Urine bladder tumor antigen stat in bladder tumor diagnosis: a meta-analysis / 中华泌尿外科杂志

ABSTRACT

Objective To systematic review bladder tumor antigen(BTA) stat in the diagnosis of bladder cancer. Methods MEDLINE, EMBASE, Cochrane Library, CMCC and CNKI were searched for studies about BTA stat in the diagnosis of bladder cancer. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by two reviewers using the designed extraction form. The software MetaDiScl. 4 was used to review management and data analysis. Results Seventy-one relevant studies were searched, of which 20 studies were included with 5929 patients involved and 51 studies were excluded. Heterogeneity (except for threshold effect) was found within these studies. A meta-analysis was performed using random effect model. Pooled accuracy indicators like sensitivity, specificity, positive likelihood ratio (LR), negative LR and diagnostic odds ratio (dOR) were 0. 64(95%CI 0. 62-0. 66), 0. 72(95%CI 0. 70-0. 73) , 2. 33(95% CI 2. 03-2. 68), 0. 48(95%CI 0.42 -0.55) and 5.12(95%CI 3. 88-6. 75), respectively. The sensitivity increased with tumor grades. The sensitivity of primary tumors was higher than the recurrent tumors. Area under curve (AUC) of SROC curve was 0. 7500 and Q* index was 0. 6934. Conclusions The performance of urine BTA stat is moderate in the diagnosis of bladder tumor. It can be an optional non-invasive test and an important adjunct test in preoperative detecting and postoperative monitoring of bladder tumor.
