Abstract:
Objective To assess the diagnostic value of combined testing of urinary bladder cancer antigen(UBC),hyaluronic acid(HA)and survivin in the detection of bladder cancer.Methods This study included 64 bladder cancer patients and 20 urinary benign disease patients.The examinations of urine UBC by enzyme-linked immunosorbent assay(ELISA),HA by radioimmunology assay,survivin by RT-PCR and urine cytology were performed in them.Results The sensitivity of UBC(85.9%,55/64),HA (89.1%,57/64)and survivin(93.8%,60/64)was significantly higher than that of urine cytology (40.6%,P＜0.01).The specificity of UBC,HA,survivin and urine cytology was 85.0%(17/20),80.0% (16/20),95.0%(19/20)and 95.0%(19/20),respectively;there was no significant difference among these 4 methods(P＞0.05).The sensitivity of UBC,HA and survivin was also significantly higher than that of urine cytology in different histologic stages and grades(P＜0.05).The sensitivity of UBC and survivin was not significantly different among different histologie stages and grades(P＞0.05).With regard to HA test, the sensitivity in G_2 and G_3 groups was significantly higher than G_1 group(P＜0.01),but there was no differ- ence between G_2 and G_3 groups(P＞0.05);and no difference among different histologic stages(P＞0.05). However,the sensitivity of cytology was improved with the higher grade of bladder cancer(P＜0.01);there was no difference among histologic stages(P＞0.05),By combined use of UBC,HA and survivin,both the sensitivity and specificity were 100%.Conclusions The study indicates that UBC,HA and survivin are better diagnostic markers for the early detection of urinary bladder cancer.These tests are simple,feasible and noninvasive with higher sensitivity and specificity.In addition,combined use of them can improve the diag- nostic sensitivity and specificity.
