为探讨膀胱肿瘤患者早期诊断的有效方法，对112例怀疑或确诊为膀胱肿瘤的患者进行膀胱肿瘤抗原（BTA）测定。结果BTA诊断膀跳肿瘤的敏感性为77．4％，略低于膀脱镜检查（96．4％），但明显高于尿脱落细胞学检查（11．5％），同时，BTA的阳性率随着肿瘤的分级增加而增高。认为BTA测定是膀胱肿瘤早期诊断、预后监测较为灵敏的指标，并具有快速、安全、无创伤的特点，值得在临床上推广应用。
In order to explore an effective method for early diagnosis of bladder cancer patients, bladder tumor antigen (BTA) was measured in 112 patients with suspected or diagnosed bladder cancer. Results The sensitivity of BTA in diagnosing bladder tumor was 77.4%, which was slightly lower than that of bladder and abduction (96.4%), but significantly higher than that of urine cytology (11.5%). Meanwhile, the positive rate of BTA The rate increased as the tumor grade increased. BTA determination is considered early diagnosis of bladder cancer, prognosis monitoring more sensitive indicators, and has a fast, safe, non-invasive characteristics, it is worth to promote the clinical application.
