Introduction: Standardized methods of reporting complications after radical cystectomy (RC) and urinary diversions (UD) are necessary to evaluate the morbidity associated with this operation to evaluate the modified Clavien classification system (CCS) in grading perioperative complications of RC and UD in a real life cohort of patients with bladder cancer. Materials and methods: A consecutive series of patients treated with RC and UD from April 2011 to March 2012 at 19 centers in Italy was evaluated. Complications were recorded according to the modified CCS. Results were presented as complication rates per grade. Univariate and binary logistic regression analysis were used for statistical analysis. Results: Results and limitations: 467 patients were enrolled. Median age was 70 years (range 35e89). UD consisted in orthotopic neobladder in 112 patients, ileal conduit in 217 patients and cutaneous ureterostomy in 138 patients. 415 complications were observed in 302 patients and were classified as Clavien type I (109 patients) or II (220 patients); Clavien type IIIa (45 patients), IIIb (22 patients); IV (11 patients) and V (8 patients). Patients with cutaneous ureterostomy presented a lower rate (8%) of CCS type IIIa ( p ¼ 0.03). A longer operative time was an independent risk factor of CCS III (OR: 1.005; CI: 1.002e1.007 per minute; p ¼ 0.0001).

A large majority of high-volume centers performing PN and LDN use mannitol for renoprotection. Since there are no data proving its value nor standardized indication and usage, this survey may provide information for a randomized prospective study.

5012 Background: Cisplatin-based neoadjuvant chemotherapy (CT) followed by radical cystectomy (RC) is a standard treatment for MIBC. PD-1/L1 inhibitors as single agent induce pathological complete responses (pCR) in this setting. Predictors of response are still ill defined. DUTRENEO trial aimed to prospectively explore the activity of anti-PDL1 + anti-CTLA4 vs CT in pts selected according to a tumor pro-inflammatory IFN-gamma signature (tumor immune score, TIS). Methods: Cisplatin-eligible pts with urothelial MIBC (cT2-T4a, N≤1, M0) candidates to RC were classified as “hot” or “cold” according to a tumor TIS determined by Nanostring technology. Patients with "hot" tumors were randomized to DU 1500 mg + TRE 75 mg every 4 weeks x 3 cycles or standard cisplatin-based CT (GEMCIS or MVACdd). Pts in the “cold” arm received standard CT. Primary endpoint was to achieve ≥8 pCR in the DU+TRE arm. PDL1 expression was assessed using immunohistochemistry. Results: 61 pts were recruited in 10 sites between oct-2018 and dec-2019. Pts randomized in the “hot” arms received standard CT (n = 22) or DU+TRE (n = 23) and had a pCR rate of 8/22 pts (36.4%) vs 8/23 pts (34.8%), respectively [OR = 0.923 (0.26 – 3.24)]. In the “cold” arm, 16 pts received CT obtaining a pCR rate of 68.8% (11/16 pts). There were more PDL1 low tumors in the "cold" TIS arm (10/12, 83.3%). pCR rate by PDL1 status is shown in the table. One pt in the DU+TRE arm refused RC. Full treatment was delivered to 81.3% of CT "cold" vs 59.1% of CT "hot" vs 73.9% in the DU+TRE arm pts. Grade 3-4 toxicities were more frequent in the CT arms. Conclusions: The combination of DU+TRE is safe and active in MIBC patients in the neoadjuvant setting. Nevertheless prospective stratification by a pro-inflammatory IFN-gamma signature failed to select patients more likely to benefit from IO vs CT in this context. Further studies are required to guide treatment selection. Clinical trial information: NCT03472274 . [Table: see text]

Purpose To determine how members of the Société Internationale d'Urologie (SIU) are continuing their education in the time of COVID-19. Methods A survey was disseminated amongst SIU members worldwide by email. Results were analyzed to examine the influence of age, practice region and settings on continuing medical education (CME) of the respondents. Results In total, 2494 respondents completed the survey. Internet searching was the most common method of CME (76%; all ps < 0.001), followed by searching journals and textbook including the online versions (62%; all ps < 0.001). Overall, 6% of the respondents reported no time/interest for CME during the pandemic. Although most urologists report using only one platform for their CME (26.6%), the majority reported using ≥ 2 platforms, with approximately 10% of the respondents using up to 5 different platforms. Urologists < 40 years old were more likely to use online literature (69%), podcasts/AV media (38%), online CME courses/webinars (40%), and social media (39%). There were regional variations in the CME modality used but no significant difference in the number of methods by region. There was no significant difference in responses between urologists in academic/public hospitals or private practice. Conclusion During COVID-19, urologists have used web-based learning for their CME. Internet learning and literature were the top frequently cited learning methods. Younger urologists are more likely to use all forms of digital learning methods, while older urologists prefer fewer methods.

Objective: : To determine whether there are significant differences in oncological outcomes between three different bacillus Calmette-Guérin (BCG) strains used for adjuvant intravesical immunotherapy in patients with high-grade T1 (T1HG) non-muscle-invasive bladder cancer (NMIBC). Patients and methods: : Data of 590 patients with a diagnosis of primary T1HG NMIBC were retrospectively reviewed. The study included 138 (23.4%) patients who were treated with the Moreau, 272 (46.1%) with the TICE, and 180 (30.5%) with the RIVM strains. All patients included in the analysis received at least five instillations of an induction course and at least two installations of a maintenance course. Due to existing differences in baseline patient characteristics, the association between oncological outcomes and strain groups was investigated by complementary analysis with the implementation of inverse probability weighting (IPW). Results: : The 5-year recurrence-free survival (RFS) rate was 70.5%, 66.7% and 55.2% for the Moreau, TICE and RIVM groups, respectively (P = 0.016). The 5-year progression-free survival (PFS) rates were 84.4%, 85% and 77.8% in the Moreau, TICE and RIVM groups, respectively (P = 0.215). The IPW-adjusted Cox proportional hazard regression analysis did not show any differences in RFS between the Moreau and TICE groups (P = 0.69), whereas the RIVM strain was significantly associated with worse RFS compared to the Moreau (hazard ratio [HR] 1.69 for RIVM; P = 0.034) and TICE (HR 1.87 for RIVM; P = 0.002) strains. The IPW-adjusted analysis did not show any significant differences between study groups in terms of PFS. Conclusions: : The results of the present study suggest that the Moreau and TICE strains might be superior to the RIVM strain in terms of RFS in patients with T1HG NMIBC.
