Patients with multiple non-muscle-invasive tumours were randomized for a complete or incomplete transurethral resection (TURBT), followed by 3 IL-2 instillations. The primary end point was TTR. <b><i>Results:</i></b> These are the results of an interim analysis, which was performed due to slow accrual after which the study was closed prematurely. Twenty-eight patients were randomized of which 17 were eligible on an intention-to-treat basis. Median TTR or last follow-up was 3 months (interquartile range [IQR] 3–10 months) for the complete and 4 months (IQR 3–8 months) for the incomplete TURBT group. The TTR between the 2 groups did not differ significantly (log-rank, <i>p</i> = 0.54). ­<b><i>Conclusions:</i></b> These data do not support the hypothesis that a marker lesion enhances the therapeutic effect of IL-2 instillations in patients with NMIBC.
