Summary
Brief summary (as posted)
The goal of this observational study is to assess the safety and efficacy of trimodality bladder - sparing therapy in high - risk NMIBC patients. The main questions it aims to answer are: Is trimodality therapy safe and effective in the short term for high - risk NMIBC patients? What is its long - term effectiveness in terms of EFS, OS, and BI - EFS? How does it affect patients' QOL? Participants will be high - risk NMIBC patients receiving trimodality therapy at Peking University First Hospital. They will be observed to evaluate the therapy's effectiveness and impact on QOL using relevant assessment criteria and QOL scores.
