Summary
High levels of tissue polypeptide antigen (TPA) indicate a higher risk of bladder cancer recurrence. This biomarker shows prognostic value for predicting tumor relapse in superficial bladder cancer patients.
Area of Science:
- Oncology
- Urology
- Biomarkers
Background:
- Superficial bladder cancer (SBC) presents a significant risk of recurrence.
- Accurate prognostic markers are crucial for managing SBC and predicting patient outcomes.
Purpose of the Study:
- To investigate the prognostic value of tissue polypeptide antigen (TPA) levels in predicting tumor relapse in patients with superficial bladder cancer.
- To evaluate the association between TPA levels, tumor invasion, and differentiation in relation to cancer recurrence.
Main Methods:
- A cohort of 133 superficial bladder cancer patients (Ta and T1 stages) were analyzed for TPA levels.
- Tumor differentiation (well, moderately, undifferentiated) was assessed.
- Statistical analyses, including univariate and multivariate approaches, were employed to assess prognostic factors for tumor relapse.
Main Results:
- High TPA levels were detected in 25% of patients, with no significant correlation to tumor invasion depth or differentiation.
- Tumor relapse was observed in 43 cases during an average follow-up of 8.3 months.
- Tissue polypeptide antigen (TPA) emerged as the sole significant prognostic factor, with high TPA levels associated with a 2.03 times increased risk of relapse.
Conclusions:
- Tissue polypeptide antigen (TPA) is a valuable independent prognostic marker for predicting recurrence in superficial bladder cancer.
- Monitoring TPA levels may aid in risk stratification and personalized management strategies for bladder cancer patients.
