BACKGROUND: Among patients with non-muscle-invasive bladder cancer (NMIBC), systematic reviews showed lower recurrence rate in patients treated with photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) than with white-light (WL) TURBT. However, the result is not consistent between clinical trials and the significance of preoperatively available factors in disease recurrence after PDD-TURBT remains unclear.
METHODS: The present study retrospectively analyzed 1174 NMIBC patients who underwent TURBT and were followed up for ≥ 6 months. Among 1174 patients, 385 and 789 underwent PDD-TURBT with oral 5-aminolevulinic acid (the PDD group) and WL-TURBT (the WL group), respectively. Recurrence-free survival (RFS) was compared between the PDD and WL groups before and after propensity score matching, and the impact of several baseline parameters on RFS between the 2 groups was investigated after matching.
RESULTS: Before propensity score matching, RFS was significantly longer in the PDD group than in the WL group (P = 0.006). After matching, 383 patients were included in both groups, and RFS was significantly longer in the PDD group than in the WL group (P < 0.001). In the cohort after matching, RFS between the two groups was compared in each subgroup classified according to baseline parameters, including age, sex, history of previous or concomitant upper urinary tract urothelial carcinoma, preoperative urinary cytology, tumor multiplicity, and tumor size, and significantly longer RFS was observed in the PDD group in all subgroups, except for the patients with tumors ≥ 30 mm (P = 0.21).
CONCLUSION: These results suggest that PDD-TURBT prolongs RFS in NMIBC patients, except for those with tumors ≥ 30 mm.
