BACKGROUND: Photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) for nonmuscle-invasive bladder cancer is superior to conventional white-light TURBT for cancer detection. However, when performing PDD-TURBT, cystoscopy findings vary depending on the quality of the endoscopic equipment. In this study, we compared the effects of different types of endoscopic equipment on postoperative outcomes.
METHODS: Patients who underwent their first PDD-TURBT at our clinic were selected. Patients on whom PDD-TURBT was performed using endoscopic equipment A were sorted into Group A, and patients on whom PDD-TURBT was performed using equipment S were sorted into Group S. The characteristics, recurrence-free survival (RFS), and recurrence frequency of these patients were retrospectively investigated and compared. The prognostic factors for RFS were also analyzed.
RESULTS: A total of 49 patients were included in Group A and 46 in Group S. In Group S, a higher detection rate (8.2% vs. 30.4 %, p < 0.01) of carcinoma in situ (CIS) was noted. RFS tended to be better in Group S (HR 0.63, p = 0.15). The frequency of recurrence also tended to be lower in Group S (4.92 vs. 3.66 per 10,000 person-days, p = 0.08). Furthermore, CIS (HR 0.30, p = 0.04) and Bacillus Calmette-Guerin therapy (HR: 0.26, p = 0.01) were significant favorable prognostic factors for RFS.
CONCLUSION: The quality of the endoscopic equipment may influence postoperative recurrence after PDD-TURBT. Higher-quality endoscopic instruments have superior CIS detection capabilities, which can lead to improvements in postoperative outcomes with the appropriate selection of postoperative adjuvant therapy.
