Objective: The objective of this study was to report the 12-month oncological outcomes for patients with non-muscle-invasive bladder cancer (NMIBC) within the prospective, international COVIDSurg Cancer study. Patients and methods: Eligible patients were aged ≥18 years and scheduled for elective surgical management of NMIBC with curative intent (transurethral resection of bladder tumour [TURBT] or bladder biopsy) from 21 January to 14 April 2020. The primary outcome was disease recurrence within 12 months of previous elective TURBT/bladder biopsy. Secondary outcomes included disease progression within 12 months of previous elective TURBT/bladder biopsy, site-declared delay to surgery from diagnosis as a consequence of COVID-19 and deviation in standard care due to COVID-19. Comparisons were made to cohorts from the pre-pandemic era. Results: Bladder cancer accounted for 2.2% (n = 446) of patients in the COVIDSurg Cancer study, with data contributed by 27 centres across 12 countries internationally. Within this included cohort, 229 patients had NMIBC and 12-month follow-up data available. On application of National Institute for Health and Care Excellence (NICE) criteria, 47.2% were classified as having high-risk disease. Overall disease recurrence and progression rates were 29.3% and 9.7% at 12 months, respectively. In purely high-risk pre-pandemic cohorts, the International Bladder Cancer Group (IBCG) estimates a recurrence rate of 25% at 12 months, and the European Association of Urology (EAU) NMIBC 2021 scoring model estimates a 12-month progression rate of 3.5%. As a consequence of the COVID-19 pandemic, 10.9% of patients had site-declared delay to TURBT/bladder biopsy; 7.4% did not undergo intravesical therapy or had early discontinuation of this; 9.2% did not undergo early repeat resection for high-risk disease; and 18.3% had a delay to cystoscopic follow-up surveillance. Conclusions: This prospective study indicates that there were widespread deviations in usual care for NMIBC during the pandemic and that 12-month oncological outcomes appear to be impaired compared to published pre-pandemic outcomes.

Abstract
Objective: The objective of this study was to report the 12-month oncological outcomes for patients with non-muscle-invasive bladder cancer (NMIBC) within the prospective, international COVIDSurg Cancer study. Patients and methods: Eligible patients were aged ≥18 years and scheduled for elective surgical management of NMIBC with curative intent (transurethral resection of bladder tumour [TURBT] or bladder biopsy) from 21 January to 14 April 2020. The primary outcome was disease recurrence within 12 months of previous elective TURBT/bladder biopsy. Secondary outcomes included disease progression within 12 months of previous elective TURBT/bladder biopsy, site-declared delay to surgery from diagnosis as a consequence of COVID-19 and deviation in standard care due to COVID-19. Comparisons were made to cohorts from the pre-pandemic era. Results: Bladder cancer accounted for 2.2% (n = 446) of patients in the COVIDSurg Cancer study, with data contributed by 27 centres across 12 countries internationally. Within this included cohort, 229 patients had NMIBC and 12-month follow-up data available. On application of National Institute for Health and Care Excellence (NICE) criteria, 47.2% were classified as having high-risk disease. Overall disease recurrence and progression rates were 29.3% and 9.7% at 12 months, respectively. In purely high-risk pre-pandemic cohorts, the International Bladder Cancer Group (IBCG) estimates a recurrence rate of 25% at 12 months, and the European Association of Urology (EAU) NMIBC 2021 scoring model estimates a 12-month progression rate of 3.5%.
