate the ultrasonic features and diagnostic value of inverted papilloma and transitional cell carcinoma of bladder.Methods:65 patients with inverted papilloma of bladder who admitted to hospital were divided into papilloma group,and 80 patients with transitional cell carcinoma of bladder were divided into cell carcinoma group.The differences of ultrasonic features between the two groups were compared,and the diagnostic values of ultrasound examination in the quantitative parameters included the maximum diameter of lesion,the ratio of basal width diameter to the largest transverse diameter(B/T)and the ratio of longitudinal diameter to the maximum transverse diameter(L/T)were analyzed.Results:The maximum diameter and the B/T value were(1.35±0.44)cm and 0.83±0.19 in papilloma group,respectively,which were significantly lower than those of cell carcinoma group(t=-13.355,t=-5.104,P<0.05).While the L/T of papilloma group was 1.21±0.42,which was significantly higher than that of cell carcinoma group(t=8.780,P<0.05).The proportions of lesions located on lateral wall,strong echo,border sign and abundant blood flow in papilloma group were significantly less than those in cell carcinoma group(x^(2)=14.764,x^(2)=40.646,x^(2)=39.972,x^(2)=27.316,P<0.05),respectively,while the proportion of pendulum sign of papilloma group was significantly higher than that of cell carcinoma group(x^(2)=14.320,P<0.05).The area under curve(AUC)of receiver operating characteristics(ROC)curve of maximum diameter of lesion,L/T and B/T in diagnosing transitional cell carcinoma of bladder were 0.906,0.872 and 0.606,and the cut-off values of them were 2.20 cm,0.85 cm and 0.90 cm,and the sensitivities of them were 83.00%,79.00%and 66.00%,and the specificities of them were 80.00%,75.50%and 60.00%,respectively.Logistic regression analysis showed that the maximum diameter of lesion,L/T,location of lesions on lateral wall and abundant blood flow were the influencing factors of occurring transitional cell carcinoma of bladder(OR=1.744,OR=1.380,OR=1.992,OR=2.250,P<0.05).Conclusion:There are differences in ultrasonic features between inverted papilloma and transitional cell carcinoma of bladder,which has a certain of application value in differential diagnosis.
