Active Surveillance行为干预

Patients undergo protocol-defined surveillance after achieving tumor-free status, including cystoscopy, biopsy as clinically indicated, urine cytology, urinary tumor DNA testing, and imaging assessments, without continued systemic PD-1/PD-L1 inhibitor therapy unless disease recurrence or progression occurs.

PD-1/PD-L1 Inhibitor-Based Systemic Immunotherapy药物

Patients continue protocol-defined systemic PD-1/PD-L1 inhibitor therapy after achieving tumor-free status for up to approximately 1 year, with ongoing surveillance including cystoscopy, urine cytology, urinary tumor DNA testing, and imaging assessments.

研究简介（原文）

Patients with extensive transurethrally unresectable very-high-risk non-muscle-invasive bladder cancer (NMIBC) may achieve a tumor-free status after systemic immunotherapy-based bladder-sparing treatment combined with transurethral resection of bladder tumor (TURBT). However, the optimal duration of systemic immunotherapy after achieving a tumor-free status remains uncertain. Prolonged treatment may increase toxicity, treatment burden, and cost, while some patients may maintain durable disease control without continued therapy. This randomized study aims to evaluate whether active surveillance after achieving tumor-free status is a feasible alternative to continued systemic immunotherapy in patients with extensive transurethrally unresectable very-high-risk NMIBC. Patients will initially receive systemic immunotherapy-based treatment followed by disease evaluation using cystoscopy with biopsy and/or TURBT, urine cytology, urinary tumor DNA (utDNA), and imaging assessments. Patients who achieve tumor-free status after treatment and complete resection of visible disease will be randomized to either active surveillance or continued systemic immunotherapy. The study will evaluate recurrence outcomes, bladder preservation, progression, safety, and patient management strategies following achievement of tumor-free status. The trial also aims to explore the role of urinary tumor DNA in identifying patients who may safely undergo treatment de-escalation and active surveillance.

Dear Study Team,

I am a patient in China and I am interested in participating in your clinical trial:

Study Title: Is Prolonged Systemic Immunotherapy Necessary After Achieving Tumor-free Status in Patients With Extensive Transurethrally Unresectable Very-high-risk NMIBC?
ClinicalTrials.gov Identifier: NCT07625527
Sponsor: Tianjin Medical University Second Hospital
Investigational product: Active Surveillance, PD-1/PD-L1 Inhibitor-Based Systemic Immunotherapy

About me:
- Age: (please fill in)
- Sex: (please fill in)
- Confirmed diagnosis and stage: (please fill in)
- Biomarkers / genetic testing: not available
- Prior and current treatments: (please fill in)
- Performance status (ECOG): not assessed
- Current location: China

Could you please let me know:
1. Whether I might be eligible for this study;
2. Which site would be closest and most practical for me, and whether remote pre-screening is possible;
3. What documents (medical records, pathology or imaging reports, recent labs) I should prepare for pre-screening.

I can provide English translations of my medical records. Thank you very much for your time and help.

Kind regards,
