Detecting CREPT in Urine for Bladder Cancer Diagnosis and Monitoring

Summary

This study will, for the first time, establish a non-invasive diagnostic model for bladder cancer based on CREPT expression levels in exfoliated urothelial cells using a multicenter cohort, and validate its value in the non-invasive diagnosis and recurrence monitoring of bladder cancer. Its high sensitivity is expected to overcome the technical limitations of existing biomarkers and provide an innovative solution for establishing an integrated precision diagnosis and treatment system encompassing "screening, diagnosis, and monitoring."

Eligibility

Inclusion Criteria:

* (1) Patients diagnosed with or suspected of having bladder cancer; (2) Patients with benign urological diseases, including ureteral calculi, bladder calculi, cystitis, and ureteral stricture; (3) Consent to the use of experimental urine specimens and tissue specimens; (4) Aged 18 to 75 years; (5) Willing to sign informed consent, comply with the protocol, demonstrate good adherence, and cooperate with follow-up visits.

Exclusion Criteria:

* (1) History of other malignant tumors within 5 years or prior receipt of any anti-cancer treatment; (2) Urothelial carcinoma coexisting with other genitourinary tumors (e.g., renal cell carcinoma or prostate cancer); (3) Non-standard procedures for sample collection or storage; (4) Incomplete relevant information of the subject; (5) Patients with insufficient communication, comprehension, or cooperation, or poor compliance, who cannot guarantee completion of follow-up as required; (6) Subjects deemed by the investigator to be unsuitable for participation in this clinical trial for any other reasons, leading to withdrawal from the study.
