研究目的
To assess the effectiveness, safety and feasibility of Holmium laser fulguration in an outpatient regimen for selected tumours in patients with a history of low-risk bladder cancer and recurrence of small papillary tumours.
研究成果
Holmium laser fulguration with mitomycin C instillation in an outpatient regimen is a safe and feasible alternative to transurethral resection for selected low-risk bladder cancer recurrences. Recurrence after a second fulguration occurs earlier, suggesting a higher risk of progression, and transurethral resection is recommended in such cases.
研究不足
The study does not allow for histological analysis due to the fulguration method, potentially missing progression details. It is limited to selected patients with low-risk tumors and may not be generalizable to all cases. The follow-up median was 17 months, which might be insufficient for long-term outcomes.
1:Experimental Design and Method Selection:
A prospective, longitudinal cohort study was conducted from January 2009 to December
2:The study used Holmium laser fulguration with subsequent instillation of mitomycin C in an outpatient regimen. Sample Selection and Data Sources:
20 59 patients with a history of low-risk bladder cancer and recurrence of small papillary tumours were included based on specific criteria (e.g., papillary neoplasm ≤10 mm, ≤5 implants, negative cytologies).
3:List of Experimental Equipment and Materials:
Holmium laser with 365 nm fiber, cefuroxime antibiotic, lidocaine gel and solution, mitomycin C, flexible cystoscope.
4:Experimental Procedures and Operational Workflow:
Patients underwent local anesthesia, flexible cystoscopy, laser fulguration with energy settings of
5:5-1J and frequency 5-10 pulses, hemostasis, catheterization, instillation of mitomycin C, and discharge after confirming no hematuria and spontaneous urination. Data Analysis Methods:
Descriptive data analysis and Kaplan-Meier curves for relapse-free time analysis using SPSS v.23, with Log-Rank test for statistical significance.
