摘要

Tissue polypeptide specific antigen (TPS) is the M3 epitope of the tissue polypeptide antigen, and a specific epithelial proliferation marker. To examine the benefit of urine TPS (U-TPS) measurement in the diagnosis and classification of biological properties of transitional cell carcinoma (TCC), a radioimmunoassay of U-TPS was measured in patients with active TCC (n = 56), at tumor-free status (n = 36), with inflammatory urological disease (n = 44), and age-sex adjusted normal subjects (n = 75). Both neoplastic and inflammatory urological diseases had an increase in U-TPS levels (U/ gm creatinine) compared to normal individuals (p = 0.0005), while it normalized in tumor-free condition (p = 0.007). For patients with active TCC, a strong positive association was observed between U-TPS values and both histological grading (p = 0.05) and positive cytology (p = 0.05). U-TPS levels were significantly higher in the presence of nodal or systemic metastasis (p = 0.008 by ANOVA test). Measurement of U-TPS appeared to be an indicator of poor outcome for patients with bladder cancer (p = 0.05 by t test) for a mean follow-up of 26 months. The results indicate that determination of U-TPS can be a supplement in assessing the biological properties of TCC, and may be helpful in identifying patients who need meticulous peri-operative staging survey.
