RESUMO
Objective To study the application and influential factors of urine tissue polypeptide specific antigen(TPS) for early detection and clinical outcome in bladder transitional cell cancers (BTCC). Methods Urine TPS in 76 cases of newly diagnosed BTCC,42 cases of recurrent BTCC,26 cases of postoperative BTCC with normal urine cytology,28 cases of benign bladder diseases,42 normal controls were determined by ELISA.The TPS levels were compared with the cystoscopic results and pathological findings.The relationship between urinary TPS level and the development and prognosis of BTCC was analyzed. Results The urine TPS level was not related to age and sex.The TPS levels in newly diagnosed BTCC group,recurrent BTCC group,postoperative BTCC with normal urine cytology group, bladder benign diseases group and control group were (341?403)U/L,(212?166)U/L,(168?115)U/L,(135?48)U/L and (81?37)U/L,respectively.There was significant difference between each other (all P
