Objective To determine if photodynamic blue-light'-assisted resection leads to lower recurrence rates in newly presenting non-muscle-invasive bladder cancer (NMIBC). Patients and Methods We conducted a prospective randomized trial of hexylaminolevulinate (HAL) photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumour (TURBT) plus single-shot intravesical mitomycin C vs standard white-light-assisted TURBT plus single-shot intravesical mitomycin C. A total of 249 patients with newly presenting suspected NMIBC enrolled at Guy's Hospital between March 2005 and April 2010. Patients with a history of bladder cancer were excluded. The surgery was performed by specialist bladder cancer surgical teams. Of the eligible patients, 90% agreed to be randomized. Results Of the 249 patients, 209 (84%) had cancer and in 185 patients (89%) the cancer was diagnosed as NMIBC. There were no adverse events related to HAL in any of the patients randomized to the intravesical HAL-PDD arm. Single-shot intravesical mitomycin C was administered to 61/97 patients (63%) in the HAL-PDD arm compared with 68/88 patients (77%) in the white-light arm (P = 0.04) Intravesical HAL was an effective diagnostic tool for occult carcinoma in situ (CIS). Secondary CIS was identified in 25/97 patients (26%) in the HAL-PDD arm compared with 12/88 patients (14%) in the white-light arm ((P = 0.04) There was no significant difference in recurrence between the two arms at 3 or 12 months: in the HAL-PDD and the white-light arms recurrence was found in 17/86 and 14/82 patients (20 vs 17%), respectively ((P = 0.7) at 3 months, and in 10/63 and 15/67 patients (16 vs 22%), respectively ((P = 0.4) at 12 months. Conclusions Despite HAL-PDD offering a more accurate diagnostic assessment of a bladder tumour, in this trial we did not show that this led to lower recurrence rates of newly presenting NMIBC compared with the best current standard of care.
