ImmunoCyt在膀胱移行细胞癌早期诊断中的应用

目的评价ImmunoCyt检测在膀胱癌早期诊断和随访中的作用. 方法膀胱癌患者86例,其中38例为膀胱肿瘤行经尿道膀胱肿瘤电切术后至少3个月的随访患者,48例有肉眼(镜下)血尿,分别进行标准尿脱落细胞学和ImmunoCyt检测.86例均行膀胱镜检查,对可疑组织进行活检. 结果膀胱镜检和病理证实28例为膀胱移行细胞癌.ImmunoCyt敏感性为82%,与尿脱落细胞学检查(39%)相比差异有显著性意义(P<0.05).两种检查方法相结合的敏感性为89%.ImmunoCyt和细胞学的特异性分别为78%和94%. 结论 ImmunoCyt较细胞学对膀胱肿瘤更敏感,二者联合使用可在保持高特异性的前提下提高诊断的敏感性,早期检测膀胱肿瘤.

Role of ImmunoCyt in the early diagnosis of bladder cancer

Objective To evaluate the effect of ImmunoCyt on the early diagnosis of bladder cancer by comparing the result of cystoscopy with that of cytology. Methods Eighty-six consecutive patients with bladder cancer (mean age,63 years) were included in this group.Among them 38 had undergone transurethral resection of superficial transitional cell carcinoma and had been followed up and 48 had hematuria.These patients were evaluated with standard cytology and ImmunoCyt test.Then all the patients underwent cystoscopy and suspected lesions were biopsied. Results Transitional cell carcinoma of bladder was confirmed pathologically in 28 cases.The sensitivity of ImmunoCyt (82%) was superior to that of cytology (39%, P <0.05).ImmunoCyt combined with cytology had the highest sensitivity (89%).The specificity of ImmunoCyt was 78% and that of cytology was 94%. Conclusions Sensitivity of ImmunoCyt is higher than that of cytology,and ImmunoCyt combined with cytology could improve sensitivity with high specificity in the diagnosis of the bladder cancer.
