However, the effective impact of ReTUR on oncological outcomes remains uncertain. We previously reported the feasibility and safety of replacing ReTUR with urine cytology (UC) and in-office flexible cystoscopy in selected T1 non-muscle-invasive bladder cancer. The aim of this study is to confirm our findings and present the associated oncological outcomes. METHODS: This is an ongoing prospective multicenter trial enrolling patients diagnosed with HG T1 BC from 5 Italian hospitals. In case of complete tumor resection at initial TUR, HG T1 patients underwent a strict follow-up consisting of UC at 4-6 weeks and an in-office flexible white-light and narrow-banding cystoscopy at 6-8 weeks. In case of a positive UC or evidence of recurrence at post-cystoscopy (PC) ReTUR was performed within 2 weeks. Otherwise, patients started the BCG induction course without any additional resection. Patients with a macroscopic incomplete initial resection or in case of absence of detrusor muscle underwent standard ReTUR within 40 days. RESULTS: Overall, 89 patients were enrolled between May 2020 and January 2023, of them 70 entered the protocol. Median age was 76 years (IQR 68-80). A total of 47 patients (68%) had negative UC and cystoscopy after TUR and thus started BCG directly while 23 (32%) patients had positive UC or cystoscopy and underwent PC ReTUR. With a median follow-up of 17.5 months (IQR 13.6-24), 18 patients recurred and 2 progressed. Considering the entire cohort, the 2-year RFS and PFS were 64% (95% CI: 46-76) and 97% (95% CI: 88-99), respectively. KM curves did not show differences in RFS between patients who avoided ReTUR and those who underwent PC-ReTUR (p=0.8). Not surprisingly, at Cox regression analysis concomitant CIS at diagnosis was associated with a higher risk of undergoing PC ReTUR (HR 5.3, 95% CI: 0.98-28.78, p=0.05). CONCLUSIONS: Our ongoing results confirm that avoiding initial ReTUR in HG T1 patients and selectively offering it promptly only to those with a positive cystoscopy or UC is not associated with worse cancer outcomes. Longer follow-up and larger sample sizes are necessary to validate these results.
