Summary
Brief summary (as posted)
This project will conduct a large-sample, multi-center prospective clinical trial to further establish the safety and efficacy of BL-5ALA-PDT in preventing Non-Muscle Invasive Bladder Cancer (NMIBC) recurrence when compared to the usual postoperative perfusion chemotherapy regimen.

- Standard infusion chemotherapy (including gemcitabine, mitomycin, Epirubicin, etc.)
- description
- Standard infusion chemotherapy (including gemcitabine, mitomycin, epirubicin, etc.) was dissolved in 50mL normal saline or glucose and perfused into the bladder for 60min. Perfusion can be performed within 24 hours after surgery, and then once a week for a total of 8 times, and then once a month until 12 months after surgery.

- label
- BL-5ALA-PDT
- description
- Bl-5ala-pdt protocol: 1.5g 5ALA, dissolved in 50mL normal saline, was infused into the bladder for 2h before surgery and before each cystoscopy, and blue laser irradiation was performed under flexible cystoscopy at 30mW/cm2 for 21min. PDT was performed during the operation and at 3, 6, and 9 months after the operation.
